    Throttle bodies

    can anyone tell me if there is a difference between a Z20LET throttle body, and a Z18XE one? are they any different, and are they interchangeable?

    IIRC they are the same internal diameter - 58mm

    But they are different fitting - the Z18 has a round neck for the inlet pipe to connect to (jubilee clip), whereas the ZLET has four bolt holes for the top hat fasten on.
