my setup is going to be fast 92/92, ms3 cam, 799's sent out to A.I. and ported to the 226cc, and tsp 1 7/8 headers with tsp true duals.im wondering if 36lb injectors would be enough or should i step up to 42lb injectors, or would 42lb be too much. right now it would be on the stock fuel pump in a 99 camaro but im looking into the racetronix fuel pump kit. any advise would be greatly appreciated.

36s would be ok, 42s would be ok also. I've run both. Depends on your future plans for the car honestly.

Step up your fuel pump, 36lb will be all good or go 42lbs if you think in the future you may go F1 or O2 etc

this is way more then my plans had ever been so i dont see me upgrading much after this accept for trans and rear end. and i figured i would go with the racetronix fuel pump kit, would that be good enough?

Racetronix will be good, I got a Walboro, I just got one of those over the RT because I could get one local and the car was apart at the time and I was trying to get it back as quickly as possible. I was originally going to run the FAST 39lb, but ended up with some 42lbs FIC injectors, either way you should be fine. However, you might want to just get some 42's. I never planned on it, but now I'm adding a 150 shot on my car and I dont have to worry about fueling. Just a thought.

36 or 42 # with that racetronix or equivalent 255 l/ph pump will suffice perfectly.

you will have to change the tune, especially the IFR table Injector flow rate prior to running the car with the new injectors

i think that im just going to go with the racetronix because my buddy had it and it was so simple to install. thanks for the info on the walbro though. and i will deffinatly not be the one tuning this, i dont know that much about it and after all the money im putting in the car im not blowing it up, but thanks for the info.

I would go ahead and install the RT harness as well.

I believe the RT pump is basically a better fitting Walbro.
