Small Ball Bearing Turbo?
 

Anyone know where to find small ball bearing turbos, or what vehicles they came on? :1

I'm interested in a Ihi rhb31, but it is only a journal turbo, and do to my oiling system I need a ball bearing.....

Any suggestions?

Re: Small Ball Bearing Turbo?
 

No, you do not "need" a ball bearing turbo. ::)

Re: Small Ball Bearing Turbo?
 

Lol.

Re: Small Ball Bearing Turbo?
 

Well I've had a couple turbos freeze up on me by now, I don't think I can get enough oil to them? The only ball ebaring turbo I've used has lived.....

Re: Small Ball Bearing Turbo?
 

that sounds like a user error not a product error. what car is this turbo going to go on

Re: Small Ball Bearing Turbo?
 

They like about the same oil pressures. Starve one, starve them all.

Re: Small Ball Bearing Turbo?
 

whats your oiling systemm, any thing special?

Re: Small Ball Bearing Turbo?
 

hahahhahaahahahahahahaahahahahahahahahahahahaahaha hahahahahahaha
you need a ball bearing turbo like a cock up the ass,

you need to learn what the ---- the differences

Re: Small Ball Bearing Turbo?
 

I'm sorry for the noob questions here fellas, I'm still learning here, that's why I joined this forum to hopefully have some people point me in the right direction :-\

I've "heard" that the ball bearing turbos can live longer with less oil pressure than the journal turbos can.

This turbo is on an Atv, and I extended a banjo fitting to go to the turbo straight off the motor, I think it's only around 8 or 9 psi of oil? It's a dry sump.

With hours of riding, through the Rpm ranges of 2000-10000 do you guys think a journal turbo can live as long as a ball bearing?

Re: Small Ball Bearing Turbo?
 

yes, and you can rebuild it if it fails.

unlike BB which your just fucked with.

Re: Small Ball Bearing Turbo?
 

You can't rebuild a ball bearing turbo?

Re: Small 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

Re: Small Ball Bearing Turbo?
 

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

Re: Small Ball Bearing Turbo?
 

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.

Re: Small Ball Bearing Turbo?
 

OK just makin sure ;D That didn't make sense to me lol

Re: Small Ball Bearing Turbo?
 

Newest pic I got....

The problem is every space under the seat is taken up, I had to trim plastic off just to fit my seat.

And it's not picture here, but infront of the motor inbetween the a-arms is a 5lb nitrous bottle and some brackets with solenoids...... I really have no room left.

So I'm guessing no factory cars came with a small ball bearing turbo?

Nice bike. Yeah the Mazdaspeed Protege came with a ball bearing turbo IIRC, but they were prone to failure. I like JD's idea. Find a way to get some extra oil pressure and then you can run a journal bearing turbo that will allow you a much better variety to choose from and cost you less. Take your Naaawwwzzz off and use it for an oil pump or something. You can make it ------- fit.

Re: Small Ball Bearing Turbo?
 

Or you can just run a Holset! They like low oil pressure (not 8psi though lol). I have a perfect HX-35 I'll sell you. It'll spool at like 30,000 rpm yo!

Re: Small Ball Bearing Turbo?
 

Thanks man, now I just need to find someone that wants to trade a gt2860r for a small turbo :1

Appreciate the advice

Re: Small Ball Bearing Turbo?
 

I have a couple small turbos. IDK if I want a 2860r, but I could probably hook you up cheap. PM me if you want.
