ALL NEW 0.5mm OVERSIZED FORGED PISTONS

All New
0.5mm OVERSIZED PISTONS!

Wide variety of applications
from overhaul to increasing displacement

We have recently added a new bore size to Tomei’s forged piston series, which has received very high praise from engine builders and engineers at tuning shops in Japan by RSE and around the world. The new bore size is oversized by 0.5mm. This is a smaller size compared to our current 1.0mm oversized lineup. For example, RB26’s standard bore size is 86.0mm, and Tomei’s current piston bore is 87.0mm. This time, we have added 86.5mm pistons, which are oversized by 0.5mm from stock. Due to the smaller bore, the displacement is slightly smaller at 2598.6cc for the 86.5mm model than the 87.0mm model’s 2628.7cc. Still, it is very difficult to obtain new cylinder blocks these days, so we have added 0.5mm oversized pistons for those who want to use the precious cylinder block with care and who wish to maintain block strength. Of course, those aiming for the ultimate power can still choose the larger bore of 87.0mmpistons. This time, Tomei would like to increase bore options and help engine builders realize the ultimate engine they are aiming for. At the same time as the piston kit, a new bore size has also been added to Tomei’s stroker kit. We hope that you will complete the ideal engine that suits your purpose and enjoy your car life further. 1

　The VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the ‘lift curve’ (see fig. ①)
which in turn generates more power. (Greater area under the ‘lift curve’ = greater air intake)

　Unlike the valve opening, the VALC profile ensures that the valves close at a slower rate, helping to prevent common valve train related issues.

　With a conventional direct-acting valve train, the maximum lift is usually determined by the size/diameter of the valve lifter. Selecting a high-lift camshaft without taking this into consideration often results in the camshaft lobes travelling beyond the surface of the valve lifter. This causes the lobe to make contact with the edge of the lifter, damaging both components over time. （see fig. ②）
Therefore, the ideal performance orientated high-lift camshaft needs to have a profile that maximizes lobe travel on the lifter without exceeding the outer edge.

VALC profile camshafts have achieved this ideal by deliberately reducing the maximum cam velocity to limit lobe travel on the lifter surface.　（Maximum cam velocity = lobe travel distance on lifter)　

Compared to standard profile camshafts of the same lift, VALC profile camshafts are able to then then off-set the difference for even greater lift/performance gains.
