What is required to put a 1.6l VW Scirocco GT engine into a 5 speed T25 Crew Cab pickup?

Obviously, I already have the scirocco and the T25, and the original bell housing on the 5 speed box has been swapped for a diesel bell housing as initially a diesel engine was going to be used. I've since decided that the scirocco engine would be a better option as it doesn't look like the car will get through its MOT. Is it just a (relatively) simple bolt in job or will major modifications be needed?What is required to put a 1.6l VW Scirocco GT engine into a 5 speed T25 Crew Cab pickup?Wish I could tell you what;s involved. I can tell you a guy came to our shop last year with a 1.8 turbo in his 87. A shop in Sacramento is doing this conversion. OBD ll and all. The owner loved it. Must be possible!
