You know what I bought a Turboed R33 and it was a very nice car to drive and I wish sometimes that I still had it, but after having driven N/A cars for the past 20 years I wish now that I had gone for a nice straight non turboed R33 and just done some of the basic mods like bigger exhaust cams T/B and intake, because every car that I have performed these mods to I have always gotten a very nice driveable car that is cheap on fuel and very easy to drive and very forgiving if you do something stupid - turbo cars are not so forgiving if you do something stupid or even not so stupid
BTW I think you could do far worse than a N/A R33 - great choice
