I'm with you there. Who wouldn't!
Although:
You may need to be a little more detailed in your request. What is decent power to you, 250kw or 900kw?
What other mods do you want to go along with it?
Are you looking to spend 25k or 80k?
If your budget is around 40, I'd import an decent 92/93 model and build a motor for it, or get a crate 3.2+ stroker from RIPS or SPOOL or someone similar. Or build a 26/30 yourself!
Or do you want a stock gtr that has 25+psi being fed into the high mileage 2.6 (with 80k's on the clock lol) with the only thing holding it together the upgraded head studs. Easy to get 350kw's out of one..Might last a month, might last years. Mine kept on keeping on! No idea how the rust kept the body together.
There are a couple of track ready Bnr's on Car Sales, and a GunGrey one with a big single and a blown motor. From memory a couple of decent single turbo GTR's were for sale up near Townsville, not sure if they are still there you would need to filter through the search function in this forum as they are not on carsales.
A couple of the 32's on car sales I'd stay well away from, unless you have a rust fetish..then by all means. Same goes if you chose certain importers...
If a 400 +/-kw single turbo Gun grey GTR that was owned by a forum member with a detailed build blog pops up in that 25 to 30k bracket, there will be a deposit on it before you can open the forum. So be quick, and good luck with your search.
Oh another option is, get a wad of cash out and go to one of your local SAU events or meets...
