I am now 25, but as an undergrad I spend all my money converting my n/a z31 to a turbo and then spent the rest of money on intercooler kits, bigger injectors etc etc...problem is the car was left at home in my garage all the time and I drove my wrangler at school. Made no sense. I do it now with my Z32TT, but atleast it works perfectly and I use it 50% of the time as compared to never. Beer and women are far more important when you are 18-22 in college. But if you have spare funds and time, do it, but do it right or you will regret not just waiting and selling it and buying a real TT.
