The later Camry V6 gearboxes are actually better than the MR2 version, stronger gears, etc, but NO LSD though.
I'm looking at installing a Camry 1MZ-FE V6 into my car. The matching gearbox would be good.
And considering an MR2 box goes for over a grand, it might be an option to get an LSD later.
I've driven a manual 3.5L Magna VRX & they light up one wheel very easily.
CamryGT?, can you pm me your contact's details, as I'm trying to source a whole half cut that I could use.
