i bought Bi16A obd2 for $200. The head is fully built except for cams and it has been port and polished. The motor came with DC 4 to 1 headers and an edelbrock intake. No tranny. i wanted to convert the motor to obd0 and throw it in my CRX but after adding up everything i need to make this swap possible im coming out at $2500. My question is instead of bying part by part should i buy an obd0 motor from hmotorsonline and use evrything from that motor to build the one i originally bought?
