Actually a 1jz into a ta22 would be ILLEGAL in NSW regardles of which engineer you try to get to pass it as it does not comply to the weight to turbo capacity ruling .
even if you could get it passed
For all the extreme modding involve which would mean a custom crossmember as the engine is WAY to tall to fit under a 22 bonnet .
It would be cheaper to fit a 1ggte and whack on a gt3040 .even with stock ecu it wil runs low to mid 12's and still handle
that would kick some stock 1j butt
Actaully my red Celica is a TA23 same as RA but came stock with 2t not 18r
