900,
The 2.1 liter NA engines are often used on race prepared 900s and the additional horsepower being brought by increased compression ratio, camshafts, header, exhaust system, etc. but these engines need to run 100+ octane.
A simple upgrade would be to employ and exhaust system upgrade which may add 7-9 horsepower. For a more dramatic improvement, converting the 2.1 liter NA to a light pressure turbo could be accomplished by sourcing an exhaust manifold, turbocharger, turbocharger plumbing, etc. from a salvage 900T and install into the 1991 900S. A 5 psi turbocharger pressure could add 25+ engine horsepower without limiting safety.
Search this BB for "LPT" for more info and best regards,
