The LPT is only an option with the 16V models - the full turbo models could be 8V or 16V, usually referred to at the T8 and T16 models around these parts. The "normal" turbo will boost higher (typically 0.6? bar for the T16, 0.75 bar for the T16S/SPG or 0.85 bar for the Carlsson/Ruby models) and has the benefit of the APC system, which can be regarded as an electronic boost controller. The theory is, APC will provide the optimum performance for the car given the vast number of variables - ambient temperature, air pressure, fuel grade, etc. It is an excellent knock protection system. LPT cars do not have this. APC is well worth it, but I've not heard anyone grumble about their LPTs. They're different cars and each have their merits - both are very customisable. Take a look at http://www.nospam/ for wads of information about the APC system ... And tuning it :) Paul 1989 900 Turbo S http://saab.go.dyndns.org/
