I'm giong crazy trying to decide if i can do both. I'm coming to the conclusion that you can either do one or the other. I fyou want to go v-tec you need higher compersion pistons. If you want to go turbo you need low compersion pistons. I don't know how to make it work so you get the best out of both. I don't think its possible. help!!!!!!!!!!!!!!!!!!!!!! I'm think i'm just going to go for ls/turbo
