Re: JS LSX Turbo complete kits...anyone heard of this?
I've seen the s475 a bunch of times on LS's. Realistically you won't see "max" boost on either turbo with that small of a motor, but that doesn't mean they don't work.
the 475 would be making over 450 at ~12-15psi, with a sh!t ton of room to grow. Seen them pushed 20ish psi making near 600. The s400's are physically large tho, just keep it in mind when deciding where to put it.
