Mine's - Total Balance Experts

Mine's is undoubtedly one of the most famous Skyline GT-R and GT-R tuners in world. This is in no small part thanks to Tsuchiya Keiichi's Hot Version and BMI International car shows where their cars were featured in several episodes. The Inline 6 battles as well as the battle between Mine's R34 GT-R N1 and the Amuse Supra are those we remember the best. But it undoubtedly was the video where Paul Walker visited Mine's which propelled the company to world fame.



Before Niikura Michizo founded Mine's as a motorsport tuning shop in 1985,  he was already tuning cars with off the shelf parts. But when he couldn't find the parts that he wanted for his cars, he started to make his own. The parts he created quickly became very popular and brought him many customers and car enthusiasts like Paul Walker.
The company based in Yokosuka-City, an hour south of Tokyo follows a philosophy based on the principle of total balance and reliability or as Niikura-san puts it: "simple is best". He wanted his tuning to reflect the European way of motorsport tuning, a philosophy that broke away from the then popular "maximum power tuning" that most Japanese tuners adopted. Over years of constant development, Mine's went one stage higher in their philosophy to adopt the principle of ultimate response.

Even though Mine's creates some extremely fast cars, Niikura-san is adamant that his customers understand the what was done to the cars he makes and will adapt the tuning to the knowledge of the individual.

We leave it up to the customer how to modify their car. If we start to do too many things ourselves, we will lose our focus as a company.

We do not want to offer something that the customer won’t understand.

We have our own strict policies on how to modify engines and turbo’s so that we can be as realistic as possible when we develop our cars and parts.
— Niikura Michizo


In its early days, Mine's started where none would have started in the late 1980's. With computers. 

A year into creation, they released their first Fuel Hacker and kept building on the electronics until in 1988 they released their first line of their famous VX-ROMs ECUs for the R31 Skyline GTS-R, setting a number of speed records on the Yatabe test track.

The results were quite astounding. They managed to get a stock GTS-R equipped with their VX-ROM to 245 km/h and a fully tuned version of the Skyline, bored up to 2,2L with a more powerful turbo, to 290 km/h.

At this point in the company's life, Mine's wasn't specialized in Nissan products as they are today. Using their engine management systems, they managed to set an impressive number of speed records for a variety of cars over the years, including the Toyota Soarer,  MR2, AE92 Levin, the Supra and the Honda NSX. In total they took 30 highest speed test trials at Yatabe for just as many different cars.

Mine's then went to develop more parts in keeping with their philosophy. They introduced their ESTA suspension system in 1990 and exhaust options from 1993. From 1995, the pace at which they developed new tuning parts increased dramatically with new products available every year. From aerodynamic and functional carbon parts (spoilers, propeller shafts and clutches) and air intakes to their AP Brake Systems.

However, their biggest break came in 2001 with the release of their complete "Super R" engines.

Since then, their parts line up include VX-ROMs for all Japanese sports car makers, a large variety of intake solutions, complete exhaust systems, a selection of tuned engines from the RB26 to a modified VR38 R35 engine which displaces 4.1L for a max. power reaching over 1000 HP. You can buy this completely overhauled engine for a whopping 57,000 US Dollars.
