i would likw to know if i need to go up to 24's. RIght now, i dropped in the motor with all the stock parts i had on, maf, tb. The only differerence is that i used the stock explorer injectors, and the explorer FPR, dunnno if this will do anything. I realize that i need larger tb, and a maf, but i dont want to buy a maf for the wrong size injectors. I guess the Explorer injectors, while being yellow like ours Do flow more than our stock ones, but is that enough? they were for the motor before, all i have changed is the cam. Later i might try to get teh Explorer tb on. should i leave it as is, maby just get a adj. fpr, or go allout with new 24's etc? thanks!
