Well, in this weekend i will finish(i hope!!) removes my head and manifolds. And i think in polish the inlet manifold, because my car is MPFI(Multi port fuel injection), and in this case, the inlet manifold don't receive mixture, only air, because the injectores position is after of inlet manifold. Then, if i polish the inlet manifold, i hope don't have problem of "emulsification" of mixture. Correct? Anybody here before polish the inlet manifold? Gain some horspower??
And about throtle bodie? Can i work in it for pass more air and make more power? My fuel injection (**** LE-Jetronic) will be crazy or not?
Thanks for any help!!
