ummm to be honest you should prolly go with the 36#....42# is not normal with a setup like yours and they will make your car burn a little too rich

36s would be good if someone makes them. I know Racetronix sells 37s.

Just a word of caution on accell...I had a set and out of the boxed one flowed enough to burn out a cylinder before I could get the car on the dyno...I'm sure other people what had good luck with them but I haven't...go 42lbs and i'm sure you can tune them fine.

I have the basic same set up and Lloyd Elliot said 30# injectors would be fine, Im going with 36 or the 7s just to be safe plus I know I will be doing future mods to the car.

What kind of injectors do you have? SVOs? Also, what is your fuel pressure? It seems to me that you could increase the fuel pressure a little to get the injectors to operate under 85% duty cycle.

Currently have SVO 30# injectors. Pressure from stock pump is good at ~37# & 44# or so. Racetronix 37#ers are on the way.
