What year is the car? If it is a 01-02 car chances are the factory 28.8 lb injectors will be fine. If you want to upgrade, you can go to a FAST 36 lb or SVO 30 lb injector. Either one should get you fixed up! We have both in stock and ready to go!

The 2000 car is going to have a 26 lb injector. You will probably want to change them. SVO 30's will work and are fairly inexpensive. Be sure to tune the car before you fire it on the new injectors. You don't want to wash out the rings.

Go with 36's in my opinion if your going to do anything else it will give you room to grow that's what I am running right now.

Don't the SVO 30 lb injectors flow 36# on LSX cars? I remember reading that somewhere on this site. If yes does that make the SVO and Fast 36# pretty much equal?

I dont think so, the FAST are most likely rated at 36lb/hr @ 3bar (43.5 psi). So they would be around 40-41lb/hr @ 4bar (58psi) which is what LS engines run at.
