Tech Info

We have seen many Skylines that have unwanted engine knocking problems due to the octane differences between Japan and North America.

Why ?

In Japan, it is possible to obtain an octane of 100 from regular gas stations. But unfortunately, in North America, the highest octane available is about 94.

Due to the combusting lower octane, most of BNR32(GTR) (especially the ones that boost up create engine knock), can possibly damage parts of the internal engine. If the engine knock is not made on the Skylines' engines, the ECU will still read the regular fuel map. And this situation does not offer sufficient power.

Thus, to overcome this problem, we offer ECU fuel re-mapping for 94 octane and unique ignition timing.

Re-mapping includes all the limited-cut. Altering REV limit is optional.

We also tune ALL Japanese fuel management systems (sub & full con), such as Trust(Greddy) Apexi, and HKS.

A short history on the Skyline GT-R

In August 1989, the Skyline range was the the most powerful GT-R model -- revived after a 16-year break (chassis # BNR32). Since the first generation PGC10 model was launched in 1969, the Skyline GT-R established a brilliant record of success in numerous motor sport events as a high-performance machine representative of Japanese automotive technology.

The power train feature of GT-R wasa RB26DETT 2.6 liter inline, 6 DOHC with twin ceramic turbochargers and a large intercooler, ATTESA ET-S, which controled all wheel drive systems electronically. It also had HICAS, a four wheel steering system. The ATTESA ET-S optimally controled the torque distribution to the front and rear wheels according to the driving conditions. It significantly improved vehicle controllability while cornering.

Yaw rate feedback control was adopted to the phase reversal control procedure in Nissan's Super HICAS four-wheel steering system. This control procedure enhanced vehicle stability on rough roads and while traveling at high speeds.

The bonnet and front fenders were made of aluminum, achieving a weight reduction of approximately 12 kg compared with panels made of steel. At the rear a large sized spoiler creates down force at high speed. Japanese Touring Car Race (JTCR)

On March 18th, 1990, GT-R (chassis # BNR32) made its dramatic debut at the Nishi Nippon circuit. This was the second time that the legendary Skyline GT-R had made a name for itself, until 1993, when the regulation was amended. Since the first race, the GT-R held the pole position for the entire series, achieving the best lap-time, resulting in 29 consecutive wins.
