do i need to upgrade my injectors? hey all, the new setup is almost done, and i have failed to buy larger injectors, and i'm starting to wonder if i'm going to need larger ones before i get my car tuned or not.
heres what all i have
ls1 (idk if its a m6 or a4, it come out of a 99 c5 corvette i believe it originally had 806 casting heads on it if that helps any.... the joys of a swapped car..)
TSP PRC stage 2.5 heads
TSP MS3
BBK SSI intake with a 92mm ported mouth
PTM 92mm throttle body
Custom .5" throttle body adapter/spacer (4 bolt to 3 bolt)
aftermarket harmonic dampener (not that it really matters? lol)
JTR long tube headers
off road y pipe
hks hi power
the car has summit fuel rails on it, but stock injectors are stock as far as i know. i'm only going to rev the car out to 6200 rpm's for now until i get rod bolts and a better oil pump.
any input would be appreciated,
thanks.

you well probably be almost at its limits with stock injectors wouldn't be a bad idea to upgrade to 36lbs or 42 lbs but you well need to upgrade your fuel pump (that's assuming your using a stock ls1 fuel pump)

alright, thanks guys. i'll keep an eye out for some. a buddy of mine is letting me barrow some 42# injectors until his setup is done... i may just try to buy them off of him.

I bet your duty cycle on those 60# is only 50% or less with that setup... Or 55%
No need for such large injectors unless u have the modding disease, those would be good for boost up to 550 rear wheel, or 625 naturally aspirated.
Some 42# would leave breathing room, and the 255 fuel pump is only good for 8x 51 lb injectors
The stock fuel pump is 190, and is good for 8 x 38 lb injectors, however u can put larger injectors than the fuel pump but you will lose fuel pressure up top if you actually need/ consume that much fuel
