I would go B18 with a turbo to best use the engine bay of the del sol for max horsepower while still retaining a normal suspension and weight distribution.

192 from a GSR with bolt ons is possible, isn't it? 170 stock, then I/H/E ... if everything was pefect, in the best of situations, you might get 22 hp? It seems possible, however unlikely. let's say 10 from intake, 7 from exhaust, 5 from headers? Or some combination thereof?
