GTR-World: Mine’s High Flow Throttle Body Report

June 24, 2009 Comments off


As seen recently in an interview with Mine’s president Niikura-san, Mine’s has been developing engine parts for the Nissan GT-R and GT-R SpecV with a goal to improve the power and, more importantly, the response of the VR38 engine. Mine’s tuning philosophy has always been one of modest power goals with maximum response.

One of the differences noted by Mine’s when they got their hands on the new SpecV was that Nissan had paid some attention to airflow through the SpecV’s standard throttle body. To smooth flow through the intake they have coated the rough cast inside of the throttle body. The result you can see below. In comparison with the standard item it’s an improvement but when you see it next to the Mine’s item you can see how doing it properly would be preferable.


Mine’s not only pay attention to machining the inner surface of the throttle body but also to the aerodynamics of the butterfly valve and control shaft.


The Mine’s High Flow Throttle Body is available now through your local Mine’s distributors. For a pair of throttle bodies in exchange for your standard ones, the price is 132,000 yen. For a pair of throttle bodies without exchanging your own the price is 258,000 yen.

GT Channel: Mine’s Boss Niikura-san on New Generation of Tuning Parts and Mine’s SpecV

May 5, 2009 Comments off

GT Channel have had a long friendship with Mine’s and Niikura-san certainly seems to love their cameras. They recently hit up the Mine’s HQ in Yokosuka, Japan to check out what the Mine’s guys have in the pipeline and what their plans are for the new Nissan GT-R SpecV.

As discussed in the video, probably some of the most exciting news which we have touched on previously, is that Mine’s are indeed developing a full engine upgrade called the Mine’s Super Complete Engine. We’re now aware that Mine’s will be shooting for about 600ps peak power but that, in the Mine’s tradition, the power will be delivered very early and in a very responsive manner.

Mine’s have always been about maximum response at modest power levels. That was powerfully evident in the Mine’s R34 GT-R of days gone by. Now by utilizing Mahle forged pistons and titanium I-beam conrods they plan to lighten and strengthen the VR38’s internals to be stronger and more free revving. They’re shaving off more than 300g per cylinder with just these mods.

The second video (after the jump) goes into great detail on the mine’s Super Big Throttle Body coming soon also.

Thanks to Taro from GT Channel for the heads up!

April 13, 2009 Comments off


In a recent statement, Mine’s CEO and President, Michizo Niikura-san has announced a confirmation of further developments on the Nissan R35 GT-R platform. Mine’s has been committed to developing products for GT-R enthusiasts since launch back in 2007 and most recently showed off their Mine’s Spec-X 6.0 GT-R representing the then pinnacle of their parts catalog.

Next up from Mine’s according to Niikura-san’s statement are releases for the 2009 (Series II) GT-R and the SpecV GT-R. ECU’s for both have been unlocked so expect updated VX-ROM releases in the very near future.

Outside of that, Mine’s is also working on their throttle body upgrade for the GT-R known as the “Super Big Throttle Body”, more carbon fibre products to enhance the aggressiveness of the GT-R’s looks, and finally, a VR38DETT Super Complete Engine upgrade featuring upgraded pistons and conrods among other things.

More on these new parts as news comes to hand.
