Fuel Injectors
#2
A pair of 720cc will do fine for the secondaries. They'll most likely be low impedance when they're that large. If so then you'll need resistors to get them up in impedance. All you need is a pair of 10 Ohm 10 Watt resistors from Radio Shack and some sort of piggyback fuel computer. The resistors are only a cople of bucks and the injectors shouldn't put you back any more than $120 each. Most people seem to get the Apex-i S-AFC. I got the HKS S-AFR. It's easy to use, less expensive, more flexible, less complicated with excess gadgets, and doesn't stick out like a turd in a punchbowl.
Get the injectors on there and wire up the piggyback. Then stay off the boost until you can get to a dyno to tune your car. Do this or pop your engine. Use a wideband a/f sensor to help tune the injectors right.
Do you have an upgraded fuel pump yet? If not, get a Walbro 255lph pump immediately. Those things are perfect for what you have right now.
