Parts yard prices:
Injectors are $20 each used.
Selenoid resistor $5-$10.

Just called this morning, and I don't even know the guy.

On resistors -

Really, the easiest way is to get 10ohm, 10watt resistors from Radio Shack. My old roommate Jay has been running 4 720cc injectors with these resistors for well over a year now with ZERO problems. Not to mention they're like 2 for 99 cents or so. Wiring in the resistor block is one way to do it, but it's a lot more cumbersome. These resistors are heavy duty, and designed to dissipate quite a bit of heat. I just wired them in next to the injector when I cut the injector plug off to wire in the new plug.

Also, the total best way to do it is to run 720's all the way around - Jay found, with a wideband, the car runs VERY lean before the crossover, and at full boost/load at a higher gear, that's motor poppin' time.

With 720's all around you need a Super-AFC to tune 'em in - with them tuned right, the car will idle as well as or better than stock.

Yeah, you can run the secondaries with no Super-AFC, but you will bog/lose power at the top end.
