If you are still running your 25 year old TIRED wastegate then you are MOST LIKELY LOSING POWER!
Tial makes a great wastegate for the 944 Turbo. The 38MM Tial F38 out of the box fits in place of the factory 944 turbo wastegate.
The upgrade to the Tial 38mm will require adapter plates to bold correctly to the factory exhaust plumbing.
Fejjj has manufactured a stainless steel adapter plate solution.
The kit includes the two plates, gaskets, and drilled hardware for use with safety wire.
