allmtr

size?? wat do u mean size? wat year is the b18c ecu. do u mean will they both plug in???

dantastic

it should squeeze into the stock location. if its a obd1 p72, you're going to need a jumper setup to plug into ur 00si.

99-00 Si ECU is p2t. The B18C ECU needs to be 00+ for it to work in a Si I believe.
