I know some might flame me for this but I was doing some research and the Supra is almost the same size as the Celica, wheelbase is only around 23mm apart and the width hopfully rotor to rotor (still need to get exact measurement) is only 98mm apart. the width wont be much of a problem due to the flare on the rear fenders and length can be overcome by a custom bellhousing that will be required. I got the idea from the Top Secret Supra. I know the Getrag will be a tight fit but it might be possible to do this without cutting the firewall. I'm know most of the parts I need and I know how RWD vehicles are set up so that is covered, I also have a live in welder (uncle) so fab work isn't an issue. Some might think this is highly impractical and they're right but it's a great concept that I will pursue. I'm going to hit up Supra forums and try to get more measurements for the drivetrain, etc. If anyone that can help with research it will be appreciated. Anything will help but I could use shifter placement, 3S-GTE width pully to output shaft and Getrag input shaft length. As I pursue this project I will post what I can and if it bombs at least there will be information for any other brave soul that wants to take this on.

im not gonna flame, but gl... if it goes thru. that'll be totally hott.

ok i'm going to say this IT CAN BE DONE .... just take ur time and do ur home work on everything both the supra and celi ... u'll need alot of custom work .. but still doable... good luck ..

Im waiting on a post from Curt at the Supra Store about the 6 speed. I already know the cost of the Getrag and what is required for it to work I just need top to bottom, width and input to output measurements

The Supra's tranny is pretty big. You will have to cut the firewall. Good luck! I want to see someone complete this project. >>

I would like to see this too, but why not make a rear wheel drive with the 3s-gte, thats should cut back a lot of extra time work engery money fabbing.. just a thought?

I think a rwd celi is a rwd celi.. An the 3s-gte would make a lil more sence.

How do you propose getting the rear wheels to spin from a horizontally mounted motor?

-jgreening+Mar 14, 2005 - 7:10 PM

haha, yes i guess i over looked that.. thinking more use the awd tranny. but NM

I think if you want a rwd car, get one thats stock.

You could use the 3S-GTE coupled with an Altezza tranny. Then you'd have more room, since the 3S-GTE is quite a bit smaller.

supra parts wont work... the motor and trans are just too damn big. you best bet would be to source a rear diff and driveshaft from an alltrac and try to custom mount that

When did I say I would use a 2JZ, good motor but I know its too big.

I am getting the idea for this project from the Top Secret Supra. The biggest problem I think I will have is with mounts. The TS Supra had enough room for a 3SGTE and the radiator to lay flat, so the 3S might fit.

yea i want to do this project eventually good stuff that your goin for it
don't listen to people who say "its too big" "just get a RWD car"

but yea 3sgte altezza tranny and you'll be gravy should be really hot just make sure everything is perfect square >>

What kind of HP and TQ can the Altezza transmission handle. Getrag is 1200HP and the only true failures are age and missed shifts.

-Coomer+Mar 14, 2005 - 6:56 PM

I need to check the slope of the bellhousing to see how much to cut but i've run driveshaft tunnels before and seeing that the Celica already has one I just need to check the feed from the firewall to the tunnel.

As a note im from charlotte and yes I couldnt pass inspection with a set up this wild, but it doesn't take much to get this registered in South Carolina.

I dont think that you will be able to fit the 6 speed trans in without a lot of cutting and banging. Even SC300 guys have a lot of problems getting a getrag to fit, and there car is based on the Supra frame. Maybe try their 5 speed trans. But then again, there is the question Jay brought up. Interesting project, if you do attmept it keep us up to date

man... i was thinking the same, RWD Celica... Well good luck!

I want to see someone actually try this. People say that its impossible or impractical, but really, if you did it, you would be the only one in the world! That right there makes it worth it. Go for it, and good luck!

I really really hate these topics... because 90-99% of the time, the people who start these topics... don't know what it takes and don't have what it takes. Here are some simple ones... What rear end? What rear suspension? What about the steering rack? Engine? Trans? Reinforcement? Subframe? Crossmembers? Wiring?

Many people have already "claimed" to be doing RWD conversions, and many are gonna try and "prove me wrong"... but so far... I'm something like 100%... so you're just another new name on a long list of dreamers... How old are you anyways?

yeah great, but why RWD ?

why not just build yourself a GT-4.......

power from a GS GTE and AWD, far better than a RWD unless you want it for drifting ???????? if you want traction AWD and as it already exists you have all the parts and info you need >>

RWD isn't usless for just drifting?
its a great platform for oh drag tooo dur
AWD 6gc already exists too

this project is about beatting the odds, doing what sumone hasn't b4, having an ORIGINAL piece

and kwanza although i do agree with about 98% of what you say cause it really is good info......that was arogant of you to post.....#1 your not god here there more mechanically indepth people here then you, there are people OLDER/Done this longer/and achieved more then you...your not the only one here who can do projects.....
#2 WTF DO AGE HAVE TO DO WITH ANYTHING
he can be 12 for all we care as long as he tries......
#3 i hope he does it to spite everyone

I agree.....having the only 6gc possibly in the world, with rear wheel drive only, will make toyota clap their hands..........its all about uniquness, and if he said he can do it, i and many others on this forum, would like to see if he can bring it.............just because its unique.

That is why I am doing my homework now. I know what it takes to make RWD and i've take into consideration the amount of work. To answer your questions the rear end will be from the Supra (if my measurements are correct), the suspension will be a wishbone set-up, the steering I haven't tackled yet, the transmission will be a Getrag 6, I can't answer reinforcement since that could be anything, the subframe will be stock but possibly modified to accomidate the mounts and front wishbones, crossmembers will be a typical RWD set-up (basically most RWD unibody cars have the same set-up) wiring will be custom, I mean completely custom (I love wiring). So I am ready to find what it takes and for anyone that is also willing to try this here is a link that might ease some pain http://mkiv.supras.org.nz/specs.htm

darksecret you brave brave man(and if u pull this off you ARE the MAN).... do it.... do it...... DO IT!......

hey you have my support ... if you need any help on the 3sgte ask id love to help out... for the wiring since your going big on the whole setup id suggest a haltech or other EMS... please keep us up to date and let us know what we can help with... dont give up >>

I want everyone to know that I am taking all opinions into consideration and as I stated in my first post I know this is impracticle and it will be more work than it seems worth but if I can produce these results this will definitly be a unique vehicle. I know that this is very possible due to the chassis layout. It will take a while due to the amount of modification required but if someone can stuff a twin turbo iForce V8 with RWD into a 5th Gen then I wont give up.

Yeah, that's a good point...I almost forgot about that car. You may want to look at using the ST205 rear end. Didn't that twin turbo fifth gen. with the V8 use the stock ST185 rear end?

Hey Kwanza im 21 and have built or help build 1 950Hp Blown Chevelle, 1 650Hp All Motor Chevelle, a 400Hp GMC Sierra, and now my next project is this and probably turbocharging a 02 Lancer OZ. I know it sounds like talk but if you give a couple of days I can find pics of all of these. The Chevelles are my uncles and the truck was mine, sold it for this car. I have track slips for the Chevelles somewhere also. I was told the truck has a video but a friend has the tape I haven't seen it but i'll try to find it. Given time I can show some proof.

-Coomer+Mar 15, 2005 - 12:09 PM

I can't remember, I have pics and he mounted it to the sides of the frame so if that set-up worked then mounts might not be as much of a headache. Only thing is the V8 is much wider so the mounts would have to be set lower. I would like to get the dimensions of the 3S from the pully to the output shaft, mainly to see what room I have to work with. If I can set the Getrag far enough forward then I wouldn't have to worry about cutting the firewall. Rear ends are pretty generic as far as design, its the axles and differential that make the biggest difference, U-Joints and axles can easily be made so it's more about what kind of housing will fit the width and the types of diffs that can be used.
