ok reacently acouple of us 2.4s are going s/c so i figure we help eaother out soo Q num 1 do wee need a lsj fuel rail????

 

Nope just bigger injectors

 

stage 2 injectors work?

 

you need EV6 injectors, the LSJ uses GM mini connectors and normally gets upgraded to EV1. For a supercharged kit you can keep the stock 2.4 harness and run either 33# (for low boost) or 39# for higher boost here:

i have IDCs in the 80s on a stock pulley. 42s second-hand are plenty...if you don't want to dick around with clips then get the 39s. plug and play.

 

well ott is installing it soo i wouldnt need to mess with it but they said it would be best just to run 42s
