Why are you planning on buying a 1.8 clutch and flywheel? Why specifically Exedy? The 1.6 clutch and flywheel are lighter and are the OEM parts on your car.
Are you planning on boosting your car one day or keeping it naturally aspirated?
You should consider buying a clutch that can support some power, regardless of whether or not you go boosted.
I'm running a 1.6 clutch and flywheel in my '94. If I ever decide to boost my car than I have more than enough torque capacity with my setup.
