Yeah like a14force said it`s not that difficult. See `My Photos`.
Mounting was as simple as fitting an alternator (the AMR300 is off a Subaru Vivo 660cc and most Jap importers/wreckers sell them for no more than $200) with a few spacers needed to line up the custom made crank & blower pulleys (which were made by a pulley manufacturer here in Sydney). Use an early model 1200 alternator bracket to mount the blower to the block (slight grinding needed to bolt hole in bracket to make it fit).
Then to get all the piping flanges laser cut, then get a good mate to make all the bendy pipes to make it all fit.
But if I were you I`d ditch that cam you have canefarmer, and lower the comp to at least 8.5:1. ( I used 2x Monotorque head gaskets & cc`d the chambers). To optimise performance you really do need a blower grind cam ( something with no more than 112deg lobe separation angle )
One more thing don`t forget to toss the 4speed box , I munched mine in the first week! I now have a Sunny 5speed (200kmh EASY!)
Good Luck with your build
ps: This might give you some basics even though most of the info is based on V8`s
