Thinking about changing my stock intake to a cobra set-up w/ 70mm t.b. and also changing to a larger mass air. I can get the mass air calibrated for my stock 19# injectors or I go with a 24# set-up. The car is a 93GT all stock except for 3:73,pullies,cai and some suspension upgrades. Don't want to go crazy with this car, just trying to get some extra h.p. If I did go w/ 24# injectors, would I need to upgrade the stock fuel pump? I'm not sure if changing the injector size is going to gain me anything with the limited mods a have, maybe I should just get the maf for my stock injector size??

You wont need to get a bigger pump. You could get bigger injectors but you wont need them till around 300 wheel hp. It really depends on what kind of heads and cam or if you plan to put nitrous or a supercharger on it ever.

Stick with the 19#ers. You'll need a few more mods to warrant a jump to 24 or higher.
