if its a mk1 engine...its bolt on...not a single alteration needed.....
secondly fuel pump just an electric 1 as i m using in my car..no issues at all
super charging a stock engine will be the worst option ..unless u dont care about the engine life.....just few runs
unless u can find a sprint turbo engine G10 3 cyl..which were designed for turbo..and were factory fitted turbo
