    So I decided to do some hunting on what the Toyota engine code "1GR-FE" really stands for.

    1 - 1st Generation (2 denotes 2nd generation, etc)
    GR- Engine Series Code/Engine Family (Dual letters started being used for Class/Family series)
    - (following the dash refers to engine details)
    F - Narrow valve angle, economy oriented engine (as oppose to G for wide valve, performance oriented engine)
    E - Electronic fuel injection

    More Code break down info

    AFTER the hyphon:
    A - Valvematic variable lift intake head
    B - Twin SU-style side-draft carburetors
    C - Carburated / California Emissions Controlled
    D - Twin Downdraft carburetors
    E - Electronic Fuel injection
    F - Economy narrow-angle valve DOHC
    G - Performance wide-angle valve DOHC
    H - High compression like 9.8:1 (example: 5E-FHE) / High pressure charged (example: 2L-THE)
    I - Single-point fuel injection
    J - Autochoke (Early models) or unknown pollution control
    L - Transverse
    M - Philippines' market (meaning unknown)
    N - CNG fuel
    P - LPG fuel
    R - Low Compression (For 87 and below octane fuel)
    S - Swirl intake (1980s)
    SE - Direct injection (1990s)
    T - Turbocharged
    U - With Catalytic converter Japan-spec emissions
    V - Common Rail Diesel Injection (D-4D)
    X - Atkinson cycle (typically also indicates a Hybrid engine, as Toyota only uses the Atkinson cycle with hybrids)
    Z - Supercharged

    Supposedly same family motors should have interchangeable parts.

    So based on this naming convention:
    -Supercharged Tacomas = 1GR-FZE
    -Turbo'd Tacomas = 1GR-FTE

    -quoted from http://en.wikipedia.org/wiki/List_of_Toyota_engines
