Time to get to the real meat of the latest race spec Nissan GT-R to be spied out of Nismo’s workshop. We got our first look on Saturday and fortunately, GTR-World were quick enough with their camera to snap a whole load of pics.

In this final installment of the photo posts, we get under the hood and inside what we presume is the upcoming ST1 specification Nissan GT-R for Super Taikyu competition next year.

Firstly lets check out the tyres on this beast, we can quickly see that these are no street tire and a full slick is fitted. It’s actually a prototype Yokohama Advan A005 265 wide (front) tyre in 20 inch size. Yokohama’s largest commonly available size for this tire is 18 inches so one wonders if this tire will be sold through dealers in the future or restricted to use by Nismo.

Next let’s check out the interior. While much is stripped out and a serious roll cage bolted in, several standard road car items can be spied. A Sparco racing wheel replaces the standard wheel but much of the dashboard, cluster, stalks and paddles remain stock. Carbon blanking panels replace the vents and stereo and climate controls are of course completely replaced with functional carbon panels to bolt more robust controls into. A Recaro Pro Racer SPA HANS carbon kevlar seat with Willans harness keeps the driver in place.

The MFD and navigation control surround piece is also replaced with proper carbon fibre. At first thought I guessed this was from the SpecV model but in comparison you can tell they’re nothing alike. The SpecV carbon MFD surround panel was too heavy for the race car? Or is this a preview of parts that may make it into future road car versions?

Under the hood we’re greeted with a pretty ordinary looking VR38DETT engine. A few obvious updates include:

• Custom catch can
• Blanking plates where blow off valves were
• Removal of emissions / evap control systems
• Billstein fully adjustable suspension (Thanks Martin)
• Custom radiator overflow tank
• Custom power steering fluid sock
• Custom brake fluid resevoir sock
• MOTUL engine oil replaces Mobil 1
• Lightweight battery with emergency cutout
• Upgraded fittings

There’s also a hidden power steering cooler in front of the radiator and a lack of aircon.

That’s pretty much it from me on the subject, I’ve strained my eyes enough for one day. Feel free to post in the comments if you spot anything I missed first time round. Enjoy the rest of the photos!
