Are you racing or bashing? How much $ do you want to spend? The lrp spec 3 is a great mill or a Picco P3 .28 they are both around $200. Now those you can bash and or race with and do just fine. But if you wanted to spend like $350-$400 you could get a much better mill but I would say just get 1 of the 2 I mentioned and you will have more than enough power with a good exaust.
