About this issue
The August 1999 issue of Young Version explores drift setups versus grip tuning through 22 shop demo cars, including S15 Silvias from Mine’s and Kazama Auto. Features cover front-wheel-drive builds taking on high-powered 4WD rivals, choosing a first drift car, and reviving a used AE86 Trueno on a ¥1 million total budget. Suspension fundamentals, engine-oil selection, rotary maintenance, new-parts tests, and reports from Hiroshima and California round out this look at Japan’s late-1990s tuning scene.

…is a standard established by the American Petroleum Institute (API). As engine performance has advanced, the letter following ‘S’ has moved forward from A; the current top grade is S. The neighboring ‘CF’ is an API grade for diesel engines. On the right, ACEA is the European Automobile Manufacturers’ Association, and A3/B3 are its grades. There are two standards, but API is the one most commonly used.
…is this number. It is the viscosity grade set by SAE (the Society of Automotive Engineers). Simply put, the lower the number on the left, the less thick the oil remains in cold temperatures; the higher the number on the right, the more heat it can withstand. Consumer engine oils generally range from 0 at the low end on the left to 70 at the high end on the right. For example, this oil is 15W-50, a relatively thick engine oil suited to turbocharged cars.
