Honda FN type R gets supercharged.

The Honda Civic Type R, whether in JDM or Euro spec, is famous for its howling, rev hungry i-VTEC engine, which makes trips to the redline so addictive. But when faced with turbocharged Euro hot hatches, the Honda driver will need a lot of hard work and commitment to keep pace due to the relative lack of grunt. Forced induction might be the answer, as suggested by Torque Developments (TD).

The tuning house developed three levels of supercharger upgrades for the 197 bhp 2.0-litre K20AZ3 i-VTEC engine that powers the European Civic Type R hatchback. The conversions are based on a proven package produced in the US by CT Engineering, which has required revisions for right hand drive installation, plus the reworking of major components to ensure optimum fit and performance.

The Stage One supercharger was designed to work with the stock air intake and exhaust system, and is a straightforward bolt-on “Roots-style” kit that requires no modifications to engine. This low pressure (4-5 PSI) unit includes a Hondata ECU reflash to optimise ignition and fuel settings plus a carbon fibre fuel rail cover.

Meant to provide “linear boost”, Stage One adds a healthy 75 bhp (to 272 bhp) and bumps torque from 193 Nm to 258 Nm. Weak low end pull is one of the CTR’s weak points; with 90% of max torque available from 3,500 rpm things should be much improved. It costs £4911.50 in the UK, and comes with a 12-month/50,000 km warranty.

Stage Two builds on the above, with the addition of a smaller supercharger pulley to increase boost pressure by a further 3 PSI, larger fuel injectors and extra Hondata ECU remapping, which raises the FN’s rev limit to 8,500 rpm. In addition, a choice of Mugen, Toda Racing or HKS induction kit is “advised” for better performance. Adding 95 bhp (to make 292 bhp) and 85 Nm (to 278 Nm), this kit costs £5955.75.

Stage Three is the same as Two, but with an even smaller pulley for an additional 1 PSI. This ultimate CTR provides 302 bhp and 285-292 Nm of torque to play with. Now that the Honda’s front wheels need to handle significantly more grunt, TD suggests some parts to “retain the cohesive nature of the driving experience”. Cost options include a Wavetrac LSD, Fast Road suspension geometry set up, lowering springs, adjustable coilover suspension and exhaust systems from Toda or Mugen.
