wats the story wit turbos that are only cooled wit oil?are they any good??
if ya were to use one on an sr could ya jus block off the water feeds for coolant lines on the block??

Yup water/coolant feeds can be removed, think ya need an oilcooler first tho

A turbo has to have a wastegate, it can be internal or external.

Larger turbo's will run an external wastegate simple because the diameter needed wouldn't fit in the turbo housing. Externally wastegated turbo are also more flow efficient as they don't have an internal wastegate upsetting flow when its closed.

With regards to water cooling.the theory is it can be removed from any turbo once the car is running an oil cooler as for track use a water cooled turbo can have an adverse effect on water temps but I wouldn't recomment it on any turbo other then ballbearing.

Your turbo would be internally wastegated dara cos, its the actuator that controlls it opening and closing in the exhaust housing. Go for external gated turbo if ya have the choice....oh the noise!!!lol!

This is what they look like:

Yea you'll need a manifold with a flange for the waste gate 2of then a dump tube to run off it. Ebay ones are cheap for a reason Tial 38mm ones are good and not too dear.
