The Honda NSX has been an iconic car for a long time. Nowadays we are expecting orders for the new generation to start, but I still feel that the old car is much more fun to drive. So how do you improve on such a legend?
Jun-san had his idea on how to get the perfect NSX. It would not only have to be a sportscar but also to be delivering good performances on tracks like Tsukuba and Fuji. He has had this NSX in its OEM form until he finally started to modify it. First of all, the Marga Hills front bumper received a pair of carbon fiber canards, a carbon splitter and an undertray. This goes all the way back and seals the underneath of the car for perfect air cutting. The vented bonnet has been provided by Advance and it helps radiator and oil cooler temperatures stay in control. Next came a set of Marga Hills wider front fenders and carbon fiber sideskirts, Marga Hills rear fenders and a set of Magical Ride side mirrors. The GT wing is made out of a Garage BB main wing and a set of carbon fiber Matrix stays onto the factory wing mounts.
The car sits on set of RAYS Gram Lights 57 Extreme wheels that measure 9×17’ upfront and 10.5×18’ in the rear. They are wrapped in 235/40ZR17 and 265/35ZR18 Dunlop Direzza Z2 tires, front and rear respectively. This is the street setup, for the circuit the wheels are replaced with a set of RAYS Volk Racing TE37SLs, measuring 9.5×17’ upfront and 10×18’ in the back. In this case the tires of choice are Yokohama Advan A050 M, measuring 345/40/R17 and 265/30R18. The front and rear brakes are two sets of 4-pot Brembo calipers with two piece slotted floating discs. Jun swapped the suspension with a set of Advance Bilstein E12 adjustable dampers with Eibach springs and Advance pillow-ball bushings.
All these mods were necessary to cope with the Toda 3.1L stroker kit including a set of Toda high compression pistons and Toda Type-A billet camshafts. This setup is good for 350 hp in a car weighing 1,200 kg. The engine is managed by a custom mapped HKS F-CON V Pro piggyback ECU. Other modifications include high-flow Fujistubo exhaust manifolds and an Advance titanium exhaust system.
The driveline has also been upgraded with an Exedy twin-plate Carbon-R clutch and a light flywheel, an OS Giken 1.5 way diff with a 4.4 final gear.
Interior modifications are scarce but track oriented: a Momo steering wheel with a quick-release hub, a pair of Sparco REV2 seats and Sabelt harness belts. And then there’s the dashboard…Jun kept the NSX’s fuel, water temperature and volt gauges, created a carbon fiber dash and installed a Defi Smart Meter unit.
