Hey guys I have an 88 TII, with a freshly rebuilt, and street ported motor with RA superseals, and I'm on the stock turbo. now I have an apexi SAFC II and a walboro 255lph fuel pump, i was wondering what size primary and secondary injectors would work best with the rest of my fuel setup in order for me to run 12 psi safely on the stock turbo. I do plan on upgrading to the BNR stage 4 turbo in a few months, and I will get a haltech or microtech when i do upgrade, when i do, what fuel injectors do yall reccomend then?

 

you actually looking at replacing the secondary injectors...keep the primaries stock ( the ones on the engine block). I'd go 1000's...they should provide all the fuel you'll need when you upgrade. Might want to keep an eye out for a nice FPR too...

 

550 plus 720 for your current setup should be fine,if you do get the haltech,microtech and the bigger turbo go with 720 plus 1600 that way if you upgrade again in the future you still have fuel to play with
