Okay where to start: May car has done 130,000 miles and it has an APR remap. And the following has just happened in the sace of 3 weeks!! My turbo has gone and it whines like a super charger!! Gear box has gone(syncro in 1st gear , but will get that reconditioned) And my head gasket has gone. Also 1 spark plug is threaded in the head and can not get it out. So what i need to know is, if i want my car to be running at about 300bhp What parts would i need and where get get them from?
