And I replied that this is incorrect. The heads are the same, the block is *effectively* the same. Both are B202 engines as designated by Saab. The ONLY difference between the two engines is the angle where the head meets the block, on a 900 it's 45 degrees, on a 9000 it's something else. Mechanically they are identical. The pistons, valves, cams, whatever all are 100% interchangable. I have the factory service manuals for both 900s and 9000s, and the specs and tolerances sections are the same between the two books. And the plugs are the same too. I swap NGK BCP6EVs between my 9000 and 900s. I buy them in bulk - with four Saabs around I use a lot of plugs. ;) I won't take it personally if you choose not to believe me. All I can say is that with 11 or so Saabs in the past few years I have a fair amount of information at my disposal... -Justin '84 900T (sold 77k) '90 900T (wrecked 134k) '88 SPG (bought wrecked) '90 SPG (54k and going strong) '85 900T (190k and needing a head gasket) '80 900T (the Experiment; 183k) '87 SPG (needs a clutch 125k) '87 9000T (dismantled 190k) '88 9000T (going strong Return to Main Index
