-Koso 60% stiffer springs
-Drowsports Heavy Duty Billet Clutch Spring Lifter Plate
-Kitaco clutch cover kit
-DROWsports Carbon Fiber Air Intake 34mm

-Aracer AF2 wideband tuner
-Koso 34mm intake manifold
-Koso 34mm throttle body

I remember watching a video from Hard Racing where he mentions the 181 kit is the sweet spot. He mentions reliability and good power. I didn't see an oil cooler. I understand reliability is all about removing heat from the engine.
