Hi guys.
My name is Andrew and I'm new here. I would like to ask some questions about building an e38.
I found a 1997 730il with 20kmiles on the clock (probably turned back)

but the car is in awesome shape. The hydrolic suspension have been replaced to a new one and I know the workshop that this guy did it in.
My questions are:
What is the best engine to put in this thing to replace the 3L V8? or is there a kit to bore it up?
If so where is the best place to look for these parts? Engines and etc.
Will the e39 M5 engine fit in this chassis?
Is there any articles that you can direct me to?
Last questions. What is the biggest size wheels can the well accommodate?
Thank you for your advice
Andrew
