You can't use the NT waterpipe unless you are not running coolant through your turbo anymore. There is no provision on it to feed the turbo coolant via that horseshoe shapped pipe that goes from the crossover pipe to the front of the turbo. You don't actually need to run the coolant to the turbo but that is a choice you'll have to make.

How about the 1990 turbo water pipe?

yes, that is what you want. it has no outlet for the oil cooler, but does have a port for the turbo.

I looked at a junked Galant LS (auto) t-stat housing today with the intention of pulling it, but it looked totally different. Instead I came back with a pocketfull of nuts and bolts, fasteners, two trunk fender liners and the charcoal canister bracket for my catchcan.

Back to this thread.

All oil cooler parts have been ordered. I went with a 13-row Mocal oil cooler and -8AN lines and fittings. I'm going to mod the filter housing soon, as we'll be pulling the balance shafts at the same time. How much should I open that port up in order to drop my oil pressure a bit? Finger sized?

One last question. I plan to loop the coolant hoses at the thermostat housing. Which water pipe do I need (final answer!)? The engine will be OUT of the car for all this during Memorial Day weekend, and timing belt, water pump...

If you are using a watercooled turbo then you need a 1990 pipe. Otherwise a NT pipe would be best. I opened the port up on mine to about 1/2" if I remember correctly, once you pull the piston out you'll see how big it is and how big you can go with it. Remember to de-burr the inside of the hole so the piston doesn't get stuck open .

Reading on "another" site yesterday and you really can't make the hole to big, within reason. Some used a 9/32" drillbit, others used 11/32" drill bit, and some use a Dremel like me. Here is the link with pics that has been whored around everywhere.

As for the water pipe, it makes sense to me to use a 90 water pipe. Since those were the only ones that didn't use the water/oil cooler. I personally didn't have my motor out (and didnt care to pull the water pipe) so I just looped the lines under the car with a short section of hose.

You'll need a '90 TURBO water pipe if you plan on using the drain/supply from the pipe and thermo housing. You then won't be able to "loop" the lines and you'll just have to cap off the port on the thermostat housing.

Alright, thanks fellas. 1990 water pipe since I always plan to use a water cooled turbo. And I'm going to attack that filter housing with my die grinder and carbide bit tonight

I remember Powerplay having very high oil pressure when he added all these parts to his car last year. I wonder if he ever fixed it to bring it down...

Of course! I even posted a picture of the port after it was done. My oil pressure is a constant 60-70 lbs now.
BTW, when I did the '90 filter housing, I had Alex just weld up the port for the coolant line. Easy, no problems and I didn't have to find a replacement.

Depending on how much the 1990 pipe costs, I may just JB Weld it while we're installing all this stuff. I'm trying to find your thread right now with the picture...

so is it a necessity to run coolant through the mitsu turbs?

I saw this and thought it was interesting:

Sleepy, I just ran across a post on here yesterday where several people had said they weren't running water through their water cooled turbos. Let me see if I can remember what thread it was in....

IMHO no, as long as you turbo time it. When I put the Evo8 turbo on the Mighty Max I'm not going to bother with the liquid cooling.

I just spoke with Mike, one of the turbo techs at forced performance. He told me Mitsu put the water lines to the turb as added insurance against people who don't time their turbs. He said the b16g they sell with the dry cartridge was identical oil passages to the other td05 turbs. The water serves no "real" purpose, but make sure you have adequate clean oil, and practice proper shut down intervals.

Yes, my son, you are reading about my next elimination. This will make turb swaps and other jobs much simpler from here on out.

Anyone selling an NT water line? PM me please.

I'd suspect that you want to make sure you upgrade the stock oil cooler if you do that. The oil is going to be responsible for handling a lot of extra heat that was dissipated through the radiator when the turbo was water cooled.

External oil cooler going on in the next few weeks. I'm keeping the water lines until it's proven by someone here running the car REALLY HOT that the turbo won't get cooked without them.

Their turbos *ARE* water cooled -- and they have an external oil cooler (not sure if that's more efficient than the coolant one on the later models).

My freind auto crosses his 18g with no water lines, never has any problems. He ran his 14b like that for a year as well. Never had an issue, he installed a turbo timer at the same time though. fwiw

Keep in mind that all of the reports of usage without water lines is for very short periods of time. Who knows if the turbos will still last as long. After all, the water lines are there for a reason.

Any external cooler has to be better than the tiny sandwich fitting.

all of this is relevant. Cy is installing an oil cooler because it's a good idea for his application (ie road racing). I daily drive my pos, and almost never get into boost (well, boost under load. W/ the gm maf in blow through and my free flowing setup it's ALWAYS around 0-5psi). I make a few passes at the track once or twice a month with a 14b. It's a cheap replacement. I have 3 lying around in good shape. Think about the guys with a large ass turbo, no water lines, more heat, no air/air cooler.

I know a guy who eliminated the oil cooler on a 90 and didn't switch to a water cooled oil filter housing and the car still runs great. No turb problems. Now that's real.
