More on History
  • RacingOpen or Close
    The Japanese EF9 had a big name in racing, during the nineties this car was one of the best in it's class and competed in races worldwide.
    Even the Japanese Honda tuner Mugen had and gave it's own view on the EF9 and delivered the Mugen SPL9 to the world. A tuned EF9 that was completly overhauled by Mugen. This racing car had it all, mugen shocks, steering wheel, shift knob, pedals, mugen tuned engine, complete mugen exhaust system, full aero body kit and mugen CF48 rims.
  • OptionsOpen or Close
    The regular EF9 SiRII driver had the choice for some optional extra's like a electric sunroof (but was not an option for the EF9 SiR) a solid-roof, LSD and even with and without electric folding mirrors. Cruise control was never offered; even as an option. Reserved only for the Integra, Accord and Prelude Models. A rather clever option available to the Civic SiR was a map light. It mounted to the driver's A-pillar. The Sunroof on the EF9 was the same used in all other UK, NL, US and Canadian Models. It was your typical Si sunroof, like the EF3 Civic Si, with dash controls and slider cover. The Sunroof came as an option at the time of purchase - as you could opt out just for the standard solid hood.

    The 90-91 model also had fake air ducts, as they are typically termed, but Honda fitted them with Stanley Yellow-Lense Fog Lights as an Option. The EF9 had Variable Power Assisted, pump-driven, Power Steering. This is deemed a necessity in Japan where most times you can not accelerate to help when turning, but rather have to turn the wheels at or near a dead stop to negotiate your way in-and-out of the tightly congested parking lots, roads, and streets. Power Steering was standard on every Civic.

    Another comfort that came on all Civics was Air Conditioning. However the EF9 had automatic Climate Control. You simply dialed in the temperature, marked in Celsius, and the Air Conditioning/Heating System maintained the proper temperature.
    ALB (ABS) was offered on certain models as an option. This was the first Honda system to be used. Used only on 90-91 models it was a very simple design.
  • LSD TrannyOpen or Close
    The EF9 would not be that fast in a sprint if it was not for the incredible Y1 transaxle. This tranny is very smooth and powerful. The engineering that went into the B16A was hand-in-hand engineered with this transaxle type in mind when the Integra XSi premiered it in '89. The Y1 also came optional with an LSD. This factory equipped Y1 LSD Tranny was very strong. The Limited Slip Differential (LSD) is very strong and Quaife [kwaah-f] was contracted by Honda to make this unit. The LSD provided even better corner handling, instant acceleration and traction, and was a streetable unit that was nearly just as comfortable as the non-equiped LSD Differential models.
  • European versionOpen or Close
    The European version of the EF9 SiR was called the EE9 1.6i-VT and was imported into The Netherlands on a limited base between the years 1990 and 1991, only delivered in the Barcelona green pearl G66P, 40 pieces were ordered through the dealers and sold!
    I've started to map all of these 40 EE9's,take a look in the gallery for those cars.
    Other parts of europe ordered more EE9's, till this day i don't know the exact numbers, but only based on speculations and the pictures i have collected.

    The 1.6i-VT is more or less a stripped down version of the Ef9 SiR, it lacks things like power steering, LSD gearbox, ALB, no plastic roof spoiler with long braking led and A/C.
    Things like A/C and power steering were optional on the EE9.
    The EE9, also made in Japan and based on the EF9 weighed 1030kg depending on options fitted like A/C and such.
    The european version shares allot of exterior and interior features as well as engine specs with its Japanese counterpart but there are many small differences.
    Take a look in the model info section for a complete list of differences between these two cars.
