The base car is 2001 Nismo N1 Super Taikyu GT-R that has been completely reworked by Top Secret. Some of the major stats include:
Top Speed - 198.4mph (320km) at 8500 RPM with HKS transmission (Max Power Mag reports 210mph max)Power - Dependent on setting, currently 728 HP / 488 ft/lbs for time attack setting. Peak 854hp Weight - 1300kg / 2860lbs (770lbs lighter than stock)0-60: 3.1 seconds (est by Max Power Magazine)
This vehicle was built by the renowned Japanese tuning workshop Top Secret and has been used as a promo car for several years. It has spent very little time on the track as it has been used primarily for display purposes at motor shows, and has only been run at official racing events to prove the package. Everything is in perfect working order. This vehicle has had literally hundreds of thousands of dollars spent on it. One of the fastest and most well known Skylines in the world and a very rare find.
Performance: Has recorded a 9.6 second 1/4 mile on Yokohama 048 racing tyres. MAX POWER: 1000ps / 9000rpm. MAX TORQUE: 90kgm / 8000rpm. 
One of the most famous cars made by Top Secret was this GT300. It's not powered by the 2JZ but gets its horsepower from the much lighter 3S-GTE engine. ‘Smokey' did this to improve the power to weight ratio and the balance of the car.
The capacity of the 3S-GTE engine has been increased thanks to a Garage Fukui Stroker kit and SPL pistons. The turbo of choice is the Trust T88 34D, giving the engine 710bhp at 8500rpm and 470lb-ft of torque at 7800rpm. Those are some impressive number considering it's ‘just' a four cylinder engine.
Top Secret knows how to build engines. They started with a bare SR20 block and enlarged the displacement with a HKS 2.2 liter kit. For the turbo they went with a modified HKS 3037PRO-s. A Tomei camshaft ensures that the throttle response is nice and fast. The exhaust manifold is a one off made by Top Secret. The engine pushes out 550ps
Cooling is also a major issue with drift cars; they always go sideways so it is very important to get as much cooling as possible. Top Secret went with a V-mount setup and used three electric fans. ARC provided the oil cooler and the triple core intercooler.
For the fuel system they went with SARD 1000cc injectors and fuel injector. Top Secret also added an extra fuel pump and fuel delivery pipe to the front of the car.
Smoky has been a busy man! This is the recently completed Top Secret R35 GT-R, wearing the new 2012 GT-R inspired front bumper and the signature gold color everyone knows and loves. The car made its first appearance at the 2010 R's Meeting this past weekend in Fuji Speedway, hinting that Top Secret has gotten serious about the R35.
The engine has been fitted with a pair of re-engineered stock IHI turbines which are modified and ported to flow more air and fitted with a 22% bigger turbine wheel. The built in wastegates are also enlarged and controlled by fast-acting GReddy actuators. At 1.25 kgf of boost the motor manages to develop 700 HP with a massive 651 lb/ft punch of torque at 4,000 rpm.
The Top Secret Supra project is intended to present the Supra as the kind of supercar some feel Toyota should be selling. Its V12 powerplant is sourced from a Toyota Century (a Japanese market luxury sedan), and extra power beyond its stock 276 horses, many airflow aids have been added. These range from custom plenums and piping to dual HKS GT2540 turbochargers. All in all, the engine's output has been tuned somewhere north of 1,000 hp.
