quote"They where here @ our shop the weekend of the War of the Imports and we told them that they were getting the oil feed from the wrong spot!

The EVO's have Oil/Lubrication problem from where they are getting the oil feed, which is in front of the head. Thats the last place on those motor to get oil, we check on our "Eligal EVO" and on that spot @ high RPM gets about 30-35psi of oil pressure!!!
Everybody knows that @ 9,000+RPM and @ 40+psi NO turbo is going to hold with 30-35 psi of oil pressure!!! "

I would elaborate alot more on what we think is the issue but as i promised bullseye i would not post anything else til they looked at the turbo and gave me their input..

BB turbos do not require much more than 20psi of pressure IMO.. A very well known builder/tuner has assured me feedling the turbo from the head is no issue on my new setup..

Yeah, the BB turbo doesn't require much oil at all, so if it was an oil issue, it would not show itself with the Garrett like it did with the journal bearing BW. For what it's worth, i run my turbo with a -4 feed line from the block and run about 85psi oil pressure.

ill pm you with some information as well..

I'm only trying to help, making more power at less boost is better all the way around.

I didn't read it all, but what were the details on the 372 (turbine housing and manifold) and on the 4202? I think i read that you changed the manifold setup with the 4202?

I have seen HUGE differences in power with different manifold/turbine a/r's. The common mistake everyone seems to make is a big compressor and choking the turbine size down too far because they're concerned with spool. Too small of an a/r will kill the VE of the engine and result in very high boost levels for the power being made.

Don't take any of this the wrong way, i'm not attacking you or telling you you're doing it wrong, just sharing what i've found in hopes of making your situation better in the future.

Hope you get everything resolve soon Mike@USP!!!
The car is sick !!!!
