I have a 93 formula in my garage, waiting for a fuel upgrade. I just installed the hot cam kit , with a 3200 stall. My question is what should I get a Fuel Pressure Reg, fuel pump, or/and bigger injectors(how big)?
Right now I have the stock 24's
Thanks for the help

As long as your fuel pressure is in the normal range for your car I wouldn't install a new pump or injectors just for the hotcam. The stock fuel system is enough to handle the HP increase from the hotcam. The stock fuel system on LT1's is supposedly good for up to 400hp (at motor not rwhp) I think the injectors on your 93 are actually 22lb not 24 like the 94-97's. I've heard an AFPR is really helpfull though on 93's and people have gotten gains of up to 10hp or more by leaning out the A/F ratio with one. Might want to search some posts about it for more info.
