Re: Turbo Gaskets?
Thanks for the reply. I was wondering if not installing the gaskets was another red neck repair from the previous owner. I guess I was just fortunate that the bolts were not rused and all came over reletively easily.
As far as porting the DP and crossover pipe, I am not talking about the size of the opening. There was a chunk of the DP that stuck up off of the flange and obstructed flow. Also, where the two sides of the engine exhaust meet, there is a 1/8" gap between them. I grinded the DP imperfection off and grinded the crossover pipe gap down to a knife edge so that the two sides of the exhaust meet smoothly. Today, I will be smoothing out the pipe's edge inside the DP flange to make a smooth transition for the exhaust gas.
When I get to the turbo, I am going to try to smooth out the flow going to the waste gate flapper. I wish GM had joined the exhaust flow from the waste gate with the main flow going through the turbo a better way. The exhaust has to take a 90* turn to go out the waste gate flapper and then another 90* to get back to the main exhaust flow and another 90* turn to join the exhaust flow. Instead of welding the original hole for the bypassed gas shut, they should have extended the DP to cover that area and make a smooth transition back into the exhaust flow. I'm tempted to cut the weld out and make a dump tube. Too bad I live in Kalifornia and that would get me a very hefty fine.
