Honda Civic/CRX SiR (90-91) Tuning Packages

Stage 1 Package Up to 5BHP

AEM/Fujita cold air Intake £295 + Vat

Our stage 1 package for the Civic/CRX concentrates on freeing up the intake in order to make your B16 breathe more easily. The addition of a cold air intake provides great gain in combination with outstanding value for money. We have often found that the CAI gives better mid range response than the much more sizeable Mugen intake, which although it delivers marginal top end power gains, is much more expensive.

Stage 2 Package Up to 10BHP

Stage 1 + Exhaust catback (DC Sports Stainless Steel Manifold) From £685 + vat

Our stage 2 is a stage 1 +, it will free up the intake AND the exhaust system, changing the tone of the B16 into a deeper rumble.

Stage 3 Package Up to 15BHP

Stage 2 + Exhaust manifold + decat From£1145 + vat

The stage 3 tuning package for your EK4 concentrates on further improving flow through the engine in order to increase its volumetric efficiency, allowing even greater power gains. To do this we concentrate on freeing up the exhaust path using DC sports products, which provide similar gains to TODA systems, but offering much greater value for money.

Stage 4 Package Up to 20BHP

Stage 3 + remap From £1445 + vat

At Eurospec we can remap your EF using BRE software to develop a custom map for your car. We use your stock ECU that we chip to enable the ECU to run a custom map we’ll make on the dyno.
