Single Turbo

Hey guys what would you recommend on size for a single turbo for a 351 cleveland. Would want 650 hp. Would be using 4v cast manifold turned round and a set of alloy 4v afd heads. It has to be a ball bearing one. Any help would be appreciated.

Re: Single Turbo

$1990 trade from GCG for GT42 plain bearing $3700 for ball bearing, you wont need ball bearing with a 351 I am probably getting this turbo from the US and it should support about 850hp on my 351, they are most efficient upwards of 20psi when used on a 351, ball bearing is only really needed when running the same size turbo on a smaller motor or when boost is going to be more than 25psi. But if you have the money I guess BB is better option. There are many other turbo's ather than GT ones that are often cheaper and lighter as well, The GT42 is a heavy bitch but everyone who I have read about that has used one has no problems with it.
