My experience with Performance was mixed.

 

The good:

1.) contact with sales (Stuart) was pleasant and prompt before the sale.

2.) the price was quite competitive.

3.) the sales contract was clear and complete.

4.) the engine arrived in good condition

5.) at 300 hrs the engine is running smooth and never needed GAMIjectors

6.) refund sent for the returned A/C bracket (see #3 below)

7.) agreed to work on the engine at no charge (see #4 below)

8.) repaired and return-shipped a cylinder at no charge (see #5 below)

 

The bad:

1.) the turbo oil sump was not installed and had to be shipped later.

2.) 2 psi oil pressure traced to an installed bent pressure valve.

3.) jury-rigged bracket for the A/C was not usuable.

4.) starter adapter leakage required the engine (plane attached) to be returned for work (see #3 below).

5.) lost an exhaust valve seat at 200 hrs.

 

The ugly:

1.) as problems arose Performance stopped returning phone calls and e-mails.

2.) engine shipped 5 months late.

3.) I was told the engine was crated but would not ship until I wired the final payment to their bank.  I did so, and the engine still did not ship.  A fellow builder visited Performance 3 weeks later and discovered that my engine was still in the building process (where it remained for months more).

4.) while doing maintenance on the engine Performance caused a fire that burned the air conditioner and into the aft bulkhead, smoke-damaged the interior, and required the avionics be RTV for inspection and repair. This $30k insurance claim caused a rate increase. 

 

So in summary although the engine seems to be fine I would not again go through the irritation.
