9-5 GT17 Turbo Replacement

2000 9-5 LPT with 74,000 miles

The GT17 is toast. Its smokes terribly on start-up, everytime and has gotten worse over the last year. The car is noticably slower as well over the same time period. Its gettng dangerous to pull out in traffic. Its also been eating the intake temp sensor every 20k with all the excess oil being dumped into the motor. Why are these Gt17's universally rotten by 100k?

Whats my best option here? Before you say TD04 and software...

This is my mother's DD. I don't think I can sell her on a 850$ T7 tune. I'd rather save her the money and use the t25 off my 96 900SE.

I was thinking I'd rebuild the T25 I have and stick that on there. Would the t25 require new software? I think they are similar size turbos.

Let me sell her on it.

The TD04 is stronger and last longer. Main selling point its a upgrade to a superior turbo.

well the GT17's have the one advantage of being very very cheap as far as turbos go. I have no idea what is required to convert to a T25, but they never came on any 9-5's ever so I would imagine there would be at least some difficulty with either the turbos orientation or the line fitment. You should consider yourself lucky that GT17 turbo lasted 70K, some don’t even last 60K.

FYI, you CAN upgrade to a TD04 and run the stock LPT software. There will be basically no increase in power what so ever from the TD04, but it should not be an issue, you will just have a much longer lived turbo and a hair less spool up. I'd say that's the way to go.

I thought people just like us did this?


The T25 orientation would be correct on the 9-5, as far as inlet and outlet go and rotation.

do a little searching and there is a company in utah that will sell you a rebuild kit, then you can send in your turbo to get balanced. or when disassembling, mark it, both shaft and wheel, and it can be put back together pretty damn close, if your careful

688$ plus shipping is very, very cheap?
The GT17 is more from www.thesaabsite.com than the TD04.

I think I may go with the TD04 so when she gets into her SS convertible in the next few years, I'll just have to run down to Automotion...

well Burnsside was telling me he can get NEW ones from his dealer for $400 some dollars, but if they are selling elsewhere for $700+ than that's probably not right.

The $ 700 is rebuilt and they keep your old one!

Employee pricing ?
Maybe a PM is in order.

If you have a problem with what they do, ask for Nat and he'll make it right.

gt17 to td04 swap is mad easy. just do it and run it on lpt software. it will run fine. t7 will adapt perfectly to it. much, much more reliable turbo too.

As written to the SAAB site,

"I'm interested in replacing the stock GT17 which is nearing its demise with
a TD04 unit from you. Can I send a GT17 core for the TD04?"

Response
"Unfortunately not. Everyone wants the performance Turbo not the standard. We don't have enough cores. TW "

The core fees are identical, he would have had a (significant) sale if he had offered to take the GT17 plus, say 200$. Turning away customers is my biggest pet peeve after work in the customer service biz for a half dozen years, worst thing you can do... I know this should not bother me, but it does

or just find a used one. even with 100k miles, it still has a 100x longer lifespan that a disposable gt17.
