Why is no coolant lines for the turbo a plus? Wouldn't you want to keep it cooler to help the center section happier and to keep oil temps and oil breakdown at a minimum?

I will still have an external oil cooler so oil temps will stay happy. I just hate anything that can leak. I know how to properly cool down a turbocharged car, and I'm pretty sure thats why a majority of turbos went with a water cooled center cartridge, to keep hot turbos from congealing the oil in their center section when the oil pressure stops. And its makes it a lot cheaper to replace the turbo, a lot easier to pull it out of the car, and less AN fittings I have to purchase thumbsup

a single big turbo quite commonly is not water-cooled.
the bigger turbo typically spins at much slower rpm than small turbo (ie, 140k vs 80k) while at times moving significantly more CFM.

I figured there was a reason I just didn't get it. Thanks Smile

BUT, your statement above was still right. I just am just being a cheap-skate...yet only on the things that don't cause catastrophic failure if they fail.

err, well, I mean the turbo only, not the wastegate Lol

And I like 'dem CFM's!!
