does anybody here have a Precision ball bearing, water cooled turbo?

how did you connect the water lines? straight to the main coolant lines? or did you make a separate mini radiator, and resevor w/ a pump? Also it still would need oil lines, correct?

just looking for feedback on these

The amount of heat added to the coolant due to the water cooling of the turbos is absolutely miniscule compared to the heat produced in the motor via combustion, no need whatsoever for a seperate system. You could snag something like a line to run coolant to the throttle body to warm the air for emissions into the turbo(s), although I've never run them on an LS1 so I'm not real up to date on what kind of coolant lines you have available. Doesn't take a lot of flow though.

My Incon TT kit is water cooled.

On the driver's side of the block you'll see hex'd plug somewhere south of spark plug #1.

In place of that plug the Incon kit has a fitting that screws into the block and then you can connect a stainless braided line to the driver's side turbo. From the driver's turbo you then connect a line to the passenger turbo, and after the passenger turbo it goes north and ties into the heater core on the firewall in front of the glove box.

My coolant temps using hptuners looks normal. Great system.

Is there a reason you could not split the post heater core feed like the Incon does to recirculate the post turbo coolant? That would feed the driver's side turbo from the post core coolant, plumb into the pass turbo and then up into the Incon specified location? It would make a mini loop out of the core and the turbos, but still tie into the rest of the original system with the original routing.

core out - driver turbo - pass turbo - core in

The original core in and core outs from and to the engine, respectively, would still remain. It would be even easier if there was only one turbo:

core out - turbo - core in

You wouldn't have to tap anything if that was viable.

so is water cooled worth the extra money?

It definately prolongs bearing life...that's for sure.

It pro-longs ball bearing life. If you stick with a standard journal bearing you don't need it, nor does it come with water cooling.

I'm assuming ball bearing, water cooled is better than the standard journal bearing then?

also on a side note, when I was watching "Horse Power TV" over the weekend, they showed a TT kit for the new mustangs and I swear they said there was "no need to run oil lines"

which really confused me, anybody ever heard of this? Course with that show, take everything with a grain of salt

would taking the coolant lines that run through TB and running them through the water cooled turbo work well?

No. Not enough volume. The Incon kit's plug is a large fitting on the side of the block.
