SOHC ZC/VTEC and NOS

[mrchris1979]

So this is my project that I'm currently doing for my 88 CRX SI. With the SOHC ZC block and the D16Y8 head I did my research and the compression will be about 11.5 to 12. Right now the vtec head is not on the block. The SOHC ZC head/block compression is about 10.0 which is running on stock fuel injectors and fuel pump with an adjustable regulator set at 55 PSI. My a/f gauge says the car is running perfect. Once I put the vtec head on, I probably have to upgrade to higher flowing injectors. I don't want the pain of replacing the stock fuel pump so what is the highest flowing injectors I can use to accomidate the higher compression and an occasional 50 shot of wet NOS (not sure what brand yet) using the stock fuel pump ? (if possible)
