    This is what most people use:

    65lbs. on stock injectors is very high. I had a friend running high 12's afrs running an E1 wheel turning 8600. He had to get 550 cc ones. You can get them off of ebay. Search for pink sti injectors 550 cc. Be careful, you might be running very lean and it could cost you big money.

    That vibration is normal with that wheel. Those injectors are very big. We run 550 cc's with that wheel. Some have gotten away running stock injectors but when it gets cooler the 550 cc injectors are needed. Not sure what rrfpr you have but you loosen the nut and adjust with an allen wrench to the desired fuel pressure. Hope you have a gauge on your rrfpr.
