my 1990 turbo II has a large streetport, stock turbo, and stock ecu. after I have power FC installed, i want to get it tuned run 12psi off the stock turbo.

question:

1. is the stock turbo too small to use having a large streetport?

2. can I run stock injectors at that boost level? if not what injector size do you recommend?

3. is there an injector size limit you can run on stock fuel rail?

boost pressure will drop down to around 7psi by redline.

720/720

not that i know of.

in that case what size turbo would you recommend to reach 300-350whp? i'm sure the street port and upgrading to FMIC should help it out easily. so i'm not gonna need that huge of a turbo. and will 720/720 injectors still work around that power range?

BNR stage 1-3 hybrids will get you in that power range. Four 720s should be enough to handle the airflow.
