Just talked to Vaz...he sent me this pic.
Looks very good. He's going to send me one. Not bad of a price, either.
Can you say "new LB7 downpipe"?

Diamond Eye pipe can be had from Kat for around $200 last I called her, see if they have anymore. You can also find them elsewhere for that price. I think if you could just make a short adapter to hook a Diamond Eye onto that would be the cheapest and best route.

I was thinking more along the lines of this 
One hole in the plate center on the turbine discharge

I have my stock LB7 turbo sitting here with 60,000 stock miles on it. If one of you guys needs it for R&D let me know. I will never use it again and I don't need it sitting here taking up space. I have the down pipe with the funny flange here too. Let me know.
Well, since I'm not really a fabricator, I plan on surprising Merchant with this plate, and working with him to build a downpipe. Only trouble I see with running a DiamondEye with this setup is I dont know how we'd hook up the wastegate relief. Dont know if we could do a double V-band with those holes so close.
Best bet will probably be to just develop a new pipe.

Should only need one hole unless the wastegate flap opens past the flange or theres no room inbetween the 2 holes.
Anybody have a blown up LB7 turbo kicking around?
I like where this is goingopcorn: Would adding the plate restrict flow in any way compated to the current design?

In talking to Vasile, he was thinking that running the wastegate separately further down stream would minimize turbulence. I dont know squat about turbos, but it made sense to me. He should really explain it.
Im just hoping all these darn ideas Ive been hatching come to fruition. If they do, then 2009 could truely be a fun year. Starting to get a bunch of irons in the fire.

i have seen this done with ricers all the time, and that is where i got the idea from. i talked to a teacher at the university of northwestern ohio (where i got a diploma as a diesel tech) ; that graduated in high performance, teaches hp welding, and has welded lots of different types of headers and downpipes (like the one tom is going to do) for racing teams. he said this type of thing would work well in terms of flowing better.
I found the answer to my question, Yes the flap sticks out past the flange. Back to the drawing board.
OEM LB7. Rail runs 23,500-23,600psi after 5th gear, but its a bit lower for the first 1/8. Might need to address that.
I missed out on Michael's LBZ reg fire sale.
Vaz, this is gonna be fun. Wait til I drop the bomb on Eric. :rofl:

As I said, I have a perfect LB7 turbo sitting here. Someone here can have it for shipping if it will help. It has the fatory down pipe with it as well. I would love to see it help you guys do something. Better than having it sit here.
Well, Vaz's flange wont work in its current form. The hole for the wastegate needs to be an oval, not a circle so the gate can open. Eric thinks the flange can still be used, but he and his fab guy will need time to figure it out.
Eric gave me a stock LB7 downpipe, and I think I may take some of the guys advice and see if I can have my fab guy cut it in half and graft a larger (4"?) pipe onto the end.
If it doesnt work, I just stick with what I've got. Its worked so far.

the hole does not need to be cut like that,the wastegate doesnt open that far- the only thing that it needs is the inside of the hole (the side that is facing the wastegate) needs to be ported a 1/3 around on top on an angle clear the lever. I have done this at home to check clearance and everything is good with the wastgate actuator hooked up.
