Sounds like you have a clear plan in your head which is good. Lots of info and knowledge on here so feel free to ask. Obviously try and search first but don't be shy to ask!
First turbo car eh!? It's not too much of a mystery and is nothing to be feared. By the sounds of it I imagine you will be doing most of the work yourself? I would reccomend the Motorbooks Turbocharging Performance Handbook...
A useful guide to how turbocharging works and some good advice/examples. Well worth it IMHO.
Look forward to hearing about your progress....even if it IS an R33
