Just wondering what lb. injectors the ls1 has stock, and what lb. injectors would be good to upgrade to??

28#'ers in the 98's. Upgrade size depends greatly on what you plan on doing. Probably wouldn't want to put 60#'s in a cam-only car, and wouldn't want to put SVO 30's in a TT408.

for a little while they had 26#ers
then they had 28.8#ers

what power you looking to make, most cars around here that are 450HP will be fine on some 42# injectors (rated @43.5psi) or 50lb injectors


60# mototrons WILL NOT WORK unless you got some serious mods and some serious idle airflow to take advantage of that huge of an injector. or unless you want a really rich idle. I tried them on my car

I am looking to do full bolt ons, and heads and cam, and some other stuff in between so probably right around that range of 450hp.

My car has 450rwhp and it still runs the stock injescors however they are maxed out completely. Im upgrading to 42lb. injectors and the Racetronics fuel pump.
