Lately we have been showing you what the Japanese tuner Top Secret can do when they want to build a signature one off automobile that changes the way enthusiasts think about cars. Well this is a perfect example of Nagata-san working his magic on a car that changes the way we think about the tuning industry. This is the R34 Nissan Skyline GT-R based Competizione R built for a private customer. Originally the owner wanted a daily driver that could still tear up a drag strip or embarrass the competition on the wangan, but after many years of being a GT-R owner was infected with the track day bug, and the Competizione R once again underwent a complete transformation.

It has taken seven years for the Competizione R to become the dark gray blue pearl vehicle you see before you. While it used to wear a Top Secret body kit, the front end has been replaced with a full Nismo front end. This is made up of a Nismo Z-tune front bumper and flared fenders as well as a Nismo R-tune dry carbon hood while the wet carbon front lip from Top Secret has remained. The side skirts are from Do-Luck and have been molded into the new wings. Out back there is a Nismo dry carbon adjustable lip made to work with the Top Secret diffuser and vortex generator. and the stock GT-R spoiler has been lowered out of the slipstream using a set of custom Top Secret mounts.

The heart of the beast, Nissan’s iron block RB26DETT has been increased in size thanks to an HKS 2.8 Liter stroker kit and in an interesting move, the engine original had a pair of reasonably large GT3037S turbochargers while now it makes use of smaller GT2835Rs for their quicker spool up and ability to make more power down low where the owner wanted it for the track. The little black box in front of the engine is an HKS V-Cam Pro; this system gives the RB26 variable cam control on the intake side, which makes more power at every RPM. The compressed air is fed into the engine through a Nismo GT plenum, the same item that was used on the old R34 JGTC racecars. The package has been tuned to make a much more track friendly 700 HP. Keeping the Competizione R going in a straight line down the front stretch at Fuji Speedway is an adjustable Nitron Pro racing suspension from the U.K. combined with a host of highly adjustable Ikeya Formula suspension links that allow the suspension to be fine tuned.

Continued after the jump.

The Competizione R rides on a set of custom painted 19 inch Volk Racing TE37s wrapped in sticky Bridgestone Potenza RE-11 tires, 275/30/19 same size at all four corners. The front brakes have been upgraded to a set of Brembo 8 pot Ferrari Enzo calipers and a set of 4-pot calipers from a Ferrari 360 out back. However the interior is one of the most interesting aspects of this track day special. The seats have been upholstered in Italian leather with suede inserts as well as for the door cards and shift boots. Everything including the Top Secret steering wheel has been recovered in the fine Italian leather. Quite frankly maintaining the best of both worlds.
