I realize that this forum is primarily for c900's, however, I would like to know if anyone has ever tried adding a NOS system to their saab and how difficult/effective of a solution this would be. I have a 97' 900 SE turbo.

Ask the people at

-they have a nitrous injection kit for Saab, and I bet they have experience on the applications as well.
Basically, all you need is the NOS equipment and some sort of mixture enrichment device to go with the nitrous injected to the cylinders.

Also here...

This company supplied the water injection kit for my 900 T8

I think with Turbos you'll have to use a wet nitrous system.

Wet manifold systems is better in most applications. This is no exception.

Schneid- what other mods have u made??
You might be better off with turbo mods first if you havn't exhausted those avenues....

I haven't had a chance to make any other mods. I am only 16, the car is mine, however, I still need to slowly pull my dad away from it. Thus being the biggest problem I face. The turbo moding was the next question that I was going to have for everyone considering the fact that NOS can be tough on pistons and what not. Does anyone have any ideas for this, or new turbos in general that would be applicable?
Thanks for everything

Why doesn't my dad have a -97 900SE turbo to give me...Not fair. Speedparts Sweden ( a Trionic upgrade for 94-98 900's, they change the whole Trionic and put in free flow air filter. Effect is +42hp and +83Nm in torque. Stick with swedish pages, there's more upgrades including a turbo upgrade (click "Produkter" > "Uppgradering" > "900").

There was an article in last months Car & Car Conversions magazine in which someone had fitted NOS to a Nissan Sunny GTi-R as a means of anti lag. Was able to achieve around 1.3bar boost at 2000rpm!!! Once the turbo spooled up the NOS could be switched off.

I've thought about adding NOS to my 88' SPG. automec1062 said something about a single fogger for turbo applications? I'd like to call NOS and talk to them. Anyone have the number handy? What problems might I run into with adding NOS to my car? I don't plan on putting a huge shot, but something that will put you back into your seat. Any advice?

Kraia- your gearbox.....

Nos is an instant power/torque hit...

you will kill your box no problems unless the utmost care is taken, even still you will be living on knifes edge....

besides, its illegal on the roads in most parts of the world....

You'll need a stronger gearbox soon anyway, if you intend to tune the engine to higher output... The turbo will always give a kick in a Saab, and with increased boost, it's gonna be a bigger kick.

How do I go about getting a better box? I heard that there was a 6-speed that would fit classic 900's. But I'm also looking for maybe a bigger 5th gear. Acceleration is great in SAABs but the top speed isn't the best. What parts need to be upgraded or what kind of upgraded tranny do I need? And where do I get it?

Eriksson Transmission Technik, Jörgen Eriksson. There you can get anything you need. The price will depend on the specification you want, from cheap to not-so-cheap... Jörgen can help you to choose the right combo of parts/strenghtening procedures for your application. You just tell him for what kind of use the car is, and how much power/torque you want to squeeze from the engine - he'll know what kind of transmission you need and will build one for you.

Hmm... shipping a transmission would be quite a lot. How heavy are they?
