[quote name='ColinRX7' date='Jun 14 2005, 11:38 AM']Can't you epoxy the passage with it assembled?
I was JUST at my garage inspecting 6 port irons for cracked water seal grooves (from something I was reading about earlier), and I completely forgot to check out the EGR path for you..

Too hot I'm pretty sure.

[quote name='DUB' date='Jun 14 2005, 11:38 AM']DAYEM!! very nice. 11,000 rpms? are PP blocks streetable (driving sense not emission)
[/quote]
We'll see!
As for the RPM, I certainly hope not. The ignition I have says only to 10500RPM, and those intake runners are pretty long. Since I didn't do any work on the rotors I doubt it would work too long above 10000RPM. This is strictly an expirement, done for pretty low budget.

Alright I'm an idiot, I have a rotor housing and iron assembly sitting next to me on my shelf, see my profile picture?
Adur.
Anyways, The triagular port under exhaust port of the rotor housing airs into those EGR paths in the housing, and doesn't go nowheres else.
BUT
depending on how the rotor housing is setup, the exhaust comes from through the two small holes under the port on the outside of the block, or from whereever the housing has the drilled hole through the sleeve that goes into the section there.
So theoretically you should be able to have your header flange made up that blocks the outside block holes, then all you have to worry about is which irons have exhaust coming from inside the sleeve into that EGR path.
Even then It might not be any concern anyways, because your exhaust header butts right into the rotor housing anyways, remember? That's what you showed me?
You might not have to do anything at ALL, if the header is right...

You'll probably only have one or two to worry about if at all
Look inside the exhaust port, and note which side of the port has a drilled section in the sleeve, and the corresponding iron next to it will have the exhaust travelling out below the port.
Virtually the hole points at which iron it will spit exhaust out of below the port

That's a better plan.

[quote name='TYSON' date='Jun 11 2005, 10:25 AM']I finished the mockup of my header and got the flange, now I just need to form the start of the runners a bit and get it welded!

Sweet...looks good...But where does the turbo go?
