IMO 200k is a little high to start modding the motor. If I were you and wanted to work with the motor I have I would start by doing a basic rebuild of all basic components with OEM parts. Port the head, upgrade the intake manifold, add a header, some cams an exhaust and call it a day. Since your just looking for some spunk you shouldn't go all out w/a Turbo or try an LS-Vtec conversion on an un-prepped tired motor. Something will be bound to go wrong.
