Has anyone ever heard of this place? If so are they any good?

They do a lot of work building engines for SCCA race cars. They're good from what I've heard, but don't expect them to be cheap. ;)

Including World Challenge car's. At the DC race Roger Foo had a motor in his rig with Sunbelt on the crate:)

They know the SR20, but aren't cheap and it is rare occaision that they will work on an individuals car (i.e., non-race teams).
