ye rhd sell em for like, half the price of nissan. could prob get em off the auctions if we needed also. montana, the s15 turbo is a GT28R anyway, would notice little difference going to an RS, especially as most RS models you can buy dont last very long for some reason (odd occurance with them). The stock '15 turbo will be fine for upto around 320bhp, depending on associated mods and mapping, which is the same as the s14 turbo, its just not a BB core on the '14 model. its fine though, me and rick are gonna bolt on T67's and T88's, RRFPR, be fine mate ^;
