It's a JDM Trust Greddy TDO-25M Turbo w/ a 50 trim I believe.
I think that turbo would be way to small for an LS motor, it says it was being used on a little Cappuccino which has a pretty small motor.
Check out rockymtnturbo on ebay as well.

But yea, about the piping and such, talk to Charles. He can probably do log manifolds as well but here are a few other places i would look for a nice manifold. I've heard good things about all of them.
