RWD Celica, Swapping Supra drivetrain into Celica Options

[darksecret]

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.

i guess it just depends on how much work you want to put into it, but couldn't you build the alltrac tranny to handle the power, and save yourself a lot more headache, because almost everything would just bolt up

If you don't know how it's done... don't bring it up. Converting an AWD tranny to RWD is not easy and requires a completely custom differential when dealing with transaxles. Might as well build a new tranny while you're at it.

Also... don't even say "bolt up". Bolting up is EASY... getting things to work is HARD. Sh!t... a 3SGTE "bolts up"... but only a VERY small percentage of Celica owners have done the swap. The 4AGE 20V "bolts up"... but only 2 people in the United States has ever swapped the motor into a 6th gen Celica.

I say again... if you don't know what you're talking about... don't bother trying to pass advice from wherever you heard it or read it from.

of course you would have something negative to say, I've never seen a positive post from you. If you hate these topics some much why do you keep reading them. I have a 3sgte from and st205 in my celica and everything did bolt up with no problems, as long as you have all the right parts it is easy. I've done a lot of research on putting the st205 drivetrain in a us celica, I have been seriously considering converting mine to awd for quite a while. Yhe only thing i wasn't sure about was how to convert an awd tranny to rear wheel drive, but I'm sure its a whole lot easier than engineering an entire drivetrain into a car it doesn't belong in
And if you don't think this would be the easiest way to build a rear wheel drive celica, what would?

I keep reading them because I'm curious about experimental ideas... but there's a fine line between experimental ideas, and pure dreaming. Good for you that you have an ST205 3sgte... but in my mind... you've still not yet shown your worth in terms of mechanical knowledge.

Here's some info for you. The AWD tranny is a transaxle design, meaning there is one specially designed AWD diff on a transversely designed tranny. This diff distributes power to both from wheels, and to a driveshaft. To make this ONLY distribute power to the driveshaft... you'll have to build a custom differential. If you know ANYTHING about transaxle differentials, they are very expensive to work on, let alone have a custom built one... because there isn't a real way to lock up that diff. It's harder than installing a getrag 6 speed... which requires some body/chassis work, but I personally think the getrag is overkill anyway.

Now... as for me being negative... if you care to notice, everyone with good mechanical ability and respect around this community has been reluctant say this is an easy "bolt on" job. You can call it negative... I'll call it realistic. The kind of realism that can only be gained from experience with cars. Like I said before... there is no easy way with these projects. Anything mentioned here, including my information, is merely speculation because this sort of project has NEVER been done. In other words, our opinions are pretty much worthless to a really serious person.

In all honesty now... if anyone were to complete a project like this, I'd least expect it to be done by a relatively new person. I know if I were to do anything like this, I'd just one day post pictures once everything is said and done.

Converting a awd transaxle to rwd isn't dreaming a lot of people have done it, it's not something i just came up with out of nowhere. I just like the idea of using all parts that where meant to be on the car, but I never said anything about this being a bolt on job. I'm very aware that there would be a lot of customization and problem solving. What I meant was that a lot of the main components would bolt on with out major modification. If I thought this was an easy bolt on job I would have done it a long time ago. Dreaming to me is the idea of building a tubular frame around the rear end and get c/f body panels molded to look like a celica. Reality is finding a jdm gt4, having it cut in half, bring the front on one boat and the back on another, and transfering the gt4 drivetrain to my car. And if dragging the transaxle to a shop that could convert it is expensive so be it. At least I would have a car which was almost completely engineered by toyota. In the long run I think it would be worth it, even I f it did cost a little more.
