Ok let me start of by saying yes I know this is an obd1 motor and the car is an obd2a. This swap I'm doing is not for me. I'm helping a friend out who is not very mechanically inclined. I have been doing some research and I know the better candidate for this swap would be the b18b1, unfourtantlly we can not find one in our area for cheap. So this is what we have to work with. So here is what I have gathered so far: B18a1 engine complete minus the dizzy B16 5 speed trans sc4 I think is the number Half shafts and axles Rear engine bracket '99-00 civic si Left hand engine bracket "same as above" Front transmission bracket "same as above" Front engine bracket '94-97 del sol DOCH VTEC ( this is to keep ac ) I also have a shift linkage from the '90-93 Ls I think this will at least get the motor in the car. I shouldnt have a problem getting the motor in the car. Im just going to need some helping with the wiring, ecu selection ect. I keep reading that the difference between the a1 and the b1 is the obd and a couple hp's. Is this true? One of the questions I have trouble finding the answer to is, can I make the b18a1 obd2a to save having to buy/make a jumper harness for the ecu? That way I can run the obd2a ecu and dizzy. Also will the dizzy from a b18b1 fit on a b18a1? Will the axles from the b16 trans fit in the hubs on the 96? I'm sure I will have more questions as the swap goes on. We just started cleaning up the engine. This week we will be replacing timing belt, complete top end gaskets, oil pan gasket, oil and filter, water pump, thermostat, spark plugs, adjusting the vales and other routine maintenance. All help and suggestions will be greatly appreciated.
