I personally think the stock head gasket gets the job done. Its going to keep a bolt on style turbo. Probably an 18g, maybe a 20g. It has a big 16g on it now (the factory is a 14b). It has a manual boost controller, probably the simplest device on earth. Right now it is running a blow thru setup with a GM MAF, maf translator, and an apexi air fuel controller. I might ditch the maf setup and go back to a stock one if I have problems with tuning it.
The cars weigh around 3200 from the factory I think. We will remove all the sound deadening and some other BS we don't need. It will look like a street car. I think he plans on retaining the A/C. Yes it will have a CD player. It has an upgraded clutch already, we still might need a better one. The factory clutch would not hold the power.
Heres a good article on crank walk :
