Heyi'm goin to look at a 99 9-5 this week n i talked to the guy n he said he think's the turbo's goin out on it(he said there's smoke n lack of power)

I currently have a 96 900SET n i was wondering 1st of all if there's anything specific i should look for to verify i is the turbo?

n 2nd... i've read it's a gt-17 n i could replace it with a td04... does any1 have a link to the info required for this n also what saabs have the td04? (i read the aero has it but idk if any others do n i'm a little out of my knowledge base with the 9-5)

thanx :)

Here is the info you need

Here is what I know
Viggen and Aero both have a TD04 turbo...they are a little different in the manifold and turbo internals, the TD04 from the viggen spools up faster and the Aero has more top end. You can use any year Saab 9-5 turbo...in fact the new ones all come with TD04 turbos...I think starting in 06, use can also use the Viggen turbo, ...the newer 9-3 turbos (which are TD04-14t) will not fit the 9-5. You can also use a TD04 from a Saab 9000 Aero (but why?) most are really shot. I found a TD04-15t from an 06 Saab 9-5 for 175 dollars on Car-parts.com (most have like 30K on the turbos and have been sitting on a shelf for years) just search for 06+ Saab 9-5 turbos...also ask them to give you the turbo intake pipe, it is bigger and better than the older ones...the oil and coolant lines would make life a lot easier as well...you are probably going to want to have software work done on the ECU as well as adding a 3 inch downpipe...In my opinion however, I would take 3-4 hours and inspect the entire car, the suspension, engine, etc and put together a list of things you may need to do and prices, that way you can decide what is most important...for intance if you have 800 dollars worth of work (that is just a number) and that is a lot to you, you may want to rebuild the GT17 for 70 dollars http://compare.ebay.com/like/380246...ff25125&itemid=380246408806&ff4=263602_263632 and not have to spend 200+ on a TD04...I personally see nothing wrong with the GT-17, but people tend to hate them...I pulled mine at 150K and it was still perfect (the wonders of sythetic oils and coolant changes).

You are incorrect on a couple things. The Viggen and Aero turbo are exactly the same. No difference at all. Maybe the tune is slightly different, but not the turbo. Same with the exhaust manifolds, and I believe the intake manifold. A 9000 Aero turbo will not bolt up to the 9-5 cobra pipe (turbo inlet pipe).

thanx for the help, but i went n looked at the car n had advanced auto pull the check engine codes... it brought up

P1230
P1105
P0134
P0133

oxygen n fuel stuff according to them... any1 know anything about these codes???

esp if it sounds like the O2 sensor could that cause the car to idle around 500 rpms n jump/miss in mid throttle (it runs smooth when you 1st push the gas pedal n when its floored)

thanx in advance :)

ok i've been tryin to research these codes n it seems P1230 is a code that has to do with the throttle body n puts the car in limp home mode but idt the car was in limp home mode, it did run on the rought side but i got way over 30 mph n once i got used to the gas pedal issues i could drive around fine ??? any1 got any comments on this?
thanx :)

he's asking $850... n he found out he has a brand new o2 sensor at his house that i'm pretty sure he'd throw in with it. it needs some work but if i could get it running good then all the other little things wouldn't bother me till i got them fixed

Throttle position sensor is in the Throttle body, sounds like the TB ahs failed You can sometimes get them rebuilt for 150 but its a 50/50 thing. BBA reman does a good job and it its toast you will only be out shipping

Otherwise they are 400 IIRC

Oh and some poeple have done Ok with a DIY ( you need to take off the cover and re-insualte all the wires in there somehow ( tape or wire goo) that repair is like 20-30%

Yes sounds right about it being the Throttle Body (which includes the "TCS" Traction control system)...is the traction light on ? I think you mean crank position sensor...most common problem is it wont start with a warm engine and then not start at all. Code 1234 is a bad TCS...your code pattern seems to be pointing to the TB being highly likely bad...
