whats the most boost you can run out of a 87 TIIs stock turbo i forgot again. lol

 

anything over 15psi is just blowing hot air so to say

 

anything past 10-11psi with the stock intercooler/turbo setup is out of the efficiency range. Also, it's mpossible to not get boost creep without porting the wastegate, so on a totally stock turbo, when you want like 10-11 ,you'll end up with like, 20. Port the wastegate, get a new fuel pump, a fuel cut defender, and then you'll be A-OK to run 11psi.

 

shweet thanks guys.
