Hows about work out if you want RWD or 4WD, that will make your choice a bit easier. 32GTR would be they way to go, but then you'll have a 89 model, R33's are sweet and newer, WRX are cheap a good but seems as tho you need to be 40+ to have one! as for Holdens unless it's a Manual V8 don't bother, actually just don't bother with them.
And what about a 180sx or Silvia. S14 would be good.
Good luck with your choice!
