i don't know what he wants to do...i drive a 240 with a sr20det my motor stock is good for like 500 at the crank so i don't have to worry about internals.....i just need to upgrade the turbo injectors and get a rom tune.....going to a t28 with a front mount should put me in the 300s with all the upgrades listed above...a little easier with the nissan...i guess.....but thanks for you helpfull insite spoolin
