This is one of the GM engines they used in the 900s re engineered into a SAAB engine called the B204, and this cover is one from one of the engines supplied to Triumph"
Sorry, it isn't! The Redtop is a development by Cosworth of the GM "Family II" 2.0 litre 8v engine, designed entirely in the USA, using (initially) the famous "Coscast" 16v twin cam cylinder head and called the C20XE and later a Vauxhall re-engineered version which became the X20XEV, the notorious Ecotec.
The Saab B204 owes much more of it's ancestry to the slant motor JOINTLY developed by Triumph and Saab in the late 60s. Saab did all the development work that Triumph wouldn't (or couldn't afford to) which resulted in the B204 and it's twin cam siblings. But Saab NEVER supplied any engines or parts BACK to Triumph, the Sprint cam cover is exclusive to the Sprint, as is it's 16v single cam head.
Finally, while it's true that after the GM takeover of Saab, many Saabs became little more than badge engineered Vauxhalls (the 9-3 in particular is on a Cavalier III floorpan and uses the Cav gearbox) the engine was still the Saab developed chain driven twin cam ADAPTED to fit the GM transmission.
It's why I can (and maybe will) put a turbo'd B204 from a 9-3 in front of a Vauxhall Omega RWD 5 speed manual box (which I already have) in the next iteration of the Carledo! It just depends on which motor comes up for the right money first, a B204, or a GM Z20LET! Both will fit with equal ease.
I'll get me anorak and depart now!

EDIT, thinking about it, I think I just fell into Ian's windup! The statement quoted above (which I carefully destroyed) is just the sort of half BS and half myth that a typical rivet counter would come out with!
Well played sir, I walked right into it!
