Some s/c Q's
Any suggestions on parts/gauges/plugs to get with a stock block/head car with a 6 lb vortech s trim. Any parts that you think I need for this would be very helpful, down to which injectors and plugs, anything that I would need to make my car run nicely.

1) you should buy boost/fuel pressure guage
2) run 1-2 step colder plug (Autolite 103 or 104 copper. But I run NGK-TR 6
3) Replace stock 24# injector, go with 30# or 42# you must reprogram for those injector.
4) Don't beat on it until you get it tunned for proper fuel curve.
5) Even 6 # of boost can damage piston with slight detonation
6)You should at least replace stock fuel pump, go with Walbro 225lph

Re: Some s/c Q's (Bruce)
Alright, I will have some 30# injectors, boost gauge, and T-Rex fuel pump.
I have a question though, why are all the fuel pressure gauges saying that they need to be mounted outside the car?
And I can reprogram my ECM for the 30# injectors, but what would have to be done about the fuel curve?
Also why is it important to go with a colder plug?
Thanks!

If I am correct, some fuel pressure gauges are mechanical and actually have fuel running to them, you don't want that in the interior of your car, find an electric one. I'm pretty sure Autometer will have some

You might consider, time permitting doing some serious reading and conceptual thought before you destroy something of value. Your comment regarding reprogramming the ECMU for the new injectors and then asking about the fuel curve reveals your "current" lack of understanding. This of course can be vastly improved with some reading and research effort on your part. Forget the gauges unless your attempting to impress someone. Or, if you really feel the need make sure their immediately in your line of sight on the dash. If you locate them in the side pillar the likely hood of you glancing at them is nil. You'll be holding on to the steering wheel for dear life and glancing at the gauges will be the last thing on your mind. Besides, once you know the boost output of the engine it seldom if ever changes. Realistically speaking, once the "program" is set you maintain fuel pressure. If you lose fuel pressure on a run you will know instantly and so will your pistons. Good Luck.
