Ti-Al DR-950s

[TurboSinceBirth]

I bought a set of these DR billet titanium aluminide 16Gs aka DR-950s because I wanted a badass setup on a 3.5L. These turbos were purchased off Pensky3Thousand from this thread: 3000GT/Stealth International Message Center (http://www.3si.org/forum/f4/aem-sparcos-td05-ti-al-dr-950s-99-vr4-heads-etc-541653/).

They have 750 miles on them. One turbo had some weld slag from the crappy 3SX TD05 headers come out which bent the shaft. I'm not sure that the Ti-Al turbine shaft/wheel combo will be available anymore. Matt gave me an estimate for a one-off but lets just say that even as a favor you wouldn't want the outrageous price to be upheld. Lol. The rebuild option is a standard TD05H turbine wheel with a new billet compressor wheel, new internals, balance, etc for $895.

Like me you may be disappointed that the cost of the Ti-Al rebuild isn't justifiable and settling on the 12 blade cast TD05H turbine wheel running in any MHI TD05 14b, 16g, E16G, 18G, 20G, etc isn't as nice from a performance standpoint. I took apart the bad turbo and measured the billet compressor wheel. It's an 18G in specs with some extended tips near the exducer which I don't know if 18Gs have. I assume not. You can pick up a balanced ready to go billet 18G CHRA for $470. A machined new compressor housing is another $100. I would also go with a 9 blade turbine wheel for better spool and more importantly a great deal more peak power flow for an extra $160. IMO that would give a badass turbo.

These 950s will give near DR-750 spool but can supply 150+AWHP more power which would be sweet on any 3.0L or 3.5L. It's perfect for someone that already has 16Gs. I will let them go for what I paid $1375 plus shipping.

Here's pics of the damaged turbo:

You can see it needs a complete rebuild because of the damage. The shaft is bent along with the wheels being damaged so it needs new bearings, maybe a bearing housing, and a full rebuild obviously which is why I recommend a new CHRA.

That comp wheel looks huge. Know the sizing on comp and turbine wheels?

The turbine wheel is the exact same size of a TD05H turbine, 56mm inducer and 49.2mm exducer. It's a much lighter wheel and shaft though which is where the spool/power advantage will come from. I suspect that the wheel and shaft are one piece which is why they both have to be replaced on the other bad turbo sitting currently at Matt's turbo shop. I took apart the compressor side and found out the compressor wheel is a billet 18G wheel in inducer/exducer specs. I'm not sure if a billet 18G has extended tips in the design. You can get a billet 18G CHRA with a 9 blade turbine for about $730. Ideally, that's probably what I would do.

It's $895 to rebuild the bad turbo with a new billet compressor wheel, stock TD05H wheel/turbine, new seals, rebalance, bearings, etc. I've seen cheap 16G external kits under $1k you could couple with these turbos.

Anyone want some badass turbos? If you know a DSM friend that would be interested in the good turbo let me know also. I need to get these sold.

Just the shaft is bent? Not any of the turbine blades?

Just the shaft was bent. Unfortunately the turbine wheel and shaft are one unit. Neither the compressor wheel or the turbine wheel would touch/rub when you spinned it by hand.

Edit: Upon closer inspection the wheels did rub as can be seen in the pics.


If it doesn't sell eventually I will rebuild it but not for another few years until I have all the rest of the mods ready. Ray made over 760AWHP on E85 with a regular E16G set on a 3.5L. These will flow even more and will spool much quicker. I had planned on using them with a 3.5L.

I must have missed that one. Can you point me to thread? Most I know is Chris at 715awhp.

My bad. It was 748AWTQ not HP. I have a hard time keeping everything straight going off memory sometimes. Lol. Still very respectable numbers on stock heads and cams too. big engine little turbo dyno test - 3000GT/Stealth International Message Center (http://www.3si.org/forum/f1/big-engine-little-turbo-dyno-test-546885/)

Dyno numbers imprint in my brain:). It's like baseball stats when I was kid.

Free bump. These would be RIDICULOUS turbos in a 3.0 or 3.5!

Damn would be nice if these could be flanged for TD04... :bigthumb:

You could always run some adapter plates. ;) Lol. Given enough time I'll figure out what to do with them. I wanted to see if anyone else would like a chance to own a set since they'll be sitting on the shelf for awhile. By that time I'm not sure Matt will offer a Ti-Al replacement for a one-off run. It's just a stock wheel/shaft in a lighter material so I'm sure another company could make it although it would still be costly.

I've got some current interest in the good turbo itself probably for a DSMer.

This is just the turbos?

Yes just the two turbos. I don't have anything else to make a complete kit unless a buyer wants some Tial 38mm wastegates for extra. I gave Matt the ok to put the bad turbo back together and send it back to me as is.

I got the turbo back from Matt finally. I'm selling it as is and put up some pictures of the turbo. A rebuild is $895. After checking into the Ti-Al rebuild, Matt begging to get a one-off made, and me not going through with the expensive rebuild I'm going to guess that the Ti-Al wheel/shaft will never again be available so the standard TD05H wheel is the available option.

I updated the first post with some pics of the wheel damage. It's more extensive than I thought just looking at the turbo assembled so I now understand why a complete rebuild is necessary. I listed some options but I'm very close to keeping these and going with a billet 18G or 20G on the bad turbo with a 9 blade TD05H turbine wheel.
