So you´re selling the engine now that you´ve reached your goal,do I understand that correctly? Although building a Challenge motor is a ton of fun,I think you would regret selling the T4 because it does do everything! It´s reliable and incredibly fast.Besides,if Thorsten actually does make a type 4 version of his heads,which he will it seems,I think you could unlock even more horsepower.....just to scare yourself
