Hey Mate,
Don't know if you have bought your car yet, but i got an R32 GTS 2.0L, and i have to say it's great.
There are some small downsides though
Small engine capacity means you need to keep the revs up for any decent power.
As for drift yeah a LSD would be nice but hard to source, but great in the wet
handeling: as i only have a standard one at the moment i can only go by a standard setup, which is a fair bit of fun but could be a bit stiffer.
Hope this has helped you a bit..
By the way expect to pay a fair bit nowdays as P platers are only alowed non turbo ones, so they are in high demand..
Cheers
