what is the part number for 60 lb fuel injextors?

do i need headers for a stage 3 upgrade if i have no resonator plus a smaller flex pipe?

will a 2.7 inch fit on the supercharger snout that comes with the car from the dealer?

 

There is so many things wrong with those questions where do i begin . No you dont need a header for stage 3. Gm stage 3 doesnt use 60 lb injectors . And i belive 2.8 is the lowest you can go with out grinding the snout

 

i think a 2.7 is there is a lot of room left on my 2.8

 

I think the 60# injectors require a different harness if I'm not mistaken. Since I haven't bought a set I can't be sure, just things I've read.

The stock pulley on the supercharger doesn't have a hub with bolts on it either so you'll need a hub of some kind to change pulleys after removing the stock pulley.

 

60# injectors will need a new harness.
Part number? Just look the injectors up on OTTperformance.com or something
No header needed, better for breathing, but not needed. But you have a smaller flex pipe? What on your DP?
You will need a new hub for the pulley, look on OTT again for the hub and pulley. I thought the 2.7 you had to grind the snout but not too sure.

If the car is stock, and you want to do all of this, buy the OTT stage 1.

 

We are doing a group buy for 60's from OTT as we speak....great deal!
