Overview
A cylinder head stud kit for the Toyota 3S-GTE that replaces the factory head bolts with high-tensile studs, delivering a more consistent, higher clamping load on the head gasket for boosted, high-cylinder-pressure builds.
A budget-priced alternative to ARP for MR2 (SW20), Celica GT-Four / All-Trac and other 3S-GTE turbo builds. Wilson (a Malaysian brand) states the material is equivalent to ARP2000 and SIRIM-tested to 235,000 psi, appealing where ARP pricing or supply is a barrier.
