Show original supplier description
The Tomei TA202A-NS05A is a forged piston kit engineered for enhanced performance and durability in the Nissan RB26DETT engine. This kit includes pistons with an 87.00mm bore, which is a +1.0mm oversize compared to OEM, and a standard 30.00mm compression height. The pistons feature specific ring groove sizes: 1.20mm x 3.05mm for the top ring, 1.20mm x 3.90mm for the second ring, and 2.50mm x 2.95mm for the oil ring. The kit is designed for compatibility with Nissan 32 GT-R, 33 GT-R, and 34 GT-R models. Further specifications include a 21.0mm pin diameter and 60.0mm pin length, with integrated valve recesses to accommodate valve timing. Piston volumes range from 10.8cc to 12.4cc, contributing to different compression ratios. The product manual, available for download, provides detailed installation and usage instructions. Tomei recommends that installation be performed by specially trained mechanics using specialized tools, and advises checking local regulations as these parts may not be street-legal.
