My water lines are running from the throttle body coolant lines. Haven't had an issues that I know of. My stock oil cooler is still in place with the Mase kit

 

Thanks for correcting me, sorry for the misinformation... I was under the impression they had to be connected to cool the bearings properly, guess not I'm still learning the ins and out's of turbo's had always ran SC's in the past. Turbo's are SOOO much better though

 

That's the way I'm currently running mine also, although I'll be switching to the oil cooler feeds very soon most likely. FYI I noticed after melting two turbo coolant lines, the blue thermal intake manifold gasket I installed blocks off the water flow to/from the 1/4" hole in the side of the Cyl. head that feeds that TB coolant line thats in front of the air bleed screw. I had to drill a hole in the gasket, just something to be mindful of if your running one of those blue plastic thermal isolation gaskets.

 

I am running the Hondata intake manifold gasket and I have coolant flowing out of the lines as designed. Which one do you have?

 

I purchased an alum radiator, and welded 2 bungs, one top, and one bottom.

Ran the lines, and it not only looks clean, but keeps my temp in check.

 

 

Also from their website:

Garrett ball bearing turbochargers require less oil than journal bearing turbos. Therefore an oil inlet restrictor is recommended if you have oil pressure over about 60 psig. The oil outlet should be plumbed to the oil pan above the oil level (for wet sump systems). Since the oil drain is gravity fed, it is important that the oil outlet points downward, and that the drain tube does not become horizontal or go “uphill” at any point.

Following a hot shutdown of a turbocharger, heat soak begins. This means that the heat in the head, exhaust manifold, and turbine housing finds it way to the turbo’s center housing, raising its temperature. These extreme temperatures in the center housing can result in oil coking.

To minimize the effects of heat soak-back, water-cooled center housings were introduced. These use coolant from the engine to act as a heat sink after engine shutdown, preventing the oil from coking. The water lines utilize a thermal siphon effect to reduce the peak heat soak-back temperature after engine shut down. The layout of the pipes should minimize peaks and troughs with the (cool) water inlet on the low side. To help this along, it is advantageous to tilt the turbocharger about 25° about the axis of shaft rotation.

Many Garrett turbos are water-cooled for enhanced durability.

So, the water cooling is a passive solution to prevent oil coking instead of having a turbo timer keep the motor idling after shutoff. (Or just driving gently for a bit before shutting down.)

 

You may need a Aluminum pump instead of a plastic bosh pump.


Try CSR or was it RCS pump expensive but way better then the bosh pump


If it was me I would do two turbo timers one to run the car for 5 min for first cool down then a second that runs once the motor is off to keep the water pump running for another 5 min.


In addition to that would have a reservoir in the feed system to increase the hot flow (thermal flow) effect even after all the turbo timers are shut off.
