06 TRed GTO

I will be installing a new cam (218/222) and LT's with no cats with a new trans with a 3000 stall.
My question is what size injectors come on this truck (2002 5.3L) stock. and with my mods listed above will I need bigger injectors? if so what size will I need?

I am hoping for around 315 RWHP after everything is done the last time on the dyno it did 279/298 so I think its very possable to reach my goal

you probably won't need new injectors with your 2k2 although it wouldn't hurt. It's kinda a hit or miss. They come with I believe 24lbs injectors. The 99's and early 00's had 21 lbs injectors and those max out quick with mods.

Just run some 30 pound injectors off an 8.1L engine.

start out with those 24#'s and log your injector duty cycle.
i know mine were maxed out at 110% with my 220 cam.

Will reg (LS1) style 44lbs injectors fit the truck, I have some from my maggie when I go to 60lbs injectors

no there are a different connector.
315hp sounds kinda high...probably shoot for jsut udner 300...unless ur tuner tricks the dyno jsut for the #'s

my truck is at 280 now I think a cam and Long tube's should easly take me to over 300

yah....what does it do in the 1/4 mile thats the real test.

I can make tons of HP on a dyno, but its niether usuable or reliable or actual...

BTW...i love both colors on ur gto and truck...drooool
