I believe the non-turbos run higher compression than the turbos. Usually, Saab runs 9:1 on turbos and 10:1 on non-turbos for the 2.0l; I think the 2.3l runs 9.25:1 and 10.1:1 respectivelty, but I don't know. That is going to be the major difference. The block, heads, and cams are all the same. I don't know about electronics on the newer cars, but on the older Saabs there was definitely a diff between turbos and nons. I've tried... :) Keep in mind, though, that there is more to a turbo than the engine - you also have an oil cooler, an intercooler, a different ECU and a probably a number of check valves and such... These things could be a pain to get in there.... > So my question is did Saab use the same wiring harness (IMHO the > messiest part of the deal) so I could just bolt on the parts I need > from the turbo version, or would it be better to get some other after > market system? Your best bet, IMHO, would be go the LPT route. Get a turbo exhaust manifold and such, and set boost to 5 to 9 psi. At that point, you should be okay and you won't need a new ECU most likely. You'll get a little more off the line punch and probably more passing power without eating into fuel economy too much. I am currently in the process of converting an '86 900S 2-door to a turbo, so I know what this involves. I've no doubt that the conversion on a later car has a ton of little items I don't have to deal with, so I wish you luck. Were I in your shoes, I'd buy a new car. A nice 9-3 coming off lease will be a *much* better car than any NG900, and you'll know it was well-maintained and loved.
