Yup, it's a water cooled turbo, but can be run oil cooled only. Leave the water jackets open. Make sure you exercise proper cool-down procedure before shutting off. It'll live.

If you track your car, then run oil through the water jacket too. Just a bit of added insurance.

Our motors idle/run at less oil pressure than Japenese cars, so you don't really need an oil restrictor. Just run a -4AN oil feed, unrestricted. Mine works perfectly. My turbo would tell me if it's getting TOO much oil

I was told by the Garrett distributor that an idle pressure less than 2bar WITH a restrictor will starve the turbo of oil and lead to premature failure. They advised not to run a restrictor. Hope this helps.
