using a front cut and replacing all belts, tensioners, water pump, new clutch, rear disc's, efi fuel lines, efi tank, associated wiring and odd and ends that will be needed ie oils and coolant. i would say be round the $6000 - $7000(including price of cut)thats if u do all the work ur self
or then there the option of buying a converted corolla for bout the same price.
the down side of both options is that u never know what the engine has been treated like before u get it.
but another down side for the cuts is that it getting harder to find low km cuts (not that they don't exist just harder to find)
mind u the price i said is just an estimation from a few guys that have performed a few of these conversions.
anyways mate goodluck with ur decision either way :)
