I just don't understand how hard it is to make a BB center section when the bearings themselves, are little more than Abec5 rollerblade bearings with different seals. I understand that a completely different center section has to be designed and cast, but should that really net up to an increase of $500+ in the price of the turbo?


...I also don't understand that if the BB technology is the wave of the future, why do we still have sleeve bearing turbo's? I'm sure that if a manufacture produced only BB turbo's they could drastically cut prices to meet up with the demand of the standard sleeve turbos.

Help me shed some light on this ever-elusive "Garrett" centered technology.

Bump for more info...

I'm sure there are others that would like to know...

from what i have gathered, faster spool time and longer life.

DrkGreenAccord

Uncommon? From what I see, most are water and oil cooled. Hooking up extra lines to me is not feasible.... Correct me if I am wrong on that.
Also I hear when the turbo goes bad, it cost a lot more to replace the parts inside.

the way I see it is every body would like to have a bb turbo and if it something that we really wont they make it cost an arm and a lag

yeah the turbonetics bb turbos r alot more, they have there own patented design. i got one off of ebay for around 750shipped brand new. havent ran it yet but i will post my # and spool time and setup when i find out. the specs r t3/t4 stage v .63 exst. and 60-1hifi comp side what type of # should this turbo be able to make?

Mr. Softee

its probably an issue of economics.

I'm sure this is for the most part the main reason...However...

If we're a "Demand Economy"...(and I'm sure any turbo owner would rather have a BB turbo than a sleeve bearing turbo) why doesn't the industry indroduce a low cost BB solution?

I just don't get it.

Suprdave

The low-cost solution is the standard bearing, heh...

Heheh...Exactly. But I just don't understand how the BB section can be so much more to produce than the sleeve type.

Let me ask this...

Why have both bearing types? Clearly both work very well, with the BB being slightly more advantagous...so why keep the old technology around?

do you run your rollerblades at 50k rpm and a thousand degrees fahrenheit? If so, you are a hardcore ****

I dunno, could that maybe have something to do with it?

if he did run his rollerblades at that speed, he'd definatly need an oil tank and have a feed/return setup - that is what oil with turbos do afterall, cool and lube the bearings and allow them to run at 50k rpm... right?

And the reason there are 2 types is because there are less parts in a non bb turbo... non bb = easier to make... also like 94goldjungsr said, its an issue of economics. It also provides a choice for people.

If BBs were so cheap then the regular design would have to become cheaper to sell. Then all of us cheap HT bastards would buy the sc61s for 300 bucks and be just as happy as the guy who bought the garret gt3040r for a discounted price of only 1500 vs the normal 3000.

FORDS- SUCK!!!!

They are much more reliable, I was talking to one of the top tuning companies in my country (New Zealand) and on there race car a porche 911 they were blowing bush bearing turbos frequently they switched to BB and have had no problems, I think its to do with there being much less shaft play(probably wrong). BB turbos are not rebuildable, but unless you don't run a air filter they shouldn't need rebuilding.

Heheheh...I'm sure that does come into account!

Thanks for all the input guys! I'm glad I got this much response.

My freind Seth had this to say...

"people are willing to spend the extra money for the bb.... and they can continue to sell the sleeve for the same price."

I'm sure that it's a combination of manufacturing costs, and economics.

What I really want to see is a company to come out with its own new BB center section turbo that is low cost, and completely own the turbo market...Heheheh

My Garrett GT25R bb spools at 2500, and hits full boost (7.5 psi) at 3500.

HKS/Garrett Japan BB turbos are expensive because they were meant for the Japanese market were people have no qualms about plunking down made cash on the latest trendy item.

That was enough BS! Garrett Japan full BB turbos are so expensive because cartridge type design of the bearing setup. Unlike some turbos that use milled non-bb housings, Garrett Japan uses a high flow cartridge specific housing that required quite a bit of R&D. Eventhough I understand the center housings functionality and proven ability to make more power I can not agree with it's high cost of repair/replacement. A full BB cartridge center housing consumes 60% of the cost of a BB turbo while a standard center housing will normally cost less than 15% of the cost of a standard turbo.

I am pro NON-BB turbo because I can rebuild and make frankenstein turbos with ease.
