Lookin at a 9-5

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).

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
