Why do you want new injectors? You wont see a power increase. There should be nothing wrong with what you have... Its not like exhaust or intake....

as long as you're N/A, it will only hurt you to change injectors other than OEM. If you boost, you'll need to upgrade them

Stock injectors are 30lb. I believe that's rated to handle up to 250hp, right guys? So until you go boost you have nothing to gain from upgrading them.

Now a tune on the other hand would go a long way.

alright. i was just curious. i did find some 42lb injectors by bosch, which are typically used for n/a applications but i dont think i will upgrade until i get some boost (which will probably be forever) lol

thanks guys

I was almost in the same boat. I had bought a JRSC w/ BBk and had installed the over-drive crank pulley, but no injectors or anything else. Then when I sold the SC I had to go back in and put my stock pulley back on and buy another belt...$45 freakin dollars for a serpentine belt!!!

your 30 lb/hr injectors are good for about 200 whp, safely. they shouldn't go beyond that.
