K Series Engine Parts

Figuring out what you need for fittings and lines can be a pain. This kit makes it easy. Includes all the lines and adapter needed to connect directly to the OEM S2 hardline then back to the OEM S2 return line.

Using Honda's well engineered F Series header, we cut off the F series flange and adapt the header to a K Series flange. This is by far our favorite option when K Swapping your S2000. The OEM Header is built extremely well, double wall for best heat management, never cracks, and just fits like an OEM part. Requires a good Core.

Finally, a complete Plug and Play wiring solution for your 00-05 S2000 Kswap. No jumpers, no adapters, and a base map included! ALL factory gauges work, AC pre-wired and setup in base map. Harness is all Tefzel wire, Raychem DR25, labeled and what most would call "MilSpec."

Brand New OEM Genuine Honda 50° intake cam gear.

This is still to date, our preferred method of doing the Kswap into an S2000. This allows you to keep your factory Fuel system (FPR, rail, Injectors), Throttle Body, TPS, MAP, Idle Valve, IAT, and everything fits like factory. The only downside is you do have to do some trimming to fit your intake manifold. [See pics]. Includes: adapter plate, 6 bolts, and NPT 90* coolant fitting.

Want to use that stock S2000 header? This is our preferred choice when doing a 250hp or less K Swap. Cut off that F series flange, cut the two inner runners, clock them just a touch outwards, and weld that all back together. Do it all correctly and you have perfect OEM fitment.
