wet shot? dry shot? What kind dampener/balancer/crank pulley do you have? What kind of fuel pump do you have?

it is a dry shot..stock dampner,balancer and pully and it has a focus fuel pump for nitrous...

30# injectors will not be too big, I would not spin that thing anywhere near 6800 with the stock crank pulley. You may want to look into a Mach 1 (5 speed) pulley.

okay so iam going with 30lb injectors, intake manifold do u no of a differance or a better intake the elderbrok or trick flow? and im going to gett he mach 1 pullys..could u help me out on them on where to find and what brand? and i would much rather b safe and get it tuned for 6500rpm ill c what tune guy says thanks alot

get an OEM STOCK pulley, it has to be from a 5 speed Mach 1, the auto's didn't come with a forged crank and aren't balanced for the higher rpms. I found mine used on another forum. The 30# injectors may or may not work, you may have to ask around. I was careful to answer that question before by stating it wouldn't be too big, this I know. With you planning on a 125-150 shot (dry kit) I'd seriosuly question if that's going to be enough injector OR pump. I ran them on my car with heads, cams, full bultons and nitrous and it wasn't too big. I, however, ran a wet kit. So my extra fuel for the N2O was supplied from the fuel rail, not the injectors. As far as intake, I have no personal experience, I used the stock PI.

edelbrock intake for your setup since you have new rotating assembly and heads/cams and can spin it high. and you better get the thing retuned for the shot that you plan to run. Your setup can probably handle lets call it probably right around a 200 shot if you wanna go that big. I'd stick with the 150-175 if they make a 175. What clutch you running??? And you might want to run a 42lb injector. mrtstang runs 42's with a wet kit both on and off the bottle and they work good for him. Might wanna try those.

okay so basically i should get 42s, what i am conserned about is ill pertty much only b spraying at the track so ill b motor on street is the 42s going to b fine on street with no spray? and if i understand correctly ur saying 30lb with dry kit isnt going o work unless i have a bigger fuel rail? as far as intake goes im going to get elderbrok....and i have a Centerforce Stage 2 clutch

like stated before, as long as your tuner knows what he's doing, you'll be fine. mrtstang is running 42lb injectors on his car on and off the spray and when hes not on the spray, he is running just full bolton's, so you should be fine with h/c/i.

the fuel rail should be fine. I don't know if I'd trust the focus pump at that level.
