I have searched various forums for my answers but like anything on the internet Im met with very different answers. I'm planning on building a low cost reliable turbo 2.8 vr6 . I want to no what hp limit items such as Sachs clutch, injectors , stock compression , rod and head bolts can take . I want a reliable engine BUT I don't want to break the bank . The project it is for many of you will cringe . It's a Caddy van that's on air and on the floor so I'm not off to the ring any time soon . Cheers
