It would be cheaper to buy one from another member who is selling theirs...all the work is done for you already. I thought I saw two twin turbo setups for sale in the for sale adds.
Your going to need a transmission for sure...the torque will just eat a stock transmission.
If you don't have any type of locker in the rear, you will need one.
There have been several guys who made twins work with injectors as small as 205's.

Im sure there is alot more...I just don't remember right now.
It's not cheap, or easy if you don't have mechanical experience...if it was, everyone would be doing it.
Mine is a daily driver, but I try to only take it out on sunny, dry days...it will never see winter again...too much money into it, and it would be just plain stupid to try driving it in snow.
