sorry if this is a dumb question i searched around but couldnt find anything

i was wondering where you buy the stage 1 and 2 kits?
also do you need to get stage 1 before you get stage 2?

thanks

I bought mine from the dealer the same day I bought my car. I bought stage 2 - I never heard of stage 1.

Crateenginedepot.com is where you can buy them but i suggest ordering them from the dealership so there are no warranty issues. Some GM guys are hesitant about installing parts that they didn't order.

Also;

Stage 1= Bigger injectors, ECU reflash

Stage 2= Bigger injectors, ECU reflash, smaller pulley, tighter belt

So, stage 2 includes the original stage 1. So you only have to buy stage 2 to get all the parts.

I have the stage 1 injectors but I dont even know how big they are. Does anybody know how big they are compared to stock ones?
