    I am looking to swap an engine from a 94 SL2 DOHC AUTO Tranny into my
    94 SL2 Manual Tranny. Does the enginer match up after replacing the
    torque converter with the fly wheel???

    Any hints or issues to look out for would also be appreciated

    With the auto trans, there's a plate that bolts to the crankshaft which the
    torque converter then bolts to. Make sure you don't use those bolts to
    secure the flywheel to the crankshaft. Use the ones made for the manual
    trans flywheel because they are slightly longer than the ones from the auto.
    Unfortunately, they're easy to mix up if you've tossed all your bolts in one
    bin but that length difference is important.

    I don't know why Saturn just didn't use the longer bolts for both auto and
    manual in the first place... I suppose they had to save that nickel.

    Have fun with your swap.

  3. Flexplate should, in theory, absorb a lot of the loading, and in any
    case, the shock loads are lower in an automagic. Then again, it would
    have been cheaper to just use/stock one bolt size...

    Sometimes GM's quest to shave a cent goes to absurd lengths...

    I dont think GM had a say for something that wasnt their design...

    Automotive engineers need job security, right? Why do you think
    there are multitudes of different sizes of parts like light
    bulbs, wipers, alternators, etc?

    Take incandescent light bulbs, for example: They're pretty much all 12V
    with standard brightness requirements. So why are there so many
    different ones?

    I'm sure that the difference in length has much more to do with
    clearance issues!
