    Default 205 Gti and Mi16 parts interchangability

    Hi all,

    Before I make a decision to purchase an mi16 for an engine conversion in my little pug I would like to know what other parts if any I can make use of from the mi16 on my 205.

    I am sure this has been asked previously but I searched and cant find it.

    Thanks,

    Gearbox, this will give you a 4.43 final drive although the gears are a little more widely spaced from
    2nd onwards. You can build a hybrid using Mi16 1st and 2nd and final drive and 205 GTi 3rd 4th and
    5th. This gives you a close ratio box with the lower final drive.
    Can't think of anything else, the brakes won't fit.

    There's really little of use out of an Mi16 other than engine/gearbox which are mostly well past their due date. Just buy an XU10J4R from the wreckers and ask Adrian Wuillemin to build you a gearbox.

    What si the cost of such a motor, I need one for my 205 given the MI16 is getting old. Gearbox is interesting the 205GTi always needed a longer 5th so that may need investigation, ie will help as well.

    David Cavanagh was selling them for $500 recently, which is about what they're worth given the value of a 306. Why would you want a longer 5th?

    Could be a stupid question but what car is this out of and is the conversion on par with the mi16 conversion in terms of difficulty that I have read so much about?

    Has anybody done this conversion and have a registered example? Any problems with vicroads or any engineers certificates etc?

    Thanks

    Not sure of the outcoem of a MI16 box but I am after a longer range 5th, the revs in the my series one are far too high for cruising. The longer ratio change with the MI16 will help so I am not sure of that outcome.

    Have a look in my 8V build thread. There is a listing of a ratio setup for 205gti

    Halfway down page 2 I think.

    The Mi16 box is similar to the early 205 box for cruising in 5th.
    You want an 205 Si box or better still a series 3 205 GTi box.

    F/D is 3.94, same as early GTi.
    Don't know about the ratios but probably as for 8 valve 405 except for lower first gear.

    No, closer to an XS but with an XU engine.
    A much more civilised car to drive on the road, still pin sharp in the steering and as I'm finding out, better for dirt competition than the GTi.
    I should add that my competition Si has a leaded 1.9. close ratio Mi16 box, Nolathane suspension bushes and group N strut tops, engine and rear subframe mounts.
    Suspension is standard Si except for Koni yellows in the front and stock GTi in the rear.

    Th Si ratios are completely different to any of the other aussie 205's. I have the ratios at home and will dig them out.

    The 1.6gti has a 4.06 diff ratio. Will dig these ratios out also

    Dont want to upset the rest of your conversation but if somebody could just let me know what car this engine come from then I will then just sit back and read all of your posts about ratio's etc which I am not ready for just yet.

    The cases from them are the best ones to use. They let you use an MI16 flywheel etc but are a lighter case than the MI16 box.

    They also usually have a easy life. Therefore the synchros / shift mechanism etc is in better condition.
