Product Overview
Kelford 272° Camshafts for Mitsubishi Evo 8 4G63 – 8-TX272
Upgrade the breathing capability and high-rpm performance of your Mitsubishi Evolution VIII with the Kelford 272° Camshafts EVO 8 8-TX272.
Developed specifically for the Mitsubishi 4G63 EVO 8 engine, this matched intake and exhaust camshaft set uses an aggressive 272°/272° profile combined with 11.00 mm net valve lift to deliver substantially improved airflow for modified turbocharged engines.
The 8-TX272 is positioned by Kelford as an all-round motorsport camshaft for 4G63 builds producing approximately 400–650 hp. It is particularly suited to cars using turbochargers in approximately the 54–62 mm compressor range, making it a strong choice for fast road, track, drag and competition-focused Evo 8 builds.
Built for High-Performance 4G63 Engines
Increasing camshaft duration and valve lift allows the engine to move a greater volume of air at higher engine speeds. On a properly matched 4G63 build, the Kelford 8-TX272 cams help support improved mid-to-high RPM airflow and enable larger turbochargers to operate more effectively.
The intake and exhaust camshafts both use a 272° advertised duration, with Kelford specifying 226° duration at 1.00 mm valve lift.
For vehicles running upgraded turbochargers, supporting fuelling and appropriate ECU calibration, the 8-TX272 provides a serious valvetrain upgrade without moving into Kelford’s more extreme high-lift cam profiles.
Designed Specifically for the Mitsubishi Evo 8
These are not generic 4G63 camshafts. The 8-TX272 specification is intended specifically for the Mitsubishi Lancer Evolution VIII 4G63 engine.
This is important because Kelford produces different camshaft profiles for earlier EVO 4–7 engines as well as low-lift and higher-lift EVO 8 applications.
For example, 8-TX272-L is Kelford’s lower-lift 10.00 mm version, while this 8-TX272 uses an 11.00 mm valve-lift profile.
Recommended Valve Spring Upgrade
For demanding applications, Kelford recommends its KVS63-BTK valve spring kit with the 8-TX272.
Kelford specifically recommends this spring package for applications running up to approximately 8,500 rpm and 35 psi boost.
Valve springs should always be selected according to the complete engine specification, intended RPM limit, boost pressure and intended use.
Ideal For
The Kelford 8-TX272 is particularly well suited to:
- Modified Mitsubishi Evo 8 4G63 engines
- Approximately 400–650 hp builds
- 54–62 mm turbocharger applications
- Fast road and track cars
- Drag and motorsport builds
- Engines requiring stronger mid-to-high RPM performance
- Builds using upgraded fuelling and ECU calibration
For maximum performance and reliability, professional installation and custom ECU calibration are strongly recommended.

Why Choose Kelford 8-TX272 Camshafts?
The Kelford 272° camshafts for the Mitsubishi Evo 8 are aimed at owners who have moved beyond basic bolt-on modifications and need a camshaft profile capable of supporting substantially increased engine airflow.
When correctly matched with an appropriate turbocharger, exhaust, intake, fuel system, valve train and ECU calibration, they provide a strong foundation for serious 4G63 performance builds.
The 8-TX272 also sits in a useful position within Kelford’s EVO 8 range: more aggressive than the lower-lift 8-TX272-L while retaining a less extreme specification than the higher-lift 8-TX272R.
Installation Note
Camshaft installation is a precision engine-building task.
Before installation, your engine builder should verify:
- Valve-to-piston clearance
- Valve spring compatibility
- Cam timing
- Valve-train condition
- Timing belt and tensioner condition
- Engine RPM limit
- Turbocharger specification
- ECU calibration
Correct lubrication during assembly and regular engine-oil servicing are particularly important for camshaft and valvetrain longevity. Kelford highlights clean oil and correct lubrication as important factors in protecting the camshaft and associated valvetrain components.
