Yea but the tuning should effect the boost really, I have my wastgate closed off it should be building lots of boost like thatassuming no boost leaks, im going to put the maf up front and run the motor na but with the turbo still on the exhaust, cap off the charge piping and measure the pressure that the turbo can produce like that. that should tell me if there is something wrong with the turbo, if it does make good pressure then I can narrow the problems to either possible boost leaks, or the turbo just doesnt flow enough on that motor to build pressure. Ill let everyone know how it goes.

 

It would not necessarily be worse for boost and flow. If you have a 2.5" round pipe that you want to replace with oval, use an oval pipe that's say, 3.5" wide and 1.75" tall (just as an example - I didn't actually calculate the volume but just threw the numbers out there for the sake of the argument). That way, you'd have a wider width but a lower "height" to the pipe. If you size it correctly, you could have the same flow volume.

 

sorry to bump an old thread, but that looks like a Gm-8 turbo, made by IHI for GM on their 6.5L turbodiesels from the mid to late 90s.
