I'm sure people have thought of this before, but wouldn't a seperate oil supply systme for the turbochargers keep the turbos cleaner and give them a longer life span. If you had two oil pans, a larger one and a smaller one for the turbos then none of the dirty oil that is used in combustion would touch the turbos, thus keeping them cleaner, giving them a longer life span, and you would probably not have to change the oil as often. It's probably not worht it for the extra weight and equipment but just an idea.

 

I agree, and am also wondering. I know that someone posted here a year ago or so about a custom TT kit with sep. oil system.

 

This would present a bunch of challeneges. You would first need a separate tank for the oil. Then you would have to run an electric oilpump and plumb in a filter. If the electric pump failed, your turbos would be toast. Lastly, where the hell would all this stuff go? There's so little room already in the engine bay.

 

That's a solution to a problem that doesn't exist.

Change your oil and filter on a regualr basis, consistantly allow a cool-down cycle, and you should have no problem getting 250K from any good quality turbo.

If it ain't broke, don't fix it.
