I had mine rebuilt by the Maestro
 

My '67 912 Targa detonated one night after a easy 5th to 4th downshift onto an exit ramp. The crank, weak because some fool previously fitted a turbo to it and stressed the engine, shattered and exited the case. Ugly, very ugly.

After searching, reading, and talking to others that had rebuilds done, I picked The Maestro, aka Harry Pellow (www.hcpresearch.com).

No, it wasn't cheap, but I know I have a solid, dependable engine that will happily carry me many miles. The Maestro was a pleasure to work with, and he really knows and loves his work. I can't recommend him highly enough.

If you plan to keep your car, and drive it daily, contact the Maestro.

Hmmmm did you happen to take any pics of the engine with the Turbo on it? I would love to see that.

I agree, the Maestro is a gentleman and probably the greatest font of 356/912 knowledge alive. He took two basket case engines of mine and I came away with the sweetest running, sweetest sounding air cooled engine I have ever seen. Yes, it comes with a price, but as they say you get what you pay for. Some say he is overpriced but anyone in business for themselves knows that you have to make a profit, knowledge comes with a price, so I now have the confidence that it was done right. My humble thanks Maestro! PS... The engine is a work of art!
