Herman was very helpful and now my 93 945T is boosting as it should. After I rebuilt it he balanced it on his fantastic Italian balancer. Next car I would like to go for a hybrid ported and polished turbo.

He also suggested replacing the PCV box under the intake manifold which reduced oil cap jiggle, and according to Herman saves the turbo from premature carbon build up.



Other mods:

Removed air box and gutted it, next I need a K&N filter or may switch to a cone filter.

My Cat. was clogged so I reamed I out, interesting sound- pinging thundering tone the hot exhaust bouncing around the empty Cat. Also new exhaust with straight tail pipe.

Cleaned out my intercooler had oil deposits.

New Borbet wheels with Summitomo tires.

Lower temp thermostat.

Cleaned out my idle air control valve, and throttle body.

New plugs, timing belt water pump and belts.

Waiting for my Dawes device, looking at the new Cartech rising rate fuel pressure regulator.

Any other ideas that woul be resonable and worth it???
