convertin from 4wd-rwd

Postby Lamphant » Wed Jun 08, 2005 7:45 pm

hi there again, ummm i would like to kno of it would make any sense to convert a ae114 (4wd corolla) rwd. i am actually tink about doing it 2 be different from the ppl here in Barbados. so i would like to kno, from anyone who has an idea, what would bethe best rearend to use, would i have to change my front suspension for one from a rwd car, and what about the rearend. that is my main concern. are there any rear-ends the same length and measurements as that of the ae114.

i was told that the hachiroku rearend would be good, but it wouldn't survive big power. (planning on usin a twincharged 4agzte engine)

ur thoughts and comments are welcomed

Why would you want to convert a 4WD to a RWD?

4WDs are absolutely brilliant for track driving and high speed cornering IMO.

As I said in a previous post, doing it to a 4WD car is nowhere near as hard as a FWD, most obviously because of the rear-end setup and transmission tunnel.

First off, decide what rear you want, to keep it IRS (I'd say cheaper), or go for a solid rear. IRS, I'd look at larger LSD units out of other RWD toyotas, or just getting one and having halfshafts made up to fit, maybe see if you can find a whole donor car with rear discs etc. as well. For a solid rear, I wouldn't piss around with an AE86 rear end, they're far too hard to find, and you'd easily get a Hilux LSD rear for the amount you'd pay for an AE86 LSD rear end. Add to that, the conversion from IRS to solid rear won't be cheap, as they'd need to make new mounting points up.

Front end, the problem with 4wd cars is that the chassis rails rise up like fwd cars, to make room for the half shafts. You'd either need to hunt out a rwd crossmember (maybe AE86? anyone?) or get your one custom made to suit a RWD application. Not too sure on the size of the hole in the firewall for the gearbox, but you may need to enlarge it to fit say, a T50, or W5* if you're going high-power.

The rest is fairly simple, just get a custom driveshaft made up, drop in whatever motor you desire, get it wired up, and you're away laughing!

I would get a crashed GT4, and put every thing from it into the car, that would be far easier, and you could still use the 4WD, and have a nice motor to go with it.

Far quicker than a 4agzte, and you wont have any of the handling problems of converting a 4WD to RWD.

If you must go RWD though, use an older IRS celica rear end, it should hold all the power you'll need.

Yeah, early to late 80's rwd Celica/Supras would be mint as donor cars.

Here are a couple of pics from the AE101 we converted to RWD.

The first one is the size of the tunnel and recess in the firewall to get the 2JZGTE and gearbox in,

The second one shows where the motor is placed and you can see why the tunnel is so large.

Jesus Christ Matt, thats nuts 8O

Look how far back the gear shifter is!! Needless to say, I don't think you managed to get a full dash (aircon, stereo etc) in there!!
Motorsport is like sex. You could take it to track and have a long, enjoyable session, or you could take it to the strip and get it over with in less than 20 seconds.

Whats the problem with the front suspension? Just split the Cv in half, and run the stub axle alone. This means you can run standard suspension at the front - no pissing around with ae86 crossmembers etc.

would yall guys recommend me getting a wrecked ST185/205 gt4 celica and using it as a donor car for my project? i was tinking that i could use the suspension, brakes complete rear axle, engine gearbox, ecu harness and whole drivetrain, and transfer them into the AE114 body, and leave the car 4wd and it would be the ultimate sleeper?

what are yall thoughts and is it best i use the ST185 or the ST205celica as a donor

You tend to find your steering rack is running through your bellhousing then....

Do you realise how high the engine would have to be for the rack to make it under the bellhousing???


That is one of the main problems.

There is a solution but it requires replacing almost all the front suspension and fabricating new stuff.
