Mine's, the top Japanese GT-R tuning firm, is currently focusing on the GT-R SpecV although it does not claim ownership of the black performance car. Mine's is presently in the process of research on the most expensive Japanese vehicle on the market (worth 15,750,000 Yen or $175,000) which premiered last February 2 in Japan.
The remarkable stock GT-R has received heavy improvements to transform it into a SpecV. It comes with Ray aluminum wheels in black finish with unique Bridgestone high-grip non-flat rubber.
The engine, a VR38DETT, has been tuned although the total power yield is the same. The SpecV comes with a High Geared Boost which boosts the pressure on the turbocharger in real time increasing torque up to 608Nm (62.0kgm). This aims at heightening mid to high range torque.
Other features include a titanium exhaust system that optimizes exhaust resitance plust a fin and rear air diffuser to improve cooling. Vehicle weight was effectively lowered by 60kg (132lbs) by getting rid of all unnecessary amenities like the rear seats and others.
This performance vehicle is fit for the tracks and not for the road. Outside everything is in carbon. What Mine's will do to a car based on the SpecV is anybody's guess, but it's pretty exciting just waiting for it to come to pass.
