I bought the car about 4 years ago as a completly stock 1999 Integra GS-R. About 1 week later I was already pulling out the GS-R motor in favor of a JDM ITR B18C motor. I modded that motor with a Hytech Header, AEM Intake etc etc to 186whp and 131wtrq. It was nice but I wanted more power.
2 years ago I was convinced to try the K20 route and so it began. Dave one of my best friends and the owner of Defcon-Racing built and tuned the car to what it is today. It made 245whp and 184wtrq on a dynojet.
I took the car to the drag strip last year before all the weight reduction(hood,hatch,rear window) and ran mid 12′s. I was blown away by the time and by the power the K20 made. I have since gotten into my true passion which is Circuit Racing. I run in Ontario Solo Sprints Series in the Super Grand Touring 1 class. Thanks to the help of some great instructors earlier, I ended up winning my class at the first 2 events and came second in my class in the 3rd event. The car is not a daily driver but I do drive it on the street at least once a day and have had no problems at all, it’s been as reliable as a stock car.
I’d like to thank Dave from Defcon-Racing/ART Motorsports for all his hard work, Ming for convincing me to go the K20 route, Kelvin,Lewis and Jamie for helping me so many times, Pat and Joee from Defcon/ART for all their help. John, Baldwin and Ritchie from Optionjdm for all the parts, Barry from Velocity Autobody for the great work on the exterior and of course Will,Matt and the guys from Hybrid-Racing for all the questions they answered, all the great help and parts they provided and for the feature.

Endurance racing is one of the worlds toughest forms of motorsports. Even on a basic level, keeping a high performance car racing full out for a long period of time is a challenge.
