I have a 90 gt with a trick flow upper and lower intake, cold air, 70mm throttle body, underdrive pulleys, full exhaust....im trying to figure out what size injectors, mass air and fuel pump to run?? the block and heads are stock...anyone have any ideas??

There's a formula to use, I don't have it. 24# and a 190lph will cover what you have, but a 255lph and 30# tuned would be better, once u get heads.

I wouldn't bother upgrading until you need it. Your stock fuel system is just fine right now.
