You are talking about a 'twin turbo swap' - that would involve major surgery on a 24 year old car, in the case of the Nissan - why on Earth would you want the hassle, heartache and absurd expense of attempting this?
A Subaru Legacy is a long wheelbase Impreza, with four-wheel drive and very good stable road-manners in all weathers. I have a FANTASTIC Toyota MR2 mark2 Revision5, which is one of THE most tractable, even-tempered and incredibly sharp-braking cars available at any price, anywhere. Yours for a bargain price, and plenty of tuning potential and improvements available. I bought mine when there was snow and ice everywhere, and controlled it on the drive home just fine.
I would recommend a mustang or corvette over those but out of those two I would get the Nissan. Mitsubishi is Crapsubishi.
Mutsu motors has been on the edge of bankruptcy for the last five or six YEARS, and just took the #1 spot on a list of cars that the owner's would NOT recommend to their friends.
whatever one uses less of the earths ancient oils!
I want either a Nissan 300 zx non turbo 1990 or Mitsubishi 3000gt SL 1995. Which one would be good for snow and different weathers. Which one is faster when I do a twin turbo swap and smooth drive. So pretty much which is the better car.
