hi, i have a 1.1l hsc 1990 fiesta, i was looking to upgrade the engine, the 1zt thing i thought to do would buy a new engine but got stuck here. Would a Xr2i or Rs 1800 engine fit in the 1.1 bay.? and would there be alot ofmodifing to the bay.?

 

Engine bays are totally the same. You just need everything out of the XR2i
