...with all this I hear about turbine housings being too small on most easy to find, cheap turbos, I'm curious what you guys might think of an H1C or similar setup? Simple and easy to work with...easy to match flanges and they're a "dry" turbo (I think that's the propper term...only have oil running through them)...and they're cheap. Lots of holesets on Ebay for under $100.

Opinions?

 

...bahahaha...or a TE0644...lol...there's one on ebay right now for $46...

 

I would consider that a disadvantage.

 

I'm still not real sure as to how watercooling effects them other than to keep temps down in high-stress situations, but I know that the motors that these come off of are under far more stress through out their life than what the average rotary should see. But, again, still learning...I was looking at it as an added simplicity...not that running coolant to a turbo is difficult. I just like looking at the cheap options out there.

 

The only reason water's there is to keep the oil inside the turbo from coking due to overheating.

As long as you time your engine (turbo timer), and have a good oil cooler, you're good to go.

 

Don't FC's have a really good oil cooler?

 

yes

 

Water-cooling means the core runs at lower temps and hence lasts longer. A turbo timer only helps at shut-down. It doesn't do squat when the turbo's actually being used.

I'm not saying water cooling is strictly necessary, just pointing out that the lack of it is not an advantage, which was implied in the first post.
