I have a put a 1GGTE (gen 3) in a XA6X celica and have recently bought a HKS single turbo kit for it. Before I put the single kit on, I would like to do an egine rebuild. I was wondering if other people have done rebuilds on these engines? Where can you source the parts (head gaskets, rings, etc) from? and are there any performance parts that anyone can recommend? Your help would be greatly appreciated!!
