I want to boost a b18b. I only want to run about 6-10psi. I am not sure what turbo i should get. I want something that spools fast but keeps boost in the high rpm range. I will take any suggestions. Also if you have had a bad experience with one turbo please tell me about it so that it doesn't happen to me. And one more thing, is a block guard worth the money, where can i get one, and is it hard to install. Thanks for all the help.
