By using SP Takegawa's compact LED thermometer set with M5 temperature sensor, the cylinder temperature can be measured.\n\u003cbr\u003eBore diameter 63mm. Stroke 57.9mm (stock).\n\u003cbr\u003eThe piston is standard specification for high-octane gasoline.\n\u003cbr\u003eCompression ratio standard piston 11.0:1.\n\u003cbr\u003e●Sports Camshaft (N-20)\n\u003cbr\u003eThe optimal profile maximizes the performance of the stock cylinder head, improving output performance.\n\u003cbr\u003eWhen installed on a stock engine, the output in the high rpm range is improved.\n\u003cbr\u003eRegarding the Sports Camshaft (N-20), by removing the decompression parts from the stock camshaft and installing them on the Sports Camshaft, it becomes an auto-decompression specification.\n\u003cbr\u003e●FI-Con TYPE-e (Injection Controller)\n\u003cbr\u003eWhen installing a sports camshaft or muffler parts, the air-fuel ratio will deviate significantly from the ideal, so it is necessary to correct the fuel injection time with the FI-Con.\n\u003cbr\u003eInstallation is possible by simply unplugging and connecting to the genuine ECU coupler.\n\u003cbr\u003eThe FI-Con TYPE-e has multiple data sets internally configured by SP Takegawa to match SP Takegawa engine parts, so you can easily select, change, and modify settings data using a computer or smartphone according to your engine specifications.\n\u003cbr\u003eThe injection time can be adjusted with a maximum increase of 5000μs and a maximum decrease of 7500μs, making it widely applicable from stock displacement to bore-up vehicles.\n\u003cbr\u003eIt is equipped with monitoring functions for engine speed, engine temperature, throttle opening, and injector opening\/closing rate using a computer or smartphone, making it very convenient for setting.\n\u003cbr\u003e●Big Throttle Body Kit (with connecting tube)\n\u003cbr\u003eKit composition: The big throttle body kit for stock cylinder head comes with a connecting tube for big throttle body (connects to stock air cleaner box).\n\u003cbr\u003eIt maximizes the performance of the stock cylinder head and achieves high output.\n\u003cbr\u003eYou can enjoy engine characteristics that rev smoothly up to high rpm.\n\u003cbr\u003eBig throttle body bore diameter: φ34\n\u003cbr\u003eThe big throttle body kit includes a fuel injector ASSY.

It includes products with different sizes and colors.\n\u003cbr\u003e※Product design and specifications are subject to change without notice. Please be aware.\n\u003cbr\u003e※Due to the significant increase in engine output and torque with the installation of SP Takegawa S-Stage bore up kits, the crankshaft will experience increased stress such as twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the load on the crankshaft. The crankshaft support adapter enhances crankshaft durability by adding ball bearing support to the end of the crankshaft flywheel side, suppressing twisting and deflection.\n\u003cbr\u003e※Since this product is made to order, cancellations after ordering are not possible.\n\u003cbr\u003e※This product is made to order and takes time for delivery.
