First off you don't need an injector upgrade at this point, and to me 24lbs are the worst choice, they are barely better than 19's, they are the most inaccurate of all motorsport injectors, and aftermarket mass airs just don't seem to get along with them, calibrated or not. I would suggest the larger 76mm C&L into a 65mm motorsport throttle body. Even on a bone stock engine, you will see upper rpm gains. Needs to be tuned tho. if you get a maf get an afpr too, they go hand in hand.

In 1986 they used a 58mm throttle body, 87-93 was a 60mm unit.
