That's the one that Potterman is getting me.  When I get it all together
I'll see about getting the car dynoed.  Then we can see what kind of
increase it has.  The only problem will be no original baseline. It's a
standard 16V with a 2.0 bottom end so it's probably somewhere between the
123hp and 134 hp of the motronic 16Vs(halfway between the two maybe?).
Anybody know what it costs to get a car dynoed(chassis type).
