I have a rebuilt IHI VJ-11 turbo here off a Mazda MX6 that I am looking to install on my Mazda Miata 1.6 DOHC, what is the danger of blocking off the coolant/water lines with bolts and running the turbo as oil cooled only.

I dont have the water lines/fittings/banjo bolts etc for the turbo currently and really dont want to bother with them if possible.

Your input is welcome.

 

answered at m.net.... dont cross post.

 

What is wrong with asking the same question on 2 different Miata forums? It is not like I am posting twice in different groups on the same forum?

Would you not ask 2 different mechanics about an issue you were having on your car for instance? I am not trying to be rude, just asking.

 

Some of the forum members are currently running water/oil cooled turbos with the water lines disconnected without any issues but I would suggest you think about connecting those water lines whenever you get a chance.
