vr6 into 89 jetta

i am getting an 89 jetta and want to do a vr6 motor swap due to the 1.8's lack of potential. has anybody done one her and can they give me a ballpark figure on price and what parts i need to get. i really would like to find a step by step guide but cant. if anyone knows of a guide please let me know. my budget is tight so cheap is the way to go. thanks
