1.6l injectors are 205cc, and 1.8l injectors are 230cc. What's wrong with keeping the original injectors with IRTBs? The only reason I can see to switch them out is if you're going to be blowing through the throttle bodies with a super or turbo.
Yea, I talked the Russ Collins (owner of RC Eng.) since I posted last and he recomended just having a set of stock ones blueprinted. And he only charges $27 (retail) per injector, sounds reasonable to me.
