Which 3sgte is more suitable, Fwd -> Rwd Options

[dudeofchaos]

I have a project planned for my celica and I just had some questions for you guys.

I will be going for a Fwd to Rwd conversion so I wanted to know which 3sgte is more suitable for the swap?
I believe both (mr2's and celica's) 3sgte are trans. mounted? So is there one of them that would be easyer to fit to a Rwd tranny?

Also if you guys could come up to me with some parts I would have to change (and from which car I could take these from if possible) and stuff I would need to do I would appreciate it.

I know I would have to get these:
-Drive shaft
-Differential
-Probably change the whole rear suspention parts
-Rwd tranny

That's what's on the top of my head but I surely forget many things.
Don't worry, I will not get into this before I will have enough knowledge. I will soon study in car mecanic before I begin all this.

Thanks for your help!

(in ascending order of price of gearbox) W58 (NA jzx80) would be fine, J160 (6speed is200) R154 (5speed jza70, jzx100, jzz30) would be better and V160 (6speed jzx80 TT) even better then that.

doesnt matter which 3s you use as all gte engines are mounted transverse only, the mr2 maybe slightly better because of the alternator location.

you could get a rwd arse end from a 205 and use that,

then custom propshaft (1 piece, or 2 piece with custom bearing support in the middle)

You need to change the steering rack. As the 20x ones are mounted up near the firewall where the gearbox will be you need to get something from say a supra, to get something that mounts low under the engine.

Naturally wiring will need to be changed, but thats not a biggie.

Custom engine mounts obviously. While the turbo side isnt difficult the inlet side is more annoying because there isnt provisions there for mounting north-south, what needs to be done is to get a big plate of say 6mm steel so you can utilise 3 or 4 bolts into the block, then weld the mounts onto that.


You need a transmission tunnel, this is one of the bigger hastles. Best bet IMO is to get a tunnel from the same sort of car you get the gearbox from (that way you know the tunnel will be big enough for the box, the r154 and v160 aren't a small gearbox.
Obviously this is going to fnck up your centre console, its likely you wont be able to run the stock heaterbox because the transmission tunnel is that much bigger on rwd.

You will need to change the front hubs, or modify them so they dont require a driveshaft and nut anymore.

When the 3s-gte is mounted north-south the turbo is facing backwards, so at the very least a custom exhaust manifold is required, also the turbo will be on the passenger side (well drivers side for you people) so you will have to be careful with regard to how close the turbo and dump pipe is to your master cylinders.

You will probably find the inlet manifold will hit on the bonnet so a custom inlet may also be required.

The coolant block on the back of the motor (where coolant hoses and temp sensors are) is on the back of the block, meaning that needs pretty well to be removed unless you mount your gte way forward in the engine bay (and risk upsetting the cars balance) Along with that the distributer is also on the back and the same location problem arrises.

It would be easier to get a beams 3s-ge from an altezza as they are already rwd.

Im sure ive missed lots, but this gives you a bit of an idea of whats infront of you.
