Think again. This is what happens when you put a Chinese Holset copy on a dyno. http://www.youtube.com/watch?v=Za0DieZHMKc

Boost leak.

People who try to eat my lunch better be able to run faster than 1150 fps.

If your oil pressure is above 40-45 at idle, and more than 75 or so at WOT, it needs some sort of restriction. Hitachi never designed the ct26 to run more than 45psi at WOT.

Most of the Holsets are part balanced.... The comp wheel and turbine wheel & shaft are balanced separate. You should be able to rebuild any Holset without having the entire assembly sent out IF the wheels do not have damage or rub marks in the housing(s).

Yes. Drain must be no smaller than -10 and MUST flow as straight as possible.

Run it. If the crack(s) are less than .5mm in width, run it. Cracks in the turbine housing wastegate area will eventually cause the turbo to spool sluggishly and if the cracks become pieces of housing, the turbo will self destruct.

The ct26 (hitachi) cartridge DOES NOT HAVE AN INTERNAL OIL RESTRICTION. The subaru turbos (mitsubishi) do. Thus, they can run over 90psi most of the time. The ct will leak oil above and beyond 45psi with out seeing boost in the compressor housing.

He said turbocharger, not dinosaur.

Done.

No prob. Trying to keep you guys safe. And for some of the other questions, DO NOT EVER TWIST OR CROSS YOUR BELTS. Nylon + nylon + 10g impact = BURNT NYLON = DEAD YOU. :icon_evil

You're not retarded. Retarded would be putting a wastegate signal port in your exhaust. The "correct" answer, so that you don't see boost creep or spike - see below. Ed has it right. :icon_bigg

Hold your tongue kind sir. The OP asked an elementary question, therefore he received an elementary answer. This is correct. I have seen, on many accounts, odd and unaccountable wastegate problems due to the fact that the signal port, or "nipple" was not before the throttle body, AND...

Im reading a lot of mindless dribble here in this thread, and most of it could get some one killed. Your harness bar needs to be welded or bolted into a MINIMUM OF 4 MAIN CHASSIS POINTS. Four great points would be the rear bottom and front side seat belt bolting / anchor points. This harness...

Giant loaded question right there Jeff. 1.) You need to do some searching, as I see you have a whopping 2 posts. 2.) To actually answer this question, you need to tell us what is done to the engine, what ECU system you're running, etc etc etc etc.

^ Correct. Nipple can be any where after the turbo, but BEFORE THE ENTRANCE of the intercooler.

Who here is good with taking a photograph and making it into an outline aka line art. Black and white line art. Let me know.

Check out s&w roll cages for well in parts.

Too much pron. *EDIT* some one beat me to it.
