It's got a swollen body and a fiery temperature ....
Not many people choose to hot up a Saab turbo. They're too expensive and unreliable, plus you can't make them fast, people usually say. Wrong! Unfazed by tuning 'experts' declaring the Saab a performance basket case, Canberra's Mark Kostyrko has built his rare 1980 Enduro 900 into a real surprise packet.
Only twelve examples of the Enduro pack were sold in Australia in 1980. The package - which was fitted by Saab Australia - includes massive boxed guards along with upgraded instruments, improved suspension and big wheels and tyres. Under the bonnet the wastegate was set at a huge 17psi (1.2 Bar), making the standard water injection system an engineering necessity, not just a marketing ploy!
Now don't sit back in your chair thinking it's just a grenade engine; 'cos it ain't. Over 350,000kms have been racked up on the standard engine, which has had its head off only once. While the single cam 8-valve head was detached for a gasket replacement, Mark decided to tackle it with an air-grinder and give it some effective flow gains - but this is the only internal modification.
The standard static compression ratio of 7.2:1 is retained to allow for the big turbo-rush. Incidentally, many of the early Saab turbos were maligned for their 'on/off' power band which was probably caused by this combination of a low CR ratio and high boost - great for max power, but wanting on the road.
Ok? Petter
