ahhhh okie dokie... that makes me feel a bit better lol
i'm only gonna run bout 15psi and my compression is 8.0:1
well... in theory... with correct machining and forged bits and metal hg it should be able to take a hammering
i think a t3/t4 will be a bit small to be honest... look at going bigger t04 or even with an SP series turbo
the stock turbo is a Toyota CT26 (i believe the only car manufacturer that has brought out it's own turbo)
the stock turbo can pull about 250whp in good condition but once upgraded it can pull 3-400whp depending on the compressor size... once you start going 60 - 62 trim they do start becoming unreliable
good luck on the monster and be sure to keep updating
