What size oil cooler will be suffiecient for a 420bhp turbo engine?
Does anyone reun remote oil filter and thermostat for the cooler?

Whats the capacity of the existing sump and is there a real need for a big wing sump? Is the standard item not up to scratch?

sorry for the q's but im new to the ford scene and wanna know as much about my engine as possible so i can make some informed decisions.

Cheers!
