You might as well get 310cc injectors. They're not that much more...like a couple bucks more per injector for the RC's. Probably similar price structuring for other brands...MSD, Siemens, etc.

Stock injectors will be ok for now, but if you go with any bigger cams, you might as well get the bigger 310cc's.

Even with ITR cams, I'm having a hard time with leaning out on stock injectors, using a VAFC and adj FPR at 60psi static pressure. But, I don't have a chipped ECU, which extends the limits using a stock 240cc injector fuel system.

 

If ur having a hard time leaning out, why don't you just drop our fuel pressure... doens't that seem kinda high? 60psi....

Thanks for clarifying that. It leans out b/w 6000 and 7000 rpm to high 14:1 AFR's. That's with the fuel pressure turned up to 63psi static pressure.

I won't be going higher than 65psi. From what I've read, the stock fuel pump doesn't like anything close to 75psi of rail pressure.
