I'm getting a 3sgte from a st205 celica half cut in my sv21 camry, hopefully starting this week.
I looked at a mr2 turbo tranny too. But of course the shift lever things are on the wrong side of the box.
I have a widebody camry V6 box sitting on the floor at the mechanics, next to a 4 cyl camry box which is probably the same as the 4 cyl box in old celicas. The V6 box has the identical bolt pattern to the 4 cyl camry box.
It looks heaps more solid than the 4 cyl box.
My brother has a V6 camry sportivo manual and its transmission code is E153 which I am pretty sure is the same code as the MR2 turbo, so it should be strong enough.
The V6 makes something like 280Nm of torque and a 3sgte makes something like 305Nm so It should hold up OK anyhow.
The driveshafts for the V6 box have splines that are ALLOT bigger than the 4 cyl ones in the camry/probably celica, so will need some sort of custom shafts.
My mechanic has a widebody camry with a ST185 motor already in it. He ran the stock 4 cyl box for a few months, apparently it copped a flogging but never broke.
He got his GT4 box converted to 2WD, but they stuffed it up and it still sends torque to the (not connected) back wheels, drives like an auto with no oil, sounds bloody funny when you here it comming down the road. He didn't pay them, so can't tell you what it would cost.
The V6 box is much lighter than the GT4 box and looks like a much better option. I paid $330  for mine from Newcastle Auto dismantlers (in NSW), looks like it is in good condition and he recons he can get more for that price.
Some websites recon late model camrys have LSD's but my brothers sportivo doesn't appear to be a LSD. I'm not worried at this stage though.
Mr2 halfcuts have a few differences to GT4's. I think they are mostly brackets for alternators, ps pumps etc also the GT4s make a bit more power another 10KW or so, different turbo I think steel vrs ceramic mabye?
My mechanics recons GT4's are easier so I went will that.
Can get pics of gearboxs etc if you like, have a search on the web I have seen a few sites with info on 3sgte into celica swaps
also I should know more about clutch/driveshaft options later this week
