    So your car is a 1997? Do you mean you got the engine from a H reg MR2? I meant what was the original donor car (assuming it's a Camry).

    If it's a 3vz the engine came out of a car 1991 - 1993 ish, so it should be MOT'd as a if it was pre 95 which is a no cat test.

    Well it's not like it came in the car, and any mechanic could tell you it's not a modern engine.

    Do you have any documentation from the original donor?

    And if not would you like a copy of one? I may have a couple. The engine block won't match of they check (obviously) but you could always say it was rebuilt.

    :)
