Oil had been getting into the cylinders previously so a little more should
not hurt. Prestone air intake cleaner was ment to spray into the intake so
that should not hurt (like old carb cleaner). I would change the oil
afterwards but I am sure you would of done that anyway.
Regarding the Garrett Info: here is another Mitsubishi Performance link that
might help I know they rebuild with Garrett wheels.

This Person used Mostly Mitsubishi Heavy industries parts.

I have heard of extrude honed Exhaust manifolds, porting exhaust manifolds,
Matching Exhaust to head, Ceramic coated Headers, but not ceramic coated
exhaust manifolds. I can't see how it would hurt. It would certainly look
good. If it is not to expensive try it.
Regarding the fan: I the only time this would help is at Idle. Who needs
cold intake air at Idle? I would try to modify the ductwork on the hood to
grab more air from a lower, more forward position. The force of this air at
speed is much greater than the highest CFM Fan.

Subject: 505 turbo: Garrett TB0327
So I added this weekend a 505 Turbo to the stable. Needs
love and some work on the electricals, but mostly a fix of the turbo.
George Nunez had given me some instructions on how
to remove the turbo and I had also bought the workshop
manual for the N9TE which I got monday. Monday
night I only had a few minutes so I had removed only a
few things like the intercooler. Last night I removed
everything else and the only thing that is holding the
turbo is two bolts on the exhaust manifold (you have
to remove the turbo attached to the manifold) and the
bottom bracket. The seals are bust, and oil has found
it's way up to the intake manifold, and on the other
side, to the flap of the air flow meter. The bearings
dont have any appreciable play, but I will of course
change them.
I've cleaned all the intake parts up to the intake
manifold, but haven't sprayed it nor the throttle body
yet. Is the prestone air intake cleaner a good choice
for this too? Should I remove all of that and clean these
parts individually so as not to have the prestone product
and oil go in the cylinders?
Also, as I will be disassembling the turbo, I will change
like I said the bearings and seals, but even if the wheels
look good, I want to upgrade them if possible. Anybody
knows exactly what turbine this is? The manual says
Inconel with some number (cant remember). How do
I relate that to a Garett part number? And from this
part number, how do I choose a better turbine combination?
I'd like to push more air, and with a better exhaust system,
I believe I could keep the same spin up time. Does anybody
have a Garrett catalog?
Also, while I'm there should I have the exhaust manifold
ceramic coated or even paint it with a ceramic based paint?
I'm hoping this could reduce the temperature a little (I also
plan to install a high cfm fan under the intercooler so it works
better and as a side effect it will keep the turbo cooler by
pushing the heat generated by the exhaust manifold under the
car and combined with a turbo timer would help for a shorter
cool down cycle. I'm also thinking about an oil cooler.
Should the fire rings replaced be? I will replace all the exhaust
gaskets of course.
As a side note, this is a fairly easy engine to work on. Lots
of space around.
