Injectors My friend has a 2000 Mustang GT with Fordracing 30lb/hour red top injectors that hes selling.
Are these the same injectors that fit on the LS1?
The part # for Fordracing red tops for an LS1 is M-9593-B302...Im just not sure if the injectors he has are the same thing.. But I think they are, arent they?

Personally I wouldn't bother changing the injectors such a small amount weather they fit or not.
Depending of the year of the LS1 you could have 26 or 28 lb/hr injectors.
If you changed to 30's it would be such a small amount the fuel trims could tune this with no PCM reflashing, would need to verify WOT though. If I was offered 42's then that may be worth considering.
Unless you do mods that will bring in more air into the engine then injectors dont need to be changed anyway, it wont offer any performance increase. The stock ones I beleive can run 400-450bhp, although its nicer to have larger injectors so you have a little play in them not maxing out.

I use those and they are good to +/- 500rwhp on stock system and about 550 on my system (255 pump with harness and regualtor at rail 62 psi)
