I like the history of Honda Performance and Racing. Undoubtedly Mugen is one of the premiere Honda Tuning agencies and with their long standing ties they have built up quite a bit of history. The Mugen MF204 F3 Racing Engine was developed some time around 1988 and ran in the F3 Racing Cars. (Information Courtesy of www.Mugen-Power.com) "Following F3 regulation requiring use of commercially available engine blocks and heads, B20a mounted on Prelude was modified into it. (Mugen MF204 Engine) Due to regulated exhaust limit, development was extremely difficult, however, MUGEN won the Japanese F3 constructor's Championship for 3 consecutive years, and the engine was used in European F3 and won many times."
