rb25det vs. 2jz

[redgold]

i have a 93 240sx and thinking about doing a swap...thinking about either the rb25det or the 2jz-gte with the NA tranny...which swap would be better as of power wise...thinking about only 500 hp....

also...which swap would be easier and would be more affordable???...i know that on 2jzswap.com, they have a kit for the 2jz to fit into the 240sx...but that is just the kit though...no motor no tranny yet...

need help on ur opinions...thanks...

[drftwerks]

2J all the way,

easier to find and cheaper parts,

rb25?? fuck that

if going rb go all the way

[kerosinek]

RB25 will be a lot cheaper. 500 HP is no problem for either engine. I say
2J because it isnt a very common swap.

[OptionZero]

counting down until drift freaq arrives...

[Ghost Dancer]

Have you considered the 1JZ? It's more on par with the RB25 price range.

[JtWo]

2jz simply because it sounds so much more sexier when it's revving high. Also, it makes oodles of hp with simple bolt ons. You can get about 450 just with bolts ons. Also, considering the stock internals can hold more than 700hp, I think it's an all go thing.

[mmdb]

2J all the way,

easier to find and cheaper parts,

rb25?? fuck that

if going rb go all the way

Well said. Btw you see that 9 sec s14 + 2jz roaming around?

[FaLKoN240]

2JZ's are cool, if you're RICH.

Are you rich? If not, stop, and reconsider. Pricing together a swap kit, and an actual JZ clip are wayyy different from RB swap, which is expensive as well.

[LB.Motoring]

Yah, plus its even more, you have to factor in, Now with the 2J you have to make fab'd mounts, if you dont go premade mounts for rb...

450-500 hp, i would go rb, well im Rb basied, haha rbtwofive in my chassis.

I would just push stock internals on the rb, run uped injectors, both manifolds. FMIC. and your choice of a GT, with a decent tune you should be within your "hp Range" for god knows what you wanna do with it. I love it. 500hp is the goal. screw suspension :keke:

GL.

[redgold]

what EMS are u running??? with the RB of course...

[LB.Motoring]

RB: Apexi Power FC with commander and electronic attached boost controller.

[kouki_s14]

and here's a rush of the RB owners.

Both motors are great, both can do 500hp easily(with the right amount of funds). it's all a matter of preference. I think the RB would just be a overall easier task, 2J probably has a lot more custom work then a set of mounts. Anyways it's your car do what you will.

Dave, you can take it from here...

[SimpleS14]

Go with the RB25DET.....


I would also say that you could consider the 1JZ (as someone mentioned)...but custom work is required.

[JesusFreakDrifter]

stay true to nissan, RB is an easier swap than the 2jz, one because of the wiring, which can easily make you its bia, but be unique as well, never conform, GOD BLESS

[redgold]

for the guys that have done that swap with the rb25det...is it just an drop like the sr20 or is it more difficult???...is it okay just by getting the swap itself or is getting the front clip better???...

[drift freaq]

2J all the way,

easier to find and cheaper parts,

rb25?? fuck that

if going rb go all the way

Hahahahahaha this is just the biggest joke I have heard yet. 2JZ easier to find? Excuse me are you living in Japan. 2JZ in the United States is a very expensive engine and its not that common.
Oh wait your going to recommend the IS300 engine right? EHhhhhh. FAIL!!! The only U.S. 2J worth putting in would be the Supra engine. Extremely hard to find and expensive.
Doing the install? more work. Great engine lots of power capability. Everything else is stated above.
Fuck the RB25? Driftwerks thats a very poor statement for a retailer to be making and also uneducated.
Now with the RB's you have several different brands of install kits to choose from, parts availability is getting larger by the day.
How much money do have? If your on any kind of budget then a RB25 is the easiest way to go.
If money is no object than do a 26 either way I can get the best install kits on the market for them. Plus wiring service if needed.
Do you know what 500 hp is like a a S series chassis? What are you going to use the car for drag racing?
Seriously I am running a RB25 with a HKSGt2535 turbo, Greddy intake,Q45 throttle body and PowerFC with Blitz SBC ID boost controller and at 11lbs of boost I am putting down over 300hp at the wheels. The car is very fast. I am capable of putting down roughly around 360 whp. I can tell you that 500 whp and your car is not going to be that streetable given its weight.
Lets get back to it though. RB25 clips are anywhere from $2500-3000 install kits are $1100 wiring is $335-375. Thats a pretty good bang for the buck before your bolt ons. Oh ya I was putting down 240whp at 5-6lbs of boost with a stock ecu before I had my boost controller and that was dynoed.
Don't let fools tell you the RB25 is not worth it. If you can't afford doing a 26 which will wind up costing you around 10k to do the swap then the RB25 is a great way to go.
Nothing against 2J's just a reality check from the financial side of things.

[kouki_s14]

how should i put this...

if you can do an SR yourself a RB really isnt any harder. there are little nit pick things, but nothing major.

I would get a clip for the same reason people get SR clips. you can get extra stuff and you can be almost positive nothing will be missing. Plus if you use the Syko RB25 install kit you will need the RB crossmember

[drift freaq]

for the guys that have done that swap with the rb25det...is it just an drop like the sr20 or is it more difficult???...is it okay just by getting the swap itself or is getting the front clip better???...
get the clip, with the Syko performance kit its very much a drop in affair. With the clip you get the R33 crossmember which is the way to go. You also get everything so if you don't want to front mount intercooler right way you can run the side mount and save money.

[!Zar!]

Dave has said everything that needs to be said, but the origonal poster should've searched.

Nubs post the same question over and over acting like they plan on doing some crazy swap.


I'll say it straight up, I'm near sure the poster won't go through with this swap.

He can't spend the time to search. What should make me believe that he has the patience and skill to find a propper clip, wire the harness and, install the motor.

Right now, I see this thread as a joke.


But to shead light on your little nub dreams.

Purchace the rb install kit from syko performance. Then have them wire up a harness for you.

Out of all the rb swaps I've seen, theirs is the best fitting/quality.

[redgold]

no drifting with this set up...

[s13silady]

if you go RB, then like what Zar, said use the syko kit. you will have to swap out to the skyline crossmember. but the fitment is superb.

i have a neo 6 right now... but if i could it all over again, i would have gone 2jz. *sigh*

[redgold]

what is the difference from the Neo 6???...seems much more expensive...

[drftwerks]

i never said anything about is300, the na 2J is a joke, i dunno i guess here locally in bay area a 2J engine set, is not taht hard to find, esp with the 5 spd and not the 6 spd, in ca its also more logical choice, for possibly legal swap. although he is not in CA, so it doesnt mater much to him.

honestly i dont event think you can compare a RB 25 to a 2J, i do believe they are on different levels.

i just think the RB26 and the 2J are more realistic comparison than a RB25 and 2J, that bieng said yes the RB25 can be fun, but, 2J would be easier to build it to 500.

lookign back to his first post, eh, probably shouldnt be considering any swap till he can make sure no expenses are cut, cause thats when things start going wrong.

OH BTW to the orig poster,

EASY, AFFORDABLE, SWAP, and 500 hp do not belong in the same post..............

RYAN!, where were you last weekend when i was up there?

edit back on topic

we have answered all your questions, so decide for yourself. Build the car for yourself, i dont get why people want opinions on this kind of stuff. Do you not have a mind for yourself or you just wanna seek approval from forum members? Has this turned into a popularity contest? Again DO WHAT YOU WANT TO DO.

[kerosinek]

Chevy 350, gobs of power, weighs less than the KA24DE, and when you are ready, vortech!

[drftwerks]

ohh and yea bro 500 hp in S13??

i hope this car is for D1 and you are a pro driver,


or slicks and a ford 9" rear end

[Ghettokracker71]

Keep your nissan,all nissan. NO point in wasting time and money putting in a swap from another company when PLENTY of great swaps are available from the right company, I would understand this thread being valid if we were talking about a fiat or MG or something that doenst really have any decent motor choice,but we're talking about a fucking NISSAN.

Go with an RB,hands down.

[atom]

Who makes what engine, keep it in the Nissan family, who cares. 2JZ is hot, but expensive. Especially the Getrag, ugh. I say get the 2JZ, since this thread was obviously started by a dreamer who 99% most likely won't do either..........

Byron, you cannot tell someone just to forget the RB25 or say the 2JZ swap is cheaper. You may have lucked out in general finding one or two 2JZ's, but in general they are not common and do cost a lot more.
Yes the 26 and the 2JZ are more on the same level but to just blatantly dismiss the 25 like you did was a poor judgement call on your part.
Both the 26 and the 2JZ swaps are not for the poor or limited budget person.
Yes the truth is if your going for straight up 500 HP the 26 or 2jz would be the way to go in the proper context. That being for the money you would spend on getting the 25 up there you could just go down the road of the 26.
Now on to the fact that IMHO for the sake of a Six run a Nissan in a Nissan. For the sake of a V8 well that could go any number of directions.
Though for the person on a budget who wants 300-400HP with more torque and drivability than any SR is going to give you at that level the 25 is a pretty damn good way to go.
Now once getting into the 400hp and above range then yes go 26.
Though in the end you made unqualified statements with no facts to back them up. I.E. uneducated statements based solely on assumption and opinion rather than actual fact.
You only tried to come back with facts and weak ones at that after you were called on it.

[coreansurfer]

i have an rb25det, very sexy, not too expensive for the swap, but if i had the money ls7 baby!! yes i know, flame on!

[sil80tydriftmachine]

a 2jzgte automatic is easy to find not a 6 speed and if you get one it be over 5,000 easily if you want a straight six then do a rb25 or 1jzgte 2jzgte parts are very expensive yes you get lots of power from bolt on but bolt ons are expensive for this car trust me i know i own one and ive spend over 30k into it alone in the motor

[drftwerks]

Drift freq, correct i do have limited knowlegs and exp with the RB series, and i concede, i have nothing to prove, or no ego to protect.


done

haha

[Dousan_PG]

2jz? no way
1jz vs RB25 is more likely
i looooove 1jzs
wow
so hot

but of the two, i'd go 25 vs 2jz
2zj is BANK!

[redgold]

aight...thanks guys...i know what i am going to do now...

[articdragon192]

Please tell me you decided to go KA-T :D

[redgold]

hehehehe...naw naw man...i will be going rb25det in my 240sx...i was thinking about this swap before all this already...after the help...made it an 100% decision...aight...laters...

[P4rD0nM3]

If you're still asking which swap do you need, I think you need to just go with rb25det...

[drift freaq]

isn't this thread over yet? I think its been beaten down.

some cool 2jz/silvia vids... im sorry but that sound is just sooo attractive and you couldnt even get that with a rb26

[mr_240sx]

im sry but when performing a swap, most of us dont swap an engine because of its sound.............

[crazy9ceguy]

2jz is very expensive, u can find the 2jz vvti motor for about 2500-3000 with the turbos, and about $3300 for the getrag 6 speed V161 from japan with about 10k miles on it.

[jaymelz324]

the 1jz can be had for the same amount as the rb25, if you do it yourself, it may even be cheaper

[jaymelz324]

im sry but when performing a swap, most of us dont swap an engine because of its sound.............
yes i do know this, but what i dont know, is your point? For some, the sound of the motor may be the deciding factor between, say a 1jz and a rb25....And yes the 2jz is expensive, but the 1j isnt and the 1j will b supple enough for 500 plus hp so if your goals are near that, than the 2j isnt worth it. And please dont say the rb can handle that because a 1j with 500 on stock internals will last longer than an rb25 with 500 on stock internals and its been proven. Also mod for mod, the 1j clearly makes more power and you can use the 7mgte tranny with the 1jz bellhousing. Plus it has a map sensor :wackit:

[ranger2339]

Dude i see you are in MN, i am in stillwater and we could do a swap for you if you want.


I would say 110% go with the 2jz or if your on a little budget go 1jz..I have a 1jz in my MKIII just some BPU stuff (intake,exhaust and a blitz ECU) and i made 335whp on 15lbs on pump gas BTW!

You need the install kit from www.2jzswap.com,2jz with a front sump oil pan usdm or the jdm 2J will be fine(the only diff from the usdm and the jdm 2J is the INJ.,ECU,cams,turbos and the JDM one is MAP ran) if you switch those out it will be the same engine.ECU and harness (you can also use the 1JZ harness and ECU on a 2JZ),custom IC kit,a R154 (the 1jz tranny from a soarer or mod. the shifter linkage needs to be longer if you wanna use the non soarer R154 or the R154 from the turbo supra MKIII (if you use the r154 from the turbo MKIII you need a 1JZ bellhousing and the shifter linkage mod)
Then wire it up, all in all it takes about 5 wires to get the JZ series engine to run and would be very very easy to wire up...

I say go with a 1JZ but if you want a 2JZ soo bad go with the 2JZ engine with the R154 tranny..

IMO the 2JZ owns and you will be very happy with it, fuck bolt on a single turbo kit,EMS/tuning,fuel and you can get 600whp no prob and the stock engine!

[Maurder]

the 2jz is a extreemly bolt on savy motor and there are tons and tons of parts for them. RB's are becoming more popular with the 240's wich use to be unique, id hit up the 2jz or 1jz to go even more unique now, and none the less they sound freakin sweet.

[92FireCoupe]

i'll second this dude, besides, WTF would you want to put a Toyota engine your Nissan!?!?! RB25DET=whole helluva lot easier!(this is according to what i've read is entailed in the 2JZ swap on the internet.) I'm about to start mine, and I hope that I can find all the info I need on here because i'm going to do it myself. w00t to everyone with a nissan engine in their nissan car.:werd:

[jaymelz324]

thats the most stupid reason not to put a more stout engine into a car....Because its not Nissan????? wut the hell does that have to do with how well the engine will perform? You take the whole purebread nissan thing a little too serious and hopefully you will realiize someday that this is a sicker swwap than any rb25 any day buddy.. look at the times of a stock rb25 s13 vs stock 1jz s13... your lookin at mid 13's vs high 12's. A stock 1jz would beat a stock rb25 and its the same amount of work. Driveshaft, mounts, x-member, wiring etc... What is so much harder about the 1jz? Do some research before u say things that arent true and make u look like u dont know wat your talking about

[Aoshi112]

You know I also wouldn't discount the 2JZ-GE just yet either. It's cheap and readily available and the stock bottom end is pretty damn strong. Take a look here: http://supraforums.com/forum/showthread.php?t=350965 and if you check the dyno section of clubna-t.com http://www.clubna-t.com/forums/showthread.php?t=354 this guy did almost 400rwhp on the stock headgasket. However the newer VVTI 2JZ-GEs in the IS300s are a bit weaker, just be sure to find something a bit older and non VVTI. Drop in a new headgasket and turbo kit and you're set to go. I don't know, something to think about.

Edit.

Forgot to add, DaveH went 9s on stock bottom end with a 3mm headgasket with ARP head studs in 2004.

http://supraforums.com/forum/showthread.php?t=202029&highlight=headgasket

:)

Not too shabby for a 2JZGE-T

[jaymelz324]

yes you are very right and those sights are helpful. The ge motor is also a very stout motor that will make better torque than both the 1j and the 25

And please dont say the rb can handle that because a 1j with 500 on stock internals will last longer than an rb25 with 500 on stock internals and its been proven. wackit:

What experience on RB25's do you have to back up that statement? There's only a few RB25's in the country with over 500whp and I'm sure there's none on Long Island....

[jaymelz324]

I couldnt tell you exactly where i read it, but i have read it on a nissan forum that it wouldnt last too long pusshing 500whp on stock internals. On the other hand, on supraforums, go to the mkiii/1jz section and look at the top hp list...Most of those guys are over 500 and are on stock internals.

[eh?]

So basically you have no experience (have you even seen a RB25 swapped 240?) and you don't know what you talking about.
There are too few RB25 swaps let a lone properly running RB25 swaps to make ANY judgement.

[jaymelz324]

ummm no ur wrong. I DO know what i am talking about. I wont lie, i go by the figures that people post on forums but to me, thats good enough because its not like many ppl lie about the numbers their puttin down especially when they have dyno's to prove. tell me im wrong. And there are more and more rb25 swaps by the day and many forums about the swap so i think there is more than enough to judge so wat r U saying?

[Vagrant02_DRFT]

like everyone said. the RB25 is a lot cheaper. the good thing about the 2J is that it has a little more power. parts are easy to find. its a very very strong engine. 500HP on a 2J is very easy. same with the RB. the RB is a stront engine to but im saying go with the 2J. it may cost a lot but its wourth it at the end.

Just because someone on a forum SAID the RB25 won't last with 500whp doesn't constitute FACT. When someone posts their RB25 FAILED at 500whp that would be considered FACT. Understand? Learn to wade through the bullshit and hear-say.
Show me a post on a forum where an RB25 swap failed above 500whp...

[jaymelz324]

its not just one time. Im a member of a few supra, 240sx, mr2 etc forums and ive read multiple times that the rb can handle that power. But most recommend not to, because it wont last too long. Ive read this more than enough times to bellieve it. And ive never read anything about tthe 1jz having problems with that much power. There are a bunchh of em puttin out over 500 with the stock block with no problems because for the most part, the 1jz bottom end is very very similar to the 2jz bottem end making it a bulletproof motor. And i dont feel like arguing with u so wutever, the kid that started the thread prolly already installed his engine and forgot about this thread lol

[eh?]

Yes the thread is dead.
But you proved my point , you can't show me an RB25 failure thread/post anywhere. I just found it funny you told the other guy to do research. You don't do research by reading forum hear-say.

[drift freaq]

You know whats funny about this thread? Its the fact that a short of the guy in Texas who posted pics from his dyno day experiences, most of you have not even tasted 500hp in a 2800 pound car. Your argueing a point thats useless and impratical. 500hp in a S series chassis is pretty close to track only situation. Do you know how much tire you would need in the rear to keep that on the ground?
My S13 right pushes somewhere in the area of just over 300whp at 11lbs. and my turbo will be maxed at 375-400 crank.
I can tell you honestly the car is god awful fast already. You guys forgot we are talking 6 cylinders here which means torque monsters. That adds to the whole hard time keeping the thing on the ground.

Now to jaymelz, do not persist in pushing this thread any farther. You do not have actual facts and are just posting hearsay off of what you have read without even footnotes.
Now someone please lock this thread.

[TurboFC3C]

lol, for real. 500+HP is ridiculous.

That white S14 used to have 1000 hp before he switched to this bigger turbo.

Overkill.

[gsxr1]

well i dont post here much but i do have some knowledge and some input on this debate.......

rb25det vs 2jzgte i would pick the 2jzgte for the following reasons

the 2jzgte is better for all out power and reliability....the stock short block record is around 1175 wheel horsepower and that lasted around 6 months of beating on it almost everyday.The 2jzgte currently has a better aftmarket then the rb25det so parts are easier to come by but since its a supra they are also a lot more money in my opinion at least......

also do not mate the NA tranny to the turbo motor unless less then 350 wheel is the target they physically cant take it and will blow........

the rb25det is a great motor and have decent aftermarket but you gotta pay to get the parts since few vendors stock the parts regularly....the current stock block record for this motor that i have heard of in the USA is 575 wheel....im sure theres someone else with higher or maybe not just from what i heard....this is not including the other parts of the world where japan, ausie land, and the uk prolly have numbers up around 700 wheel on the stock bottem end.....

so heres my opinion(and its just my opinion)
if you have the money and want to go all out then i say 2jzgte....why? awesome motor, good aftermarket, reliability, pretty much a very awesome swap in any 240sx or anything for that matter.....

but

if your on a budget then i say rb25det...why? wont break the bank and if modded right can easily handle 500 wheel also for the price of the getrag tranny for the 2jzgte you can do the whole swap of the rb25det into the s13

as always it all depends on the the tuning and how you take care of the car after you have xxxxx wheel horsepower....oil changes are more frequent along with fluid changes, plugs, ect ect to maintain the car your putting xxxx wheel horsepower through...

the stories of"my engine failed at this wheel horsepower" or "no way you'll never get that much out of that motor" are pure bologna... just because they say it cant be done doesnt mean it cant be....they just had bad tuning or something went on the engine that took it out that could have been prevented ect ect.....

read the RB FAQ, there are at least 2 RB writeups on this site, Dave's kit is easy to drop in, don't blow your Fuel pump, presssure test the cyl and go.

[wootwoot]

RB's have failed at 240 hp. STFU you are not arguing a good point.

[eh?]

RB's have failed at 240 hp. STFU you are not arguing a good point.

You have to be retarded if your RB25 failed with less than stock HP.
:gives:

[jaymelz324]

I do not agree with this either. I think the 25 is an awesome motor and will not fail at 240hp but i still feel the jz can handle more.. I do think this debate is over

[mr_240sx]

dude ive seen sr's fail at 200hp so dont start on that.:blah:

[wootwoot]

Why??? Its stupid to have a stock motor fail? Motors fail at all levels of HP. Saying all RB's will last to 500hp is stupid. Some will be able to make far more then that, and others far far less. It depends who has the car, who has tuned it, what they are using to tune it, how it has been maintained. There are sooo many variables all of it. I remember seeing a 600whp stock block ABA VW motor which is a 8v sohc. The most impressive thing about that motor is that its crossflow so in other words it aint shit. Yet, some guys blow those motors at 200whp when they dont do it right. Give it up, you're being a joker. Several KA24's have seen 400-500whp completely stock. They just tuned it very very well.

[eh?]

It's one thing to fail because of poor tuning, poor maintenance, etc.
It's another to fail because the design of the motor just won't take it.

Trying to use the arguement that RB25's won't push 500whp because some poorly tuned/poorly maintaned RB25 failed at 240HP is utterly stupid.
Obviously not all RB25's won't make 500whp. The design of the RB25 allows it to make it there if everything is in order.

500whp KA-T? I've heard of them. How many KA-T's have snapped rods? Now how many RB25's have snapped rods? I've never EVER heard of one.

[wootwoot]

You are acting like these are godly motors. There is nothing that special about the rb25. Does that mean that the design of a KA and of an ABA allows it to make 500whp? Its been done with stock motors.
How many rb25's are in the united states compared to kat's? How many people are to cheap to properly tune a KA-T thus breaking stuff because of detonation? There are gurranteed hundreds of rb25's twisting rods. Just as there are of almost any motor if someone is pushing it hard!!!! Snapping a rod in any motor is straight up odd. Major rod failure all start with a twist which is why I'm leaving it at that.

[eh?]

RB's have a superior rod stroke ratio to the KA-T.
Hundred's of RB rod failures? Show me even one forum thread- US or Australian where one has snapped.
Do you really think RB's are not designed better than KA's?
I think that says enough about your knowledge and yes we should leave it at that.

[wootwoot]

I think you need to quit trying to attack people when you have poor arguments. I know the RB25 is stronger then a KA, how are you arguing it though?....Very very shittily. People have had reliable 500whp-600whp on vq30's with vq35 heads to lower compression. Does that mean they are stronger then RB25's?..People are putting turbo kits on Honda FIT's and running 1 bar on the stock motor making the same hp per liter a 500hp RB25 would be making. Does that make them stronger then RB25's?.....

[SSC299]

I would go 2jz. I'm not to sure, however, about the NA tranny from the supra. I know the getrag 6 speed is VERY strong but I'm not too sure about the NA 5 speed. I haven't even looked into this swap. Is the modification need for the 6 speed to fit really that much greater than the 5?

[jaymelz324]

2jz all the way!!! but yes the rb will b cheaper than a 2j...And the Ka is an awesome motor also, it shows the sr up in just about every category exceptt high end, high rpm hp. Im probably just gonna go ka-t cuz its cheap, and i can fully build the motor for peanuts and have a 500 hp 500tq montster for about a couple grand less than an rb putting out the same and it will b more reliable

[LB.Motoring]

why arguee anymore, I dont even think the pipedream kid is even posting on here, I doubt your gonnna even touch a RB or a 2J, so just stopp bumping this retarded thread, There both good in their own ways. Cheap vs Power, etc. etc.
THE END.

but then again, my opinion prob doesnt matter to you kids.

in the garage, heres austin hypertek moving shit around

..... yah theres a rb25, rb26, and a 2JZ in that pic....

cool picture dude. :gives:

[FastAssS13]

Take it from someone who has both an s13 with an RB25 and an s14 with a 2JZ. Do the 2J all the way!!

RB25s and a pain in the ass to work on and not as much potential I don't think. 2Js are more reliable and a whole lot more fun to drive with the torque. If you have any questions let me know.

[FastAssS13]

And the Tranny I run is the R154 from the MKIII supras. Problem solved for everyone!!!

[tech2drew]

I'm going to have to say 2jz all the way...... 2jzswap.com

there was a guy on here or Nico, his name is Jazz, but i can't remember his screen name, he had a RB25, if I can remember right, he was running stock internals and got somewhere around 575whp, something happend with his PT67 turbo and he sent it back(warrenty) and when he got it back he sold the new turbo,HKS manifold, abd wastegate to me, here is a vid of him running a single T66 turbo supra and a KB cobra

http://video.google.com/videoplay?docid=-538451215272341637&q=rb25

I will be building mine up to 500+ hp, right now I working on the body, when thats done, then the rebuild, right now I'm making 300whp.(stock turbo)

you can put a LT1, 2jz,302,ect....I like the idea of keeping it in the family, thats why I picked the RB25.

Cool vid sky, personally I think you guys are wasting time on this debate. All that was needed to be stated got stated in the first two pages. In fact I wrote it!! hahahahaha seriously though guys your beating a dead horse here.
Fact one. We all Know the 2JZE rocks!!
Fact two: We all know the 2JZE is not a swap thats going to be done on any kind of low to medium budget i.e. its a high ticket swap period!
Fact three: Some people prefer to stick Nissan in Nissan and fact is Nissan happens to have some excellent powerplants.
So in other words unless you suffer from extreme egotism, i.e. I have to be terminally unique and better than, you don't need to step out of the Nissan product line.
Fact four: As is proven above RB25's have a quite a bit of potential. Now mind you, in my IMHO, which I stated earlier in this thread for those of you that took the time to read." If your looking to go over 400-450 HP then you might as well do the RB26". It will cost the same as upgrading the 25 to do it and it will have more overall potential.
Fact five: At this point in time this thread has turned into a useless wank with no relative info beyond bragging rights and bravado at best.
MODS I IMPLORE please lock this thread now .
