TOMEIUSA/RSE VR41 kit equipped with 274 degree camsTogether with his teammate Kazuya Taguchi, JYR has two cars this year.  Both drivers are competing in an 86/FRS/BRZ chassis, equipped with a VR38-based VR41 stroker kit with 274 duration camshafts, making it an engine with outstanding torque and durability.The exhaust systems on both race cars are beautifully designed JYR’s original, made of full titanium material from TOMEIUSA/RSE, providing not only power but excellent sound.

Round 2 was an impressive Best 32 finishIn the first race, Hiroya finished an amazing 8th place, which gave him the right to advance to the finals in the second race!  Unfortunately, he had a tire bead break in the BEST32 final, and the race ended there, but his performance was so powerful that he surpassed other top drivers in terms of quality, speed, and angle.

The 3
rd race following is in Florida!  The race will be held over two days from May 31st (Friday) to June 1st (Saturday) on banked and angled circuit course at Orlando Speed World in Orlando, Florida, USA.Everyone can watch the race for free via live streaming on Formula-D website, so please grab your pizza and beer and show your support.  This will be Hiroya’s first attempt at a banked course, so we think it will be spectacular.Please look forward to the performance of Hiroya Minowa and his teammate Kazuya Taguchi.

ALL NEW 0.5mm OVERSIZED FORGED PISTONS

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

Saturday final: Achieve the feat of TOP8!

In the TOP32 finals, won against Dylan Hughes and safely advanced to the TOP16.
Then, he competed against Kazuya Taguchi, who is also Japanese, on the same team, with the same RSE/TOMEIUSA VR41!
Hiroya won the close battle by a narrow margin and advanced to the TOP8!

In the final TOP8, he competed against Aurimas Bakchis!
Hiroya placed best 8 as he was eliminated here, but it was a brilliant debut race in the USA, with great expectations for the next race.
