bigsteveturbo

Im going to a single turbo setup and and was wondering what would be the ideal turbocharger to go with im shooting for 400hp i have an opertunity to buy a garrett 30r turbo for a good price but im getting feedback from some friends that i should go with the gt35r turbo instead. also what manifold would be ideal i see on ebay thay have alot of choices but i dont want to buy any crappy manifolds that crack. im open to any ideas and information anyone wants to share.....
