You can't rebuild a ball bearing turbo?

you can try but fail

Re: Small Ball Bearing Turbo?
 

Those conditions you described are about as worse as any I've heard a turbocharger have to perform in. It's no coincidence you've been going through turbos and the one that survived is ball bearing. These guys all hate on ball bearing turbos, but they do indeed require less oil pressure to maintain lubrication. It is an advance in technology no doubt, but as with anything, the more complex it is; the better the chance of failure.

Journal bearing turbochargers are relatively simple and can be re-manufactured with a somewhat decent rate of success. If it's a complete failure though; even the journal bearing turbos are so expensive to repair it's not worth it. If you have the money to be buying $1000 turbos that may still fail, then by all means go with a ball bearing cartridge. Just my $0.02

dood you dont even NEED the ball bearings. 9 out of 10 dentits recommend you hookup your coolant lines to the oil lines, itll run hella cooler and the turbo will spin faster because of the water wheel effect!

Re: Small Ball Bearing Turbo?
 

Most modern journal bearing units need 15 psi, same as the baller bearing ones.

An oil pump that would raise oil pressure 8 psi is cheaper than a singl turbo. Do the math.

Re: Small Ball Bearing Turbo?
 

I wanted to do an oil pump.... but I just don't have the room on here. With my turbo setup taking most of the room, and my nitrous bottle and solenoids I just don't have anywhere left to bolt anything or make brackets >:(

So I should try routing my coolant lines to my turbo instead of oil????? I'm running a non-intercooled set up right now, would that make my coolant hot as sin?

I like the turbo on here, it's lasted me quite a while, it just doesn't start making boost until 6500rpm..... and going up and down hills with large amounts of load on the motor.... for hour on ends, I just want something to last a little while.

But if you guys think a journal turbo will last as long as a bearing turbo and I'm more than up to try for it.

Like I said I'm learning as I go along.... any advice is appreciated

Re: Small Ball Bearing Turbo?
 

if you got money to throw away on turbos over and over get a aero charger turbo. it has oil in it like a car engine and you just have to change the oil every once and a while

Re: Small Ball Bearing Turbo?
 

Just run a leafblower. No oil needed. Just attach the throttle cable from the blower to your atv's throttle cable. End of discussion

Pics of this FO wheeler please sir.

Re: Small Ball Bearing Turbo?
 

lmao no dont run coolant instead of oil....that will equal epic fail..

sounds like you need more oil pressure, so im thinking your best bet will be to buy a new oil pump that can get the pressure you need.
