Just got done making the driver side exhaust manifold and ran out of pipes. New pipes coming tuesday so the passenger side will be done then. It's a tight fit but it'll work

 

Very clean looking install.

Keep up the good work.

Where did you get the materials to make your headers?

 

the headers were made from regular mandrel bent aluminized 1.75" piping. I got these from summit racing for like $12 each. Took me 5 to do that driver side.

 

Well, definately cheaper than buying a set of headers, but alot more work. Just to make sure I looked up the right pipe, is this it?

HED-12012 90 Degree Mandrel Bend, 1 3/4" O.D. 3" Radius, 3 1/2" & 16" legs, Each $14.39

Also, what did you use to make the header flanges to bolt them to the heads?

 

... that's the RX-7 that I have always wanted! lol
I'm guessing you don't get too many kind words from the RX comunity... they usually hate domestic engines transplants.

Good luck!

p.s. very clean install

 

You can say that again.

Looks great John!

 

Ohh, I remember all the great threads on the RX7 boards about Jim's car/motor. You would've thought he bad mouthed Dr. Wankel himself.

If you don't mind asking, what are you doing about transmission/rear end? The LS1 idea is a great one and I'll guarantee that you'll see a lot more of them in '04. I never even dreamed of putting a turbo on a LS1RX7 though. I was always thinking a nice "little" dry shot under the manifold would suffice.
