The Z34/370Z computer executes complicated electronic calculations and its configuration could not be easily changed like former Z-cars. 
Even the Speed limiterâÅôs function was proven to be difficult to modify. 
We immediately analyzed the Z34/370Z computer that was thought to be too difficult to tune. 
We succeeded in fine tuning the speed limiter controls, the ignition/injection timing, and the Rev Limiter increase. In consequence, we upgraded the response at all revolution ranges that would further enhance the driving experience compared to a stock computer, while still maintaining the drivability and reliability offered by the factory ECU.

We create your VX-ROM based on your factory ECU to retain the original immobilizer function.

The Mine's High Flow Throttle System has increased the diameter of the factory throttle by 2.5mm, and increased the flow area as well as polished its inner surface. Furthermore, it reduces friction whilst retaining the strength and reliability by reducing the throttle shaft thickness to the max. 

Meanwhile, Mine's have further resurfaced and polished the inner surface with ultra precision diamond cutting technology, whilst an ideal Venturi shape has been adopted to the inside of the throttle, and we made it even smoother all the way in.

In addition, the shaft is polished to reduce friction, but strength has been carefully calculated. We also used a special flat screw to minimize flow friction. The more throttle you apply, the more effective it will be.

With superior charging efficiency and inhalation resistance, the vehicle response can be dramatically increased. For ultimate performance, it is recommended to use the Mine's High Flow Throttle System with customize VX-ROM ECU's which we are known for, and this will produce great response.

This ultimate muffler has the extremely quiet and has a comfortable sound. It is user-friendly in the low to mid speed ranges and can maintain smooth drivability in the high speed range. 

It is a powerful even length dual muffler that is not too thick or too thin while the main pipe diameter is φ60Ãó2-φ110Ãó2 particularly in the assembly section at φ80, 

The biggest reason why we used the titanium as the material for rear muffler is because of its lightweight. By doing this, the weight at the vehicleâÅôs rear axis is decreased. Our plan is to contribute to a better performance in cornering stability, acceleration, and deceleration by making this muffler as light as possible. 

We guarantee better power gain by combining its use with Mine's Front Pipe φ60Ãó2-φ80Ôºâwhich we also sell. (You can use the factory front pipe as well with this titanium muffler.) 

Material : Titanium
Main Pipe: φ80-φ60 x 2-φ110 x 2
Exhaust diameter: φ110
Weight for rear muffler: 8kg (Stock: 11kg)

The purification action is now required in the automobile society for environmental preservation. This is the new catalyzer for Z34 which is compatible with the sport engine's performance and also completes the purification action. The stock catalyzer increases the exhaust resistance despite its better purification action because it is authorized as a low gas emission vehicle while its exhaust amount is 3.7L. Mine's Super Catalyzer II, by contrast, has a purification action whilst it decreases the exhaust resistance. 
Furthermore, it increases the power and response at high rpm while reducing the car weight.

The Mine's Front Pipe is designed to have this best inner diameter considering the excessive boost pressures and it is made to maximize the engine power.

Material : Stainless
Pipe Size: φ60 x 2-φ80

--	It consists of a three-layer cotton material, aluminum mesh, and special oil that allows the air to pass through the intake without turbulence.
--	Since there is little intake resistance, the air is rectified and has the appropriate amount of air quantity (1.7 times more than normal) that the VX-ROM requires.
--	Since VX-Air Filters have been developed simultaneously with the development of VX-ROM, their matching is supreme. A VX-ROM user has a feel that is 2nd to none.
--	Since the intake air passes through the same path as a stock intake, the heat in the engine compartment does not affect its efficiency.
--	The filter can be reuse when washed. The percentage of the amount of intake air lost after 35 washes is only 3%. It has proved that it is well within the limits for practical use.

Mine's developed the spring kit that lowered the normal car height, secured a stable comfortable ride, and with the sufficient amount of stroke. It optimizes the stroke at the front by setting the special bump rubber, and at each spring it decreases the unpleasant spring sound by installing the tube isolator.

Mine's original brake pads, designed and manufactured with Winmax, use a low steel material and increase braking performance as well as fade resistance. It allows braking deeper into the corner without wheel lock, but is suitable mainly for street use while reducing brake noise. 
For optimum performance, it is recommended to use these pads with the Big Brake Rotor Kit.

*For installation, modifying the front bumper is required.
*Installation can be done for the factory bumper.

The Z34 Carbon Front Spoiler is fabricated from high quality carbon fiber, and the design of the gurney creates the maximum amount of down force, while it improves cornering performance with high-speed stability without increasing the drag at mid to high speed. 
By slightly lifting the front part design, the installation can be secured even on a low-height vehicle.
