Added the “Green Giant” injectors and the corresponding Nordic Stage? software. The change is not huge. The software is a bit more agressive but there is still the limit of the smallish turbo. The injectors plug right in but since they are a bit longer it requires spacers for the fuel rail mounting. I made some up out of aluminum. The Injectors also require more fuel pressure from a different regulator. These are probably a bit large for this power but 
As always this power thing is addictive and room to grow is nice. I was certainly pushing myluck with stock injectors and fuel press at these power levels.
Bigger Injectors
Been a while..
I have been really busy with the whole GenuineSaab.com business. Not even to mention my New Haas CNC machining center. May new projects are in the works or getting started in production right now. The steering rack braces are a big part I was able to bring in house for manufacturing and both improve the part and lower the sale price! 9-3 and 9-5 stainless downpipes are done.. Now on to Header and big brakes… Oh and to tell about the recent changes to the Viggen. It is stronger than ever and aiming for more. I will get some dyno time in hopefully soon.
Head Clamping
Those of you familiar with the later model 4cyl engines issues with head bolts will understand what a problem they have been. On stock vehicles the head bolts after 50K miles are usually only finger tight! This poor clamping of the head gasket can lead to simple oil seepage cured with re-torque and in worst cases complete failure needing gasket replacement. Most of the problem cars are 1997 through 2001, these had the worst bolt design. For most stock applications one of the latest bolts and a proper re-torque will be fine. However for high output applications where the cylinder pressures are much higher better fasteners are justified. I the pursuit of high output durability on my project Viggen I chose to use ARP studs giving better clamping and long term durability. The studs have a 5 mm hex socket in the top for easy install and are a direct fit. The new fasteners have a finer pitch nut and therefore require less torque to generate the same preload. The materials used are also much stronger (190,000 psi) allowing them to better keep the specified preload. Basically this is not upgrade to add power but will make the power more reliable. This is the most important part of any upgrade plan that is missed completely most of the time. You have to keep it all balanced.
SCCA autocross
I ran the 93 SS in an SCCA autocross this weekend. This particular car started life as a Linear. It now has HR springs, front subframe brace and upgraded rear sway bar. I also ran my 18″ Pirelli Corsa slicks that normally stay on the viggen. This is my first competition in a car with ESP, it is simply amazing. I could not overdrive this car into the corners, didn’t have to throw it at them either. Basically anyone with one of these cars could take it out and have a blast. Just still a little underpowered even though our catback helped a bit.

Site Design
Since I develop and manufacture Saab tuning parts for a living and do this web stuff as a hobby this site is a work in progress and your opinion is important. If you know something that would enhance it please share…
Why no 450hp?
Since this car is no trailer queen and is used for daily commute in the city drivability was my main concern. Rather than go all out with a huge turbo and low compression to allow huge peak power I have chosen to make good usable power.
What is this about the power steering?
Saab never lied about the Torque Steer that the stock viggens have. They put it clearly in the literature under the standard features. Power Steering I will say my viggen has Enhanced power steering.
