Exedy Stage 1 clutch kit with Exedy lightweight flywheel.

Honda K-series 5.0 final drive kit – Increase your vehicles acceleration by replacing the final drive unit with this genuine OEM Honda K-series 5.062 final drive kit.

Hasport rear mount – Highly suggested for all K-series with aftermarket header, this will reduce any premature wear/damage to the flex pipe.

As it is, the Honda Civic Si (FG2/FA5) is a great car to drive. And like any great platform there is always room for improvements. The golden rule for all real K-series engines is FLOW! Intake, header and exhaust, get some girth going in these departments. The bolt ons alone will not prove to be anything spectacular at this point, you still have to get your car thinking right. Remember, you car still thinks it is using the factory intake, header and exhaust. It still needs a proper tune. For that we have always looked to HONDATA (K-PRO/FLASHPRO) to get the job done.
