hey i own a r32 gts with rb20de its my first car its fairly good on fuel 410 kms on 3/4 a tank highway kms dunno how much out off full tank fueled up b4 but maybe gettin close 2 500 ... ive only had 1 issue were my fuel pump stopped workin but my car has 218,000kms on it but besides that its been real realiable even tho its a 2 litre engine it has alot more go then you would think it would have around 1000-3000 revs its bit slow but after that it good, i picked it up for 6,300 but so far well worth it..
