okay, i hear that if you revert back to obdI using a 93-96 prelude ecu, you need the following:

wiring harness
obdI computer
distributor
injectors (4)

however, you can also use a GSR ECU programmed to Prelude specs and that doesnt require new injectors or a distributor.. is this correct? But doesnt it cost almost $300+ to reprogram the ECU??? is this still cheaper than buying injectors? help help!

You also need a resistor pack if you use the 93-96 ECU and injectors.

If you use the GS-R ECU, it doesn't require the use of new injectors, but you also need an OBD1 distributor.

I don't know for sure if you need to program the ECU. I did mine because I wanted it optimized, and a higher rev limit (8500), but I have heard of people using stock program GS-R ECU's on the older Preludes.

BTW, I will probably be selling my OBD1 set-up in the near future. E-mail me privately if interested.
