Hi everyone... I know that people have swapped the supra engine into the RX-7, but I'm wondering if it can be done under 10 grand. If it can or even if it can't be what parts are needed to make this swap. This includes changing the transmission also.

Thanks

 

Call SP engineering they did this swap on thier car. I don't know the number for them. Maybe somebody else can help or you can search.

 

10k , hell know the motor might cost you that. It would be very very expensive.. It bigger than a 20b and most poeple charge around 30-40k to do the swap(3-rotor) You have to get the supra trany to.

 

why in the world do a supra engine when a V-8 will give you more reliblity, more torque, just as much hp.

sure supra engines can handle boost but you know what, **** boost when you can get the same amount of HP and tons more torque for the same price!!!

 

why hell yes brotha, why not just get a 72 firebird and wheee doggy we can have a good ole time with our big ole' V8

maybe some of us like the feel of turbos...get off your V8 high horse

 

hmm, sorry...i get emotional when people destroy the very thing that makes our cars special

 

Hey, why not put a Porsche engine in there?

Please don't bastardize a PERFECTLY good car. A car that is STILL better performing than 90% of the crap that is coming out this year.

 

I'm saying if he is gonna do an engine swap, must as well go with something which is cheaper, proven, more powerful, more relible, and probally lighter!

 

whoa whoa whoa, destroying the very thing that makes "OUR" car special? Who's car is "our" car? If someone wants to engine swap, you should not feel bad about it, after all its not your car, you did not pay for it. Secondly, there are plenty more FD's out there. If 10 guys do engine swaps (which seems to be the amount of people that have done swaps with other then rotaries) its not gonna really hurt the 10-15k other cars other there. Sure they are getting kinda rare but there will always be at least 1 FD out there with a rotary engine in it . What really gets to me is the amount of people crashing their cars and sending them to the wreckers!

 

i'm fine with wrecking them out, makes mine more unusual, but i don't want our cars to turn into the supras...every supra i see is either N/A or single turbo

 

Q: How could you put a supra engine in an rx7?
A: Who Cares!!

 

Q: Would I be able to put a supra engine in an rx7?
A: Who Cares!! Keep it real, keep it rotary!

 

10k for engine and tranny alone? Im not planning to buy everything new. I might be able to get an engine and transmission for about 4-6k depending on mileage and condition. Japanese car with a V8 doesnt exactly appeal to me, I like the sound of a BOV and a turbo way too much. Realibility shouldn't be a problem because I've seen Supras with 125,000 miles or more running well over 500 horsepower without any problems. I'll attempt to do it for 10k or maybe a little more maybe like 15k, but I will be saving a lot on labor since I'm planning to do it myself with a friend. I will contancting SP Engineering and see if they have any tips or what parts I will be needing to do this conversion. After all, it should be a fun project to do it might take a while. Hopefully in the end it will pay off. I just want some tips and how to go about this. Not hearing "Keep it rotary, keep it rotary." Only reason I don't want to keep it rotary is because it always breaks down or something happens to it. I believe that in the long run it would just be better to swap a Supra motor in there and not keep rebuilding or replacing rotaries.

 

/yawn.. Everyone and their 'motor swap of the week' posts are starting to get old.

 

skunks are you retarded?

the supra motor isn't proven and reliable?
A v8 can put out the same horsepower as a twin turbo supra motor?

Give me a break there are guys running around on the stock supra block with 900rwhp and EVERYONE with a supra has at least 425 rwhp from doing free mods. They seem to be doing okay now since 1993. v8s suck compared to the TT supra motor.

 

blah blah blah, theres no replacement for displacement
stop flaming eachother and start respecting peoples own individual tastes
heres my oppinion
13B-REW>LS1>2JZ-GTE>SR20DET
do you care? probably not. see?

 

I'm gonna do something different! I'm gonna put a RB26DETT with the AWD fully functional How badass would that be!?

Now how many people would consider that a bastard child? I doubt very many

I came up with the idea Anybody does it before me....... they're copying!!!

 

Proven and relible in a FD. Brian's LS1 is running sub 12 secs n/a with nearly a stock engine in his FD and he just installed it, well relativly newly installed. I have not heard anything good about the supra 7 that the sp-engineering guys did. the only thing I hear about that car is that they cant seem to get it to run right.

BTW: for ever 900rwhp supra running around, there are 2X as much guys with V-8's running over 1500-2000rwhp haha so please dont give me that. Also if you think those are stock blocks, you better read up more!!!

V-8's suck??? I'll see ya in my rear view mirror

 

That would be cool.

 

No it cant.

Please factor in:

1) Engine cost
2) Transmission cost
3) Clutch cost (if a manual transmission)
3a) Interior modification to make the transmission sit in the stock shifter location ... cost
4) Computer system to run the car + wiring cost
5) New power plant frame / alternative method cost
6) New driveshaft / shortened driveshaft cost
7) Subframe cost
8) Motormount cost
9) New hood fabrication / or free if you dont put a hood in the car at all cost
10) New steering rack cost
11) New spindles to remove horrid bumpsteer from new steer rack cost
12) New custom header cost
13) New custom downpipe cost
14) New midpipe cost (unless you get the dp just right)
15) New fuel lines to mate to engine cost
16) New Intercooler cost
17) New radiator cost
18) New fans for cooling cost
19) New PS (if you want to keep it) race/system
20) Custom Intercooler piping cost
21) Various vacuum hoses / line cost
22) Battery relocation cost
23) Any misc stuff in which I may have missed.

I do not intend to sound insulting, but if you have to ask if this conversion could cost $10,000.00 USD or less; many people would agree that you are not capable of doing the conversion yourself regardless of the cost. So:

24) Labor to have some one do it, cost.

Have a good day. Enjoy your stay on the forum.

Just a couple points...
- the supra engine is one of, if not THE, most reliable japanese sports car engines ever made (excluding 4cyls)
- supra engine is capable of over 950 rwhp on stock internals
- you can get a supra front clip for $3500-$5500 usd

Other than the arguments about "bastardizing" the car by putting a piston engine in it, and the cost of the swap involved (over $20,000), then why not put it in?

Obviously anyone considering an I6 is not THAT concerned with the cars handling abilities compared to it's power potential, so forget that being a reason not to.

 

I know for a fact that you couldn't get the swap done for $10k unless you did it yourself (this was already pointed out). On the other hand.....i know that i could do it for $10k. Don't misunderstand me.....i'm saying that I could do it for that......i wouldn't charge that by any means. I wouldn't do it for less than $20k because of the labor involved.

Anyone interested? I've got access to a couple motor's and tranny's right now. I can get them for a very good price Hell.....the RB26DETT that i've been looking at is going for $5000 with everything i need. It only has about 10,000 kilo. on it. That's ECU,wire harness,tranny,mounts,diff,etc........

Another $5000 and endless amounts of labor and i've got a car that'll eat almost anything on the road with one little gulp

Let's see if money permits in the next couple of weeks....if so then it's on like Donkey Kong!

I'd like to point out to some people that getting the 2JZ to accept 900rwhp stock is about a $20k minimum. Also....i'm a little confused about the term "stock". When you lift the head off a car isn't that now modified? I thought that "stock" meant untouched internals. The cams, porting and thicker headgaskets aren't classified as "stock" are they? That's always been such a grey area to me.

Those kind of stories are the ones you read in the magazines and on the internet from the new companies promoting themselves. It's good promotion......but very misleading except for the people that know

 

93BlackFD - Unless you are going to buy all the FD's out there, just quit your whinning!

Why is it so many people complain if someone talks about putting a Non-Rotary engine in the RX7. Yet, there are many people that have converted to Single or Non-Seq and they aren't made out to be evil.

If you believe in keeping the car as Mazda intended, then a Single would also be a No, No.

Personally, I do not care for the Rotary engine at all. I prefer off the line power for around the town fun. No matter what, the Rotary has No Torque down low. As Jim Labreck pointed out, his V8 has more Torque at Idle than a 20B at Peak!

 

By stock internals, yes, I mean the head never lifted off. Stock pistons, rods, cams, valves, bearings, etc.
It's not easy or cheap to make 900 rwhp by any means on a stock internal 2JZ, but it can, and has, been done.

 

For some reason I was under the assumption that we were on a "rotary enthusiast" website...
God!! Where am I ?
