Initially, I was quite suprised with the power generated from the engine at 1.2bar of boost pressure. Coming in at 220rwkW (Power FC untuned) and leaving at 292rwkW (after tuning) is a bloody big gain in anyone's language; the sort of power you would normally only see from RB26DETT engines with upgraded turbos and cams. Therein lies the rub. The R34 GT-R engine in stock form is able to prodice a bag more grunt than a similarly modified early-series engine.

Nissan made a fair bit of noise at the time of the R34 GT-R Skyline's release about the new generation of Garrett ball-bearing turbochargers. They were, of course, only ever designed to add much needed torque to the engine. Nothing to do with power, as Nissan was not about to break the gentlemen's agreement about limiting power to 206kW. The bottom line is that the R34 turbocharger is almost a spitting image of R33 GT-R N1 unit, with the bonus of a ball-bearing core.

Unbeknownst to most is the difference between R32 and R33 GT-R turbochargers. There are differences not so much in the exterior housings, but in the compressor wheels and in turn the dump pipes, which allow a stock-turbo R33 with bolt-opn mods to make significantly more power than its R32 equivilant. Both of these versions cary the handicap of ceramic turbine wheels, though. Whereas 1.2-1.3bar of boost pressure on the R34 turbochargers is a 'gimme', the wise tuner keeps the boost under 1.1bar on the early models and leave it at that.

Can't help you on the pricing for used turbos, but you owe me big for sitting down and typing out that section of the article.
