If I was to purchase a B18C1 with only the block and head, what electronics would I need to run it. I know I would at least need an ECU, are there any aftermarket ECU's for a B18C1. What are the MSD products, are they only for fuel systems? Also, where does the OBD factor come in, is that something I would need to purchase? The electronics are all that I am worried about, I know I'll need a transmission, accesories, ect. Thanks in advance for the info.
