Want this question answered?
Well it really depends which scion you're talking about. Most Acura Rims are 5lug 115mm bolt pattern but everything except the Scion TC are 5lug with 4" (or 100mm) bolt pattern so they definitely not fit. For starters I'd find out what your lug pattern is, you find find it by going to places like http://www.originalwheels.com/acura-wheels/index.php to find the sizes of the acura rims you're looking to swap with the scion rims.
No they can't. The best you can do is 18"
They will but I wouldn't put them on, it too big size for this car, it will destroy your steering and suspension systems.
They will only fit with minor modification. Scion TCs' bolt pattern is 5 x 100. BMW uses a 5X120 bolt pattern. Only way for it to work is to buy 5x100 to 5x120 wheel adapters. You can find them on eBay for about 30 bucks a wheel
yes
Yes, however scion rims will not fit on hondas without machining the center bore
No
no the 1993 acura integra headlights will not fit the 1995 integra, 90-93 acura integra are more of a rectangle shape as to where in the 1994-2001 integras except the type r, have round head lights
NO! 17 wheels do NOT fit a corsa
Definitely. You can fit any engine size into a scion as long as you have the cash to make some modifications, which is going to be very expensive.
Gears are wheels with teeth that fit together.
Yes, It will fit a 90-93
