turbo??

[Ford Fester]

So when I grabbed a b8 from the junkyard yesterday I also grabbed a nice turbo. Its a garret from a Volvo 760. Only drawback is it had coolant lines going to it also. I took it apart last night, cleaned it and turned the housings so it will line up nice. Anyone have any experience with water cooled turbos? Can I plug the holes? It has an internal wastegate and I read some on the web and it sounds as if its set at 7 psi.

Yes you can plug the water lines, turbo should work good on a b8

Been pondering turbo'ing mine

B8 AND a turbo!? Nice snag!!

I wouldn't delete the water cooling. You're asking for early bearing failure. Just route one of the heater hoses thru it.

Block might already have fittings for oil/water. The BP does.

This will be on my bp, the b8 is going in a different one

I have used those turbos before without water cooling ( you don't even have to plug the lines if you don't want to as it makes no difference) and beat them like a junkyard turbo should be beat with no problems. Synthetic oil and not shutting the engine off right after running it hard keeps it from grenading. I think that's a 50 trim t3, they match well with1.8 liter engine.

^ x2. Mine has the water holes with nothing hooked to them. 40k and no issues with the turbo

^^^ hmmm... ok then!

I was going off of what a Honeywell rep told me. Talked with those guys alot when I was handling VGT failures on the VT365/Powerstroke 6.0L. She said they have tried both with and without water cooling, and found a significant difference in bearing durability. She said without water cooling, the turbos had a tendency to coke the oil after shutdown. I know this was a major concern on the VGTs, as far back as the Mopar Turbo Is and IIs in the 80's. I guess its not as big a problem on fixed geometry units.

If it's a water cooled turbo, I'd route some water through it. It's really not that difficult, the B8 block should be tapped for it like the BP block is

My 2¢

The vnt units run very hot and are usually undersized for the application, Chrysler had lots of reliability issues back then and they had a poorly designed system. Saab cars have been known to run 300k miles on a single turbo with no water cooling and it was a very similar Garrett unit. I used to work for Honeywell/ allied signal, and have built thousands of their turbochargers through my career. The problem with water cooling the turbo on a festiva is the relatively low cooling system volume. They like to boil out the water after you shut the engine off. normally, water cooling the turbo adds security and safety to the system though and I agree that, given the proper water volume or an after run pump, it is ideal to run the water.

I wasn't saying DON'T do it. If mine were under the hood I would have it hooked up.

My setup does NOT require as much cooling as others.

Rear turbo FTW again....

Oh, I absolutely agree with them being undersized!!!! Lots of issues on the 6.0L and 4.5L (sequential turbos) with excessive exhaust backpressure and compressor cavitation. Glad I'm not the only one who noticed it!!!
