Whats the max injector size I could run on a 190lph with a jdm b16a head and ls bottom end with forged hardware. High volume fuel rail and blox fpr. Also will be installing a slight cam upgrade like sk2 tuner series cams. Just looking for a good power gain without having to ruin anything.

 

You have some searching to do.

You can run stock to 1000cc. They all will work.

Don't run a blox FPR, get a real one or use stock. Trust me.

Now search

 

93eg, I'm not an expert but i believe even on a na application, stock pumps can't be used with 1000cc. the injectors would be utilized way less than 80%. but yeah I've heard about blox i know they're not good, was just on there when i bought the car, probably just gonna use stock.

 

Lower duty cycle on injectors is a GOOD thing. The stock pump or the 190 will provide proper fuel pressure.

Horsepower dictates fuel needed and at the level you'll be at stock pump and injectors should work fine.

 

Thanks for shining some light down, looks like i had it backwards!
