    Default 1984 2.5 engine

    Anyone know or know where I can look to find which car bodies a 2.5
    engine from an 84 Celebrity will fit?
    Thanks

    Not sure I understand the intent here. Do you have a good engine/bad
    car and want to put your engine into another body? Or, are you looking
    for another engine to put into your Celebrity?

    At any rate, the 2.5 (AKA Iron Duke) has been used in many GM vehicles
    starting in the 60's with the LeMans. It was also used in Jeeps and
    boats over the years. I KNOW that it was in an '80 Phoenix that I had,
    and it probably was also in the "sister" cars -- Cutlass Ciera and
    Chevy Citation.

    HTH,
    Mark

    I have an 84 Celebrity with only about 60K miles on it in excellent
    shape. The body is rusting away (under the seats, brake lines, gas
    line, etc.). Someone told me the motor would only fit 84 & 85
    Celebritys. I've looked for several years for a decent body with no
    luck.
    However, I have found an 88 Cavalier with no rust and would like to
    swap the motor if it will fit.

    They never put the 2.5 "Iron Duke" into the Cavalier. The Cavalier had
    the 1.8,2.0 and then 2.2, 2.8, 3.1 V6, Quad 4 in the Z24 version etc..
    You could probably put it in a Cavalier but would require extensive
    modification of motor mounts and such. Best to find a car that
    originally came with the 2.5, but has a great body and bad engine for
    cheap.

    The 2.5 was the base engine in the Chevy Celebrity, Pontiac 6000, Olds
    Cutlass Ciera, Buick Century (these cars are virtually the same car).
    It was even the base engine in the Camaro for a few years, Pontiac
    Fiereo (they should have used the Quad 4!), GMC Jimmy, Blazer/S10, Grand
    Am, even Postal delivery Jeeps, etc.. I think of all the cars that the
    2.5 lived in, the Pontiac 6000 was the best styled of them all. Real
    cool car. Neat styling, interior, dashboards.

    here's a ton of detail on the Iron Duke. GM probably used the Iron Duke
    in the Pontiac Fiero because they also used the front suspension bits
    from the Citation/Phoenix/Omega cars in the Fiero! They basically took
    the FWD engine/suspension from the Citation clones and placed them in
    the back of the Fiero! More GM bean counting. But I still loved the
    Fiero and used to own one. A silver '84 SE model with the Iron Duke.

    Thanks for the Wiki link. I really never realized that the 2.5 engine
    that was in the old 60's Tempest was NOT the same as the Iron Duke.

    Interesting,

    Another thing to know about that later engine is that it tended to be a
    piece of Sh**.

    I had one in a Fiero too. Block cracked early on, and when I went to the
    junkyard to
    find a solid block to rebuild, found roughly 4 of 5 also cracked in the
    exact same place.

    Another great conquest of GM over the trusting proletariat.

    Huh? The iron duke was a good engine. The s10's with it run over 200k
    easily without problems. I overheated mine when the radiator blew, it
    melted a piston but kept on running.

    Not all of them were, Eugene. In that era, 1984, a large number of them
    self
    destructed with cracks in the water jacket just above the lifter gallery
    floor.

    Those were bullshit engines. I went through enough of them in the junkyards
    to know.

    Maybe they fixed them, or maybe they were good previously, but there was
    a period that these engines were purely trash.
