King Motorsports Unlimited, Inc. - Mugen Performance Products for Honda and Acura

Vintage Catalogs - King Motorsports Unlimited

We recently came across an OG customer who had all three catalogs that King created in the late 80s / early 90s. Each of these hand-assembled catalogs was called a Volume and included a carefully curated collection of Mugen parts, King parts, information about Mugen, and information about King's racecars and services. Each include thoughtful introductory letters written by King's CEO Scott and are a terrific snapshot of Honda/Acura performance culture at the time.

Because we don't spend much time looking in the rear view, we actually didn't have these Volumes anymore in our own library of literature. In fact we only printed about 1000 of each Volume. So Bill Yoon generously loaned the Volumes to us (including the price list inserts) for us to scan and make available to share with our friends!

Mugen's Beginnings


Here is a classic from the archives. These humble and concise paragraphs summarize Mugen's origins (and is even written in first-person). The MF-318 was the first true Mugen engine. Designed in 1973 and based on the Civic 1200 block, this engine was extremely successful in both open and closed wheel catagories.

 

Here is the transcribed text:


MUGEN'S BEGINNINGS


In 1973 Hirotoshi Honda decided to start his own race engine manufacturing company with Masao Kimura. This sparked an interest in racing from a few people in Honda's Research & Development group. Working with Hirotoshi and without pay, we formed Mugen. We all had one thought in mind; to be involved in racing and to manufacture the best race car engines. Our first project was an engine based on a Honda 1200cc Civic engine. We either modified or completely remade everything on the engine, including casting the main bearing caps on the oilpan, in order to add stiffness to the engine, which is required for a Formula race car engine.


The engine was bored out to 1300cc and was entered in the Formula FJ 1300 Racing Series. The engine was very successful, the car won its first race. The success also sparked Honda to return to racing and new Mugen and Honda work side-by-side in many racing projects. Mugen has grown and is involved in manufacturing the highest quality racing and performance parts.
