Twin Turbo Project - - - looking for manifolds!!

[Brett 91 RS LT1]

I'm at the very beginning planning stages for my next phase of evolution for the RS. I have decided to make her a twin turbo system. I have a few ideas and a few other peoples' cars to base my plans off of.

I would prefer to avoid having to shell out for a local shop to custom-weld me a set of header manifolds. Does anyone know off-hand of a shop or company that has chevy V8 turbo manifolds?

In a perfect world I would be looking for tubular manifolds that would mount the spools in roughly the same position as the old Gale Banks twin turbo kits for 3rd Gen F-bodies.

I'm also looking for any sites with literature to compare and qualify different parts.

Right now the 355 is maxing out my 24# injectors at only 4300rpm. 100% duty cycle! This on an engine designed to see max rpm over 6800. It is built for boost. Down the road I may step up to something larger, but for right now I am looking to build a turbo system that can be dialed up to 10-12psi.

Will a pair of 60-1 Hi Fi driers be enough? I don't know. And I need to educate myself on exactly "what is what" on the market today. I used to be up on it when I had my 86 T-type (white), but the car was hit and I sold it before I graduated high school - I never had the chance to mod it beyond a chip and a cheap muffler.

I'd appreciate any help in the form of links, pics, or info! I hope to have parts purchased and waiting for the Fall to do the install.

Whoever said "If it ain't broke, don't fix it" just didn't get it.

Brett you may want to contact Conley's in
Houston (281) 540-3278 they have a vendor that does turbo headers for chev v8's.

I would talk to Lawrence (after 0500pm Houston time) he now runs a twin turbo
camaro himself so should be able to give you some ideas.

Good Luck
