If he is just using it untill january y build the engine that much??You will have to go with a better clutch to hold that much horsepower and it will b a huge pita to drive for a daily.Traction will also become an issue after 300whp.iv been in a few turbo hondas 300+hp and from 60rolls there blowing the tires off.plus if you can hook 250whp should be good for atleast a mid 13 i would think with there curb weight.It would also be able to be driven daily but still haul some ass.
