So im piecing together my kit right now, planning to do 8 psi on stock HG. Just wanted to know how well the auto tranny could hold up to boost, as for the rear diff also. Would an aux tranny oil cooler be necessary?

 

400rwhp is the general consensus for how much the stock tranny (with added tranny cooler) can manage safely.

 

^hes correct 8psi on 2jz, you should be just fine.

 

thanks, that answered my question quick.
