I talked to builder who said did need. Its a honda and they will hold up. One even said no point to run an oil cooler in a 124se motor. it will be interesting to hear them chime in though...removing the clutch is so simple though its 4 screws and the clutch nut. Its the fact you have to remove the whole top end and drill out the oil pump hole that feeds from the cylinder/head to the pump itself or theres no point in the HV oil pump as it wont squeeze through the hole...
