Ive been thinking about doing this swap when I get my rx7 (hopefully soon). I thinking about swapping in a 2JZ-GTE (the supra engine). Don't get me wrong, I really like the rotor engines but it costs a lot to increase the HP to where i want and also to keep them from self detonating. If any one knows information on what I would need to perform this swap (it would be my first swap) I would greatly appreciate it. Also if you have any other ideas of other swaps for great HP increases please post them.
Thanks

 

First- the swap alone is money. I think we are talking $5,000+. Then you have fitment issues. Its too high, you need 6-8 extra inches of hood space.
Also, you act like its hard to get horsepower out of a rotary?
Sounds to me like you need to do some research. a 2JZ engine wouldnt be your best bet.
N/A V8's seem to be the weapon of choice now.

 

Ya I figured that it'd be very hard to do the swap but I just wanted something different I guess. I know its not that hard to get horsepower out of a rotary but if i ever wanted to make 700 to 800+hp (not that i want to right now but maybe latter) it is easier and less expensive to go with 2JZ-GTE in the long run.
thanks

 

errrrr, the 2JZ has been done in the Rex already. If you want 700-800hp, why not in a V8? It is certainly easier to get that kind of power out of an LS1 then the 2JZ. Also, there are (believe it or not) more weight and fitment issues with the straight six then the V8.

$5,000?!?!? Keep dreaming boys. A complete 2JZ-GTE swap, with all stock parts would easily run you $15-20,000. Easy. Call SP Engineering and ask them for a quote on a 2JZ-GTE swap in a FD. With alot of goodies on the motor (i.e. 600-650 bhp) they told me $50,000.

 

How much does the V8 swap cost?

 

Depends on a lot of factors, like if you do the work yourself, and if you use used or new parts. Lots of little things that will add up as well. if you go with an lt1 from a wreck, maybe $8K-$10K. An LS1 ~$12K-$14K

 

Nah, you can get the motor and tranny, with all wiring and accessories, including A/C, the works; for around $3k if you look and you get it local. I found one for $2800.00. Cradle and all the 'parts', driveshaft, etc. maybe 1500-2k. Say 7-9k all said and done, assuming you do the labor, if you don't; around 15k.

I think its obvious that you are having Grand Turismo dreams if you want to put an engine in so you can have 700-800 horsepower. Doing an engine swap is far more complicated and will cost you as much as buying two RX-7's. If you are buying the car, that's one thing. But transforming it is not worth the benefits that having a rebuilt rotary will provide you with, assuming that you are worried about the rotary popping on you in the first place. 700-800hp cars are not very streetable either. The amount of fuel and cost in parts will cost you enough that you shouldn't be worried about an engine popping on you if you have the money to support such projects.

 

Also, if this is your first swap, one with so many fitment issues and other variables isn't really a good idea. I am in the process of swapping out the motor in my friends CRX right now, and there are some minor but annoying problems we are running into. But its a Honda, and a Honda motor going into a Honda. Baby stuff compared to what you are talking about. Why don't you talk to Pettit Racing about a 3 rotor swap if you got so much cash. You'll have all the power you need, and you'll still be able to explode out of corners.

 

I second that if it is your first swap, and actually if you have to ask, and not researching yourself (thus being 'resourceful') you probably shouldn't be doing the swap in the first place. Also, doing a 2JZ is much, much more difficult then a V8 from my research, not only from the cradles that Hinson and Grant's are making, but from the size/fitment and weightstandpoint as well. When my rotary dies I will let ya know

However, I do not agree with the costs of a swap being so high if you are able to do the work yourself. It isn't 15 grand to get an LS1/LT1 into the FD anymore, as their prices (part. the LS!) have dropped greatly. (Due to all the id10t kids and their Camaros I imagine.)

 

You better have some money for this one.

 

The thing that has got me hooked looking at swapping to an LS1 is actually how *cheap* it is overall compared to STAYING STOCK!

Think about it, particularly if you are going to get a single turbo and/or want alot of power. Once you rebuild the engine, replace the clutch; replace the turbos with a single kit, a nice intercooler, ECU, etc etc etc. you are **easily** at 6-8k, which is what the swap is looking to cost. 40 hours or so of work, and you have a nice reliable beast that gets 25+mpg. Ever seen what an LS6 intake and some heads do to an LS1? Power what?

Its LOGICAL.

 

i need more power too...do u think a b16 bomber turbine engine will fit in? ...j/k....dont exclude the rotary so quickly....dont cut corners or try to run insane amounts of boost and the rotary will last u....if u want the 2jz so bad just buy a supra...

 

go with LS1 if you're set on a swap. still very unique, only a few on the road...and gobs of potential power, and even in stock form PLENTY of torque

 

Reliable yes, but an LS1 pushing that kind of power, or even stock with an opened exhaust, getting that kind of gas mileage? Not a chance man, but after you feel that power from the second you push the pedal all the way up to redline, I don't think you'll care.

 

That is certainly true....While a stock or near stock LS will get your 20+ mpg, if you really want lots of power, mpg is last on your list.

I am shooting for a nearly stock LS and will like the fact I *can* run the cheaper gas if neccessary (not that I would ), and get alot further on it. Road trips will no longer be more expensive then flying, as they are now ahhaahah.

If you want a 700HP piston motor definately do a V8. Have you seen the HP curve of a 7-800 HP 2JZ? It is almost nothing until 4500, then it shoots straight up. I would rather have a 400HP rotary, it has a much flatter curve that is actually higher all the way up to that 4500 rpm.

 

Who cares if the power doesn't come in till 4500?? If you have a 5 or 6 speed just keep the rev's up!! My buddy had a supra and power came in more like 3800 rpms. All I know is we dusted every small block chevy around, including a Z06. Yeah they may get us till 40 mph but then pow see ya, we were gone. This was a mostly stock MKIV with a intake exhaust and the boost increased. I used to own a hopped up 350 chevy with all the trimmings and yes the low end tourqe is nice but I'd rather have the 2jzgte. You could always go for a 1jzgte, they are 2.5 liters with a shorter stroke. I've seen them go for $2000 for an entire Chaser front clip!! $15,000, $50,000!!! You guy's are getting ripped!! How the hell could it ever cost that much. I can see $6000.00 and that would be with a Haltech e11. Hey I'm stickin with the rotory for now but in the future I may go 2jzgte or 1jzgte. Easy to get 600+ hp out of them and they last forever. A rotory is nice but a 600+ hp rotory is a time bomb in my opinion. 500 would be all I'd want to take a 2 rotor even with 3mm apaex seals!! Plus think of having a 6 speed supra trans!! the stock RX 5 speed leaves a bit to be desired!!

 

Here is the best kit for a V8 (LS1/LS6) Swap http://www.hinsonsupercars.com/

 

20B anyone?

 

A friend of mine is doing the 2JZ-GTE swap. He's going to later have a site at http://www.supraswap.com/

nothing there NOW but it'll be there someday. It should be pretty badass, but his old 13b-rew made 350rwhp at 9psi but it blew before he got to run the high boost.

In case you were wondering, it blew because a certain reputable shop rushed his car out and left the wastegate actuator line dangling dangerously close to the downpipe. Hit a bump on the highway, line hits downpipe and melts, wastegate closes, boost goes through the roof and BAM! no compression on rear rotor.

 

with the stock LS1 in a Trans Am driven right can get 30-32mpg so in a car that weighs about 600-700lbs lighter it should still get 30 even with the 4.10 compared to an f-body's 3.42. Trans Ams run 13.0-13.5 stock so also stock in an FD also with slightly lower drag number it sould be in the 12.35-12.8 depending on driver.

id get an LS1 if i had the money
