Sorry for the delay guys. Ths should keep you entertained for a bit.
The engine build:
As usual, the engine was bored out and had steel cylinder liners installed as well as a set of Carrillo connecting rods and CP pistons. All of these parts are proprietary to Heffner Performance. Below are pictures to show the differences between the stock rods and pistons and the Heffner / Carrillo rods and the Heffner / CP pistons:
As well as adding significant strength to the rotating assembly this combination also lowers the compression ratio to get it ready to handle lots of boost.
Once this is done the engine is completely reassembled and installed in the car.

The turbo system:
The turbo system for the most part starts out as high quality stainless steel mandrel bent tubing.
The mandrel bends are then cut, sanded, fit into a fixture and welded together to make the parts.
All parts are TIG welded and filled with argon gas during the welding process which is known as purge welding. Purging the pipes makes a nice looking, strong weld inside and out.

Once the parts are all welded together they get sent out for different treatments.
The cold side piping can be either polished or powdercoated:
The hot side parts are ceramic coated. They can be done in a number of colors. The shiny silver finish is the most common but for this car we decided to do something a little different.
We thought the black finish might suit this car a bit better because it looks a bit more "race car".

Well, the car is complete and on it's way back to California. We had hoped to get this beast to the drag strip before it left but the continuous terrential Florida summer downpours would not allow it. Here is a shot of the completed engine compartment. Alex is in the process of making carbon fiber engine compartment panels for the Superleggera now.
The black finish is the perfect compliment to the Superleggera in my opinion.
We made a few preliminary pulls and then decided to see what it would make on 20 pounds of boost.
Everyone was pretty happy to see this so we unstrapped it and headed out for a drive. This thing is incredibly fun!
We'll stay on Alex to get us some video of this monster in action once it gets home. Thanks for the interest in this build. I hope this was able to provide some useful information.
