does anyone know of a replacement higher flowing injector for the CPI engine. or even what the stock one is rated at, as far as how much HP they are good to.

 

I don't have answers to your direct questions, but the PCM for your engine will be a limiting factor. The engine will only make use of the fuel flowcommanded by that PCM.

 

good point, didnt think of that variable. i do have a JET stage 2 chip but i dont know how much fuel was changed if any at all. We know a couple of local tuners that we use for nitrous but neither can modify my chip. one of them thought he could at least read the program but wouldnt be able to modify tune. I work for a nitrous company but our customer base is mainly corvette, camaro and trans am. so there isnt much insight or care about the s10 or 4.3. everyone tells me go SB but i want to do something different and be able to work on it fairly easy.

 

Have you had a chance to go through our Nitrous, Super Chargers, & Turbo section?

 

yeah i checked it out. 02 Vortec had some good info on the injector in a thread about intake and spider. guess im screwed as far as that goes. lets just hope it will feed the engine as is.
