Are you constantly on here via your phone? I don't think I've ever seen you use punctuation...

Default You will see some gains with a hybrid, but yea, Mental nailed it. The hotside of a k04 is the
limiting factor.

Default Re: Save your money
Theres no cost effective way to modify the PJK04S plus the hot side is way to so. Just step up to something larger..

Default I'm not sure it's worth the trouble. Only do it if you have a very trustworthy shop doing the work..
Some seem to have seen a nice bump in airflow up top after clearancin the hot side of the turbo.

Clearancing is done to the exhaust housing aka "hot side" and consists of increasing the gap between the exhaust wheel and the housing.

Stolen from a post by Jacob Buehn, who used to be a big contributor here and built, rebuilt, and modified turbos for folks including myself:

"Clearancing is one way to allow excess exhaust gas to bypass going through the turbine wheel and lower backed up pressure in the turbine housing."
