front drive celica to rear wheel - 6G Celicas Forums

Topic #8656 54 posts Started by pyro0694
i was skimming through the forums and saw a topic on converting US spec celicas to all wheel drive using the all-trac drivetrain. i read that the possibility of the conversion working was slim to none. i thought it would be easier to convert it to rear wheel drive using the old jdm corolla(AE86) drivetrain. i was wondering if this was more feasible than all wheel drive.
This is one of those questions that can be answered by saying with enough money anything is possible. The problem people have had with the AWD conversion is getting the rear end on correctly and keeping it alligned, so you'd probably run into similar problems with the AE86 parts also. It would most likely be incredibly expensive to do it correctly, but it would be awesome it see it done. Good luck to you if you want and plan to do it.

BTW, for the AWD conversion to work, you need all the parts from a ST205 chassis, including all the floorpans from it must be swapped in place of the yours. The difficultly of doing the conversion correctly is many times way understated, so be forewarned.
you could also take a plasma-cutter and cut out holes in the floor pan for the rear dif and weld in some bent up sheet metal, so the ST205 floor isnt necessary. actually using the AE86 drivetrain isnt a bad idea, cuz you could probably swap the 4AGZE motor in at the same time and link it to the 86's transmission and drivetrain, but you may need a different sized driveshaft, which inst too difficult to get, you just need to get the correct yolks fitted and balanced.... hmm... you would probably need to cut up some space down the center of the car as well for the driveshaft. the complete rear end would be a full custom job becuase you are switching from a IRS to a solid axle... weld up some new mounts, just gotta be real careful with the alignment. motor setup would be a complete custom job as well since you are switching from a trans. mounted engine to a vert setup. overall not a bad idea, but LOTS of customizing.

id say feasably the AWD swap would probably be a little easier since the motor will still be trans. mounted, and theres already a production car with that setup.

if you do that your better off starting out with stripping the car... and getting to just the frame.. and working up from there... that would make lining everthing up alot simpler...

Hmm...

Silvia
Supra
AE86
MX5
RX7
IS300

All reasonably available cars with RWD that you could get and be very unique and cool with.

the firewall wont have to go. you can bend it up out of the way with a sledgehammer to fit the tranny in underneith the car. and you can also mount it so the motor and tranny sit lower in the engine bay so it actually clears it. the point is if you have the money and know how to do it, you probably can. but yea, its so much easier to buy a car already setup like that... but not everyone wants to take the easy route. >tongue.gif>

then take the same sledge hammer and give the gas tank a couple good wacks.... after thats done...... have a smoke!

the fire wall is just a sheet of metal can be cut after everthing is in... this is was you strip the car and start on the frame... you build around that...

you might want to go in this order
Frame
Supspension
Engine/trasmmisiion
electrical
interior
chasie
body panles

this way stuff like the firewall won't be a problem

[TeamNJCT
the firewall is part of the unibody, i guess you could punch out the spotwelds and remove it, but i really dont think its necessary.

Bolt a tube frame to the floor pans and weld it in everywhere you can find. Bolt all of your major rear end parts to the new frame, and you can cut any part of the floor pan out you need. The tube frame will keep everything straight.

The problem with the RWD set up is getting the speedo to work.

I think all four tires are used on celicas to get the speed, that means you have to deal with the back two sensors. I personally would use the rear wheel bearings and suspension parts of a GT-4 ST-205, I am sure that would be easier to get than the whole rear end.

Out of curiosity, were the early supras I6's?
some one help me out here but isn't the speed sensore located on inside the transmission ???

[TeamNJCT
sorry but i dont think you are correct FallenHero. there is one speed sensor that bolts into the tranny. the reading from that sensor is what tells your speedo how fast you are going.

i think your are thinking of the antilock brakes speed sensors that are located around the wheels. those are just there to determin if one of the wheels is slipping

any changes to the firewall are absolutely illegal

my signature is the coolest.give me your celica.
so are non-DOT altezza taillights. what is your point??

chalk that one up for the haynes repair manual explaining things so well;)

It said speed sensor, I had no clue... But if you have ABS, I suppose it would still be a problem >smile.gif>
What be easier and had a better channce of success?

A celi on a 240SX frame or
celi on corrola frame

Both w/ 3SGTE

If someone seriously wanted to do this they could build a custom frame that will accept all the exterior from a celi.

My friends father races trucks, and they swap turck to unibody for weight reasons.

People who build 1932 ford roadster sdo not even use any parts from the car usually, they just buy it for a title.

Basically it would be the equivalent to a kit car.


Please don't flame me on this, but if you look into hot rod restoring you should be able to find out about this. I think it would be a killer idea. Would be completely original(show aspect), and would become a force to be reckoned with. Only prob is most cars built like this usually take around $70k to build, but it's just a thought.
that's why you bolt a small square tube frame to the floor panels. then you can cut away and not worry about it braking in half >wink.gif>
that is similar to what some of my friend had to do to their G-bodies(monte carlo/cutlass) the fram has a tendency to twist when put under too much stress from motor.

This is getting even closer to turning a celi rw or awd w/o complications.
boxes in the chevy's work so I believe this would work also.

only prob is bottom of car has to be modified to hold a new rearend, right?

what rearend and tranny would be used for rwd?

Old style supra? a corrolla rear end?

what is the lengths of the rearend to see if it wouldn't be too wide? I can try to get info from someone at toyota.

I still think it would be awesome to have a rwd celica. It would go back to its root from the 1st gen celi. Guys we should make this a sticky and contribute info as we find it, and eventually when we think of everything we need and find the problems to solve before, then someone could build a rwd celi.

I do know a few shops around here that do work on drag cars.
I wonder how you would get the speedo to work...
*laughs*

Although I haven't read everything... I would assume you guys are making this sound a lot harder than it actually is. It all depends on one's ability to custom fabricate strong parts and weld. Tearing out the rear-end of the T20's wouldn't be that difficult, and then finding a proper fitting rear-drive system, also wouldn't be that hard. It's just that, no one is willing to put forth the study time and effort to make a dream possible. I'll tell you right now... it's not a matter of parts... it's a matter of will. I'm willing to bet (if I had a better welder and deeper pockets, and more faith in the T20 chassi) that I can probably dish this out. Parts-wise... IS200/ST205/ST185/ST165 rear-end, custom rear drive-axles, custom driveshaft, IS200 RWD tranny, S series motor/MZ series motor. With those parts... some custom fabrication and welding, you'll be pretty set.

And fallen... I believe the speedo sensor is on the tranny...

Supra engine,tranny,ecu, suspension
Celica Frame and chasie, interior

we were going to get this supra MKIV (don't ask) and then but a 6th gen celica hb and strip both cars down to the frame. and put everything that was on the supra onto the celica.

i know some of you think that could be done but i ask you why not and please don't say cause it coast to much or this wont fit in that or that wont work with his... a car is a car.. wheels turn and all 4 strokes work the same..
