RB24DET Stroker Help

[Project_RaceBreed]

I am thinking about doing an rb24 stroker, but i cant find alot of information. So I decided to ask all my knowledgable Zilvians. Here is what I do know: Rb26 crank and rods and tomei pistons....
Other than that im clueless so any information will be great.

[blu808]

You are better off just getting a stock rb25 and modding it.

Fyi the rb20det is one of the shittiest motors ever made, and is useless. Throw it away.

Fuck a Rb25 it has the same problem im looking to delete by stroking the 20. I am wanting more low end torque.BTW RB24's Are Known for being built to well over 500rwhp... Keep ur negative opinions to ur self. I DONT GIVE A FUCK ITS MY MONEY AND TIME SO IF I WANNA FUCK WITH THE 20 THEN ILL DO IT.

[codyace]

Sounds like alot of work...


www.ls1tech.com may have some answers?

Um, you're asking for advice. BE prepared for the good with the bad. I'm pretty certain you are not going to get many people supportive of this idea...


And big deal, 500 rwhp? SR20's do that....big deal!

[Project_RaceBreed]

Well thats fine im just tying to get a little info so i can do this. I thought maybe somone has attempted this and could help. Look i got the motor for free,Got a guy that will do all the machining for about 50 bucks, and have alot of free time and want to try somthing That not to many ppl would do. I WOULD RATHER HAVE THE RB20 THAN A KA......

Free engine? Great - Sell it on here

Machining for 50 dollars - I've had CNC brackets made for more than that...odd!

If you have a lot of free time, why not use the above link I gave you and go from there. Check out the hybrid sections for LS1 swaps...

I'd rather have the KA myself for the daily....

[Project_RaceBreed]

Got a freind thats doing the machining...Not interest in a V8 swap, other than the VH45....I might sell the motor i might not... If i do im gonna get an RB30 block and rb25 head and make a RB30DET hybrid. But i want to build the 20 just to do it....Hell ill build it then sell it....

[blu808]

You might want to consider selling the motor. By the time you finish your build it should be well over the cost of a stock rb25det and take alot of time and sourcing.

Not worth it in my opinion.

As for the rb30. That would be really cool and unique but only if you go all out and build everything correctly. It would be a shame to see another hacked together hybrid engine build.

[steve shadows]

why.....

26 or sr20

thats is all

I mean there was that guy in germany who had his own penis cut off cooked and fed to him before he was murdered.

thats kind of like what your going to be putting yourself through

piece of cake

[Project_RaceBreed]

Just got off the phone with JGY customs, they told me they could do it and rework the whole motor for 5500$. They said that the 2.4L stroker puts down around 340 Crank power and 300 lbs torque.

PARTS NEEDED FOR THOSE RATINGS
Tomei pistons
RB26dett rods and Crank
Z32 maf-(got it)
RB26 N1 Oil pump/Waterpump
Walboro 255lph FP-(got it)
550cc injectors-(got 800ccs)
Cosmetic HeadGasket
And some minor machine work

But i told them to do cams and gears too.

[steve shadows]

oh jesus not jgy

just get a 25 what the hell is wrong with you

Lawl, I heard about that. Crazy stuff.. btw.. I agree.

[hybrid_eg]

Lawl, I heard about that. Crazy stuff.. btw.. I agree.

hahah $5500 so not worth it, plus all those parts? For those weak sauce numbers? Like everyone said you are better of going 20, upgrading turbo/fuel.. internals if you have some extra $$.. and it will still be cheaper then your JGY idea above with waaay more power.. might want to think about it..

[Andrew Bohan]

hey it's his project.

if he wants to be a retard and sacrafice awesomeness to get a little uniquiness, let him

[xblack240x]

LOL love the post blu808 :rofl:

Anyways to the OP... Go ahead and do as you wish, keep us updated, but be prepared for love and hate...

[GSXRJJordan]

*sigh* if you've got a fully functional RB20DET right now, keep it stock, or sell it. I love how you think the RB25 has no low end torque, "like the RB20"... ITS GOT 25% MORE displacement! Have you driven an RB25'd car? Instant power, everywhere.

Look into your RB24 hack job if you want, but keep a price tally. Please, for us, weigh that against a stock-block RB25, top mount manifold, and GT3071 .63 setup.

[CoasTek240]

smokin crack, and smokin crack 2... lmfao....

[soon2bs13]

hey man...where in TN are u?

[steve shadows]

interesting ^^^^^^^^^^^^andrew

[daryl337]

in all actuallity, I appreciate people doing things for originality, but if you are trying to accomplish numbers, it makes sense to go with a set up that has been proven to be better.

Granted rb26 swaps arent the cheapest themselves, you could sell the 20, and use the extra money you have to go for it. I personally prefer SR's because I dislike any engine that is bein driven by a timing belt, not a chain.

Is this opinion warranted? Not entirely. Belts are more prone to breaking, but chains do stretch if not serviced which can end up with un-desired results...

However, I like the timing chain format over the timing belt format, and for the cost... you can easily get an SR to produce the numbers you are seeking...



As far as uniqueness, I know a gentleman who happens to have an SR20VeT set up, which is quite sweet...

There is some modification required, and it is an expensive set up to work with because you need both a RWD SR20det and a sr20ve to properly do the frankenstein conversion, but I was fairly impressed with the job he had.

Basically, it is an det lower end with a ve head... add some machining to the crank snub so the new balancer fits for all of the add ons.. and you have yourself a Sr20VET...

[steve shadows]

^ I just like the SR because it's light, sets more wieght centered back against the firewall and behind the front hubs...

you can't do this with an RB.

UNLESS

you cut the firewall back-ive seen 1 car like that.

I save a couple hundred pounds with the SR and make 500hp, it will be faster than a 500 hp RB car and will also handle better around a road course because the corner balancing will be easer to manage and will be lighter on its toes.

I really don't get the RB craze. If the sr is tuned rigth you can have gobs of torque even witha semi-peaky turbo.

I guess its easier to spool turbos for drifting I have no Idea.

[s13coupedrfter]

oh jesus not jgy

just get a 25 what the hell is wrong with you

LOL I love my rb25...it kicks my buddies rb20 hatch all day! Steve...your argument about nose weight/balance is correct, however the rb in s chassis feels good, it's not as bad as people think it is. Almost half the weight is in the tranny which is half way down the car. With the right footwork tweaks you can have a neutral handling car.

Another benefit to rb swaps is the tranny. sr20 trannys are weak.

I don't understand why not go rb26, 5500 for a stroked rb20. It's cool that you want to do something different but the cost doesn't seem to justify the result. G/L

[steve shadows]

the sr tranny is weak thing is fucking myth

i beat the shit out of mine at 440whp

im still going to go with a dog box/ or straight cut gears.

but the sr box is fine to 450whp all day long if you know how to drive stick properly

but hey to each his own

next time let me tune your SR, you wont need an RB ;)

^ oh and yeah thats my ponint-just go 26 hes almost there will all the damn work he wants to put into a 20 to make it a 24...such a wierdo

+1 for that comment.

I would actually give you +1 if I could, but it says I have to spread the love first... so I owe you one. :)

[Project_RaceBreed]

I'll keep you posted on the progress. Thanks for the help, to the few of u that do support this, Or understand why i am doing it. And to the rest of u, Thanks because now i want to do it even MORE!!!:fawkd:

Exactly. No need to slam gears in a turbo car. Smooth = fast.

LOL. I'm with you on the 'why rb' train....neat engines, good power, but without the AWD, it almost looses some appeal.

I like how ole Shadowerks thinks these days.

[MELLO*SOS]

Man I'm so fucking tired of this. Every forum I go to anytime there is an RB/S13 mentioned it turns into some gay hate fest, usually from the SR owners. This is the tech section, not the off topic, you'd expect at least the premies to respect this? Who gives a fuck what some guy wants to do? Are you going to judge his tire choice next? What about his music choice? Or his favorite food maybe?

To the OP good luck on your RB24, it's been done before just do your research on SAU, SDU, RaceBred and Nico.. Zilvia isn't the best for RB tech.

[usdm180sx]

I am thinking about doing an rb24 stroker, but i cant find alot of information. So I decided to ask all my knowledgable Zilvians. Here is what I do know: Rb26 crank and rods and tomei pistons....
Other than that im clueless so any information will be great.

It's an interesting idea, but not too many people are interested in it because there are more efficient setups available that are tried and true (And also offer more bang for the buck)

As long as you are happy with it is all that matters. But don't expect a lot of people to be impressed as you have seen from the opinions posted in this thread.

[shahee1]

Hey Racebread ... I shot you a note a while back ... its not much work at all ... I have an RB24 that is waiting to get dropped in ... the cost it going to depend on how you want to build the motor. You only need rod/crank from RB26 and toyota 4agze pistons ... in stock form no aftermarket forge you can make over 500HP easy ... Don't worry about the pistons cause they have very nice ring lands (made to withstand high-revving supercharged apps) and are heat coated ... My motor was built at Jim Justice racing in Frederick MD ... He knows a lot about import motors ... he has a looooong resume ... Not to mention he would beat $5,500 easy ... LOL ... my motor was not even close to that. Bore Block/Grind some material away for crank/Clearence bottom of cylinder for rod large end clearence/Increase combustion chamber on head ... this was most of cost ...

If you bought an RB25/RB26 you'd have to look into a rebuild or maintenance before dropping it in anyway ... so you are talking $3,500 - $5K on the motor and another $1 - $2k rebuild (I am being nice on that figure) ... lol ... wow ... I got my extra rb20 for $100 ... it was supposed to be seized ... not even ... LOL ... then RB26 Crank and Rods for $250 ... spun bearing ... nothing was wrong after it was tested. I bought 10 toyota pistons for $150 ... two were new ... So my Kit was roughly $500 without shipping. New N1 oil pump/N1 Water Pump ... Bearings all new, all mew valve train parts, Another $1k ...

So for less than a RB25 clip you will have a fresh motor with the capability to rev like an RB20 (if you work the valve train a bit) and reliable power of an RB26 ...

Do it ... you won't regret ... I'm not ... Give Jim a call.

[eh?]

Sad but true Nico is better than Zilvia for RB info. Bunch of drifting fags here.

[Illestdrift]

lol bunch of drifting fags? at least we're actually using our motors, suspension, and talents... unlike you people who have 300+ hp to daily drive on the streets just so that you can drive 5mph over the limit because you're so scared to "abuse" your car

[Gjohnson7]

Bunch of drifting fags here.

Come on guys. Haven't we learned anything from the cast of Grey's Anatomy???

Can't we all just get a long?????

x2

gl man, i look at it from a cost standpoint as a fully built ka-t (upgraded turbo, aftermarket manifold/ internal work). sure it's a little more expensive but you'll no doubt have a better curve than an sr.

can't remember if you said or not but i'd atleast upgrade to the 25 gearbox, the 20's are not the best.

also, seen you on tennspeed.. slow40 = me

[s13coupedrfter]

It's funny how so many people express opinions without ever doing what they said they know so much about. I like the idea of rb20 stroked, I hope it works out for you racebreed. At least your one of the few willing to DO instead of running your mouth.

See All This^^^^^^^^ Thats all i wanted from the start of this Thread some info on getting this done. Great info this will help out ALOT. Looking fo all the parts specified now thanks.

RB24E SOHC motor = RB24E is a high compression motor.

very few in japan but there are boat loads of them in Austraila. the best trick with your RB20 motor is use a NEO VVL head + find an RB24E SOHC motor in japan. this these 2 combos will be a very nice one, you will need to get different pistons as the RB24E motor is a very high comprssion motor from the newer ones, if any one wants to make an awasome NA project

RB25DD NEO VVL motor swap the RB26DETT head to the NEO bottom end. the stud hole for head will need a little modificaion and then you will have an Autec RB26DE motor.
