hi there im new to rs turbos i have a 1800 zvh in my s2 running mfi
how far can i push the standard injectors?

plus i know its bad but i have slimmed pistons and want to know whats my boost limit?

the zvh is only til i have a big spec 2.1 in the winter i just want the car running for the summer

 

14psi boost max.

Std injectors aren't the issue, it's the calibration of the meteting head - but around 220hp is a sensible figure.
