Yeah, mine was pretty easy, except for the minor massaging of the driver's motor mount to get it to fit. In the 4th gens I heard it is really, really, easy. I would say it wasn't too difficult, 2 days work with all parts on hand. But use the search button to find useful info, that's what I did. Oh yeah, if you want a good deal on a JDM H22 engine and trans, check out osakajdmmotors.com I didn't get mine from them, but I wish I did. Wow they are cheap, but they aren't shady. I've talked to them for friends, and they are the real deal. Also if you want an auto (like me) their package is like $200 cheaper!!!
