Do they have different cams over there or is it just the lack > of a cat? I think when we had my gf's '88 900s tested it was 16 PPM or so, I > know the limit to pass for any car less than 25 years old is 220 PPM. Cars upto late 92 didn't need a cat fitted, and could have upto 1200PPM (it was different again for cars pre '74 I think). The cams on the 1985 can be radically different too, the 16v was first built in 1984 and fitted in 1985. And some of the early '85 Model years had a far hairier cam set than the later ones. I've just checked my log book, and it was first registered 9 Nov 1984 (ie a 84/85 crossover, I thought it had actually been regged in 1985) so I might have a set of the early lumpy cams. At 2.5k revs the turbo spools up, and at 3 all hell brakes loose, and I'm shifting at 5k before I know it. It idles nicely if slightly lumpy, and seems not just off boost sluggish, but actually fighting back at low revs, but spin it up, and it really wants to take off. -- Carl Robson (The poster formerly known as Skodapilot) http://www.bouncing-czechs.com
