It's going to be pretyt hard to hide a turbo set up if you plan on poping the hood. Cause of the manifold. But anyway. The smaliest turbo that I would run would be a t3, should be pretty good without hardly any lag but full boost would be reached fairly quickly, which might not be something you want. HBut anyway. A good bov to run so u don't hear much would be the HKS racing bov, you can really hear anything from it but it works well.
