Product Overview
Pipercams Mitsubishi Evo Cam Kit KBMITS320 – 320° Race Camshaft Upgrade
The Pipercams Mitsubishi Evo Cam Kit KBMITS320 is a high-performance race camshaft package developed for Mitsubishi Lancer Evolution IV, V, VI and VII models powered by the turbocharged 2.0L 4G63 engine.
Designed around Piper’s BP320 race camshaft profile, this specialist performance kit provides increased valve lift and an aggressive cam timing configuration intended to support demanding high-RPM engine builds.
Unlike a basic replacement camshaft set, the KBMITS320 package includes additional valve-train and installation components to support a comprehensive camshaft upgrade.
Whether you are building a competition-focused Mitsubishi Evo, preparing a track car or developing a highly modified 4G63 turbo engine, the Pipercams KBMITS320 offers a serious valve-train upgrade for experienced engine builders.
Why Choose the Pipercams KBMITS320 Cam Kit?
1. Race-Specification 4G63 Camshafts
The Piper BP320 profile is classified as a Race camshaft.
Its manufacturer-published specification includes 272° advertised inlet and exhaust duration, together with 12.00mm of valve lift on both sides.
The higher valve lift and extended timing characteristics can help support increased airflow at higher engine speeds when matched with suitable engine modifications.
This aggressive specification is intended for competition-oriented applications rather than an otherwise standard daily-driven car.
2. Improved High-RPM Engine Breathing Potential
The Mitsubishi 4G63 is well known for its tuning potential.
As power targets increase and turbocharger systems are upgraded, the factory camshaft profile may become a limitation to high-RPM cylinder filling.
The Pipercams KBMITS320 cam kit is designed to support greater airflow potential through the intake and exhaust valves.
Its benefits depend on the complete engine specification, including turbocharger sizing, cylinder-head flow, exhaust system, engine management and correct cam timing.
3. Matching Valve Springs and Caps
High-lift camshaft profiles place greater demands on the engine’s valve train.
The KBMITS320 kit includes Piper valve spring components and caps to support the intended camshaft installation.
Correct spring selection, installed height and mechanical clearances must be checked during assembly.
4. Adjustable Vernier Cam Timing Components
Accurate camshaft timing is particularly important on modified turbocharged engines.
The kit includes Piper vernier pulley components, allowing camshaft timing to be set by an experienced engine builder.
Correctly established timing helps the engine operate as intended for its chosen turbocharger and ECU calibration.
5. Timing Disc and Camshaft Assembly Lubricant
Piper supplies timing and installation accessories with this package, including a timing disc and assembly lubricant.
These support the installation process and help the engine builder correctly establish valve timing.
Always use the latest manufacturer instructions and verify the exact kit contents before fitting.
Pipercams KBMITS320 Camshaft Specifications Explained
The camshaft profile features:
- 272° advertised inlet duration
- 272° advertised exhaust duration
- 12.00mm inlet valve lift
- 12.00mm exhaust valve lift
- Hydraulic valve clearance specification
- Piper BP320 race application
The BP320 designation identifies Piper’s camshaft profile. It should not be mistaken for a measured 320° advertised duration.
The profile is intended for high-performance and motorsport applications with suitable supporting modifications.
Mitsubishi Lancer Evo 4, 5, 6 and 7 Compatibility
The Pipercams KBMITS320 is listed by Piper for Mitsubishi Evo 4–7 applications.
The relevant vehicles use versions of the 2.0L turbocharged 4G63 engine.
Compatibility must be confirmed against the exact engine, cylinder head, valve-train arrangement and any previous modifications.
Different camshaft kits are offered for Evo 1–3, Evo 8 and Evo 9, so those versions should not be treated as interchangeable with KBMITS320.
Is the Pipercams KBMITS320 Suitable for Road Use?
This is an aggressive race camshaft profile.
Compared with a mild road camshaft, a race-profile design may result in rougher idle characteristics, altered low-speed torque delivery and greater requirements for ECU calibration.
It is best suited to a properly prepared high-performance or motorsport engine rather than a standard road vehicle.
Installation and Engine-Building Requirements
Professional installation is strongly recommended.
Before fitting, the engine builder should verify:
- Valve-to-piston clearance
- Valve spring installed height and suitability
- Coil-bind clearance
- Valve-train condition
- Camshaft timing and pulley setup
- Timing belt and tensioner condition
- Hydraulic follower condition
- Engine RPM limit and turbocharger configuration
- ECU calibration and fuelling requirements
Incorrect camshaft timing or insufficient mechanical clearance can cause serious engine damage.
