Fuel Injector Size w/my setup?
Heres what I have. 2002 LS1 stock block internals, FAST 78mm Intake & TB, new fuel rails, F13 cam, Dart 205 out of the box heads, Yeller Terra 1.7 RR’s, ported oil pump, Hooker LT’s, 85mm SLP MAF & lid, Borla CatBack & a 75 dry shot or nitrous. Im gonna put the intake on sometime this week. I have the stock injectors & can get a set of new 36lbs injectors from a friend cheap (hes not gonna use them on his build). With this setup should go ahead and get the 36er’s in there or is that too much? Thanks for suggestions.

Think the Walbro (sp?) 225 pump and 36lbs injectors be ok to run. I dont want i tto go lean but i dont want to wash out the rings. Have no clue to what it will make HP wise to gauge it on till get it started up.

42's ????????? a racetronix kit, and a set of svo 30's will be MORE than enough for up to a 150-175 dry. Ask me how I know.

Is it safe to assume you ran lean? If thats the case, did you have a racetronix setup in your car, or just a walbro in it? I'd be worried about the 42's only because when he is NOT spraying thats an awfully big injector. Im sure you know that a "lazy" injector is not good at all. I'd hate to back off an injector THAT much........ But if 42's worked for you, then

No, my car did not run lean. It was on a dyno, with a wideband with timing at 28*. I had just a Walbro 255lph pump in tank. I ran 42lb (which is 48lb on a LS1) injectors when I had no nitrous on my car and just a 231/237 cam without any problems. 30s would be maxing out with his mods and a 150-175 dry shot. For a 75 dry shot they would be okay.
