I am going to be purchasing a b18c-r motor in the coming weeks , but I had a few questions regarding it. First off, this is going in a 1994 GSR. As far as OBD-1 conversion, do I need an entire new dizzy? Or can I just reqire the OBD-2 dizzy for OBD-1. I also am going to be using a hondata chiped p72 ecu. Is there any other things I must consider when doing this swap? Is it easy to convert obd-2 to obd-1 as far as engine wiring harness? thanks

 

Essentially you'll just need to keep the dizzy from the stock engine as well as the injectors. Keep the complete engine wiring harness from the stock engine as well. I'm not sure if the alternator plugs are different, so if they are then you'll also need to use the alternator from the stock engine. Everything should plug right up, you may need to lengthen/shorten a few wires, but nothing major. I'm not sure about throttle cable fitment either, but I think the stock throttle cable will work as well. There will be no secondary butterflies on the intake manifold so don't be surprised when you have one thing left unplugged from the original wiring harness.

 

thanks for your reply, one more quick question tho. does the intake maifold on the b18c-r motor have a tap for my evap canister? how do I hook up the EVAP since I am in california and need to get by smog. thanks

 

Hooking up your evap will be easy. You just need to run a hose from your canister to the evap solenoid, then from the solenoid the the intake mani. If you need help I'll send you pics.
