direct port nitrous injector sizes

[Mod Monster1]

Hey whats up eveybody! I was wondering if anyone knows if the 19 lb injecters are good with a 125 shot of direct port with the NX kits?

Thats probably not a good idea. I'd get a set of 36 or 42 # injectors, and perhaps a bigger fuel pump. Biggest thing with any FI car is you don't want it to lean out on the top end of the RPM range, and personally putting 125 additional HP on the car - I wouldn't feel comfortable running the stock fuel system on it. I'm actually gonna be selling my old 42's if your interested, PM me.

in a direct port or wet setup you will be fine, you should upgrade the fuel pump. the injectors don't spary the extra fuel in either of those setups but the fuel pump does have to supply that extra fuel.

what direct port NX setup is this?

I belive the part # is nxp80000-efi. I already had my heart set on a focus pump. The bottom end i have put together will handle the shot no problem with the tune through a PMS. I still may up them to 24 or 30 # but that may be later on. I appreciate the input guys and thats pretty much what I figured too but its good to have extra advice too. With VT2s and 10 to 1 compression on the juice i should be able to throw down an easy 400 whp. With slicks and suspension I am shooting for the 11's.
