Salam everyone.
I need guidance and suggestions regarding an engine swap in my '92 model Honda Concerto. The chassis code is MA2 and it originally comes with a JDM 1.6 ZC/ D16a8/9 engine. The person I bought it from had it changed to a B13, which I want to change.
I want to know which motor could be a comparatively easy swap, without too much modification. And since a lot of time and energy is going to be spent, I want it to be worthwhile.
Someone was selling a K20 and said it should be ok but I'm not sure since...would appreciate any comments on that.
I'd especially request Xulfiqar and other experts for their input!
Pics of the car are attached
