Alright, so I did some searching and couldn't come up with MUCH about these, Just a thread or two with a couple responses. I know The Shodan said he had used them with good results but I'm just curious if more people have ran these. If I was going to get one from them I would have to decide between the one with with the 550hp cabability, or the one with 875hp capability.

Can I get some input on what some of the turbo gurus would run if they were in my situation. I'm looking to make maybe a little more than 550 horsepower, or right around 600. Would it be more beneficial to get that core thats a little bit smaller, or the larger one with a little pressure drop? Thanks!
