noooooooooooooo
ok your new so ill be lenient
what you are talking about is what this website is alllll about
google 4age rwd conversions and youll get a billion websites with alot of information
look for bill sherwoods page, its great.
in short
all 16V's bolt up to a t50 gearbox.
the RWD jap intake manifld will fit on all bigport 4ages (86 or 96kw)
the wiring of a 4age is simple, and only takes a bit of studying the wiring diagrams. it wont plug into your car, but it will be quite easy to get working (like 4 wires)
technical problems? not really. its all bolt in when you get the right bits.
good luck
