This Honda Jazz also known as the Honda Fit in japan is powered by a 1.5L L-15A engine. This car is equipped with full mugen kit all around. In case some of you are wondering, the "R" stands for the owners name.
A 2" 5zigen replica exhaust and custom 1.8" piping from the manifold is installed to increase the exhaust flow and release some power from the engine. To balance the power of the going in and going out of the engine a custom intake is installed to give the car the extra power and good noise. OWS Twin iridium spark plugs are also installed for better combustion. As you can see a functional air funnel directs cold air into the intake.
B+G suspension is used to lower the the car and improve the cars handling in the corners which is the cars strength as the Jazz/Fit chasis turned out to be a good platform which is why J's Racing, Spoon etc chose to build a race car out of the fit and also swapped the engine to K20 and K24 engines which significantly imporver the car's power to weight ratio. The wheels are also upgraded to 17" 205/40/17 wheels.
For entertainment the car maintained its stock head unit but other than that, the speakers are upgraded to Lightning Bolt components which is powered by Lightning Bolt 300.4 amplifiers and 2x 12" Kenwood 12" Sub woofers in ported enclosures are powered by Lightning audio 300.2 amplifiers which equates to good sound quality.
