You will also have to modify the distributor. Sport compact car did this swap a year or so ago, maybe I can find the mag. It's a pain IMO. The B16A SIR II is so much better IMO and you can get the mcomplete changeover for around $1,700.00 nowadays. How much are you paying? The biggest expensive will be the mounts and tranny converter from hasport. Just give them a call, they will tell you everything you need, they are really cool. I could'nt have completed my CRX without them and their website:thumbup:
