124k mile stocker is still pushing along. But I know it's a matter of time. Specially with boost over 20lbs. Is it worth getting the billet drum and etc? I'm only looking to take this car into mid 11's maybe low 11's on a good night. Mainly a street car with a few visits a year to the track. Local trams guy who has built a few local guys 200's doesn't think I need the billet parts. Opinions? Thanks
