Well I think I'm about to run out of bolt-ons. I think all I have left is a plenum and tb. my questions are what size are the stock fuel injectors? are there any other benefits other than the obvious one? and what all to I need to upgrade go with bigger injectors? are there any suggestions as to what i should do besides this? thanks for the advice.

what cam you used from comp?

 

Master, They are called Xtreme Energy cam. Its got 113 degree lobe seperation, .550 lift, and duration is 234/238.

Anybody want to give me some advice of injectors?

 

Your car came with 19# stock. I would recommend a 75mm tb/plenum and 24# injectors with a match tuned 85mm MAF. Ebay has the new Pro M MAFs for $280 or so and you can get them programed for whatever injector you need. I think seller "coolblueperformance" sells them. Anyway, you may even look at 30#. Code is the N/A king and is running 30# with more done than you so far, so I'd think 24# would work well.

 

 

How are you running well with stock TB/plenum and injectors and so much head/cam work?

 

i was wondering the same thing.. especially when he has stage 2 !!!

 

Damn, I should have asked that!

 

Well as you guys have probably guessed i bought the car with all the mods but the pullies and CAI. Needless to say I've learned a lot in the year that I've owned the car. As far as running on a stock TB, plenum, and injectors that's part of why I asked. As I learn more, more questions come up. Anyways, sometimes I feel some hesitation but I don't know how it felt before the head/cam work. Will engine response smooth out after the mods?

 

I was under the understanding that if you had a 99 or newer 4.6 there was no map adjustment needed just to change the injectors? I may be wrong but I red that some place.
