I have a 90 EF SI that i'm dropping my 98 B18B1 into....i guess i'm just gonna stick with OBD2 and buy a OBD conversion harness....i'm having trouble finding one.....Or should i just buy a new Dizzy and Injectors and stay OBD0?
no question - get 90-91 teg distributor and a Chipped PM6 ECU (or a 90-91 PR4 if on a budget) You'll also need either OBD0 injectors (you can use your Si injectors - they'll work fine)
If you wanted to keep the existing distributor (why?) you would probably want to convert to OBD1 not OBD2... You can use your OBD2 dist with an OBD1 ECU, and this would certainly be miles less pain.
bigger injectors would almost necessitate a chipped ECU.
If you want help with this setup, I have something pretty similar... (turbo b18B in 91 CRX HF w/ PM6 + code I wrote)
