Well, if you can't help me then I may just do it myself and have some help from Shawn and others. He has a friend who can do the aluminum welding, I just need help with clocking the w/g actuator bracket.



Are you sure you don't have a small oil leak that may be dripping oil on your hot exhaust manifold or turbine housing? That would cause it as well.

no oil leak at all. I used to have one with the RB adaptor, but it's been pulled off the car, and there's no oil on the floor in my garage even after it's sat around for days. The smoke doesn't come out right away or anything either. It takes a bit at idle before it starts. Once I start driving it's gone and usually doesn't return.

Yeah, I've been there and done that several times with both turbos.
It is a result of the outrageous heat soak that the bearings must withstand having the turbo positioned where it is.

Its embarrassing. You are sitting there at a long traffic light and everything is fine.
Then, suddenly, there is a massive cloud building.
Then, it goes away and doesn't happen again for a few hours, days or even weeks.

Cool. You'll get it done a lot sooner that way.
I don't even have time to do my own conversion until the spring.

so does that mean my bearings need to be replaced? or is this just a cooling issue?

Probably both.

The turbo is in a crappy location sitting down there in the first place, which lends itself to getting your bearing cooked because of the high heat.

That's yet another plus the Garrett GT2871R; it's water cooled, so you have coolant helping to keep the CHRA cool.

Sometime next year I may experiment with installing some kind of duct or panel to direct more airflow to the turbo or evacuate more air from the turbo area.

Probably the bearings.
Just pull the downpipe and give the turbine shaft a wiggle.
If it moves more than .5mm or so all the way around, they are done.
It'll probably more a lot more than that.

Wait a minute.

How are you going to bolt a Garrett turbo to a Mitsubishi manifold?

MazdaManiac

Because it is a T-25 style inlet, common to both and the discharge is a standard 5-bolt outlet.

your say the bearings are easy to replace?
ive been looking around for replacment bearings for my greddy turbo and havent found any yet.
where might i find them?

MazdaManiac

A turbo rebuild shop should have them.
There are three shops right here in Phoenix that have them behind the counter.
Its about $20.

There is nothing wrong with Wisconsin. Well, maybe.
There should be a turbo shop somewhere.
