Really good thread that tells you prity everything you need to no http://the-corrado.net/forum/viewtopic.php?f=1&t=33931&st=0&sk=t&sd=a&start=135 In short altho i haven't read it all yet what you need is ,R32 engine, VR throttle body, Custom down pipe and manni (£300 ish some company makes them) and then standalone (when going stand alone THINK you can still use mk3 clocks, can't see why u couldn't anyway, You would just need to rewire the Rev counter and oil pressure, rest is still all VR stuff ) Or you can go mad and fit mk4 clocks, engine looms, FBW throttle key
