If you are willing to ship the motor, I've only got one machinist/engine builder that I would trust with a Supra motor at this point.
Bryan Maloof Racing Inc
[strike]2860 Buford Highway Suite D, Duluth, GA 30096
Phone: (770) 622-4979[/strike]
Edit: Bryan has moved, new contact info:
1316 Robertson Loop Road,
Clarkesville, GA 30523
Phone: (706) 839-1550
This man has incredible attention to detail and he doesn't need any "coaching" to get the job done right. In the 20+ years I've been building & racing cars, I have never found a better machinist/engine builder.
Bryan is familar with the JZ & M series Toyota motors and has built a ton of them.
I can't say enough about the quality of his work or his professional integrity.
