What injectors? modded LS6
 

motor is a cammed LS6 with LTs and catback, ported TB and lid, i need to buy injectors ASAP so i need to figure out size and brand... suggestions?

also the motor MAY be supercharged in the future so a larger than needed injector right now may be a good idea. It'll be tuned before its really driven, so thats not really an issue with running untuned w/larger injectors.

i was looking at racetronic #42 and similar.... opinions/suggetsions?

run it on a dyno first. Depending on the tune I doubt you will need them. Seen plenty of cars with 400rwhp with stock injectors.


Now if you had NOS or a supercharger, yes get a inline FP and injectors.

you will run out of injector with those racetronics injectors if you go FI, but if you go big NA theres a strong possibility you'll run into tuning issues from what I hear with the stock pcm. Personally I've never done anything larger then the racetronics 42lbers but I hear all kinda issues once you go much larger. Also consider the racetronics injectors you speak of are rated at 43.5psi...whereas LS1's have a stock FP of 58psi meaning those 42lbers are actually more like 50lb injectors.

so.. svo 30s?

If i do go FI, changing injectors wouldnt be too hard so let me not base my choice now on that, and in the future i mean at least a year.

Bandit, currently i have NO injectors, so i need something

the racetronics 42's would be a fine choice for right now with what you have and even if you decided to go with a huge stroker motor they'd be fine...but when you add boost into the picture they become too small very quickly.

bill, but could you tune my car with the racetronic #42s or will there be issues.. i'll get whatevers easier for you and what you recommend. and liek i said if i do go FI, then i'll just upgrade injectors then.

another option i found were SVO flowmatched #38...

i want to order a set tomorrow so i'll have them by the weekend...

like I've said I've tuned a couple of cars with the racetronics with little or no issues...i cant guarantee anything larger then them NOT having issues though.

ur stock ones will be fine for the time being. Your setup is very mild , poke around on ls1tech alot of cam only guys are still runing stock injectors, i whould wait till u get ur S/C setup befor u spend the $ on thoes

once again ill state..i dont have stock injectors, i have NO injectors. anyways, i bought a set already
