Description

GSC Power-Division Toyota 2JZ - Billet R2 Camshafts. The R2 cams are designed for those running large single turbos, larger than 76mm. These cams will not have bottom end losses over our S2 cams; nothing but gains will be seen and will promote great peak power gains. Designed for a rev range of 4500-9000 RPMs. These cams require an upgraded valve spring set such as our Conical Spring kits (GSC5064 or GSC5066) along with shimless buckets/tappets and head clearance for lift. The R2 camshafts are meant for 1500-1800 wheel horsepower. It is necessary to clearance the cylinder head casting to allow for the R2 profile to rotate in the VVTi cylinder head. Please maintain .02" / .5mm min clearance from the cylinder head casting. Intake - Adv Duration: 278?, Duration @ 0.040": 242?, Peak Lift: 11.30mm, Center Line: Variable.
