Thought this could be helpful to some people and answer some questions that would otherwise mean constant new threads about "What swap do I do?" Yeah some of the answers and info are obvious but hey.

K-Swap info:
The Hasport kits work with either size engine (K20 or K24) and with all the combinations like a K24 from an Accord on the bottom end with a K20A2 head from an RSX Type-S. The K24 motors have EGR built into the head (except the CR-V), and the K24A2 from the TSX has a different ECU and harness. Other than these anomalies, they're all the same electrically and emissions-wise.
*Concerns:
If you've done a Honda hybrid swap, this is no tougher. Three mount points, three new custom mounts. You need a custom exhaust and driveshafts, but Hasport is currently supplying the necessary parts. The wiring is very tricky, however. Plan four to five hours on wires alone if you go it yourself, or just buy the Hasport sub-harnesses.
Emissions may require a lot of work, depending on your state's rules. The 1999-to-2000 cars generally have all the sensors the K ECU is looking for, but other years/models may require parts from newer years/models of Civics to be fully emissions compliant. Though it's unlikely to happen, should you happen to find a TSX, be careful. The TSX has the electronic throttle control which only serves to complicate things.
The K24 from the CRV doesn't have an EGR sensor because the CRV is considered a "Small Truck" and doesn't have to fulfill all the emissions crap that cars do. This could simplify things.

A/C hoses (optional)
Air intake (aftermarket units are easily modified)
Fuel pressure regulator
HONDA PARTS NOT FROM YOUR CAR
