Product Overview
Pipercams Mitsubishi Evo 8 Cam Kit KBMITS8320 – BP320 Race Camshaft Upgrade
The Pipercams Mitsubishi Evo 8 Cam Kit KBMITS8320 is a comprehensive race-profile camshaft package engineered for Mitsubishi Lancer Evolution VIII models equipped with the turbocharged 2.0L 4G63 engine.
Built around Piper Cams’ aggressive BP320 Race camshaft profile, the kit is designed for competition-focused and heavily modified Mitsubishi Evo 8 engines where improved high-RPM airflow and precise valve timing are important.
Unlike a basic replacement camshaft set, the KBMITS8320 package includes supporting valve spring and adjustable timing components, making it a comprehensive option for specialist 4G63 engine builds.
Whether you’re preparing an Evo VIII for circuit racing, drag competition or a high-power turbocharged engine project, Piper’s BP320 cam kit provides the valve-train components needed for a serious camshaft upgrade.
Why Choose the Pipercams Mitsubishi Evo 8 Cam Kit?
1. Race-Profile Camshafts for the 4G63 Engine
The KBMITS8320 kit features the Piper MITS8BP320B camshaft profile, which the manufacturer classifies as a Race application.
Key figures include:
- 272° advertised inlet duration
- 272° advertised exhaust duration
- 12.00mm inlet valve lift
- 12.00mm exhaust valve lift
- 224° inlet and exhaust duration measured at 1mm lift
These specifications make the BP320 a more aggressive option than the milder BP270 and BP285 profiles.
Important: BP320 is Piper’s profile name. It does not mean the camshafts have 320° advertised duration.
2. Supports High-RPM Performance Potential
The Mitsubishi 4G63 turbo engine is widely used in performance tuning and motorsport.
As turbocharger size, boost pressure and power targets increase, valve timing and airflow become increasingly important.
The Pipercams Evo 8 BP320 profile is designed to support high-RPM cylinder filling in an engine built with appropriate supporting components.
The result depends on the complete specification, including cylinder-head airflow, turbocharger selection, exhaust system, fuelling and ECU calibration.
There is no universal horsepower gain guaranteed by the camshaft kit alone.
3. Matching Piper Valve Spring Kit Included
The KBMITS8320 includes the Piper VSSMITSK valve spring kit.
Piper specifically warns that the BP320 camshaft is unsuitable for standard original-equipment valve springs.
The upgraded spring package helps provide the appropriate valve-train support for the more demanding cam profile.
Correct installed height, spring pressure, coil-bind clearance and valve-to-piston clearance must still be verified during assembly.
4. Adjustable Vernier Cam Timing Components
Accurate camshaft timing is essential for extracting the intended performance from a race engine.
The kit includes Piper vernier cam pulley components, allowing an experienced engine builder to set cam timing precisely.
This is especially valuable where the engine uses modified pistons, cylinder-head work, a different turbocharger or a custom engine management calibration.
5. Timing Disc and Assembly Lubricant Supplied
Piper includes a camshaft timing disc and camshaft assembly lubricant with KBMITS8320.
These help support correct installation and initial assembly.
The engine builder must follow the manufacturer’s installation requirements and appropriate engine-building procedures.
6. British Performance Camshaft Engineering
Piper Cams manufactures specialist performance camshafts for road, rally, race and other motorsport applications.
Its Mitsubishi Evo range includes several camshaft profiles designed for different operating requirements.
The BP320 configuration is intended for serious competition-style engine builds rather than routine road-car replacement.
Pipercams BP320 Camshaft Specifications Explained
The Piper BP320 uses equal advertised inlet and exhaust duration of 272°, together with equal 12.00mm valve lift.
Greater valve lift and longer duration can increase the engine’s potential to move air at higher RPM when the rest of the engine is appropriately matched.
However, aggressive camshaft timing can also influence idle behaviour, vacuum characteristics, low-speed torque and emissions.
For that reason, the KBMITS8320 is most suitable for owners building a highly modified Evo VIII with professional mechanical and tuning support.
Mitsubishi Evo 8 4G63 Compatibility
The Pipercams KBMITS8320 is listed specifically for the Mitsubishi Lancer Evolution VIII 4G63 engine application.
It is relevant to suitable Evo VIII variants with the appropriate cylinder-head and hydraulic valve-train configuration.
Before ordering, confirm:
- Mitsubishi Lancer Evolution VIII model
- 2.0L turbocharged 4G63 engine
- Correct cylinder-head and camshaft configuration
- Existing valve-train modifications
- Piston-to-valve clearance requirements
This part number should not be assumed interchangeable with cam kits for Evo IV–VII, Evo IX or Evo X.
Is the Pipercams KBMITS8320 Suitable for Road Use?
Piper classifies the BP320 as a Race camshaft profile.
A competition-style camshaft can affect everyday driveability, particularly at lower engine speeds.
Its aggressive characteristics make it better suited to a properly engineered high-performance or motorsport vehicle than an unmodified daily driver.
Professional ECU calibration is strongly recommended.
Professional Installation and Engine-Building Requirements
Camshaft installation is a precision engineering task.
Your engine builder should verify valve-to-piston clearance, spring compatibility, coil-bind clearance, hydraulic follower condition, timing belt condition, cam timing and the intended engine RPM limit.
Incorrect installation can cause severe mechanical damage.
Consult the official Piper Cams technical data and installation instructions before fitting the kit.
