The Tomei Engine Stroker Kit (part number TA201A-NS05A) is a complete package designed to achieve this displacement increase using an 87 mm bore and a longer-stroke crankshaft, supplied with matching Tomei forged components for Non-NEO engines.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAt the center of the kit is a forged 8-counterweight crankshaft with a 77.70 mm stroke, increasing displacement while maintaining structural integrity under higher loads. Matched to this are Tomei forged H-beam connecting rods in the correct shorter length for the stroker combination, along with a complete set of Tomei forged pistons in 87 mm bore. An oil jet spacer is also included to support proper piston cooling in the higher-displacement configuration. All primary rotating assembly components are engineered to work together, reducing the need to source and match individual pieces from different suppliers.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThis kit is intended for serious RB26 and RB25 builds where greater mid-range torque and higher power capacity are the goals. It is not compatible with NEO engines and requires professional machining, balancing, and assembly for correct installation. Proper supporting modifications, including appropriate engine management, are essential to realize the benefits of the increased displacement safely.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAt Terra Firma Automotive, we supply this genuine Tomei 2.8 L Stroker Kit as a comprehensive foundation for high-output Non-NEO RB builds. Whether the project is focused on stronger street performance or higher-power applications, this kit delivers the matched crankshaft, rods, and pistons associated with Tomei’s stroker program. Choose Terra Firma Automotive for authentic Japanese engine internals that support capable 2.8-liter RB26 and RB25 combinations.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Tomei Engine Stroker Kit\u003c\/li\u003e\n\u003cli\u003ePart Number: TA201A-NS05A\u003c\/li\u003e\n\u003cli\u003eConverts RB26DETT \/ RB25DET to 2.8 liters\u003c\/li\u003e\n\u003cli\u003eIncludes forged 8-counterweight crankshaft (77.7 mm stroke)\u003c\/li\u003e\n\u003cli\u003eIncludes Tomei forged H-beam connecting rods\u003c\/li\u003e\n\u003cli\u003eIncludes Tomei forged 87 mm piston kit\u003c\/li\u003e\n\u003cli\u003eOil jet spacer included\u003c\/li\u003e\n\u003cli\u003eDesigned for Non-NEO engines only\u003c\/li\u003e\n\u003cli\u003eNot compatible with RB25\/RB26 NEO\u003c\/li\u003e\n\u003cli\u003eMatched rotating assembly components\u003c\/li\u003e\n\u003cli\u003eIncreased displacement for greater torque potential\u003c\/li\u003e\n\u003cli\u003eSuitable for high-output and performance builds\u003c\/li\u003e\n\u003cli\u003eRequires professional machining and assembly\u003c\/li\u003e\n\u003cli\u003eTrusted Japanese stroker kit engineering\u003c\/li\u003e\n\u003cli\u003eAvailable from Terra Firma Automotive\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNot For Use With NEO\u003c\/li\u003e\n\u003cli\u003eManual PDF, \u003ca href=\"https:\/\/www.tomeiusa.com\/manuals\/TA201-NS05A.pdf\"\u003eClick Here\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":18356673544254,"sku":"TA201A-NS05A","price":6462.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1992\/7247\/files\/TA201A-NS05A-A3.jpg?v=1727284939","url":"https:\/\/tfaspeed.com\/products\/tomei-engine-stroker-kit-rb28-87mm-without-recessed-pistons-for-nissan-skyline-r32-r33-r34-gtr-ta201a-ns05a","provider":"Terra Firma Automotive","version":"1.0","type":"link"}
