So I have an early 99 rcsb and ran across a set of stg 1 injectors(180cc). They have about 150 miles on em. He's upgrading to some stage 3's with his tax return. Lol. I also bought an 01 parts truck with a new turbo. So I was considering swapping to the 99.5+ turbo. My question is what all should I replace while swapping?
