Stud Kit for Nissan SR20DE/SR20DET Engines

The ARP Head Stud Kit 102-4701 is engineered for Nissan SR20DE and SR20DET RWD engines, offering a significant upgrade over stock head bolts for high-performance builds. These studs are crafted from premium-grade 8740 chromoly alloy steel and heat-treated to 200,000 PSI, providing superior clamping force. This enhanced clamping power is crucial for maintaining a perfect seal between the cylinder block, head gasket, and cylinder head, especially under extreme high boost and high compression conditions. Proper engine sealing is paramount for preventing common issues like power loss, overheating, and oil contamination, which can lead to catastrophic engine failure. ARP head studs, particularly when paired with a metal head gasket, are a critical element in achieving this reliability. The kit includes assembly lube, studs, washers, and bolts, along with detailed installation instructions. The use of 12-point nuts and M11 x 1.5 thread size ensures a secure and precise fit. This head stud kit is specifically designed for various Nissan Silvia and 180sx models equipped with the 2.0L SR20DE and SR20DET engines from 1991 through 2002. Applications include the S13, S14, and S15 chassis, covering both naturally aspirated and turbocharged variants. The product is constructed from 8740 chromoly, is heat-treated to 200,000 PSI, and features 12-point fasteners, with no undercut studs.
