OK Here we GO !
Its about time I have a go at doing my own very first turbo conversion. The turbo that I have is off a late 90's Holden rodeo diesel, However its is WATER cooled and OIL cooled from what I can see. What I was asking is...

*Is it possible...
*Can I just block the water channels and only cool it on oil...
*Do I need to fit a after market oil cooler...
*Do I need a bigger oil pump...

I really only want to run it on low boost nothing crazy just a little fun and sneezing... The engine that its going on is a 1600 dual solex which I need to do carby kits on... and bolted up to a 1300 or 1200 gearbox not to sure...

kind regards
Mick

thats a 23 year old turbo, did you get it for free??
maybe find one with out water pipes.???
this complete turbo including the exhaust cost about $2000. just bolt it on and turn the key.

You can run happily without water, no need to block them off etc. Just dont switch it straight off without letting it idle for a couple of minutes when it's hot. I doubt you'll need additional coolers etc but install a temp gauge so you can keep an eye on things. Sounds like cheap fun, keep us updated.

Stock oil pump will be fine but you will have to suck it and see as to the oil cooler.

I had dramas with mine, the hot oil return from the turbo was just too much for the stock oil cooler to cope with, was fine before and after I removed the turbo setup but the turbo itself had rooted bearings which probably wasn;t helping.

thanks for the replys and yes I will keep you posted...

Ideally a turbocharger with a water cooled core should be water cooled through a coolant pump and heat exchanger.Early nissan exas and Pulsar ET Turbos were all running oil cooled only turbos from the factory..and many suffered turbo failures to the point where nissan recalled them and fitted them with oil and water cooled Garrett units.

The reason manufacturers went with water cooled housings was due to the problems with the lines, housings etc coking up after abruptly shutting the engine down (and stopping supply of cooling/lubricating oil). Manufacturers have to account for owner stupidity. You Don't.
This is why turbo timers were invented, something you don't see so often these days.From memory the factory VW turbos I used to work on over 6 years ago would continue to pump coolant after shutoff from a little electric pump. If it really concerns you set up something but it's overkill.

You don't see turbo timers much now as they are illegal in most states.

Plenty of modern cars are still around without water cooled turbos, my 2003 Navara for example didn't have a water cooled turbo.

THey are perfectly fine as long as you let the engine idle down so the bearings cool off for a minute or 2 before shutting down.
watercooled are just to cope with todays oblivious drivers.
