HJA is thrilled to unveil the legendary Sunline Racing R34 GT-R, a car that commands respect alongside other iconic GT-R Heroes such as the Mines BNR34. As one of the most celebrated modified road-going Skylines in the world, this vehicle represents the ultimate dream car for enthusiasts.

In the Skyline GT-R tuning world, Sun Line Racing (SLR) definitely needs no introduction; the Okayama-based shop’s reputation for building hardcore track weapons with an ultra-high attention to detail precedes them. But with this BNR34 demo machine, they took all of their race-car-building knowhow and applied it to a street car.

That’s not to say it was watered down though; the engine produced 720PS at 1.5bar (22psi) of boost pressure, and it managed sub-1-minute lap times around Tsukuba Circuit in full road-going trim. As far as tuned R34 GT-Rs go, this one remains absolute royalty, many years after being built and 10+ years before we managed to find it.

The centrepiece of the Sun Line R34 is its full N1 engine-based build. SLR chose HKS’s 2.8L stroker kit to increase capacity and strength, and then made the most of it with HKS’s V-CAM system in a fully race-prepped cylinder head, a giant Trust T88-34D turbocharger, HPI front-mount intercooler, Nismo plenum, Sard 800cc injectors and custom SLR titanium down-pipe and exhaust among many other upgrades.

The HKS V-Cam Pro is a system that replaces the intake camshaft to offer variable valve timing on the intake side. The system works with the HKS F-Con V Pro engine management system to optimize the power band for a wider range of outputs and not just high power. The SLR team has used the V-Cam system for this purpose with great success.

As impressive as the tuned RB28 engine is, one of the main jewels is hidden out of sight. SLR installed a Hollinger 6 speed sequential transmission. This is known to be one of, if not the best Sequential gearboxes available for the skyline GT-R. The gearbox alone will set you back around £20,000 landed, so it really goes to show you no corners were cut in the production of this epic R34 GT-R.

The stock clutch has been changed out for a 800whp-ready Exedy triple plate clutch, which feeds into an ATS carbon limited-slip differential. While the clutch and gearbox may seem intimidating, they are actually manageable for street use. With practice, drivers can become comfortable using them.

In order to repeatedly and consistently stop this carbon missile, SLR installed a set of Endless Monoblock six-piston front and four-piston rear brakes. Fitted with huge 370mm front and 332mm rear two-piece brake rotors, the Endless callipers squeeze Endless NA-R brake pads and have proven to be fade-free in testing.

For suspension, every arm and rod that could be replaced was done so with adjustable SLR items. The coilovers are even Sun Line Racing’s own specification and provide the perfect dampening settings, set up using hours of trackside research. Giving the R34 balance and control at high speeds, these coilovers allow the heavyweight GT-R to dance like a flyweight and drive like a car half its size.

Outside, carbon fibre is in no short supply. The composite material was used for the bonnet, fenders, boot and GT wing blade – and it was all made in-house at SLR. C-West provided the front bumper (with carbon canards) and Craft Square the carbon mirrors.

As it was built as a road car first and foremost, and despite what the race-ready exterior says, you won’t find a stripped interior inside this R34. Yes, there’s a roll cage, but it’s been neatly integrated so as not to limit entry and exit in any way. SLR chose Bride Gias carbon reclining buckets for the front seating, a limited edition vertex steering wheel, Nismo meters, and added their own custom dry carbon door panels.

Sunline Racing's R34 GT-R is not your average tuned Skyline, and Sunline Racing is not your average tuner garage. Changes have been made to the engine, transmission, brakes, tires, body and interior, but every piece has been engineered and thought out to provide a distinct advantage. So it's no wonder that when you take the mighty Skyline GT-R, and then add in SLR to the equation, you end up with success.
