Hi I have a 90 gxl with streetport, RB headers and Presilencer then straight back, Intake, RB Aluminum flywheel, all the vacuum crap is taken off so obviously the air pump is gone, motor has approx. 15k on it. What do you guys think?

 

It really depends on alot of things, especially with the street port. How large of a port job is it? I guess 175rwhp, depending on the port job and how its running.
