MHI Stage 2 Turbo Upgrade | Civic Type R (FL5)
The ultimate "no-compromise" turbocharger upgrade for the K20C1. At Chicane Australia, we provide specialised supply for the MHI Stage 2 Turbo Upgrade specifically for the Civic Type R (FL5). Developed by Mitsubishi Heavy Industries—the same team that engineered the factory turbo—this unit provides massive power gains while retaining original mounting points and heat shields. We facilitate fast sourcing and reliable delivery across Australia for this premier bolt-on solution.
The MHI Stage 2 Engineering Advantage
While the factory Civic Type R (FL5) turbocharger is an incredible piece of engineering, it often "falls flat" above 5,500rpm. The MHI Stage 2 upgrade addresses this by utilising a significantly larger 65mm HR3 billet compressor wheel and an enlarged Inconel turbine wheel. Because it uses a genuine MHI centre housing and identical external castings, it retains the lightning-fast spool characteristics and durability of the stock unit, but with enough airflow to support up to 417kW at the crank.
Technical highlights of the Civic Type R (FL5) MHI Stage 2:
• Billet HR3 Compressor: A +7mm increase in diameter (65mm) providing a 33% flow increase over stock.
• High-Flow Turbine: A +5mm larger (52mm) Inconel turbine wheel designed to reduce backpressure at high RPM.
• 100% Bolt-On: Reuses all factory oil and coolant lines, electronic wastegate actuator (EWG), and gaskets for a true plug-and-play installation.
• Tuning Compatibility: Fully supported by Hondata FlashPro and Motec basemaps, ensuring a smooth calibration process.
Based on the Central Coast, NSW, we provide the technical expertise to assist you in selecting the correct supporting hardware to truly exploit the Stage 2's potential in the Australian climate. We work closely with our supply network to ensure your authentic MHI hardware is sourced and despatched with professional care and speed.
MHI Civic Type R (FL5) Turbo FAQ
Do I need to modify my Civic Type R (FL5) to fit this turbo?
No. The MHI Stage 2 is a direct replacement for the factory unit. It uses the original manifold footprint, downpipe flange, and intake connections. You can even retain your factory heat shields for a completely "stealth" OEM look under the bonnet.
What power can I expect on Australian pump fuel?
On standard 98-octane pump fuel with supporting intake and exhaust mods, most Civic Type R (FL5) owners see roughly 300kW to 320kW at the wheels. To reach the maximum output of the turbo, an upgraded high-pressure fuel pump (HPFP) and an Ethanol blend are required.
How quickly can you source MHI products?
We utilise a robust international and local supply network to provide the fastest possible turnaround. Most MHI Stage 2 Civic Type R (FL5) units are sourced and despatched within a short timeframe for delivery nationwide.
