Schwitzer S200 turbo

[1488]

I have a 12mm pump waiting. And I don't really mind about losing the low end torque as this car won't be a daily driver, I just need 30psi or more boost. I'm also planing to try out the quick spoolt trick you can do with twin scroll housings, how it works is that you have a butterfly valve that blocks one side of the housing and opens up as the turbo is spooled up.

I have a Holset HY35 and I can make 18-20 psi by 3500 roughly depending on the gear. It makes 5psi by 2500 and at 3k its making 10psI. I doesn't start to pull harder than the stock turbo till about 27 or 2800. It's basically a turbo off of a newer Dodge Ram Cummins with the 4 inch outlet on the exhaust housing.

That's nice Mojica, I ran about 18 psi with the original turbo and intercooler and I didn't have any problems. But you know the size of the hot side on that HY35 you have?

I cannot for the life of me find out the size of the turbine housing. All I can find is the size of the turbine wheel which I believe is 61 mm.
