King Motorsports / Mugen EP3 Civic Si

by perry_w 21. January 2014 20:05



For many of us who drive an EP3, we are proud to say that it's the King Motorsports example that inspired us to own and build one up in the first place. Debuted at SEMA 2003, this is the EP3 that more than a decade later still inspires EP3 builds all over the world. This 7th gen Civic was built by King Motorsports for American Honda.





The Nighthawk Black Pearl EP3 was based on the US-spec model and fitted with top shelf performance and body parts that showed what was possible to create from the relatively egg-shaped, minivan outline of the stock 02-05 Civic Si. In order to fit the Mugen front lip, the USDM bumper cover and rebar were replaced with JDM spec versions, which create more of a snub-nose effect in the front. The bumper was finished off with a carbon fiber radiator duct. The stock grille was replaced with a Mugen grille with JDM red badge and driver-side flared opening to allow for additional cooling to reach the Mugen air box. The iconic Mugen hood includes functioning engine bay ventilation.



The rear USDM bumper was also replaced with a shortened JDM version that allowed for the fitment of the Type-R rear lower valence. Type-R side skirts complete the lower body parts. An Mugen adjustable wing was modified for the USDM hatch and pulls out the body line in just the right places.

The changes on the pure performance side were even more significant. A DC5R motor, 6-speed transmission, Mugen ECU, the legendary Mugen twin loop exhaust... the build list goes on and on and is just incredible. It's no wonder the car has appeared in the pages of Car & Driver, Road & Track, Boost and was featured on Speed TV.




Here is the "press release" for the car:

Using Honda performance specialist Mugen's vast array of aftermarket high-performance parts, King Motorsports (the sole authorized North American distributor for Mugen Co., Ltd) has created the ultimate street performance Civic Si that maximizes the potential throughout every corner of the vehicle.

Honda Tuning Quote: Birth of the King

by Administrator 20. December 2013 12:09

We just love the way Brian McGurk described King Motorsports in his Honda Tuning feature on our Prelude Race Car -- we just had to repost it here:

Birth of the King

Body kits, engine swaps, JDM trends, stance, and other assorted fads may come and go, but one company was alive and kicking well before most of it ever entered the picture: King Motorsports. Started in 1981 as the race team of a local Honda dealer, the team piloted their 1200cc '74 Civic to their first victory in 1984. Current CEO Scott Zellner started with the team around that time and recalls, "We ran every race we could with our little Civic, at the same time we started designing parts for them too." Throughout the '80s, the team stacked wins while garnering attention from Honda of Japan. "We got to work hand in hand with Honda Special Projects. They did all the cool stuff; it was a very exciting time." Toward the end of the '80s, King received exclusive rights as the sole Mugen distributor in the U.S., a feat not bestowed on just anyone. After that, gears changed rather quickly. "It was weird; we went from a race team to a parts distributor." Even today King Motorsports is synonymous with Mugen on U.S. shores and Scott, still at the helm, see's no end in sight. "We've been racing and winning for 35 years and we're still here and relevant. I'm very proud of it."

No two ways about it, they're the Kings and that's not changing anytime soon.

Pics from the Shop: 8th Gen Civic Si Kraftwerks Supercharger (Updated)

by Administrator 30. October 2013 17:07


In the shop this week! A fun project: 8th Gen Civic Si Kraftwerks SC installation, then tune on the dyno. All the parts are laid out, inspected and ready for installation.

Engine stripped and freon evacuated from the AC system. Ready to start bolting on the fun stuff......



8th Gen Civic Kraftwerks SC install almost complete. A session on the dyno tuning with a Hondata Flashpro up next. More to come....



8th. Gen Civic Kraftwerks SC kit installation complete! Slide in the new fuel pump and then onto the dyno to make some noise. :)



Let the tuning begin! 2010 Civic Si with Kraftwerks SC kit- stock exhaust manifold and exhaust system. Care to guess what the final numbers will be?


The final results are.......320 whp with stock exhaust manifold, cat and exhaust running 91 octane. Nice stealthy & quiet super sedan! Perhaps our customer Mitch can gives us his driving impressions after a few days!

Update 10/29/2013:

A few months ago we installed and tuned one of the very first production Kraftwerks SC kits for the 06-11 Civic Si. At that time using the stock exhaust manifold and exhaust this car made 327whp and 214ft/lb torque. Now it's back, updated with a Full Race 3" exhaust and Skunk 2 Alpha header -the results 352whp and 225ft/lb torque- nice gain!!!

Watch a video from the dyno tuning sessions:
