21) J-Body - vehicle platform in use by GM since 1981 for the Chevrolet Cavalier and Pontiac Sunfire.
22) viscous - a type of limited-slip differential. A viscous limited slip connects the driveshafts of the driven wheels with alternating plates immersed in a thick, snot-like fluid. When all the plates are turning the same speed, the snot is just there for the ride. When one tire slips, there's a speed difference between the plates. This speed difference causes the snot to grab the slower-spinning plates to accelerate them to the same speed as the faster-spinning ones, thus transferring torque to the wheel with grip.
23) Dorifto - "drift" in Japanese slang.
24) Intercooler - a heat exchanger located downstream of a turbo or supercharger which cools the heated, compressed intake air down to reasonable levels, promoting a denser charge and better knock resistance.
25) Aftercooler - despite what your beer-swilling uncle tells you, this is the same thing as an intercooler.
26) Limited slip - a type of differential which, when a wheel slips, allows more torque to be transferred to the nonslipping wheel.
27) Cast - formed by pouring liquid metal into a mold.
28) Magnafluxed - nondestructive inspection method used for detection of surface and subsurface flaws in ferrous parts.
29) Rockford - a reversal of direction done as quickly as possible. While driving in reverse, turn the wheel hard. The front end of the vehicle will pirouette around the rear wheels. As the front end slides around, smoothly engage first or second gear (or put it in "Drive" if you're a slushbox-driving sissy), unwind the wheel and drive away as if nothing unusual just happened. Named for Jim Rockford, fictional L.A. private eye played by James Garner in the 1970s TV show "The Rockford Files."
30) Bar - unit of pressure; 1 bar = 0.987 atmosphere = 14.5 psi = 100 kPa
