If you like to mess with a N/A then by all means go for it..........
But If you should like to have a faster car... Buy a 951.... it is already made to go faster and it does........ but hey it is your money....
A N/A is a good learning car, and a 951 is a good wrench car. both take some skill to keep running to perfection
If you take a good long look at both cars there are so many things that are made to handle more power on the 951 it is alomst a waste of time and money to go the N/A to turbo route...
while your thinking about rebuilding your N/A for the turbo you might want to replace your cam and the head with Turbo parts, and get some Turbo injectors, also it might be a good idea to plumb in the Turbo water cooling pump that runs after engine shutdown, but that should not be too hard only an extra few lines and few relays, i have an intercooler and an intake manifold i could sell you
