Why buy a new $60K plus vehicle when you can make the one you already own into better than new condition. I started slowly buying the upgrade parts 3 years ago, now it is finally time to start the upgrade project.

New motor going into the prepped frame

Now we have the upgraded motor installed in the frame it is time for the trans.

Since we upgraded the motor performance the stock trans had to go. We went with the John Wood Tow Master to help get the power to the ground.

The frame is now ready to mate back with the body

Body installed and it runs! YEAH! Custom bucket seat for now. Time to start interior.

Nice clean engine bay finally

Nice idle now that the single shot injectors and new motor are in.

B-Quiet Extreme installed now it is time for the carpet.

The carpet is all in. No more Kool Aid stains from the previous owner.

Time to get started on the seats. I sure hope I can do this and did not make a mistake getting the interior shop to install them.

The lower seat frame is almost ready. I had to sand and paint. The joys of a used vehicle you never know what you will find down in the seat.

The front upper frame is ready to be modified. I removed the armrest bracket since I will be installing the 2008 console.

Stereo and Iphone mount installed and boy that was not fun to get the wiring all straight and the dash modified. The backup camera is my favorite feature..

Now it is time to re-locate the drivers side battery.

Time to get started and hopefully this will help get more air to the turbo.

The driver's side battery is finally located on the frame.
