Saab 9000 Turbo? What is it?

himilefrontier · Sep 29th, 2005, 01:53 AM

I found a few complete Saab 9000's at the local U pul It yard with turbocharged 2.3 liter engines ( one was a 9-3). The yard asks a super-cheap $95 for a turbo and $45 for an intercooler ( including core), so I was wondering if anyone knows what turbo these cars use? The newer one said it was a Garret and the older ones said "Air Research" on them ( which makes sense to me as Garret Air Reseearch is the whole name of the co.). I figure they are probably T-25's, but how can I know for sure? Also, has anyone used one of the giant intercoolers off these things on a Sentra ( It's like 15x20!!)? The piping looks like it would be easy enough to adapt to my B14 and I would like to use the whole setup as much as possible ( but substitute a 1G DSM BOV instead of the plastic one it comes with). As a final note, does the Q 45 have the 370CC injectors on it, or are they just used in the Z32 300zx Twin turbo?

im almost positive that they are t3's
and airesearch is garrett.

ive been lookin for a t3 so if you can find another and wouldnt mind sending. ill give you some cash pm me

im pretty sure saab runs a T3 which would be slightly big for your car.

Not necessarily... Depends on the exhaust housing. If it is a T3 it is more than likely a .63ish exhaust housing which may not be too bad... Granted I firmly believe T25/28 is a better match.

Just be careful that they do not use proprietary flanges, or you will have to engineer/fabricate around that. Just another reason why I advocate the use of SR20DE-T T25's/28's as they use common Garrett flanges.

I do agree that a T25/28 is a much better turbo for a GA16DE than a T3 would be, and my other option is a 2G DSM turbo or maybe even a 13G off a 1G DSM, both of which would probably be better matched.( But I'll keep the Saab in mind then for a planned twin turbo 6 liter AMC V8 I want to build when I get an easier project under my belt....Muhahahaha!)I drove a Saab 9000 turbo about 10 years ago and remember it being a little laggy. What would tell me what kind of turbo I am looking at? Is there somewhere to look on the housing to see if it will be what I am looking for? I liked the Saab piece better than the DSM piece because it would be easier to package the piping with a intercooler with opposing end tanks rather than having them on one side. The DSM would require me to use a J pipe and I want to avoid any restrictive 180 degree bends if at all possible. Where would be a good place to find a SR20DET T25/28 from-cheaply?

Cheaply is a relative term. You can get them for less than $200 on SR20 forums sometimes. Otherwise you just need to look around. You are going to wind up with things that are less than ideal when using a turbo not suited for the car such as different flanges and things of that nature. Even the DSM turbo's use specific flanges....

Have you ever worked with a turbocharged car? You will find things different when you actually get in there and start building it...

The only turbo car I have ever messed with is a friend's 1993 Eclipse GSX. We did some basic stuff-bleed valve boost controller, new stock BOV, timing belt,UR pulley, fuel rail,transfer case, etc- but nothing extremely complicated. One of the main purposes for me to do this project is to learn about several technologies which I have no major experience with on a car that will shortly loose it's usefulness, has no real value because it is so cosmetically trashed-yet is mechanically perfect.I am using it as a guinea pig for the turbo, ECU, quarter panel replacement, learning how to upholster seats, and front drive chassis setup. I also learned how to fix A/C, hub bearings, half shafts, rack and pinion steering, tint windows and section the front end of a wrecked unibody car with it. Should I kill the GA it will suck, but replacements are readily available at my choice of U pull it junkyards if need be. My next step will be getting a set of wheels I located while delivering pizza tonight that are perfect for what I want. (15x7 Rotas with Falken Aziens tires in 205 50-15) Then , I'll put my AD22VF's on, and rebuild a set of lower control arms with new balljoints and poly bushings. Next, is a set of home made strut tower braces that a friend and I want to try building, and possibly a under car chassis brace too. Following that is a 5 speed swap with a Phantom Grip LSD and then the turbo setup.I plan to research every possible angle and learn all the theory I can while gathering parts over the next 4 mos. I hope I will find someone doing a turbo project that I can help out and learn from too, but am willing to fail in order to some day succeed.

OK, my research found a number of refrences to the turbo used on the Saab 9000, and the early ones were all T-3's. However, some of the later ones used a "low boost' setup with a T25 or a small Mistu turbo......TD04 IIRC.

Oh, and one more thing about my plans is that I want to use a Megasquirt ECU which is speed density, eliminating the MAF sensor. I also plan on doing the engine management in stages. First, I plan on pulling another B14 ECU harness at the local u pull it and stripping it of everything not necessary for the Megasquirt to work with. Then, I will connect the Megasquirt to the engine and get it to run right on the stock engine. Once I learn how to tune it properly to make it run well stock, I will move on up to the turbo.This way, if it won't run on the Megasquirt, I can always plug the ECU and harness back in and have it going in the stock configuration. I also have a 4-6 month time frame to find everything I need at prices I can afford, giving me plenty of time to do research and examine other people's good and bad turbo setups. I would also appreciate any intelligent input on my plans/ideas as well as suggestions on books/magazines/websites to read ( I read SCC, Hot Rod and Car Craft right now-I also have 2 V8 cars I built from scratch). I am here to learn from those who know more than me.

You want to find a T3 from a saab 900, .42/.48 either garret or air(same co)

The 9000 used a bunch of different ones but none of the turbines are really suited for under 2L's...

Zen31ZR · Oct 16th, 2005, 10:39 AM

Seems to me SAAB used to run T3s, but that was a long time ago. Now they use T25s/28s for more low end and faster spool up. SAABs used to be the laggiest of all turbo cars, but what a rush when the turbo kicked in.......

nissan300zxmike · Nov 1st, 2005, 08:22 AM

i have a garrett t03 turbocharger .42 compressor trim/.48 turbine trim on my 68 vw fastback...engine is fully built, 1.6 litre displacement and with that turbo i get 72% efficiency (the middle island)
