Which size injectors does anyone recommend for secondary in a pretty well modded 87 Turbo II with a Rtek 1.7 ecu. I need new secondary injectors and cannot decide between 1000cc or 1600cc. which ones should I use and why?

 

1600cc seems to be killing it if you're not running huge hp numbers. I'm personally gonna run 4x 760cc injectors in my car. I might go bigger later on.

 

I am using 1600's on a half bridge with a t78 and standalone so those will be overkill for you.

 

i thought 1.7 was made for 720cc's?

 

depends on the turbo and the psi numbers you plan to run, what exactly you are running. From what I would assume, you are probably running larger intake, exhaust, ported WG (? or larger turbo, posssilby bnr) and of course your Rtek. I would go with nothing larger than 1000 if you plan to run ~10 psi, and that is even borderline.

Edit: 1.7 requires 720cc 2ndaries.
