Sadly we don't see too many first gen Integras on the streets these days. Even rarer were the 5-door versions. Here's Mugen's take on that very rare 5-door!

"INTEGRA CURCUIT FORM"

Check out the QUINT GSi sticker as well as the more familiar DOHC SPORTS Mugen sticker.

And here is the version with two less doors, in black! Heavy window and taillight tint really bring out the nose-to-tail graphic stripes!

Check out all our currently available performance parts for the first gen Integra in our online store!

Way back Wednesday- we are going to post the entire Mugen AT Civic Group A parts catalog. We think you'll be amazed at the depth of the parts Mugen made available. You could literally build a turn key competitive Group A Civic from this catalog.

Right-click on an image to see it larger.

The Mugen Group A Civic leads the way. The Group A series was hotly contested by Honda and Toyota with Honda typically having the upper hand...

Mugen Group A Civic engine parts. Forged Mugen pistons with special material connecting rods. There were a few iterations of the connecting rods through the years- some beautifully polished. The Mugen oil pan was a work of art! It strengthened the block and added oil capacity and helped eliminate windage resulting a a 5 hp gain all by itself. The Mugen 30/50 cams were very easy on the valvetrain and had a very sophisticated profile to work with the PGM-FI system.

Part 2 of the Mugen Group A Civic engine parts list- smaller diameter pulleys and the adjustable PGM-Fi ECU and controller. The Mugen hard rubber engine mounts were sold for both race and street cars and made a great improvement! Keeping the engine and engine oil cool was very important- anything over 225 degrees oil temp caused the engine to loose HP.....

Because FIA Group A rules state you must use the factory upper exhaust manifold, considerable time was spent developing the secondary to make the most power. Chromoly lightweight flywheel and AP racing clutch.

One of the big advantages Mugen had over the competition in Group A was a wide range of alternative gear ratios and final drives. With this gearing you could always keep the engine in it's fairly narrow power band. The Mugen Limited slip has been a mainstay of all Honda competition cars all the way back to 1973....

Moving on to the Mugen Group A Civic suspension parts. Here's where things get really interesting. Mugen Showa dampers and upper camber plates, and the really trick front reinforced knuckles designed to be used with an adjustable sleeve that gave even greater camber adjustment. All the different front torsion bar diameters made it easy to dial in the handling to suit the track.

Here we have the quick ratio Mugen steering box (RHD) and 21mm front sway bar. The Mugen rear trailing arms were made specifically to help keep the correct suspension geometry. Mugen made three rear springs rates available, However most opted for an even higher rate linear spring.



The Mugen Group A rear axle with adjustable Panhard rod. The Mugen internal sway bars really worked well and we sold quite a few to street and race enthusiasts. Check out those Mugen 15" wheels......!!!!



We have covered how Mugen made the AT Civic go and handle, so how did they make it stop? 4 piston AP calipers and full floating front brake rotors, single master cylinder and rear disc conversion with all the needed brake lines.



Here's the Mugen brake proportioning assembly and yes- the FIA required a hand brake.....



The Mugen Group A fuel system. A custom ATL 90 liter fuel cell with pump and swirl tank. Don't forget the Mugen gauge cluster with 10K tach. And Mugen SW-36 steering wheel to grab onto!



Lastly the Mugen aluminum FIA roll cage.....



Add up all those Mugen parts with a few hundred hours of labor and this will be you!

Flashback with us to 1984 and the Mugen SW-36 steering wheel. This steering wheel was a popular item back then and is highly coveted by Mugen collectors to this day. When it gets to around -20 degrees F, the leather steering pad could contract and could cause the horn to blow continuosly in the middle of the night-resulting in seriosly cranky neighbors and a visit from the local police. Just sayin.....

We have the latest version of the Mugen steering wheel in stock and on sale!

If you're like us, your passion for Hondas is reflected in the artwork you buy and display. We have a few to share:

Years ago we bought this cloth print at the Honda Collection Hall at Twin Ring Motegi- it hangs proudly in our office.

This mural featuring some of Honda’s most iconic racing machinery hangs inside Honda’s closed-to-the-public R&D facility in Raymond Ohio.

The 100 foot long mural was produced by artist John Frye.

Is it levitation, or is it love?

Mugen and Honda ran a single make racing series using the City Turbos. The cars were based on the production vehicles as were the motors. The motors had larger exhaust, injectors, production type turbo (with 22psi), production type intercooler, and a modified camshaft. These cars did the standing 1/4 mile in 13.5 seconds (which isn’t bad for a frontwheel drive car set up for circuit racing).

They ran very fat tires (9” front and 7” rear). The official Mugen figure for power output is 138+hp @ 5500rpm but the torque is around 22kgm @ 3500rpm (standard twin cam VTEC 1600 has 16kgm, NSX V6 has about 28kgm). It takes little work to produce these power figure in a street motor. The cars from the one make racing series were bought by an Australian entrepreneur with the vision for continuing the series in Australia. Unfortunately all the vehicles were in a warehouse in Osaka waiting to be shipped when an earthquake struck and buried the lot.

Update 2/20/2013:

If you were racing your Mugen City Turbo II in the mid 80's, chances are are you had this Mugen competition oil cooler kit.

Time for an "image tribute" to some classic Mugen wheels over the years. Let's start with the radiating-heat goodness of the CF-48. These are the uber rare black versions with black center caps. The black CRX ain't too bad either!

You have to have the black aero discs (and gold-colored logo / lettering) to go along with them! If you've ever owned CF-48 wheels you know there aren't many aero discs in circulation today...

The MR-5 was easily the most popular wheel of that era. The black-center version with polished lip is hard to beat!

Mugen CR-X Circuit Racer with Mugen MR-5 wheels.....

The M7 wheel is quite rare as very few were sold back in the day. It's all about the SUPER FACTORS!

1. SUPER PRECISION

2. SUPER DYNAMIC-BALANCED

3. SUPER DURABILITY

4. SUPER STRONG

5. SUPER LIGHT

*Update*

Here are a few more additions to our classic Mugen wheel tribute!

Mugen CF-48 wheels with the aero disks. American Honda provided the entire SCCA SSC class field with these wheels at the Runoff in 1985. Quite a sight! This brochure showed them available in GUN METALLIC, CHROME CUT SILVER and CHROME CUT BLACK.

The Honda RA301 was produced by Honda Racing for the 1968 Formula One season. It was introduced during the 1968 Spanish Grand Prix, the second round of the season. Like its predecessor (RA300), the car was co-developed by Lola Cars, and called "Lola T180" by Lola Cars.

The car was an update of the previous season's RA300, using the same RA273E engine. As Honda was also focused on developing the air-cooled RA302, the RA301's development suffered and Surtees only managed a best of second place in the France. Poor reliability saw him managing to finish just two other races.

The car was planned to be replaced by the RA302 at the 1968 French Grand Prix, but Surtees refused to drive the new car because of safety concerns. After the death of Jo Schlesser at that race, Surtees again refused to drive the RA302 at the 1968 Italian Grand Prix, and the RA301 was used until the end of the season.

With Honda's withdrawal from Formula One at the end of the season, the RA301 was the last F1 car raced by Honda until the 2006 Formula One season's Honda RA106.

If wheels were animals, the Mugen wheels would be the ruthless carnivores at the top of the food chain. In that elite pack, the forged MF10 wheels are the dominant males.

Of the MF10 wheels, the best of the pack was the MF10L. The "L" suffix tells the world these are the ultra-lightweight versions of the MF10, specifically made for the race track and only available in white. These are the only version of the MF10 to come in white rather than the standard bronze or silver. Completing the package are unique red and gray graphics sweeping opposing sides of the rim (these graphics are also exclusive to the MF10L).

These wheels are the king of the hill. The MF10L were specifically made for DC2, EK, EG and CRX fitments and were available only in 15" diameter. These are a super light version of the MF10 wheel. Put in perspective, each wheel is only about the weight of 2 of your mom's laptop computers. They are forged wheels so they are super strong and great for racing, which is what they were designed for. Ideal for reducing un-sprung weight -- which translates into faster acceleration and better transient response.

Here are specs for the 2 sizes the MF10L were available in:

Size: 15x6.5

Offset: +45mm 

Bolt pattern: 4x100 

Color: Racing White

Weight: Approx. 10.5 pounds each

Size: 15x7

Offset: +40mm 

Bolt pattern: 4x100 

Color: Racing White

Weight: Approx. 11 pounds each

What if we told you that an extremely limited quantity of the 15x6.5 MF10L wheels were recently found in a dark corner of Mugen's warehouse? And that those sets were on their way to King Motorsports for sale in late January 2013? Follow us on Facebook to be the first to hear the official announcement!

Here's the sticker on the inner barrel of the rim:
