stock injectors
what hp are stock 2002 5.3 injectors good to? last time i had my truck on a dyno it put 250hp 265 tq to the wheels and they said the dyno was reading 10% low that day. since then i have probably added 20-25hp, maybe a little more. i will be doing heads and cam sometime this year so i know injectors are in my future, just how far into my future i dont know. thanks

I would start the hunt for new ones at about 415 hp
|
I'm guessing I'm at 310-320 at the wheels and I've been maxing mine out for awhile. Anything over 90% is maxed IMO. I think I'm at 105% haha
|
ok so i should still be ok with stock injectors even after the heads and cam....i am hoping for 400hp with bolt ons, cam and heads on a stock block and bottom end. i dont know if its doable or not but im going to try
|
no way, heads and cam would max yours easy.
|
if you get a cam you should get injectors. Either the 8.1 truck (31lb/hr) or marine (42lb/hr) are direct drop ins. The normal truck injectors are more than enough and can be had roughly $100-120 less than the marines.

what are stock injectors, 24 or 26 right?
