RWD K Series Rear Coolant Housing - K24/20z3 RBB style. Also included is a 1-1/4" to 1-1/4" Inch Hose Barb Splice Coupler to extend your upper radiator hose. [You'll need to source a short hose with a 90* bend.]
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.
Running a K series engine harness but using your stock S2000 (00-05) throttle body? You will need to convert the TPS Connector to the older B series style. Or just use this quick and easy jumper/adapter. plug in and go.
Running the RSX Engine Harness/ECU? This is the chassis adapter to plug it into your S2000. Only works for 2000-2005 year S2000's. IF USING RYWIRE ECU HARNESS- you will use the other Rywire Specific Jumper Harness.
