2005 Twin Turbo GTO


Created by JavaScript Slideshow Maker

This was my twin turbo GTO project. Bought new in 2005, it came with the 400 HP LS2 and a 4L65E automatic trans. I added the sport appearance package (vents in the nose). I also swapped the factory 18" wheels for Budnik 5 spoke wheels with clear ceramic coating; this eliminates the needs for polishing, they are cleaned with simple soap and water. This was a true rain or shine daily driver.

The twin turbo kit I purchased came from APS in Australia. I am very impressed with the quality of the parts and welding. I got the first kit shipped to the US, and had them upgrade to larger GT3082 turbos, since I was going to use a custom turbo specific engine (402 cid). One of the things I really liked about this kit was the low mounted turbos. If you look carefully you can just see the drivers side turbo in this pic. Completely hidden and all the extra heat is under the car, instead of in the engine compartment. Also the placement and size of the turbos gives instant boost without lag.

The stock LS2 was pulled and set aside. I had Wheel to Wheel in Michigan handle the long block build. It's a 402 cid stroker, 7.9:1 compression, custom turbo roller cam, Callies crank, Howards rods, Mahle pistons. Topped it off with ported 11 degree ET Performance 240cc heads.

With power levels in the 750-800 rwhp range, the trans and rear end/stub shafts/driveshaft all had to be upgraded. Dr. Evil built the trans, and Harrop supplied the rear cover/brace. Billet stub shafts and aftermarket axles and 4" driveshaft were installed. Nitto drag radials were used out back with standard Nitto's up front. The Nitto drag radials do well in the wet also.

The interior was left mostly stock other than some extra gauges. The factory blue leather seats are incredibly comfy for long drives. These cars are a ball to drive, very quiet, comfortable, no rattles or squeeks.
