““It takes three generations for a restaurant to perfect the taste of its dishes” — Kozo Watanabe, founding father of the modern GT-R”
Nissan was close. The BCNR33 project was hugely successful, the chassis was more refined than the R32, and it performed better in every aspect. Nissan knew the R34 had to be the ultimate. The R33 had beaten the R32 around the twisty Nürburgring by 21 seconds, and although the engineers knew their newly developed R34 wouldn’t beat the R33 by the same margin, it was to be quicker under any conditions. Seven seconds quicker around the gruelling circuit — Nissan had built the ultimate production car.
Emil Roshan became a GT-R enthusiast the same way a lot of us did, through motor sport, and is currently on his third. His first, a midnight-purple R33 GT-R V-Spec, was completely factory bar a set of Enkei NT01s, but was unfortunately taken from outside his home in Auckland — a fate plenty of Skyline owners are all too familiar with. Not wanting that to happen again, Emil purchased a pink R33 GT-R in the hope that it would not get stolen. This backfired, as when it came time to sell it there weren’t many who were after such a colour — but eventually the pink body-kitted R33 was sold. “I’ve always wanted an R34 GT-R, and one day I was down at ST-Hitec when I saw this example. The owner was keen to sell it, as he had spent too much on it and was also worried about it getting stolen,” Emil told us.
His build closely resembles the values of Japanese-based tuner Mines, as Emil opted for the ultimate in response. A large single turbo was never on the cards, and neither was ethanol. Instead, a pump gas everyday kind of supercar that could be beaten on at the track and driven home is what he was after. To achieve this goal capacity had to increase, so an N1 block was sourced, along with a swag of Tomei internals, including the elusive and exclusive Tomei 2.8-litre counterweight crank. Tomei cams measuring 280 degrees with a 10.80mm lift combined with a ported head and adjustable Tomei cam gears were installed to give the GT-R the widest powerband possible — the aggressive, lumpy idle was a byproduct.
Response comes thanks to a combination of things. Increasing capacity can bring boost on quicker, improving response, or simply installing more-efficient ball-bearing or even billet turbos can have a similar result. Emil opted for both. The now 2.8-litre block feeds a pair of GTX2863 turbos, which sit on ported factory manifolds. Tomei manifolds were in place, but would crack every track day, so off they came. Originally boost was pushed and sucked through an HKS induction kit, but it was found to limit power levels. A GReddy induction kit — which separates the two compressor outlets until much further down the intake system — was installed, and improved boost response by around 500rpm, and Soichi managed to pick up another 20kW on the dyno.
After riding shotgun in the R34, we can assure you it has almost factory-like boost response, yet yields over twice the factory power output, with 428kW at the wheels on 26psi of boost.
Because the R34 is black, it does a great job of hiding some of its special exterior modifications. The Top Secret carbon-fibre bonnet replaced one the previous owner had installed, which they found to be heavier than the stock item — the new bonnet is so thin, it’s see through. A Nismo front diffuser initiates the perfect under-body aero, and the rear Top Secret diffuser keeps the R34 stable at speed.
The GT-R did have Work Emotion XD9s, however, after installing his 360mm two-piece Biot rotors and caliper spacers, he found they didn’t bolt back up. Braking was then further improved with 350mm 370Z rear rotors and Project Mu 999 brake pads. The 18- by by 10.5-inch Rays Volk Racing CE28RT wheels are shod in Falken FK452s for street use, and Nitto NT01s for track days. After searching locally for these wheels, Emil ended up grabbing a plane ticket to Australia to collect them, to save some coin. As the wheels weighed in at just over his allowed carry-on, Emil dragged them onto the plane, avoiding darting looks.
Emil’s GT-R is the perfect all rounder. It runs on pump fuel, has a DVD player to enjoy on long trips to the numerous Taupo track days he attends with his wife in tow, and features a very trick suspension and brake package. Although not the most powerful GT-R in this GT-R mega feature, it is by far the most refined — just as Kozo Watanabe and his successful GT-R engineers intended.
