i was reading wikipedia to get a better compression rate change the current d16 head with a newer model d16 head it being stock should bump up the compression rate. u could place a full exhaust with low restrict cat/extractors/cai/skunk tb/port polish/ecu change or maybe run a apexi safc/change the cams/tune up........but then again all those parts for a d16 engine come from america but u might get the power gains u want doing that $5k is more than enough to mod the engine.
