I'm gonna take a trip to the scrappers at the weekend and see if I can spot anything that will do the job. The S2 turbo unit doesn't have the fins for cooling like the series 1 so it will need the water supply to help keep it cool. I know people run the turbo's without the water supply but I'd of thought that would do damage in the long run. Might be wrong though. I have the water supply on but my turbo is still glowing red hot after a run to the extent where it had melted the oil return pipe to the sump. Have a leaking turbo to manifold gasket though I'm tinking this could be one of the problems. With the turbo having to spin up more to compensate for the leak.

Cheers
Dave
