300ZX points as address above,
Silvia... just go a S14 or better - better brakes, wider track, 5 stud etc etc
R32, realistically if your coming from muscle, go the GTR, or an RB25DET GTST (converted 32, or 33 etc)
My stockish 32 chops virutally anything (bar more modified GTRs), let alone when you throw a bit of money at them.
If its a weekend ride 100% undoubtedly go the 32 GTR, otherwise you will have to make compromises for a daily, that said my 32R is my daily...
Have a look at for sale section and car import sites like www.imports101.com.au to get an idea of what you can get for your $$$
