twin turbo

[ross2313]

im not going to pretend to know much about fabricating turbo set-ups or anything of the sort, but the other day i started thinking, and i was wondering if anyone could shed some light on the subject.
I was wondering if it was possible and if so how hard it would be to do a twin turbo set up on one of the new saab's get it enough power to truly compete with the higher priced bmws and such.

thanks for your opinions

Most Saab engines have four cylinders, using twin turbos on a straight four is quite pointless.

However, Saab is coming with a new twin turbo V6 engine for the 9-3ss. The engine will be based on the same V6 engine as in the 2004 Cadillac CTS. The car will also have a 4WD system from Haldex.

The best thing to do is tune the 4cyl, adding such pieces as a tubular manifold, a larger turbo, and a front mount intercooler. For some strange reason, I have never seen one person out there with a "tuned" Saab.

Saab engines responds very well to tuning (global and Opel engines excluded). Stock exhaust manifolds and heads are good for up to around 400 hp, there aren't actually so many mods needed to reach 400 hp.

There are several Saab that have been tuned up to over 400 as well as 500 hp. There are even one that are "tuned" to run on ethanol, and with a weight of over 1600 kg the FWD car does the quarter mile in 11, seconds, not that bad. But meanest off all Saabs are probably the Saab 9-3 Viggen "Pikes Peak", with 800 hp at 4000 meters altitude (equals 30% powerloss compared to sea level), tubular frame chassi, and a weight of around 1000 kg the car is the current record holder in the class "Pikes Peak Open".

i have a 9-3 aero, what would you recommend to tune to get the most hp for the least amount of money and the most longevity?

Depends on what 9-3 Aero you have. 9-3 (old generation) Aero or 9-3 Sport Sedan Aero. To the 9-3ss we have Hirsch which has a "chip" that increase power to 230 hp, more than that isn't possible without serious modifications.

The engine in the older 9-3 is much better and there are much more choices when it comes to tuning, for example you can look at www.maptun.com

In the older engine no interna parts are needed to be replaced until around 350hp. The pistons can be replaced with aftermarket units or with the older Saab pistons with conrods which are good for +600hp.

Some info about the older engine can be found here:

When you say a twin turbo 9-3ss, you do infact mean a set-up with 2 turbos not the current twin-scroll single turbo set-up?

This thread is quite old, when it was written rumors suggested a twin turbo, but the engine now in production only has a single turbo. A twin turbo version have been tested in for example Aero X though.

i have a few questions my father is passing me his 1999 saab and i wanted to know some tips on tuning this vehicle. has any one raced their saab and if so can you tell about it.
wat is the availability of the viggen (i really didnt feel safe asking that question but i was curious) can some tell me wat a twin scroll turbo is and how is it different than any other turbo?

if you want to tune your 9-3 just go to www.genuinesaab.com they have all the best performance mods and wont damage your engine like some chips. i own a viggen and the car is pretty mean i love it. im getting a stage 3 ecu and full exhaust so the car will be crazzy
