Hey I’m new at swapping engines and I had my em2 for quite a while now an I have being wanting to k-what it. As of right now it has the original engine that currently has a blown head gasket and it’s auto. All I have bought for now is the rsx sub, and the clutch reservoir. I wanted to ask if by buying the k-tuned level4 kit is worth it or no? What else can I buy? Need?
