Agree with Mike. The proper way to change over from carbs to FI if you want to use factory parts is to have a complete donor car to ensure you have all the bits. ECU, harness, relays, sensors, AFM, fuel pump, etc. Unless you already have the donor, one will probably cost a couple hundred. Another alternative, probably more costly but well worth it, is to get just the intake manifold with the injectors and fuel rail and the fuel pump, thats it. Purchase the SDS fuel management system for about $750 which replaces the ECU and harness, eliminates the AFM and provide programability. The system is easy to install and setup but it helps if you have some mechanical skills. If that is too costly or complex, then look at early carbs as Mike advised. However, unless you find a set cheap (right!) you might be surprised at the final cost and you cant beat the driveability of FI and the tuning potential of a management system.

Thanks for the help, so far i just have the l28 motor complete with all the sensors and manifolds with injecters. i hope to scroung up the harnes next, i guess they are all alike. thanks again.
