Thanks so much for your time in advance. I have a completely factory 89 CRX SI with d16a6. I'm looking to either turbo or s/c. I see someone selling the JR s/c so that interests me. I need to see what else I might need to make it all work.
But I have a friend that has a fairly complete turbo kit. It uses the factory turbo from a WRX. I want to just run the factory boost 6-7 I believe... no more. I'm not looking for huge gains just a little more fun from the car. As far as tuning. I believe I can use the factory pm6, is that right? I need to get tuned no matter what type of boost I use correct and will that ecu work? What would bringing you the ecu cost to get installed and tuned. Also as far as injectors do I need to upgrade them with only such small boost? How about fuel pump. Like I said I'm not looking for much gain. Probably 150hp.
I'd like to keep the factory exhaust just because I like it quiet. I know that'll keep the hp down but help the spool time. But is it too much of a hinderance though?
Thanks again for your time. Your knowledge is greatly useful.
