Guys....

What is the most boost that the stock Z32 internals can handle?

 

I wouldn't go past 17 psi. I like to play it safe though. SGP recomends that you don't go past 21 psi without built internals. That is with sport 500 turbos and upgraded injectors.

 

Z1 recommended 16-17 tops. Stillen said 17. I'll start at 16 and see how that works. I'll bump it up to 17 if all works well at 16. I'm on stock turbos and intercoolers. I'll bump the boost down when it gets hot outside.

 

just dont blow it up
