Modified BBS turbo manifold for S475
I'm running a BW S475 Turbo on a BBS manifold. As most of you know the BBS manifold uses a 38mm WG. Well that WG is WAY to small the S475. So I got a JGS 50R WG with uses a 2" tube. So I had to modify my manifold. Here is a picture before getting it ceramic coated.

Looks great. Are you going to add some sort of support bracket? S400's are HEAVY!

He modified the wastegate tube for a larger wastegate to control boost on a single turbo application, its in his first post
But you bring up a good point. Looks like a T4 flange as you can get the S400 on a T4 flange. A t6 is massive and that single tube that the BBS is design around is not big enough to fill the T6 opening

Re: Modified BBS turbo manifold for S475
I'm curious what kind of pulley system you are running for the belt-driven accessories?

Re: Modified BBS turbo manifold for S475
That is correct ... The alternator and bracket are a Powermaster, which I got from summit. S10 manual steering box.

Re: Modified BBS turbo manifold for S475
Looks good. I blocked the stock wastegate tube like you did and put the wastegate under the car on the cross over pipe on my setup. I might end up moving it back up on the turbo header tho. So i can route it right back into the downpipe.
