After looking more closely through the compressor maps I have to agree with you. My previous information about which letter denotes what was curtesy of another party and was incorrect.

There's a lot of hard to find information about Saabs. Lots of variants, relatively low production numbers, and few people who tune them. Just look at the data from mellett. Heck even Saab's own electronic parts catalog has one or two mis-prints. That's why I always try to tripple cross reference part numbers with a few other sources (like Nick T's pricing site).

Kudos.

SaabTuner According to what you linked the G denotes "heavier rotor parts" ... but that link is not clear on the matter. If you have another one let me know. The Mellett PDF document has a clear mis-print. The 9-5 Aero uses the same manifolds as the Viggen, and the same turbo. Saab part numbers are identical.

Mellett also lists the G turbo as a 93-98 turbo, when only the 91-93 B234R's have a different part number from later models for the turbo. All of the 9000 Aero turbos are the same from 94-98.

Also the 15 denotes the actual compressor size. Different variant's compressor maps can be seen here: http://www.stealth316.com/2-3s-compflowmaps.htm

The letter at the end appears to denote something about the compressor. However I only have a b versus g comparison to draw that from. None for the t series. Based on the comparison of g versus b it appears to just slightly change the orientation of the efficiency ranges on the map.

mike saunders So, Marko,

Ignore what I said about oval porting the exhaust manifold....

That turbo is the same as mine and should bolt up....

Those are pictures of a TD04H not a TD04HL . The H is a smaller turbine than the HL. I would not expect the exhaust housing from a H to fit an HL. All Saab TD04's are HL.

The G denotes the size of the compressor, 15T is the larger compressor.

SaabTuner Also note that the turbo I posted pictures of has the part number 49189 engraved into the top of it just as you described from mellet, but it is clearly not a turbo which would bolt up to any Saab downpipe I'm aware of.

SaabTuner Yes my car is essentially stock aside from a cooling modification (non-aqueous coolant), different plugs, and no intake snorkel before the filter.

0-100 in 14 seconds is quick enough for now. As I am satisfied with the cold weather performance I'm just looking for the same in warm weather. Warranty is coming up to be over soon though, so might wanna watch out.

Can you get a clearer picture of that label on the turbo? 15g turbos have a different exhaust side to that. In fact ... let me dig up a picture of a bonefied 15g. What you have there looks like a standard 15T.

Here are pictures of a real 15g:

http://www.linuxpupil.com/darthmaula...d04/td04_1.jpg

http://www.linuxpupil.com/darthmaula...04/td04_13.jpg

http://www.linuxpupil.com/darthmaula...d04/td04_8.jpg

You can see that it very clearly resembles the 13g of the WRX. It appears the G denotes the shape of the exhaust side and the orientation of the wastegate.

If your tag genuinely says 15g you probably got one which has been tagged in error. That can happen sometimes in the shop. But your turbo looks exactly like a 15T 06cm.

Happy hunting.

DC_SAAB Adrian.., aka...ahem "SaabTuner"

Just wondering, but isn't your car stock.."in Southern California" with water injection on it?I know your car is a Viggen, but just wondered...

I also wondered what Marko's findings were on his turbo...did you buy it yet?

regards
09-02-2004 02:36 PM
ricot83 the part number on the turbo is....49189-01600 there are new pics up on my website of the 15g i just took them http://www.cardomain.com/memberpage/578615
09-02-2004 02:19 PM
SaabTuner If you have a picture of the 15G I'd like to see it. I know the 1991-1993 B234R has a different part number to the later years. But unclear on what the differences are.

ricot83 i am humbled by u..... o also the 15g turbo off saab 9000s has 6cm housing i have one
09-02-2004 12:52 PM
SaabTuner The 9-5 Aero uses Saab part number 91 72 180 ... Price: $820

The Viggen uses Saab part number 91 72 180 ... Price: $820

The 9000 Aero uses Saab part number 91 49 634 ... Price: $851

Pricing courtsey of Nick Taliafferro http://b235r.hopto.org/Pricing/index.asp

Melet made a number of mistakes in their catalog. These part numbers are from the Saab EPC, which I think we can assume is a tad bit more accurate.

ricot83 actually i do beleive the 9-5 has a 6cm housing i saw that somewhere i will try and find it again but i believe it is right on melett website yep the 9-5 aero has the 6cm housing

Hmmm, sounds like the details aren't something your interested...I'd disagree with you a little on your last... Unless of course you want to mismatch the exhaust manifold outlet with the oval port inlet on the turbo housing.

Courtesy of the information found on Eric's page.. for differences
DC you just totally missed what I said. The 9-5 does NOT have the 9000 Aero's larger turbing housing. It uses an identical turbo to the 9-3 Viggen.

All B235R: TD04HL-15T 05 cm
All B234R: TD04HL-15T 06 cm

(Automatic 9000 Aero's used the T25 IIRC, not the point.)

By " Aero Turbo" Eric meant 9000 Aero turbo.

ricot83 what year is your car and such?
09-01-2004 05:51 PM
mike saunders DEFINITELY Check out Eric's (ERP) site for some of the particulars. You should be able to match up the oil and water lines easily, but you'll need to grind out an oval opening in the exhaust manifold to match up with the oval shape of the Aero's 6cm2 exhaust housing....
