This was my daily driver twin turbo GTO project. It came with the 400 HP LS2 and an automatic trans. Initial plans called for twin turbos on the stock engine. Later I will build a dedicated turbo motor and up the boost.

The twin turbo kit is from APS. I am very impressed with the quality of the parts and welding.

I built the short block and 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. Top it off with ported ET 240cc heads.
