They are excellent but very backed up with work as well. I know a few people who have had cars there for over 2 years and still don't have their cars finished.

Happy with my 4.0 build from Jeff @ Kraftwerks Performance, but as others have shared, there will be a wait - as seems most / all air cooled shops have long build queues.

Jae Lee (Mirage International) or William Knight (Knight Race).

Go with Jae Lee. He's built an air-cool 4.5L for his street/track car and was original engine builder for Singer.

Be prepared for integration challenges, for a 4.0 you'll need a new ECU and that will not be simple / easy / fully integrated into the 993 90's electronics / security.
