so heres the situation. i got a sweet deal on a 00 4x4, 4 door, with a 3.3. problem is, the motor has a cracked head, among other various problems. my question is will a 00 xterra motor work? i can only find the 4 cyl. from a frontier. i may be able to get my hands on a 99 frontier v6, but i wont know for a couple of weeks. if i can, is this a direct swap? or did nissan change anything from the 99 to 00? sorry guys, i just got into the truck scene. ive been into bikes my whole life, so i pretty much dont know much about them. thanks
