oh thank you for the pictures. that helps me out a lot.
 
i also was wondering the same thing
 
No leaks at all. My friend hammered the crap out of it, 0 leaks tested !
 
Very nice way to do. I just JB weld it, not the kwik, the legit JB weld. Hasn't leak so far! :hellyeah:
 
You should be ok from the ofh. Mitsu turbos are journal bearing type. Ball bearing turbos need to be fed from head or restricted from the ofh. Mitsu has a restriction of sorts built into their turbos.
Not true in the least. Your assumption is the reason I get a few MHI turbos per month in at my shop with no shaft play at all, yet have oil gushing from the turbine seal.

There is no restrictor in a MHI turbo. When you look into the hole you'll see three oiling holes- only one of which is visible when peering straight into the hole (the compressor-side journal hole). Two of the holes feed the journals, the largest of the three leads to the thrust plate. Sure the journal oiling holes are smaller in the MHI center housing; this is because the turbo requires less oil volume than it's Garrett T3 counterpart.

How do I know the turbo itself does not contain the restrictor? Look at the 1G oil feed line from the head....the banjo end at the turbo contains a .070" restrictor:

At the head:

Wouldn't you think if the turbo itself had a restrictor that restricting the line would be pointless?

In addition, why does swapping the feed line on a turbo that came from the factory fed from the head with a restrictor built into the line to a setup that comes from a source with three times the pressure and six times the volume sound like a good idea?

People cannot get it straight with this. Use a 1g oil feed for a td05h turbo. Mitsubishi engineers solved this question years ago. I have run evo3's, and 20g's like this and never had a problem with the 1g oil feed. I bought a galant vr4 with a brand new mhi 16g fed from the ofh. After about 5000 miles it was trashed. The car also had a bse.
 
Ok so if I feed it from the head with a 1g feed line, do I have to
Pop the valve cover and clean out some
Sludge like someone had suggested earlier?
 
If there will be any sludge, it will be laying in the front oil galley visible after you've removed the plug on the front passenger's side of the head. You should clean this area the best you can with Brake Cleaner / Starting Fluid / Gum Cutter, then change your oil and filter shortly after doing so (within a couple hundred miles).

This is only for guys using the head feed for the first time on a car that's had the head feed capped it's entire life.

Got it! Thanks Jus!
