I am currently putting a turbo my TC I plan to run about 12-14psi on the stock block. I have a question for the ZPI or Dezod guys. Did you guys have to change the head gasket (if they make one) or put ARP bolts or did you leave this stock. I know you guys are running this kind of boost I would appreciate any help you can give me so I don’t have to go on the mission if it blows, I can just do it now while it is apart.

Thanks

We did not replace the HG. I would recommend making sure your tuning is good for that boost.

No prob. I mean great tuning with a good EMS. No BS. Let me know if you need anything else. If you can get someone to make one for ya in advance. Swap it out then your already prepared ya know?

Yeah I was wondering about upgrading to ARP headstuds when adding a turbo. I know when I had my EVO they recommended ARP headstuds when turning up the boost, so would it be a good idea on the tC?

On race gas I assume.

That and/or lower compression pistons.
