MY OPINION ON YOUR TURBO...... YOU SAID YOU ARE A BEGINNER AND NO EXPERT... I THINK YOU SHOULD STICK WITH THE BASICS AND WORK YOUR WAY UP TO A TURBO, OR HAVE SOME TURBO PRO GUY BUILD THE ENGINE AND SET UP THE CAR FOR YOU.... I DONT KNOW WHAT KIND OF CHASSIS YOU HAVE OR DRIVETRAIN SETUP BUT ALOT OF BEGINNERS THINK IT JUST TAKES AN ENGINE TO GO FAST.. BEST OF LUCK IN 09 RACE SEASON....

bbc is the way to go i hope by now u have it cause that opportunity doesnt come often, also most 454 can go more than a thirty thou overbore
