Japan, a Country known for a rich history, honor and culture, after all it is the land of the Samurai. Besides that, in the car world Japan is known for some Gods of the machine world. One in particular in the Skyline GTR. Let it be clear that the current Nissan GTR is often mistaken as a Skyline but it is not…… Nissan only used the R35 chassis name because of the GT-R’s heritage and the GT-R is the current successor to the Skyline GT-R.

The first Skyline was produced in the 50’s by The Prince company. The car was initially marketed as a luxury car. In the 60’s Prince and Nissan merged and they started branding the cars as Nissan Prince Skyline. In 1964 Prince made a GT Skyline based in the S54 and due to its success in Racing, They released the S54 Skyline 2000GT. Closer to the end of the 60’s, Nissan released the first of its historic Skyline GTR in the form of the C10 also known as the KGC10 GT-X. Thus a legend was born. The popular AKA for the Skyline in GODZILLA, because of what they represent. The cost of a Skyline is way less than most supercars and yet they can out perform most of them.

There have been 5 generations of Godzilla, but it was the fourth generation, R33, that Mark Harper by his wings. Harper was a Jet Engine Mechanic in the Air force, The Skyline first caught his attention when he was Stationed in Kadena AB, Okinawa in 2005. His first purchase was a R33 GTST which he immediately started tinkering with. He had the car for about 2 years then he sold it. After extensive research, Mark realised that out of all the generations of Skylines he preferred the R33. Around the time of his retirement in 2008, Mark noticed a white R33 on base for sale. He then met with the owner and ended up purchasing the car. The car was already built, with Ohlins C-ring suspension, Kakimoto exhaust, Apexi Power FC ECU, Nardi steering wheel, n1 front/rear bumpers, Greddy Profec B boost controller, Madori Seibi cams, metal headgasket, 18″ Yokohama Advan TCII gold wheels, which was a good start. In the next few months, with the help of my tuning shop Speed Factory, I made numerous upgrades to get it to the 700hp range. It had Power Enterprise PE1520 TR dual ball twin turbos pushing 22lbs of boost.

Mark eventually sold the car to a guy who ended up blowing the motor. He then purchased the monster and resurrected Godzilla with the help of his friend Doug Payne and Speed Factory. The engine was rebuilt with forged internals which could withstand 1000hp. Zilla was tuned to 700hp while Mark continued to tweak the machine to his liking. He added Ohlins road and track suspension, Alcon 6 pot mono block front and 4 pot mono block rear, Volk Racing TE37 superlap wheels 18″ 10J +20, Tomei Expreme full Titanium Cat back exhaust, Saurus Edition Cross mission, OS Giken 1000F SPL clutch. while doing more research, Mark saw the new Borg Warner EFR 8374 Turbo and he was impressed. Now the vision of a 800hp upgrade was in sight. 18 months later the upgrade began. Mark knew what he wanted for the road and the track. He had Naprec machine a R34 head and installed 10.2 lift 260 degree cams, valve springs and forged valves. Along with the Turbo, Mark installed the Full race twin scroll twin external wastegate exhaust manifold, twin Tial 44mm Wastegates, Nismo intake, 1000cc injectors, twin in-tank 260 Lph fuel pumps, new 3-core radiator with swirl tank, and had it tuned to 30lbs boost (2.05 bar). The car reaches max boost by 4,000 rpms and maintains boost to 8,750 Rpm redline. “It is a monster!” said Mark. “The car is equipped with Altessa all wheel drive system but the current 275/35/18 Dunlop Direzza Z2 tires i have do not give the traction required to safely transfer the new power to the street. I recently purchased an HKS Helical dog mission to be installed during drag events and also 17″ Volk TE37 Wheels with Mickey Thompson street slicks to support the power for launches. My plans for the future of the car are Bride Gias 2 Japan seats, OS Giken Sequential transmission and a fresh coat of paint to finish my build.”
In his own words “I would like to thank my close friend Doug for all his help and expert workmanship, knowledge and close relationship with my Tuners Speed Factory, I could not have done it without them.”
