transmission interchangeability
 

hi
i am planning to buy a tarago/previa/estima (tarago here in Australia)

one of the many things i need to confirm before i go head-long into this project is about the transmission.

i should describe my intended 1990-2000 Tarago project...

1. want big fat toyota people cruiser
2. going to unload 2TZ-FE engine and replace with another
3. want 6 speed manual (rear wheel drive only)


---
so my question for the moment is: which gearboxes are interchangeable, or easily adaptable to the existing rear wheel drivetrain?

celica had a 6 speed since 2001 (?) in Australia. the supra was even earlier with 6 speed in 1996ish. both are the C64 and come with models having the 2ZZ-GE engine. (corrolla sportiva and several other internationally)

there is also the V series 6 speed which was V160 and V161 by Getrag.

diff hardening or changing will be easy once the 'box is sorted. adapting _anything_ at the bellhousing will be the nightmare :(

many thanks

anyone know of a good tranmission conversion thread/tutorial somewhere?
