I have a JDM B16a and a 99 pr3-3 head. My first build starting from scratch and I'm a little stumped on a few things. What ecu do I need and before I go ordering the parts is there any certain crank or pistons I need for them to match? I Am going to smash it in a 94 civic coupe. I already have the head completely done and the S2 pro series intake mani with 4/1 header and S2 c/a intake along with the AEM fuel rail and pressure gauge. Just need to figure out what harness and ecu I need. I got it from there. THANKS IA
