Ok, I'm getting my hands on a 85 K20 with a 6.2. It has 97,000 miles and has been serviced at dealer since purchase. Best part is if I told you the price I'm getting it for, you'd die /forums/images/icons/smile.gif Anyway. I wanna plan this out. So I need to know EXACTLY what parts I will need. As I understand it. Its recommended to use a manifold off a 6.5 in the 93 model year. as well as the Turbo. What else will I actually need to do. The truck has A/C so I understand theres clearance problems with something. Can someone run the process through me. I'm not a Noob when it comes to Working on trucks. i'm just a noob when it comes to Diesels. This will be my first.
