Tuned Integra -- Racetrack test (J's racing)

J's racing, located in the Kansai area where the popularity of Honda is quite high, is well known as a Honda tuning expert. J's racing has modified many Integra from street version to a full race version. Their expertise for setting up a car for a racetrack is recognized as one of the best in the tuning industry. J's racing also researches and develops its original products.

The car brought for this review is the 96 based J's racing Integra race car, you probably have seen it before. The car is based on the 96 Integra which won the Suzuka N1 championship in 1997. It was preserved at the shop after it retired from the N1 racing. The car was in a sense pretty complete as N1 race car. This year, J's racing decided to give it a new life with 2.0. Liter motor and with other latest modifications. The engine block is from S-MX which increases the displacement to 2.0 liter from 1.8. The compression ratio has been raised to 13.1 and it is also equipped with new Tsuchinoko chamber, J's racing SPL exhaust, and original racing computer. It claims 245 hp. Body and suspension are reexamined and tuned for pure race only spec.

A 2.0 liter motor on a pure race car? It sounds "extreme". Plexiglas, FRP body parts, and complete weight reduction. This car is for sure not a daily driver. The weight is only 850kg. An interesting point is that J's racing changed the brake to a smaller one utilizing EK4 brake assembly. The tire size is also same as stock, no increase of the size. This is all based on the total weight of 850kg. A bigger brake and tires are not necessary with a car of this light weight. In addition, a smaller brake reduces the weight further. The best lap time for Suzuka full international course is 2 min 25 sec and 1 min 25 sec at Central racetrack. These lap times are "amazing" for naturally aspirated car.

Impression from a professional driver (Mr. Yamano)
                   "Best matching suspension and tires"
The first impression is "this car is simply fast". The rev limit is 8,500 rpm but with the huge torque equivalent to that of 2.5 liter motor, you do not have to rev it to the limit. There is enough acceleration at around 8,000 rpm. The transmission works very good and the gear ratios are very well fit to the course. It makes me feel as if my driving has been improved. I thought the suspension was pretty stiff based on the setting number provided, but to my surprise, it was not as hard as I expected. That might be due to the light weight of the car and its excellent setting. Even though the tire size is 195, you feel you are driving with 225. The combination of light weight and superior suspension setting make the car fly on the race track.
