Recently, someone I know built a LSx turbo car. The piping method used puzzled me though. Lets see if I can explain this, because I do not have a picture of the piping under the car.
88mm turbo is on the passenger side, fed directly from the front side of the passenger exhaust manifold.
Now, the driver side exhaust manifold is sealed at the front. It exits out the back side, goes under the engine and transmission, then is welded to the back side of the passenger exhaust manifold. That means the spent gasses from the driver side must go through the passenger side exhaust manifold to reach the hot side of the turbo. All while fighting exhaust gasses from the passenger side exhaust ports.
Won't this be a huge restriction, killing efficiency, all while causing tuning issues? It appears to be a speed density setup, as I have not located a MAF sensor anywhere. Experts chime in please, because I am scratching my head here.
