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!

I have the 228r n stock 241's and at the time ls6 intake n my injectors were maxed at 112% duty cycle . I got a FAST 90/90 n went up a set of 42's n then I was good

the car is a 2000. i was planning on either 36lbers or the svo 30s. just wanna make sure i dont get this stuff installed and be missing something crucial like getting enough fuel for it.

SVO 30s. Dont trust your stockers.

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.

The SVO @ 4bar is 36#'s.

I dunno about the fast but yes the SVO 30 is rated at 36 at our pressure.

2000RDT/A

well the svo should at bare minimum cover my application then is what im getting out of all this. id rather go with them soley because my trans am is red and im trying to keep the red theme in the engine bay and theyd make a nice accent haha

Learn something new. 01-02's have 28#s? nice.

Wait, so you shouldn't drive the car with new injectors until it is tuned? I was gonna have mine installed and then drive about 45 miles to have them tuned will this cause any serious damage?
