From where I come from(East Malaysia), the A31 is the only car that is still readily available.Hardly if not never, heard of the 260RS..hehehe... Furthermore, I know most of you dudes here use the A31 for drifting but I'd like a sleeper with an RB26 and 4WD in it(straight line beast). As for the 4WD system, I think I'd forget about all the wiring hassle and opt for the Veilside or APEXi torque split controller...unsure how much they cost though.
Speaking about cost, I can keep the labour rates low as I deal with many workshops almost everyday who can give me good deals.Furthermore, I do have my own mini workshop at my backyard(my dad's also an enthusiast).
If I see a huge possibility of converting the A31 into an RB26DETT/4WD beast, I'll set aside some $$ for it to happen sometime soon. What's holding me back is the modifications to the chassis that is needed to fit the gearbox/ATTESSA system(wider) as well as the front suspension and front subframe/crossmember to clear the moving parts..
FYI, the A31's price over here stays at around AUD 15k. How much is it over there?
