Nitto I-Beam Connecting Rods - Nissan SR20DET - Silvia / 180SX / 200SX (S13 / S14 / S15)
Nitto's SR20 I-beam rods are for SR20DET builds that go past a mid-level setup, from high-boost street cars to drift and time attack engines. They suit the S13 Silvia and 180SX and the S14 and S15 200SX.
These rods use the wider SR20 GTi-R big-end bearing (ACL Race Series 4B2976H in standard size), not the regular SR20DET bearing.
Nitto I-beams are machined from double-melted 4340 forged billet as a one-piece forging, and have a long record of handling heavy punishment. They use 3/8" ARP 2000 rod bolts and silicon bronze pin bushes.
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
