pretty good...ASI 52mm dual core alloy radiator can be had for 180$ on ebay new and will do they job just fine, fits nicely too....run 300kw through mine without issue...just keep the stock engine fan don't go electric
The rims will fit fine ,I have 17x7.5 and 8 inch V35 rims +30 with 235/45s all round and oddly enough they do scrub on the inner front guard liner quite alot,.which is easily removed anyway........But my enkeis 17x8 and 9 at +38 with 245/40 and 255/40 race tyres dont scrub at all despite being wider...stock rim size is 16x6.5 +40 i think..
power steering cooler wouldn't go astray, but the 33 gearbox is one of the toughest around try get a good one to start with, keep the oil fresh and invest in a good clutch it should give you many years of trouble free motoring...
people seem to complain about them being front heavy and the engine is a bit of a lump, but the battery is already in the boot and the AC removed will make a big difference, this also allows better airflow cooling to your turbo.....Some decent front brakes would be high on the priority list once you get moving, but the stock ones do ok too start with, just getting some braided lines, decent brake fluid and a master cylinder stopper makes a huge difference.....
