x20xev what power can the handle???
whats the maximum bhp and torque the can handle befor things brake?
whats likely to give up first?
what about a close ration f18 gearbox what power can that take?
and what about the cluch?
most power ive known one to have is 197 with no problems
dont really see why they wont handle major power though
maybe consider arp rod bolts though and a steel head gasket
and gearbox i wouldnt bother with an f 18 my mates been through 2 of em running standard power
best use an f 20
