  • Acronyms

    Well, its pretty late and im really bored, so i thought i'de do something usefull for a change. So I'm starting to compile a list of acronyms and definitions for the newcomers of both drifting, and the automotive world. To help try and educate them, seeing as though some can't be bothered to search for themselves, or maybe they don't know exactly what to search for. They might type in LSD and instead get a bunch of sites on the drug . I'm not going to include chassis codes on specific cars because their are just too many. Feel free to add and please don't hesitate to correct me of any mistakes...

    P.S. I do not encourage the consumption of lysergic acid diethylamide or any other illegal narcotics...

    I've Posted links to this information before, but i thought it would be more convenient if i just put them here. Those links can be found here

    Nissan Engine Code Breakdown

    The first letter(s) signify engine family, the numerals that follow explain the engines displacement. The suffixes at the end explain any additional features.

    Note:These are suffixes
    E- Electronic Fuel Injection
    D- Dual Overhead Camshafts
    T- Turbocharged
    TT- Twin Turbocharged

    Toyota Engine Code Breakdown

    The numbers at the beginning signify the age of the bottom-end design (ie the larger the number the newer the design). The letter(s) after this number then identifies which engine family the specific engine belongs to. The suffixes at the end explain any additional features.

    Note:These are suffixes
    E- Electronic Fuel Injection
    F- Economy type engine with narrow angle head
    G- Dual Overhead Camshafts
    Z- Supercharged
    T- Turbocharged (either single or twin)

    Mazda Engine Breakdown

    From what i can see, Mazda does not use a specific engine classification method, rather, their engines are named according to that design. I will just list the names of the rotary engines here, for more information on Mazda engines feel free to visit the link provided earlier.

    12A- Early Model Twin Rotor Wankel Rotary
    13B- Later Model Twin Rotor Wankel Rotary
    13B-REW - Later Model Twin Rotor Wankel Rotary Sporting Twin Turbos
    20B- Triple Rotor Wankel Rotary
    RENESIS- Twin Rotor Wankel Rotary. The name is derived from 'Rotary Engine' 'Genesis'

    Honda Engine Code Breakdown

    Honda's method of engine classification is rather simple. First letter(s) signify engine family, numerals then show engine displacement and suffixes signify engine generation.

    Note:These are suffixes
    A- First Generation Engine
    B- Second Generation Engine

    ----------------------------------------------------------------------------------

    This is only what i could remember right now, there is so much more out there, but your not doing any good asking the most basic of questions here. Please do your own research before asking a question, educate yourself. Good places to start are Google or the auto section at How Stuff Works .

      Thank you

      I've also decided to include an explanation on a few engine codes. Even though I should be asleep by now. 2:48am

        Pretty good, amazingly a simple thing that no one has done.

          i'll assume that VLSD is a variation of the LSD then? i recall nissanguy writing something about it in his overview on the s13 chassis.

            That is correct. VLSD means Viscous Limited Slip Differential and is generally used for grip applications. How it achieves this, I'm not too sure myself. However, an explanation can be found here.

                  I've seen this on the subaru owners fourm, they had like...ten pages of stuff... but yea good looking out for posting this to those that dont know.


                  Also I've asked alot of people who i think know alot about cars and suspension, none know what the $%^# Yaw is, could somone please enlighten me?

                    An explanation of what Yaw is can be found here . Yaw is generally a term used in aviation. It is the horizontal rotation of an object along its centre of gravity. So its basically just a fancy term for turning.

                    An explanation of how the AYC works can be found here . The AYC works as an electronic torque splitter, distributing torque to the desired wheel. It's purpose is to enhace better grip and steering responese whilst driving through the bend itself. In an understeering condition, the inner wheel would be given more torque and the outer wheel given less for a better turning rate.

                        This is helpful for newbies like myself. Since I'm in the "New to Drifting" forum, can someone tell me what a 'hachi' is?

                              I dont think your right about the honda engines. My dads crv has an 18b but its a 2.4 liter. i dont think the number means displacment. they have an explanation of yaw in gran turismo 2 actually. YAW generates rotational movement by controlling the distribution of torque between the left and right drive wheels.
