I recently bought a 14b turbo, and soon after my friend whom is ase certified said it wont last over 6 months, because it doesnt use fluid bearings to lubricate it self, i was under the impression that all turbo's used oil that the motor pumps to lubricate there components, which one of us is right?/

I would really appreciate it if someone could give me a quick right up of how turbo lubrication and coolant systems work for the 14b, because i still dont complitley understand.

Thanks.

 

it's an oil/water cooled center section... don't see how your friend thinks it'll only last 6 months... they seemed to last fairly well in the cars DSM put them in...unless he's replying to how the berrings are worn and such.

Ask your friend to explain how 1g (89-94)DSM turbo(14b) cars are still on the road now in 03. The 14b does use oil for lubrication.

 

Alright guys, thanks for the info a lil more in depth explanation on how the oil and cooling systems on a turbo work, i would be very greatfull.

 

Please

 

your friend is an idiot, or you must have misinterpreted him. ya its oil lubricated and water cooled.

Without lubrication it'd last about 10 seconds if your lucky spinning at 60,000+ rpms.

"In order to handle speeds of up to 150,000 rpm, the turbine shaft has to be supported very carefully. Most bearings would explode at speeds like this, so most turbochargers use a fluid bearing. This type of bearing supports the shaft on a thin layer of oil that is constantly pumped around the shaft. This serves two purposes: It cools the shaft and some of the other turbocharger parts, and it allows the shaft to spin without much friction." http://auto.howstuffworks.com/turbo2.htm

 

Thanks guys, i appreciate the info, i believe my friend is mistaken.

 

your friend is a dumbass, an oem would never put a turbo on a car that lasts 6 months.
