Tegiwa<\/a> built this Honda NSX called “Tsuki” for time attack racing. The project began in 2019 when the company found a silver NSX NA1 with a blown motor. Since then Tegiwa upgraded every part of this iconic car which Managing Director and driver Luke Sedzikowski takes full advantage of competing in the Pro 2WD class.<\/p>\n

In the back of the NSX is a turbocharged 2.2 L Honda K-series inline-four built by Bourne HPP<\/a> (BHPP). The motor sits on Innovative K-swap mounts<\/a> and features a Dart steel sleeved block with Arrow Precision crank, Pankl pistons, Arrow pistons, and Race Products dry sump. On top of that is a ported head with BHPP high-lift race billet camshafts, BHPP valves and springs, and Skunk2 Racing Ultra Series intake manifold. <\/p>\n

Tegiwa boosted the K-series output with a Garrett G35-900 turbocharger paired with a Turbosmart Gen 5 blow-off-valve and WG45 external wastegate. A steady supply of E85 race fuel is fed by two Grams Performance 320 lph pumps through Grams Performance 1600 cc injectors. The motor runs on a Life Racing ECU using a BHPP custom wiring harness. Tegiwa maintains intake air temps with an AEM V3 water and methanol injection system. <\/p>\n

The motor produces 750 hp (551 kW) and 500 Nm (368 lb-ft) of torque. The job of getting that power to the rear wheels is handled by a Hollinger MF-2WD six-speed sequential transmission<\/a> with a Exedy Hyper clutch and a pair of Kruger Engineering custom axles. <\/p>\n

Tegiwa upgraded the car’s braking with a Bosch M5 Clubsport ABS system controlling YSR six-piston calipers with 356 mm rotors in front and YSR four-piston calipers with 330 mm rotors in back. The suspension received \u00d6hlins TTX40 Mk2 4-way adjustable shocks, Eibach springs, Hardrace spherical control arms, and ICEFAB custom front roll bar. <\/p>\n

On the outside Tegiwa installed a Route KS widebody to cover the WedsSport TC-105X wheels (18×10 ET35, 18×11 ET15) with Yokohama slick tires. They reduced weight by replacing the factory glass with polycarbonate and carbon fiber rear window insert with a GT500 scoop. Tegiwa dropped more weight with carbon fiber doors and hood. The aero features a carbon fiber front splitter, side skirts, rear diffuser, and DJ Racecars<\/a> custom carbon fiber wing.<\/p>\n

Luke Sedzikowski commands the NSX from a Cobra Ultralite custom carbon seat protected by a Takata six-point harness, MegaLife roll cage, and OMP fire suspension system. Information is diplayed on a AIM MXG 7-inch screen behind the OMP GT3-style carbon fiber steering wheel. There is also a Autotel radio communications system and Garmin Catalyst driving optimizer.
