SOME USEFUL INFORMATION ON THE "K" SERIES SWAPS FOR ALL YOU "YOO HOOS" LIKE ME WHO PLAN ON SWITCHING TO THE "SPECIAL K"


K24a1-Honda CRV comes in with 9.6:1 compression and 2.4 liters of displacement. The motor is rated at 160hp at 6000rpm and 162 at 3600 rpm. This motor does not use the conventional VTEC mechanism from the earlier B series motors but does have VTC. Instead it only has 2 cam lobes on the intake side and 1 on the exhaust lob. This motor has no VTEC mechanism on the exhaust cam and runs on 12 valves before 2200rpm. It also has smaller ports than the Type S and Type R. The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.

K24a2- The Acura TSX comes in with 10.5:1 compression and 2.4 liters of displacement. The motor is rated at 200hp at 6800rpm and 166lbs-ft at 4500rpm. This motor uses the conventional VTEC mechanism as the older B series motors but with the addition of VTC. This motor uses a drive by wire throttle and has EGR castings on the manifold. This motor comes with a 6 speed transmission and no LSD.

K24a4- the Honda Element and Accord come in with 9.7:1 compression and 2.4 liters of displacement. The motor is rated at 160hp at 5500rpm and 161lbs-ft at 4500rpm. This motor does not use the conventional VTEC mechanism from the earlier B series motors but does have VTC. Instead it only has 2 cam lobes on the intake side and 1 on the exhaust lob. This motor has no Vtec mechanism on the exhaust cam and runs on 12 valves before 2200rpm. It also has smaller ports than the Type S and Type R. The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.

What K do I want?

K20a-JDM ITR and CTR both come in with 11.5:1 compression and 2 liters of displacement. The Type R motor is rated at 220hp at 8,000rpm and 152lb-ft at 7,000 rpm. The CTR is rated at 200hp and 144lb-ft. Both of these motors have the same VTEC mechanism as the older B series motors but with the addition of VTC. It also has Larger cams, higher compression and larger intake manifold than the Type S motor. This motor comes with a 6 speed transmission and LSD. The 6-speed manual transmission uses multiple synchronizing cones for all gears, including a triple-cone synchronizer in 1st and 2nd gears and a double-cone synchronizer in 3rd through 6th gears.

K20a2-Acura Rsx Type S has 11.0:1 compression and 2 liters of displacement. The Type S is rated at 200hp at 7,400 and 142 lb-ft at 6,000 rpm. This motor also comes with a 6 speed transmission with no LSD. It has the same VTEC mechanism as the older B series motors but with the addition of VTC.

K20a3-Acura Rsx Base and Civic SI models come in with 9.8:1 compression and 2 liters of displacement. The Base motor is rated at 160hp at 6500rpm and 141lb-ft at 4000 rpm. This motor does not use the conventional VTEC mechanism from the earlier B series motors but does have VTC. Instead it only has 2 cam lobes on the intake side and 1 on the exhaust lob. This motor has no VTEC mechanism on the exhaust cam and runs on 12 valves before 2200rpm. It also has smaller ports than the Type S and Type R. The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.

What is I-VTEC? VTC?

The "intelligentî I-VTEC system uses Variable Timing Control (VTC) to adjust "camshaft phasing." By varying oil pressure, VTC can continuously vary intake timing relative to the engine's exhaust timing. The result of I-VTEC is improved response and enhanced performance at low engine speeds and efficiency across a broad power band. This has been coined Hondas gift to tuners. From the factory VTC has not been optimized for pure performance. In the future look for the K series motors with the most power to be optimizing the VTC system.

What is the Immobilizer?

Honda has installed a new immobilizer (type 3) in there 02+ model cars. The immobilizer system has 4 parts: The Key, Immobilizer system indicator, immobilizer control unit, and ECM. All of these must be in place for the car to crank. The key is coded with a transponder id code. The immobilizer control unit is around the ignition switch. It uses an electromagnetic induction to power the transponder in the key. The key then sends its ID code to the control unit. Once received it is matched against the code in the receiversí memory. If the code matches, the immobilizer will send a coded signal to the ECM allowing the car to crank. If it does not match it will not send a code and the car will not crank.
