IIRC, the 230hp version had a bit hotter camshaft and the dual cat exhaust system.
The 205hp had a tamer cam and single cat exhaust.

ALL TPI cars from 1990-1992 got the same cam. My auto '91 LB9 put down almost 190whp. So that's almost 230@ the crank. And it doesn't have the N10 dual cat exhaust system.
