What injector should i use/ How much power will i make.
LQ4 6.0L with :
Ls6 Intake Mani w/LS1 Maf
Vengeance VRX5 Cam (236/238 .601/.605) 113+2 LSA
Longtube Kooks Headers into full 3inch uncatted/un resonated exhaust
titanium springs w/hardened pushrods
Running LS6 OEM 28lb Injectors. Swapping this motor into my nissan 300zx this winter.
will i need bigger? ive heard the OEM ls6's are good for 430ish RWHP at like 90% duty.
Do you think i will need bigger injectors? ive been reading on SVO 30lb.. but i cant find pigtails and if i dont need them i sont want to spend the money.

30's is pretty close to what you have ( I believe the stock injectors are 28.8's) , if you want some stock gm injectors with the same connector I have some L67 ( 3800 supercharged) 36# injectors 8 shipped for $100 and the injector data is right in any stock l67 tune in hpt tune repository. These are identical to the FAST 36's. I part out some w body cars.

The Ford green-tops are popular. I believe they are a 42lb/hr injector. I run the Accel 44lb/hr injectors. There are several different companies out there that make them. Your best bet is looking through the classifieds on here. With so many people going to turbo setups, they're plentiful and cheap at that. Those guys need way more injector, so they're just looking to dump them at fairly cheap prices.

So the general consensus is the 28.8s are marginal for his setup?
I'm putting together a similar setup with a little less cam and inches.
Mines in a 280Z btw

Sorry to threadjack...
I have mildly ported 241s, 228R cam, LS6 intake, long tubes with a true dual 2.5" exhaust.
I guess I'll see what the duty cycle is on the stock injectors are when it's tuned.
