{"product_id":"forged-piston-set-86-50mm-bore-for-rb26dett","title":"Forged Piston Set 86.50mm Bore for RB26DETT","description":"The Tomei TA202A-NS05B is a high-performance forged piston specifically engineered for the Nissan RB26DETT engine, with a bore size of 86.50mm (+0.50mm over OEM). This piston is designed to be used with a standard or 2.8L compatible stroke crankshaft.\n\nCrafted from A4032 aluminum alloy, the TA202A-NS05B piston is built to withstand the demands of high-boost and high-RPM engine builds. Key specifications include a 30.00mm compression height (OEM ±0.0mm), a 21.0mm pin diameter, and integrated valve recesses to accommodate valve lift. The piston volume is 10.8cc, contributing to a piston weight of 360.0g and a total kit weight of 466.0g.\n\nThese pistons are part of Tomei's expanded forged piston series, offering a 0.5mm bore increase over stock. This option is ideal for builders who want to carefully utilize a precious cylinder block while maintaining its strength, offering a slightly smaller displacement than 1.0mm oversized options but preserving block integrity. For those seeking maximum power, Tomei also offers 1.0mm oversized pistons.\n\nThe Tomei TA202A-NS05B piston set is compatible with Nissan 32 GT-R, 33 GT-R, and 34 GT-R models equipped with the RB26DETT engine.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873011069240,"sku":"TA202A-NS05B","price":1620.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-piston-set-86-50mm-bore-for-rb26dett","provider":"MOTORMIA","version":"1.0","type":"link"}
