what your looking at doing is potentially illegal, you can't legally put a motor in a car thats older then the car, if you have an 04 you can't put a 95 motor in that car it has to be an 04 or newer, thats why no one has done a street legal swap

so after some research, apparently theres been a few 3SGTE swaps on the xB. i'm assuming the C150 fits just fine on it, i havn't been able to find someone actualy saying it does but i havn't read anything about having to use a diffrent trany or trans axels.

i emailed toyota about it aswell asking if the C150 and or C160 mounts to the 3SGTE at all and what would be needed to do so if theres any modification needed.
