The quest for the 1000ps JUN GT-R engine continues with the development of camshaft upgrades for the VR38. To get there JUN have opted for the biggest cam profile so far with 264 degrees of duration on both the intake and exhaust sides. Lift is also the most aggressive yet with 10.5mm on both intake and exhaust.

Pricing is not available yet but perhaps we will be able to probe deeper at Tokyo AutoSalon later this week.
