2 Questions:
1) Can I install the JRPC and still run the car without the SC first?
2) Does anyone have a pdf file or link for the instructions?


Thanks!

You can run just fine with the unit installed and no SC. I'm running NA right now with the PC-pro. Don't recall if the wiring is different for the JRPC but here is the diagram for the PC-pro http://www.fastforwardsuperchargers.com/Install/PC-Pro_Wiring.pdf
I bet Moss can give you the old JRPC instructions.

The JRPC has 6 wires. Red to +12VDC. Black to GND. One of the four wires is a different color and should got to injector #1. The other 3 wires go to the other 3 injectors in any order.

Why would you want a JRPC installed without forced induction? I thought they did nothing until they see boost. It shouldn't do any harm, but it won't do a thing...

what spark plugs are recommended for the BRP/FFSC kit so i can walk into kragens without describing it.

For my kits, I supply the NGK BKR7EIX for the 94-00 and the NGK BKR8EIX for the 01-05. Only NGK.

BEFORE I upped the boost with a 62.5mm SC pulley, I ran NGK BKR6E and BKR6EIX on my JRSC M45.

If you insist on running the old Powercard, I'd suggest you find a way to enrichen the mixture at part-throttle (FM's O2 clamp is supposed to work). I couldn't find anything that I liked so I ended up with Tom's PC-Pro, modified for the M45 - best add-on to the kit.

Might run rich but should be safe.

that worries me. are there issues with the old JRPC that i should know? will my engine blow if i mash on the throttle?
