i am running a 75 shot zex, with ZEX plugs, 93 octane w/a can of octane booster, stock timing. I pulled my old Denso stock plugs today and found they were black and I assume that its because my b16a2 swap was installed with a GSR ecu. So could I used a smaller fuel pin for the 75 shot such as a 34/36 instead of a 32. lemme know!

thanks,
mike

 

you could, but i dont know if i would. the B16A has the same injectors (270cc) and fuel pump (135 lph) as a gs-r, so i would imagine the fuel maps are similar. and especially on a dry kit, such as the zex, if you lean out the fuel mixture, youre gonna detonate, and burn up some exhaust valves. but its your baby.

 

yea, i also figure, more nitrous isn't good without more fuel..
so i left it
