Hey guys, im have a 1990 civic hb with a d16a6 and im goona build the motor with ductile iron sleeves,closed deck,forged l/c pistons,and h rods, and turbo it to like 15-20 psi so should i get 450 or 550cc injectors? Also what fuel managment do i need besides a high flow intank fuel pump, will a hondata be all? These are expensive 2 is ther anything else i could do?

 

A balla like you would be limited by 550cc. Go ahead and grab the 750cc or the like.
