ey friend first off thats just broken in for a honda change the timing belt,oil,spark plugs,water pump, and coolant and it will continue for another 250k but to answer ur question common swaps for ur particluar honda would be the honda prelude H22 vtec (4cyl DOHC 185-220hp depending which model you pull from) this motor is extremely powerfull and has many modifications available. this motor ranges anywhere from $500-1700 it just depends on if it comes with the transmission or not. You'll need new axles to handle the power and a wiring harness adapter. good luck and happy tuning
