The Enmo Racing Twincharged Civic was built specifically for Street Class – Time Attack racing. Built to the full extent of the rules, the car has proven itself as a daily driven track car. This car holds numerous track records in both Redline Time Attack and the Ontario Solosprint Championships. Also, it recently finished in the top 10 during it’s first year of competing in the 2010 One Lap of America.

The car and it’s modifications have been designed and built by the car’s owner, William Chan. Since 2005, the car began it’s competition life primarily in autocross events. William’s work opportunities saw the car driven across the United States twice. While on the west coast, the car competed in numerous SCCA San Diego Region autocrosses as well as the SCCA National Tour. Currently the car is in Ontario, Canada where it competes exclusively in Time Attack and Time Trial Competition across the eastern United States and Canada.

The SOHC D16 engine was retained to provide a more optimal weight distribution than the heavier B and K- swap motors. This results in measureable handling gains, especially for a FWD car which starts with far-from-ideal front weight bias. Power increases are provided by a unique turbo and super charger setup. The combination of both compressors provides a wider and more efficient powerband over the usable RPM range while also meeting peak power goals. In it’s current form, the 1.6L engine produces over 300hp and 250lb-ft of torque. That’s more HP/Litre than a twin turbo Porsche GT2!

    I am wondering how is that rear wing mounted on the car? Do you selling the mounting kit for it? Also do you have any pictures of the rear of the car with the mounted.

    It is a custom design and fabrication. There are two versions that you may have seen. The earlier one is for a GTC-200 wing. The mounts are centrally located. I no longer have use for these mounts and would be willing to sell them. A new GTC-200 wing can be easily modified to fit. A crash at a Redline Time Attack event resulted in irreparable damage to the wing but the mounts are still in great condition.

    The GTC-300 wing was mounted after the incident. It is a triangulated tubular aluminum construction.

    I also have a couple sets of CNC aluminum mounts similar to the first design but they require custom mounting plates to be attached to your wing of choice. Email me at will.chan (at)

    I was just wandering about twin charger setups. I have often wandered about it, but just blew off the idea. I was just wandering about some of the issues y’all ran into during the design, and current issues that you may have with boost spike, heat, or any issues you guys may see that’s a direct cause of twin charging your civic. I also wandered would it be fine to use a off the shelf turbo kit like Greddy or should the setup be 100% custom tailored to the vehicle in use. Thanks in advance.

    Hey like your car alot good work this year guys.

    Im here in Kelowna I have the 224 hp same chassis as you also with a Laminova intercooled m45 puting down 160ft. Have you guys thought of doing an intercooler set up for you blower to cool intake temps.

    Are you using a front bar? I have never used one in my car but wondering If I would benfit now that I don’t AutoX anymore.

    I have a very similar set up to you.

    few questions were can I find AST stuff here in Canada? And what rates are you using.

    Im intrested in a wing for my car and a front splitter just wonder if you can share any info on your spliter. and wing setup.

    Wondering what are the Red Line Time attacks like as far as racing. Im looking to do one event next year if I have the money

    We are very limted to Time attacks out west here. Mission race way is very slow and also alot of peaple don’t race cause out here we must run full race gear and at least a roll bar. Not t-shirts and no cages like you guys do for solo sprints out west 😦

    If its in your budget come out to Kelowna to the Knox Mtn hillclimb next year Hillclimb.

    good work guys.

    What are the drivetrain specs and how much have you invested in this machine in total?

    • January 29, 2011 at 6:42 am

      Thanks for the question. We’re using a helical LSD in an si transmission with zc 3-4-5 gears. Stock axles also since we don’t normally launch at low speed or in 1st gear so torque at the wheels is not particularly high. Although the increase in power means that we wear out the cv joints about one set per season.
