Hot Side Pipes are Done

Finished cutting the pipe for my hot side. These will relocate the turbos and give me much more room under the hood, as well as allow me to run a front mount radiator and have shorter downpipes. They are not the same length on the long leg as the headers are different lengths in relation to the position of the outlet.

Gen 4 bottom end with rods and pistons removed.

 

I finally had time to get the Gen 4 5.3 torn down. I removed the rods and pistons to open up the ring gap. Stock ring gap was anywhere between .015″ to .017″, not exceeding .017″ on any of the cylinders. Only the upper ring gap was modified. It was opened up to .028″ to .030″.
