Lets hope one of them steps up if Garrett really is losing quality and innovation.

Borg warner is somewhat popular with the Mitsu crowd. My old boss had one on his Evo making about 600hp, the thing was massive, very impressively built as well. I'm not sure about them comapred to Garretts, but it seems like they could be close to on-par already.

^ I have yet to hear of someone who did not like the S256 and S258s for 4G63 apps. Their big feature is a realy 'deep' compressor wheel with the tips extended. It creates some very interesting compressor maps. IDK if they have any ball-bearing CHRAs or not.

borg warner is popular with most people that want the most efficient turbo they can buy.

i guess you guys wouldn't have any interest or friends involved with honda's or drag racing in general to know this, but for the last 2 years, everyone with pro-am or big hp hondas, supras,stangs,monster fd's, pretty much anything, have been switching from gt35,40,42r garrett turbos, to borg warner s352's or something like that. they have been getting better or equal spool, and more hp for less money to boot! personally, when my gt28 dies, i'm going chinacharger without regrets. my galant has had a china charger since 2004, and our shop crx has had one since 2005. and for $175, they can't be beat.

I'm actually on the look out for a Holset HX-27 right now. All my turbo e30 buddy's have been running holset's and love them.

Unfortunately i'm having a very, very hard time trying to find one:crx:

rweatherford 02-25-2010 08:11 AM

I guess the HX-27 comes on some small B-series Cummins?

Where have you looked for one? What is your budget?

Yah all my friends with e30's rave about the holset turbos that they use. Maybe I need to start looking into them.

What holset is about the same size as a gt2860 and do they come with vbands.

Braineack 02-25-2010 08:49 AM

did you ever see the picture of Neo's motor with the Holset attached? IIRC that was a smaller Holset.

Eff.... Looks like I'm going to be searching for a dual ball-bearing GT3582R replacement for my application.

I believe it was used on the 3.3liter cummins motors. The HX-20 & HX-25 are too small for what we need. But the HX-27 is a 28RS equivalent.

No budget. I've just searched the net and sent a few emails to some Florida dealers.

HX-27 is susposed to be close in size to the 28RS but, they have variants of each model and some came with v-bands.

Nope. Got a link? What is a HY?

Braineack 02-25-2010 10:22 AM

it was a he351cw. I'll try to find the pics, I thought i saved them, Neo doesn't have them either.

Precision uses some garrett components. I supposedly have some info coming from them as their website sucks.

BorgWarner to Build Turbochargers and EGR Valves for First Automotive Works (FAW) in China

rbluemx6 02-25-2010 03:40 PM

Most of my turbo experience is with chinachargers, with the exception of one PTE turbo and stock IHI turbos. Chinachargers really are hit or miss and for the price is a gamble I'm willing to take.

cueball1 02-25-2010 06:41 PM

Both have factories in China but maintain facilities around the world. BorgWarner on that page is stated to have 60 locations in 18 countries. Holset has manufacturing in Brazil, China, India, the Netherlands, UK & USA. It isn't where it's built as much as the quality of the design, consistency of production tolerances and failure rates. As much as I'd prefer USA manufacturing but if the best turbo available came from Mars I'd buy it if the price were competetive.

If Garrett is truly having quality and failure issues I hope another company steps up to fill the gap for the aftermarket. Many of the alternative companies don't produce turbo's small enough for our cars. It will then take a change from suppliers like BEGI and FM to make mani's and DP's to fit the alternative turbo units.

Faeflora 02-25-2010 09:01 PM

I say this is all bullshit. There are no garret turbi failures that I've read about here or elsewhere. Fuck the original original poster becaus ehe is yet another big dumb troll plus. As someone else already said up above. China is the big owener of it all so it doesn't mean shit to buy a pt or bw etc. My last final big wondrment on the subject is I wonder what trubies the enduro pro racers use and how well they hold up. It prolly dodnt maayer though becayse they must all get theyrier (got em all!) Turbiyes all custom made with top real merican peruvian hands.

One thing I would think is great to come out of chinih is a real gneuine long style exhaust manifold like the one jayL rocks. That shit is the megabeast.

I am sorry for being reactive, I will not boycott garret becus of that post plus I was bullshintin becus I'm too lazy nyways :/ n so r most of the turboers sof u

I'm just wondering what you run for internals on your motor. The price of a China charger is great, and they are almost completely comparable to the real thing, seen some not flow quite as well, but still damn good, but if the failure of one of the cheap $150 turbos takes out my $1500+ engine, its a big game changer, and it would be a chance I am personally not willing to take. There is a good chance that an intercooler would save the engine from some of the onslaught, but still, if you don't catch it quick or its a slow failure, there's a good chance your engine will be SOLd

rweatherford 02-25-2010 09:53 PM

Might try here for a Holset. I think they carry them. If not I bet they can give you some leads. They do our turbo work on the tractor.

That place is one of the best in the nation for turbo/diesel stuff. We have had them rebuild a bunch of our injectors and bench test injection pumps. If its not top quality, they will let you know.

Stock KIA internals on my FE3 motor. For a complete rebuild from KIA was $600 from the dealer ship in parts. $300 of that were the rods and I got them because I bought my motor with no rods or pistons. More than likely for my BP power goals a stock rebuild should suffice.

I do recall Corky stating over at m.net that even if the wheel were to "explode" it would be mere aluminum confetti going through the motor. But even that maybe wishful thinking. How many of you guys have had throttle plates and screws break and getting sucking through the engine. I know that happened to my friend's 1.6 miata, and the only damage was to the exhaust turbine wheel. It chipped it up pretty good.

As for turbo failures, i have had one where the turbine grinded itself to the back side of the chra, and a friend of mine had his oil seals not seal up properly. That was taken care of via the manufacturer warranty. I have yet to see one fail that catasrophically, and when(not if) it does happen, I'll tear open the engine to see what the damage is. I have my fingers crossed right now.

I agree with you on using quality parts for a built engine, I know I would do the same. But as stated above, stock rebuilds are relatively inexpensive and so are BP's around my area. $150-200 for a junkyard motor in unknown condition. So the odds are even for me at that point.
