*For competition only. *When installing the Big Bore Kit, it is recommended to install SP Takegawa's Special Clutch Kit to prevent clutch slippage and various exhausts at the same time. *The installation of FI-CON TYPE-X is subject to the user's PC or smartphone environment and internet connection. *There may be changes in product specifications due to the manufacturer's reasons.
*Depending on the lot, the product may be delivered with the old price and label with the old JAN code before the price change.
Based on the "Super Head 4V+R" which realizes the highest class of OHC output characteristics, the "Super Head 4V+R (5-axis port machining) " has high precision machining on the intake port by 5-axis machining center for further improvement of the output performance.) ". The combo kit includes Super Head 4V+R Big Bore Kit 181cc, FI-CON TYPE-X, Big Throttle Body Kit, Large Capacity Injector (G-2) and Spark Plug.
Super Head 4V+R (5 Axis Port Machining) Cylinder Head Details Two intake / exhaust valves are used each to increase the valve curtain area and achieve high intake / exhaust efficiency. The original head shape was designed to balance the center plug, valve pinching angle, combustion chamber shape, and port shape to achieve a higher output than the stock head. The combustion chamber is finished with high accuracy by NC machining.
Intake port machined by 5-axis machining center In order to improve the power output at higher rpm, the optimum intake port shape was designed and the port was machined by 5-axis machining center. The intake ports are precisely machined by 3D programming, and are beautifully smoothed to achieve high intake efficiency.
Valves / valve springs / rocker arms / camshafts ・Unequal pitch valve spring: It prevents surging at high RPM. ・Forged aluminum roller rocker arms are used: The frictional resistance with the camshaft is reduced, and smooth operation is realized. ・Auto decompression camshaft (standard 10 / 10D camshaft): Smooth engine starting is possible without placing a burden on the starter. ・Optional parts (15 / 15D camshaft): It improves the output performance in the mid to high RPM range.See the comparison graph.
Special manifold machined by 5-axis machining center is adopted The manifold has also been 5-axis machined to allow smooth intake to the 5-axis machined intake port. The 3D programmed manifold is beautifully smoothed to enhance the intake effect.
Cylinder, High Comp Piston, FI-CON TYPE-X, Biggs ・Cylinder The cylinder is an all aluminum ceramic cylinder with excellent durability, airtightness and heat dissipation.Black painted surface. An oil outlet is provided so that oil can be taken out to the oil cooler. SP Takegawa Oil Cooler Kit is recommended.Please see our web catalog. An M5 sensor can be mounted on the oil plug bolt. You can measure the cylinder temperature by purchasing SP Takegawa's compact LED thermometer set with M5 temperature sensor.
・High compression piston (compression ratio 12.5: 1 is adopted) Pistons designed for high performance and durability. The piston top is NC machined for high precision.
・FI Controller TYPE-X This is an injection controller that can be installed to the stock ECU with a coupler. Because each MAP is preset according to each engine specification, it is possible to run only by selecting the MAP that suits the engine specification. In addition, ignition timing, acceleration pump, dwell time, reactive injection time, ignition timing temperature compensation, engine temperature compensation, and vaporization time can be set. Advanced players can enjoy the setting based on the existing MAP or create a new MAP. It is possible to monitor tachometer, throttle opening graph and engine temperature by connecting to PC or smart phone even when engine is running. Ignition mode can be selected from EASY and EXPERT. In addition, the rev limit, pit lane limiter and real time MAP change function are equipped.
・Big Throttle Body Kit You can enjoy the characteristic of the engine which turns without stress up to the high RPM range by maximizing the performance of the head. A connecting tube is included to connect to the stock air cleaner box. Air filter kit 03-01-0007 (sold separately) can be installed at the same time to further improve the output performance.
