Check out
www.sdsefi.com. I turbocharged a n/a Datsun 280Z once and used one of their systems. It was cheap & very easy to use and program. It comes with a hand held programer so you don't need a PC. There is no datalogging capability however. Even if you don't use their system the website has lots of usefull info.
