Thanks for all the replies guys! I will look into all of that. I am getting the car for around 8000.00 canadian. I also consider the engine swap a major change in this vehicle but I trust this person a lot, he has always been there for me and helped me out in the past for free whenever I needed. The primary reason for the swap was to get better milage. I will ask him the full details and get back to you.

P.S. The 4.1 was mentioned by my dad, so I'm pretty sure it was a 4.4 as it usually ends up being like a broken telephone conversation.
