Hey. I have a friend with a 99 Integra LS, and I have a 97 Supra N/A (2JZ-GE). I am about to buy a new engine because I an going to get a twinturbo version of it (2JZ-GTE) because of how strong the stock internals are. My friend and I were thinking about my engine swap and future plans when he asked me if my old engine would be possible to fit into his integra. I know that if it is able to go it, most likely, there will be problems with weigh balance and understeer, but I am wondering if the engine would even fit in the first place. I know a lot of parts will have to be cut and/or removed in the engine bay. Any replies would be great. Thanks.

 

Not worth the money it would cost.

 

Well, I highly doubt u can fit a 6 cylinder engine into an integra engine bay.

But even if u did, you'll have a hell of a time with trying to run a RWD engine in a FWD car

Good luck with your TT swap :thumbup:

 

You must be a master mechanic, my friend, to get what you want done. Good luck !

 

Unless you know of a front wheel drive application for that motor, you won't be able to find a transmission that will work.

 

I've always been intrigued by monster swaps like this... I used to own a 240 DL Volvo... and a lot of people hated the weak, poorly built engines, and would do "monster swaps" like a 5.7L LS1 V8, or a 5.0 Cobra engine. I have pics of both... but I don't think the front end of Honda/Acuras is strong enough to support anything larger than a four. I would love to see a Supra motor in the Integra, but it would take an incredible amount of work. Plus a fantastic amount of money...

If you DO go with it, keep me updated. It would be a one-of-a-kind. I would take some measurements first, and post this under Engine Tech, Hybrids, or try some Supra boards. Good idea, however impossible the execution might be...

 

Thanks a lot guys. My friend is hoping for at least 450hp, which is very possible without forced induction. We are still in the process of finding out every detail of how this will work and also he is drawing up sketches of how the engine will be fitted in the back. because this engine is naturally aspirated, no air is necessary to the turbo side so maybe the engine could be mounted horizontally, like a flat 6, and get a widebody kit for the integ. just a though.

btw, for this project- getting the project done is worth much more than money.

 

The only way you could possibly get it done is with a custom transaxle, and even then I wouldn't give you very good odds.

The Supra is rear wheel drive. Its engine mounts lengthwise which attatches to the transmission, then the driveshaft, then the differential (which is in the rear suspension).

To put the motor into a front wheel drive car would require you to find some sort of transaxle (i.e. a transmission and differential in one unit) because you can't have front wheel drive without a transaxle. Front wheel drive cars (save for a select few) mount their motors sideways.

Nobody has made any sort of transaxle compact enough to stick on an inline six for a front wheel drive application save for Volvo in the S80 and XC90. Those two cars are much wider than an Integra, so you would need an even more compact transaxle than what Volvo produces. You could try to have someone make a custom bell housing on the Volvo transaxle but there's no guarantee you'd have enough room. Widebody kits do not expand the engine bay, they just make the wheel wells larger.

Another idea which I just thought up: the second-generation Acura Legend has a 3.2 liter V6 (not an inline six) that was mounted lengthwise and used a very weird transaxle to route power to the wheels. But now that I think about it a little more, that particular setup routed a driveshaft through the oilpan. You would most definitely not be able to adapt this particular transaxle from a Honda V6 to a Toyota inline six. There is also nowhere near enough room in the Integra engine bay to fit the Legend transmission.

This is not a simple issue of getting some mounts fabbed up and seeing if you can squeeze it in. You would need to have a completely new transaxle engineered from scratch for your application, and even then it probably still wouldn't fit. If by some miracle you manage to get a transaxle made, the car would be so hacked up by the time you fit the drivetrain as to be no longer streetable whatsoever.

Just to make sure you understand:

Your idea is basically impossible.

 

Technical details aside, I'm still not sure if you realize that 450 whp can be achieved with the "dinky" 4 banger sitting in your buddy's LS (via forced induction). Of course if you really want to get 450 whp all-motor, you'll still have a hell of a time clawing the pavement with your two front wheels.

How about an Integra with two engines? B18b driving the front-wheels, and a 2JZ-GE (mounted in the hatch) driving the rear wheels?
