Would bolt into a civic with no problem or any kind off mod would be needed to fit it in?

 

Check the hybrid section. This is covered daily there.

 

I am currently puting a F23a1 into my civic taking out a d15b7 from my research so far...putting a f23a1 into a 92-95 Civic is tricky but not too bad. a f23a1 is from an accord and has A LOT of torque compared to my current engine...the rear and driver's side mount will bolt in but you will have to get an accord transmission (91+) and the transmission mount will NOT bolt in you have to either take off the currrent mount and re-weld it or buy a mount kit (not cheap). you're also going to want to make sure you have an appropriate wire harness. I'm still learning about the mod as well so maybe we can share resources
