I recently purchased a 91 13b to install in my sand rail and I'm having a problem fining out wich sensors and connections are absolutly necesary for the engine to run properly. I have a service manual that gives me little informaion on this matter. If any one knows what I need to keep and what I can remove that would be great.
Thanks

Assuming the stock ECU:

-AFM
-CAS
-Pressure/boost sensor
-TPS
-CLT
-IAT

Non sensor stuff needed:
-Metering oil pump
-Stock ignition coils
-Injectors, etc.

Turbo or NA? If turbo there is also a twin scroll and boost control solenoid.

Yes I will be using the stock ecu. Its a N/A engine that is bone stock. That's great if I can get away with just those few items it will make it fairly easy to build a harness. I have built many wire harnesses and messed with a whole lot of ECM's but only with heavy machinery, so the transition to the automotive side is a bit awkward for me. Can I just send power to the ecu and let it do its thing or do I need to give it some other source of input? Thanks for the help

Yep, you can just power the ECU and it will run the engine. Note that the CAS and coil wiring is on the body harness, so you'll need to recreate that on your new harness.

Done this many times myself to put 13Bs into other vehicles.
