Favorite engine swap and why thread

[240boi115]

Ive looked around and couldnt find one but im just curious as to if there is a thread on what engine swap is prefered and why by the members on here....:-/since i hear so many people shit talk on other motors why not start a thread where numbers, power gains, bang for buck, daily ability, ect. are put into play. And no lets not let it turn into the typical KA vs SR thread either, im talking about everything from the ls, rb, sr, ka, ca, vg, vh, vq, 7m and ect...

Im also curious to see how far this thread can go without everyone wanting to jump through a computer and bash one anothers face in.:picardfp:

[240boi115]

so i say no shit talking and this thread dies....lol

[idahotuner]

looks dead

[Young Sileighty Kev]

sr20 the only reason why is because this is my first 240 and a lot of people say its a straight forward swap. and also its pretty cheap compared to the other engines i wish i could have.

[simmode1]

I'm tired of swaps and NA-T projects. My next toy will be factory turbo'd. Probably VG30ET.

[g00se]

Are you talking about only 240's?

LS1 into my S14 (improves gas mileage ~28-30 mpg, quadruples hp, sounds awesome)

2jz Aristo engine and Auto tranny into my Volvo 240 (working on fitting the shifter)

SRT4 engine mated to my 1992 Caravan (12 second tow beast)

[13esim]

VG30DETT is a nice swap for a S chassis, especially for people in CA, it has good power to start off with and will pass smog LEGALLY

[240boi115]

it doesnt have to be a 240 but since this site has a majority of 240 owners id expect some imputs on swapped engines into them....bang for buck id have to say the ls1... if you get all the fabricating right to get all your gauges to work it provides lots of power and good gas milaged... you can also burn rubber for days with no issues of blowing up a turbo...

im thinking of going KA-T in my hatch though and want to see if i can do a smart and cost efficiant build... NOT CHEAP JUST GOOD PRICING ON GOOD QUALITY PARTS.

[240boi115]

im also curious to see what motors have been used to attain peoples goals for power and realiability...to be honest id like some light shed on the motors that dont get talked about as often as the SR,KA and RB this could help others...

[13esim]

Im considering going with a 2JZ in my Z32, reliable, powerful and decent pricing on parts due to the large aftermarket following of the supra and other vehicles using JZ's. Oh and they sound great.

[240boi115]

i saw one of those before... your going to need some pretty low motor mounts and a new hood... lol the motor wont clear the oem hood.

I'm pretty much resolved that I'll never spend money financing a swap when there are already good motors with good chassis' built around them readily available.

BUT!

If I were gonna spend money on an S-chassis swap, the little talked about VQ30DET would be my easy choice. Weighs just a tiny bit more than an SR20DET, makes RB25/26-like power but with more torque, can mate to 350Z 6spd trans and its racebred technology that replaced the RB series in the old JGTC series. Whats not to love? The fact that its easier to wire up than any VQ35 is just icing on the cake.

SR20DET.

Cheap, can be built to JDM spec for reliable, fun daily driving... or for 700+hp extreme performance and anything/everything in between. Lightweight aluminum block- Insane aftermarket support; straightforward, plug & play (w/harness service) swap as stated above... and very maintenance-friendly to boot.

However, even though I love them, SR's will NEVER look/sound/feel remotely as awesome as RB's or JZ's

** If I ever do another S-chassis, there will be an RB26 making the power- period.

[OrangeVirus1]

RB20DET

#1 reason is because everyone hates the shit out of it

[A DUDE]

SR vs RB vs 2J hmmm decisions decisions haha

[az_240]

Aluminum Chevy LS engines. Lighter than those turbo straight six iron block engines, tons of torque/awesome power band, decently good on gas, smog legal, simple, looks nice, sounds good, and don't have to build internals to be reliable while making good power.

The 2JZ would be my second choice.... but only if moved waay back into the firewall.

[driftracerx]

rb26 because id rather keep the Japanese muscle alive

[trxrx7]

if i would be doing a swap it would be something unique that not every other guy has(lsx, 2jz/1jz, rb's). and that would be a bmw e46 m3 motor, comes stock with ITB's and 340hp slap a turbo on it and you will have a very powerful and sickest sounding motor in a 240sx, plus the germans really make quality stuff

[Akiros]

I'm kinda suprised that no one has mentioned the 1uz yet. Mounts can be had off of ebay AND it's pretty much the most reliable motor ever. The non vvt one makes about as much power as a bolton SR and the vvt one dynos almost 300whp with boltons. Or you could just swap in a turbo m3 motor like the guy above me suggested.

[The Dude]

Who says you get good gas mileage with an ls swap? Definitely not the case if you keep the stock 4.08 FD.

1JZ / 2JZ
I just love it.
Lots of Torque and Power.
Motor is very reliable and can take a bullet. friend had a 1JZ at 700hp with stock internals and bolt ons and a big boy turbo
Costs around the same as a screaming V8 with just as much power.
The sound is well, A DAMN SCREAMING GORILLA FILLED WITH AWESOMENSS.
And well, who doesn't like a reliable turbo motor. Only downfall is the weight. It does weigh about 200lbs more than a V8, but honestly that is not that big of a deal to me.
Even though I am building my car for competition, whats 200lbs to be a little different than the next guy. :D

this is in regards to a USDM 2jz

Not only is it a proven motor, but because it was offered stateside makes it a hell of alot easier to get parts. Plus if done right, you have the option of getting it bar'd and not have to worry about smogs or getting reffed.

1000 hp on stock gte internals, other than arp studs and thicker hg... yea tell me another motor that can handle that.

yeah.. tuners in japan kept frying ecu's trying to tune it when the car first came out. the computer running the car is literally too smart for its owngood when it comes to tuning. xD so i feel you there i wouldnt dare crack one of these open unless i was absolutley sure about what i was doing:eek:

[Kingtal0n]

engine size/manufacturer has little to do with fuel economy. It mostly comes down to vehicle weight, rolling resistance, and rotating mass (assuming we are talking about sequential fuel injection and proper tuning). The 2j has a fair amount of rotating mass AND engine weight, so usually swaps in a 240sx end up around 3200lbs and with an automatic trans net about 25mpg. with a six speed it gets a little bit better. and with some lightweight rotating components such as alumnium rods and lightweight flywheel/driveshaft etc... it gets better and better.

But the same applies to say... an LSx engine. You can also get 25mpg out of that in the 240sx chassis... mainly for the same reason- final vehicle weight is around 3200lbs.

It all adds up, Look at an SR20DET that nets 30mpg such as the s15 six speed swap. The low rotating mass (compared to the automatic transmission) and numerically low gearing (3.4x at the rear differential) help keep the energy lost to turning the internals of the sr20det low. In other words, it takes X horsepower to push a 3000lb car the same distance no matter what (forget wind resistance). Now as you reduce engine RPM, you reduce energy lost due to turning components. So as we lower and lower the cruise RPM of that 3000lb vehicle we use less and less fuel to go the same distance. Thats because you have to first calculate the HP required to move that 3000lb vehicle- and THEN add the HP required to turn every single drivetrain component at a given RPM. That cost decreases as RPM decreases, generally. but the cost to push the car remains the same.

[240boi115]

feels like i just studied some physics xD makes sense LSx motors give good power to weight ratio and with good light bolt ons can get pretty good mpgs..
hahaha come to think of it ive heard plenty of people state why theie rear seats and interior is gone and the answer includes gas milage.

this also explains why i am usually pro sr20 because its weight to power ratio a long with its mpg fit a good dd/weekend track car:naughtyd:

Thats funny I took out my rear upper seat and spare tire for increased MPG. I At one point I had a 5-speed sr20det S14 with a PFC dialed in at 42* BTDC for a 3400rpm cruise at 74MPH. I was getting around 440miles per tank of gas, around 13 or 14 gallons. I have a video somewhere maybe I can dig it up. The trick was setting the wideband narrowband output such that 15.3:1 was around .004Volts and 14.6:1 is about 0.996 volts- so it cruised about 15.1:1 air fuel ratio. You could see in the video this happening. It must be in my DVD backup. well I will pull it up if there are demands to see it otherwise too much work.

[240boi115]

haha no demands bro i believe you but ive done the same thing taken all my rear components out for mpg.. strangely though my s13 sr blacktop was getting around 400 miles to the tank with everything still on the vehicle..0.0)/) then again i did a whole look around and fluid change as well as gasket replacement on the engine before even starting it up.. what boost were you running? stock 7psi?

no that car had about 380 legit rwhp. I got the engine with forged internals through a trade, it already had a top mount 60-1 on an ugly t3 top mount. I changed out the 60-1 compressor for a 50 trim, T04E, and of course I lost about 20 horses up top (from 400->380) but it spooled much faster and was much more fun to drive. I have a dyno of that actually available I can grab without effort

^^^would that end up being your fav swap? and why so interested? looking to get one? just curious..

It sounds very promising. From what I've read, it combines SR-like weight dist, v8-like response and torque, and 6 cyl sound. Plus, since it's not a well known swap, the drifters haven't trashed all the good condition motors yet.

My favorite swap is a plain ol' sr20, but the vq30 has my attention.

so youd be taking one from a nissan Gloria or leopard? there are soooo many vq motors!!! 3 of which were in jgtc cars..

[Kingtal0n]

I avoid V6 configurations. Mainly because you get all of the hassles of a V8 (two heads, two exhaust manifolds/gaskets, two sets of head hardware, two sides of stuff to fail basically) plus they are much harder to work on (change the plugs on a V8 and youll see what I mean)

And at the end of the day you dont even get V8 displacement. You may as well go V8. I see Inline 6, or V8, as viable options. The Inline 6 is a all of the torque and response of the V6 (there is nothing magical about a V configuration) with the added benefits of having only 1 single head gasket, 1 single exhaust manifold, etc... a much simpler design, and easy plug access. Easier to work on.

[Kingtal0n]

heres an oem internals 2j I tuned with an upgraded turbo, injectors, exhaust, and power FC. Around 15psi of boost on pump gas. I didnt choose the turbo size I feel it was mismatched, but I am just the tuner for this one doing my job for paid.

anyways. The First run (blue) is the proper ignition timing. The red line is when you add 2* of ignition timing past optimal. The green is -2* of ignition timing.

Notice when you add +2* of timing btdc it gains torque, but loses horsepower.
notice when you pull -2* of timing it loses both torque AND horsepower. (but not as much horsepower)

SO there is an optimal point, and it is +/- 2* btdc

http://i23.photobucket.com/albums/b378/draglarry/Recent_tune/P1130296_zps725b0cee.jpg

the "gains" in torque from the red line are not actually gains. They are indicating that there may be (most likely) damaging pressure spikes beginning to occur during combustion, giving rise to slightly inflated torque numbers. But that behavior leads to a blown head gasket, damaged rod bearings, and it can eat up the head and deck, and take small chunks/flakes of the piston apart. Especially being cast components. An experienced tuner could tell by the shape of the torque curve, see how it sort of meanders up and down? Years of experience is why I know this.

You make some great points. But don't forget to consider the one huge critical advantage of the VQ30DET: The fact that it weighs about as much as an SR. Aside from the rediculous torque the VQ30DET makes, the weight savings/distribution might be worth the trouble to some ppl.

I love the idea of the VQ30DET, but these days I'm all about simplicity. So I'll just stick with an S13 or S14 SR mated to a Z33 6spd trans.

[RiskyRick]

Ever owned an lt1? After 2 of them, I don't complain about changing spark plugs in anything.

Being coil on plug w/ the plugs in the middle of the heads, I don't know if this is really a valid point, although I have not changed spark plugs in a vq before and could be dead wrong.

May I pick that idea apart a little? thanks. Not knocking the engine by any means, however,

1. an LsX also weighs about as much as an SR20DET. so any weight saving is moot considering that sole fact. And even more so when you consider the additional power output of the lsx (and torque and everything else).

2. the v configuration engine is not going to sit in the same place as an SR20 unless you make an absolutely perfect set of mounts and do all custom fabrication required for such a thing to be possible. In other words, even if the engine is lighter, it would also need to be located in the same exact spot to take full advantage of its weight saving and "distribution".

each car has a purpose. if you are more concerned with straight line power, reliability, and are on a budget; the 2jz is the obvious winner.
if you want a little less power, same reliability, and want a bit more handling, I would go with the sr20 (for about 200 horsepower less you get a lighter vehicle, better fuel economy, and with OEM suspension at least, better handling). A 2jz 240sx could be made to handle well with a ton of suspension modifications of course. So could a KA24DE 240sx; or any car. But I am into daily drivers with OEM suspension, even oem shocks. and 2jz 240sx, while very fast and fun to drive with 500 horsepower while on a budget, probably would not be as great of a thing to "take corners" with on OEM shocks in a 240sx.

I don't understand your point about having the engine mounted properly... Just do the shit right the first time and mount it as close to the firewall & as low as you can sensibly go. It's not like it hasn't been done before. You'd apply the same logic to a V8 swap as well.

Its the most commonly swaped engine ever! Anybody who has driven one or has sat in the passenger seat of vehicle with this swap will understand why. Small block Chevy. Me my favorite swap would be the vg30dett but I'm kind of biased.

as to the weight, 100lbs is nothing. plus or minus 100lbs is not going to change much as far as power:weight ratio, not like going from a 240->camaro where you gain 1000lbs in dead weight. I would not let 100lbs stop me from adding +2 cylinders and almost 2 more liters of displacement to my chassis no matter what platform. I would LOVE to add 100lbs and gain 2+L are you kidding?
thats a whole extra sr20det engine under the hood for +100lbs!

As to how the engine is mounted, Figure you install that VQ engine in a 240sx and it happens to be the same exact weight as an SR20DET. I guarantee you that it will not be located in the same exact place. that means there will be changes to suspension geometry and handling, and if the weight is more forward or higher in the chassis I have a feeling it will also affect drag launch characteristics among other things. again, application specific stuff. If you are drag racing, nothing a good set of tires might fix. If it's a street car daily driver we probably wouldnt even notice. But the same goes for a 2jz-gte, an extra XXXlbs or whatever, I dont notice that on the street. But I do notice 600 horsepower that didnt eat my wallet.

Just how much do you think it costs to build a 600hp 2JZ swapped 240? If that didn't eat your wallet, congratufuckinglations because that shit is a killer for most ppl.

But I do think you might gain some benefit from reading up on some VQ30DET build threads. You are generalizing a whole lot just for the sake of arguing for the V8's behalf.

Either way, I don't care. I prefer SR + Z33 6spd trans.

Sr20 would be my 1st choice (maybe cause I have one at the moment), if it where to be any thing besides that it would be the 2jz.
Have read a lot of good things about that engine, how reliable it is and how much horsepower you can get out of it. I have few friends with RB engines and they are always fixing some thing on them. RB would not be a choice for me.

Oh and by the way, for those people that love 240's and the whole Jdm thing. You should stick to it! Putting a domestic motor in a 240 is not cool!
If you want an ls1/2 then just buy an American vehicle! Lol

[Kingtal0n]

Just how much do you think it costs to build a 600hp 2JZ swapped 240? If that didn't eat your wallet, congratufuckinglations because that shit is a killer for most ppl.

But I do think you might gain some benefit from reading up on some VQ30DET build threads. You are generalizing a whole lot just for the sake of arguing for the V8's behalf.

$13,500 for that swap including labor.
Thats actually an 800RWHP setup (pump @ 550rwhp, C16 @ 800rwhp)

sold the entire car for $19,000 in 2009 I think.

if you do the swap yourself its around $10,000.
No other swap in existence, even when you do ALL the labor yourself and ALL the welding, will get your 550rwhp, 25mpg, and 200,000 miles of daily driver reliability for that price.

Considering a stock NA 2JZ can't even do 25mpg I'm calling bullshit.

Also a stock $350 LM7 5.3 will push 700hp with an ebay turbo. Proven a dozen times by Hot Rod and Car Craft magazines. Thats a $2, 500 engine build.

People build 550whp LS engines for pocket change*.

And they have also been proven to stay together at over 1000hp on the stock internals by these same magazines. For how long, no one can really say, but the testers claim many, MANY runs at 1000+.

So there's another main 2jz bragging point.

Vh45de in a Z32 because at 3400lbs, 222hp and 16/22mpg NA, I feel like it might as well have had a fuckin V8.

They had the vh45de in 89 made 278hp.......
But imo the TTVG Is a better engine aside from the nightmare to work on. The na z32's are nice as a dd I miss mine at times.

[DS562]

Well don't get me wrong, I love my NA Z32. At times, though, I really feel as if it lacks something...be it 2 turbos or 2 extra cylinders. And at least -300lbs

[DS562]

I HAVE to accomplish my VK45DE/cd009 combo in my Z. Have to have to have to.

I've been doing some research on the whole 1uz swap. Swap is cheap and the tranny opinion area super nice looking.

1uz is an all balance motor was really interesting too me too.

im trying to stay away from forced induction. i know it does wonders for an engine's power output, but i dont want to worry about longevity. there's so much more that can go wrong with a TT'd daily that i dont want to deal with it.

so im assuming you own a 300zx? in which case yes... stay na lol any other car boosted is awesome and easier to work on IMO. i would never boost an 86 though. it jus tfeels wrong to boost an 86:ughd:

[simmode1]

Two other non-Nissan N/A swaps I like are:

2GR-FE powered MR2
J35A3 powered S2000

[240boi115]

what about the f20? 240hp NA powered motor!! those in hatchis are pretty wicked.. gotta love the s2k cluster too.. although working at a dealership ive heard the ap1 differentials are weak/ tempermental.this true?

[Hartshorn_]

I'm in the process of my 1uzfe swap right now. Very straight forward to do. The hardest part is the 1 hour of wiring if you're not comfortable with it. I'm planning on a megasquirt ms3 for future boost capabilities.

You are not going to be swapping rear ends.

If you met mpg, either you ate lying or you have no idea how to calculate mpg.

yep. i have no power steering or AC and dual electric fans its still a bit crowded in there. not nearly as bad as it was straight from the factory... my oil filter is pretty accessible but i think i would sacrifice the space for 2 more cylinders.

Fuel economy has very little to do with the engine you are using. Unless its a horribly mismatched vehicle/engine displacement (1L engine vs 4000lb vehicle or something silly)

In a 2500lb vehicle, any 2.0, 3.0, or even a 6.0L modern EFI engine should be able to put down 28mpg.

engine size/manufacturer has little to do with fuel economy. It mostly comes down to vehicle weight, rolling resistance, and rotating mass (assuming we are talking about sequential fuel injection and proper tuning). The 2j has a fair amount of rotating mass AND engine weight, so usually swaps in a 240sx end up around 3200lbs and with an automatic trans net about 25mpg. with a six speed it gets a little bit better. and with some lightweight rotating components such as alumnium rods and lightweight flywheel/driveshaft etc... it gets better and better.

But the same applies to say... an LSx engine. You can also get 25mpg out of that in the 240sx chassis... mainly for the same reason- final vehicle weight is around 3200lbs.

It all adds up, Look at an SR20DET that nets 30mpg such as the s15 six speed swap. The low rotating mass (compared to the automatic transmission) and numerically low gearing (3.4x at the rear differential) help keep the energy lost to turning the internals of the sr20det low. In other words, it takes X horsepower to push a 3000lb car the same distance no matter what (forget wind resistance). Now as you reduce engine RPM, you reduce energy lost due to turning components. So as we lower and lower the cruise RPM of that 3000lb vehicle we use less and less fuel to go the same distance. Thats because you have to first calculate the HP required to move that 3000lb vehicle- and THEN add the HP required to turn every single drivetrain component at a given RPM. That cost decreases as RPM decreases, generally. but the cost to push the car remains the same.

[Bmxer300zx]

So you're saying a 1985 302 v8 in a miata is going to get the same mpg as a 2jz 240sx? And I wanna know where you get your vehicle weights from because your lsx 240sx is 100lbs lighter than a fucking 4door 1jz cressida.

Did you not read: "modern EFI engine" a 1985 is not a modern EFI engine. V8's from pre-95 era tend to be sloppy and have reduced fuel economy and increased emmisions because of it. once you hit 1995+ especially 1998 era things got much better for V8's.

A 1998 LSx engine in a Miata should do 30+ mpg easily.
And weights are subjective. most 240sx start around 3000lbs, usually less. Sometimes as low as 2600lbs. A 2j only adds a hundred or two or three to that, usually 3200lbs or less is the final weight.
But we can gut and tube it to get it lower.

[itsjustdaphne]

how about a vh45 in a s13????

My brother has VH in his Z32. After swapping in I think 4 of them now, I look at it more of a daily driver v8 swap. Why? Inconsistency at the track. Some say it's the weight of the Zed but there's a Kouki S14 in local events with the same issues. It's easy to swap and most would be happy with the upgrade if they are looking to go V8. For street messing around with a couple of power slides mixed in with the daily drive, it's a great motor.

But anyway,
I personally like the 1jz, and will most likely swap one into my S13 in the future.

:bs: I have a stock Miata and it doesn't get 30mpg.

[Kingtal0n]

:bs: I have a stock Miata and it doesn't get 30mpg.

It needs an LSx drivetrain with six speed to get the 30mpg. My stock 240sx gets 24mpg but with an sr20det @ 400 horsepower I get 30mpg.

furthermore, I bet your OEM engine would put down 30mpg if (choose some):
you refreshed all the oil seals including piston rings in the engine and increased the compression ratio
you reduced the engine RPM on the highway
you fine tuned the engine to cruise around 15.2:1 air fuel ratio
installed high efficiency / highly atomizing fuel injectors with sequential EFI
increased the strength and size and duration of the spark at the plugs (MSD box comes to mind)
reduced rotating mass of components such as flywheel driveshaft wheels accessories
reduced the drag of wind resistance by lowering the vehicle or altering its shape

Lots of things you can do to improve fuel economy. I can think of many more but Ive got to go to class now.

[The Dude]

From experience swapping an LS1/T56 combo into my S14 and also having a KA and RB25 in the same car, the mileage does not go up; it goes down.

[Big Zee]

personally my motor swap of choice, would be a SR20 or 22VET. for a S-Chasis

reasons are
lightweight motor
higher revving still
unique motor still
no broken rocker arm worries
make lots of power for days
clean looking swap that looks like it belongs there.

saving up for it, but for now rocking a redtop SR

No I did read but you also said engine size doesnt have much to do with fuel economy its simple more cyclinders/bigger displacement will use more fuel even at idle with no mass being moved through drivetrain. Now comparing a 6.0 vortec to a old 2jz is dumb you're talking 2 different engines from different times. N2m most people who go to a v8/lsx swap have a tendancy to strip it of ANY economy related componants even such the ecu is retuned so how can it give more mpg after all that than the vehicle rated mpg it came from?
Now if you slap it in miata vs a vette I can understand a bit of a mpg gain but not to where people should be thinking " well if I ls1 my miata I'll get better mpg's than a 2jz in my 240sx cause it's lighter..

Thank you my mx83 with a sr20det had alot more mpg than the pos 7mge and my rebuilt Na z32 did. That's a smaller displacement motor in a car weighing at 3400 lbs before weight reduction.
.
This guy up here claiming a smaller displacement engine in a heavier chassis gets less mpg is making no sense

[Kingtal0n]

From experience swapping an LS1/T56 combo into my S14 and also having a KA and RB25 in the same car, the mileage does not go up; it goes down.

what was the vehicle weight before and after the swap?

because that's what really matters.

And of course, you will need to have data logs of the fuel injector duty cycle, fuel pressure, and compare with road speed in real time to know for sure.

Because an engine like an LS-X will use more fuel if you are not setting cruise control and driving at a steady speed for 100% of your calculations. Accelerating, for instance, can eat up a significant amount of fuel since the engine is capable of producing so much more horsepower.

You are still thinking from the perspective of engines. Physics doesnt care what engine you are using; it takes X amount of horsepower to push a vehicle with a weight of Y. Simple as that, end of story. Keep swapping engines all day and the mileage will be similar as long as the overall efficiency of the engines is similar. A 2j has a very similar efficiency to an Lsx; actually the Lsx should be a little bit better.

Using your example as an engine is idling. Comparing an SR20 with an LSx engine. I agree that the LSx has heavier rotating components, and should use more fuel at idle. But if you actually calculate the horsepower requirement between the two engines rotating, you will find the difference is negligible. that is, the lsx may require more horsepower to turn, but it will also probably idle at a lower RPM which will reduce the horsepower requirement. But that is also negible. What really counts is the fact that both engines require a very minimal amount of horsepower to turn, the difference is probably less than 1horsepower overall between the two. Which means differences in idling fuel requirements will also be negible.

But that is all overlooking the fact that the LSx has a higher compression ratio and therefore extracts MORE horsepower per ounce of fuel burned- therefore, the lSx most likely uses less fuel overall than the SR20 does at idle.

[Bmxer300zx]

therefore, the lSx most likely uses less fuel overall than the SR20 does at idle.

Wow... just fucking wow
