Eventuri V3 Oversized Carbon Turbo Tube for Honda Civic Type R FK8

The Eventuri V3 Oversized Carbon Turbo Tube is a performance-focused turbo inlet upgrade developed specifically for the Honda Civic Type R FK8.

Designed to reduce restriction between the intake system and turbocharger, the V3 tube features significantly greater internal volume than the original Honda turbo inlet while maintaining a smooth airflow path through its one-piece prepreg carbon-fibre construction.

It is available in two versions:

Complete V3 Turbo Tube Kit

SKU / MPN: EVE-FK8V3-CF-CHG

Choose this option if:

• Your FK8 still uses the factory Honda turbo tube
• You are buying an Eventuri FK8 turbo tube for the first time
• You require the complete installation hardware

V3 Tube-Only Upgrade

SKU / MPN: EVE-FK8V3-CHG-UPG

Choose this option only if:

• You already own an Eventuri V1 FK8 turbo tube system
• You already own an Eventuri V2 FK8 turbo tube system
• You want to upgrade to the latest oversized V3 carbon tube while reusing compatible existing Eventuri hardware

Important: The EVE-FK8V3-CHG-UPG tube-only version is not intended as a complete installation kit for vehicles still using the factory Honda turbo tube.

Larger 78–88 mm Internal Diameter

A major difference between the Eventuri V3 turbo tube and the original Honda inlet is internal volume.

The Eventuri V3 tube starts at approximately:

78 mm internal diameter at the intake side

It then expands to approximately:

88 mm through the main body

The standard FK8 turbo inlet measures approximately:

63 mm internally

At its widest section, Eventuri states the V3 design provides approximately 96% more cross-sectional area than the OEM turbo tube.

This substantially reduces restriction in the airflow path feeding the turbocharger.

Improved Turbo Response

Reducing inlet restriction allows the turbocharger to draw air more efficiently.

Eventuri reports that the larger V3 tube allows the turbo to reach peak boost sooner while reducing the load required to maintain boost.

This can be particularly beneficial during lower-RPM acceleration, where improved spool and response may be felt more clearly than a simple headline peak-power figure suggests.

The benefits become increasingly relevant on modified FK8 Type Rs where the turbocharger is demanding greater airflow.

Eventuri Performance Testing

Eventuri independently tested the V3 turbo tube at Dream Automotive using an FK8 with Stage 1 calibration.

With the same ECU map and intake system used for back-to-back testing, Eventuri reports:

Peak gain: approximately 9 hp
Peak torque gain: approximately 9 ft-lb
Gain below 4,000 rpm: up to approximately 15 hp
Torque gain below 4,000 rpm: up to approximately 18 ft-lb

Eventuri reports that the previous V1 tube produced approximately 4 hp over the OEM tube at peak RPM, while the V3 generated a further approximately 5 hp at peak RPM.

These figures are manufacturer test results and are not guaranteed for every vehicle. Actual gains depend on ECU calibration, intake system, exhaust system, turbo specification, ambient conditions and supporting modifications.

High-Temperature Prepreg Carbon Fibre

The Eventuri V3 Turbo Tube is manufactured as a one-piece prepreg carbon-fibre component.

Using carbon fibre enables Eventuri to create a smooth internal surface and gradual curvature through the inlet path.

This contrasts with the original cast-aluminium Honda tube, which has a comparatively rough internal surface.

A smoother transition helps reduce unnecessary turbulence as air travels towards the turbocharger.

Reduced Heat Transfer

The turbocharger is one of the hottest components in the FK8 engine bay.

Rather than attaching the carbon tube directly to the turbocharger, Eventuri uses a precision-machined turbo flange connected through a silicone coupler incorporating a thermal spacer.

This separates the carbon elbow from direct contact with the hot turbo housing.

Carbon fibre also has lower through-wall thermal conductivity than the standard aluminium inlet tube, helping minimise heat conduction into the turbo inlet tract.

Ideal for Standard and Tuned FK8 Type Rs

The Eventuri V3 turbo tube can be used on standard-output FK8 Type Rs, but its increased airflow capacity becomes increasingly useful as engine airflow demand rises.

Suitable applications include:

• Standard road-going FK8 Type Rs
• Stage 1 ECU tuned vehicles
• Stage 2 tuned FK8s
• Performance intake-equipped cars
• Upgraded intercooler installations
• Sports catalyst or downpipe-equipped vehicles
• Performance exhaust systems
• Higher-boost applications
• Fast-road builds
• Track-day cars
• Modified K20C1 engines

For higher-output FK8 builds, reducing pre-turbo restriction can become particularly valuable.

Premium Carbon-Fibre Engine Bay Upgrade

As well as increasing airflow capacity, the Eventuri turbo tube provides a significant visual improvement to the FK8 engine bay.

The prepreg carbon-fibre construction pairs especially well with Eventuri carbon intake systems and other carbon engine-bay components.

Which Version Should I Order?

Buy EVE-FK8V3-CF-CHG if:

Your FK8 currently has the factory turbo tube or you have never previously fitted an Eventuri turbo tube.

This is the complete V3 installation kit.

Buy EVE-FK8V3-CHG-UPG if:

You already have an Eventuri V1 or V2 FK8 turbo tube system fitted.

This is the V3 carbon tube-only upgrade and allows compatible components from your previous Eventuri installation to be reused.

Important

Do not order the tube-only upgrade simply because it is cheaper.

If your car does not already have the necessary Eventuri V1/V2 components, purchase the complete kit.

FAQ

Does the Eventuri V3 turbo tube fit the Honda Civic Type R FK8?

Yes. The Eventuri V3 turbo tube is designed for the Honda Civic Type R FK8 equipped with the 2.0-litre turbocharged K20C1 engine.

What is the difference between EVE-FK8V3-CF-CHG and EVE-FK8V3-CHG-UPG?

EVE-FK8V3-CF-CHG is the complete V3 turbo tube kit for new installations.

EVE-FK8V3-CHG-UPG is the V3 carbon tube-only upgrade intended for customers who already own an Eventuri V1 or V2 FK8 turbo tube system.

Which version should I buy if my Civic Type R still has the factory turbo tube?

Buy EVE-FK8V3-CF-CHG – Complete V3 Turbo Tube Kit. This version contains the additional Eventuri installation components required for a new installation.

Can I use the EVE-FK8V3-CHG-UPG tube-only version on a standard FK8?

Not as a first-time installation. The tube-only upgrade is designed for existing Eventuri V1 or V2 turbo tube owners who can reuse their compatible Eventuri installation hardware.

How much larger is the Eventuri V3 turbo tube than standard?

The Eventuri V3 starts at approximately 78 mm internal diameter and increases to approximately 88 mm through the main tube. The factory tube is approximately 63 mm internally. Eventuri states that this provides around 96% more cross-sectional area at the widest section.

Does the Eventuri FK8 V3 turbo tube increase power?

Eventuri reports approximately 9 hp and 9 ft-lb peak gains in its testing, with gains of up to approximately 15 hp and 18 ft-lb below 4,000 rpm. Actual results will vary depending on vehicle specification and tuning.

Do I need a remap after installing the Eventuri V3 turbo tube?

Eventuri does not state that ECU calibration is mandatory purely for installation. However, a suitable ECU calibration can be beneficial on modified FK8s where increased airflow capacity is being used alongside other performance upgrades.

Is the Eventuri V3 turbo tube suitable for tuned FK8 Type Rs?

Yes. Reduced turbo inlet restriction becomes increasingly beneficial as airflow demand rises, making the V3 particularly suitable for Stage 1, Stage 2 and other higher-output FK8 builds.
