Up for sale is a good used Saab 2.1 Liter Manifold.  This unit has a flow rate of appropriately 13% greater than the 2.0 intake manifold.  This unit is a direct bolt up to a well ported 2.0 head, or the 2.1 liter cyl heads, as well as the 2.3 cyl heads from the PRE 1993 Saab 900 / 9000 / 9000-turbo.  This intake manifold, combined with a 2.3 / 2.1 head (which also bolts directly to a 2.0 turbo saab engine) will provide a significant amount of increased cylinder head flow, and overall performance.  I have this unit on my my personal car - along with a 2.3 Liter 9000 cylinder head.  It alone makes things flow a lot better, but really shines when you add more than stock boost.  Things really get going around 20 PSI!

These units are common to find on 91 92 & 93 US model Saab 900 / 900-S 2.1 Liter, 140HP non turbo cars.  They are getting to be hard to find here, and non existent in parts of Europe.  I ship internationally!  You probably won't find another one of these...  Please note, this comes with everything you need to make this work!  I always include the fuel rail, 3.0Bar regulator, and fuel pressure regulator + bracket, to make this a direct bolt on for your 2.0 liter engines and cylinder heads!
