Hmm, I have not looked into SAAB ignition, Im sure I could graft the R5GTT kit on with minimal fuss.
But as im sure you are aware there is little to gain for power, just a little more drivability and of course economy. All most systems do is retard to 10 degrees as soon as you come on boost anyway, so its only off boost where mine will be effected, mostly on the motorway when you are off boost and you would ideally be running over 25 degrees of advance. But its not like its a daily driver so it will just have to wait till I get around to it.
One thing I would like to get off an early turbo saab is the boost controller they have. It has a knock sensor (a proper one not like you get on most FI cars) and when it detects det it retards boost by 0.1bar, but its a closed loop system so it is constantly trying more boost and feeling for det, You can specify how sensitive you want it to be to det and how much boost you want to run with little potentiometers on the module. And its a stand alone system, not attached to the rest of the loom.
Too much emphasis is placed on the strength of bottom ends, anything less than 30 years old will probably handle more power than anyone dares to boost it to. I used to worry about until I messed a bit with the metro turbo engine. There are people running over 200bhp on the stock crank and rods, which are a 50 year old design, the crank is not counterweighted, and it only has 3 main bearings instead of 5. Sure its probably not going to make it to 15000 miles without a rebuild, but who the hell cares? A rebuild costs little but time.
Its gearboxes that worry me!
