Nissan Skyline R34 GT-R reconstructed by JAPO Motorsport - like new

worth every penny!!!! i would buy one in a flat second!!!

That's commonplace with these motors. There are a lot of these monsters running around with over 800hp on the stock bottom end. A friend of mine had an ER34 sedan with an RB26 from a GT-R in it & when he sold it that thing was making over 600whp all day every day with minimal mods. Didn't even break a sweat.

You do have a point, but remember, that is the RB26DETT, the well-known powerplant sooooo tuneable that it made the GT-R famous for that. Stock car does 280ps, but you can get 400ps with only a chip change. This is no ordinary engine. We're not talking about 200hp per litre on an NA engine. These figures are really piece of cake for this engine.

Thanks Douglas6250. It may sound strange to him, but ask anyone in the know. The stock R34 was rated at only about 280 hp, but in reality dynos proved it was closer to 330-350. With an intake, exhaust & a boost controller, 400hp is easy. The stock turbos have ceramic turbines & that's the weakest link, but swap the turbos & intercooler (the stock FMIC is at it's limit at just over 400whp... seen it on the dyno myself more than once) and you're just begining to scratch the hp surface. I had an Evo IX that I modded the hell out of (1000cc/min. injectors, Walbro in tank 255lph pump and FPR, ARP head studs, Cosworth 280 cams, complete Ferrea valvetrain, HKS head gasket, AMS turbo kit with GT35R Turbo, PWR intercooler, Tial 50mm blowoff valve and 44mm wastegate, Tilton twin disc clutch, AEM EMS & running 28lbs of boost... 509whp, well mannered & daily driven, stock bottom end) and my friend's skyline made more hp with waaay less mods, & absolutely nothing done to the bottom end on it either.

well i accept that you can push 200bhp per liter without touchin bottom end, but other modifications isn't so minor.

Well, whether you want to admit it or not, it doesn't make it any less true. A turbo + intercooler swap is a very minor mod in my book. Anyone mechanically inclined could do it on an RB motor in a couple hours. I've swapped several turbos in my backyard. I find it amusing that you're trying to say that a few bolt ons are major mods... but since you're hell bent on being a skeptic, don't take my word for it: do yourself a favor & look up RB26DETT, & Skyline GT-R. You'll find plenty of them (in Japan & Australia especially) that are making the kind of power I'm talking about with very minimal mods. You'll find photos, build sheets & dyno runs to prove it.

Actuallu i think its a stroked RB26DETT to 2.8L like the Z-Tune, but not using the original Z1, 2.5 might be a typo

all you need to know is that the conversion unit from hp to ps is 1.014!
