If you want the complete OBD-2 vehicle diagnostic capability, you are going to have to add a whole lot more sensors...
And that's before you even get to the data protocols and all of the other stuff that you need to make things talk to each other.
If you only want fairly straightforward information displayed digitally, it makes more sense to tap into the sensors directly, and have the Arduino display the readings to you. Much simpler that way, though still a fair bit of work.
If all you're looking for is MPG info, then the MPGuino is what you want.

Interestingly enough I already have an MPGuino in my personal car, but that doesn't matter. And if I were to use a CANbus system (at least partially), of which I like the idea, then it'd be completely unrelated to the matters that it relates to when it comes to an internal combustion engine.. as the car will be a 100% electric.
I'm nothing shy of hacking into things and with the help of our electronics guy (sensor specialist at a big company that builds transmissions amongst other things, but he's extremely skilled with all sorts of electronics) I'm entirely sure that we could create our own CANbus network. If I can convince him of the added functionality of a CANbus system of course.
Literally everything in the car will have to be redone anyways, see the car simple as a body with suspension which will also have to be partially modified, I was thinking to bag it for added ('modern') comfort and increased ability to handle heavier loads over stock coilovers which are likely to be (severely) worn out anyways.
