i not askin much infact toyota you could make this car for about the same cost as the xB. Why don't you shortin the xA to a 2 door and take out the 1.5 liter motor and in its place put the 2.4 liter tC motor. You may whan to change the front end to look like the tc If you guys want to.

 

The 2.4 liter won't fit in there. Not even close. Plus it would make it really front heavy and throw off the handling.

How about a turbo 1.5 instead. Toyota already makes one and it's good for about 150 hp.

In fact they already make a 2 door turbo Yaris, or at least they have offered it in the past in some markets unless I am mistaken.
