Eunos Roadster ITBs & HKS High Cam vs Toyota MR-S | Llandow Circuit 2025

Annual trip to Llandow Circuit, one of many battles throughout the day. Changes to the car are new setup, corner weighting, de-powered steering rack and Hankook RS4 tyres for better longevity. Very hot day at 29-30°C so oil temps were peaking and holding at 120° after 3 full hot laps so might have to consider some oil cooling. Everytime I get to this point I consider just buying another car to go full dedicated track car... 👀 0:00 Roadster Intro 0:10 Go 1:42 MR-S Intro 1:47 Touge Battle Start 3:14 MR-S getting sideways 3:50 Overtake 4:50 Cooldown 5:32 MR-S Slide Replay Spec: JDM B6ZE(RS) Toyota 4A-GE 20V "Silvertop" (AE101) ITBs Hummelink Billet ITB adapter manifold with 1/8npt vacuumports Nakayama Racing 70mm Wide bell velocity stacks 0.040″ Head Skim,10.5:1 Compression, ported IN/EX, 3 angle cut valve job HKS High-cams IN/EX 264 duration, 8.7mm lift TODA Free adjusting cam gear (Cam timing IN 108° / EX 105°) Link G4X Plug In ECU Denso EV6 (1.8 VVTi 265cc injectors) NGK BKR6E-11 Spark Plugs NGK RC-ZE21 Silcone Spark Plug Cables Racing Beat 4-1 Manifold & Decat RS-Harada / BRAVE ツナシマオートサプライ 60Φ All Stainless Steel Exhaust (60Φ main pipe and 70Φ Exit) Work Equip 03 15x8.0 & Hankook RS4
