Looks like the Cosmo water pump I cut down for you Bulent.
Lookat the SIZE of those Cosmo two rotor intake ports. Wow! Cool!
Another example of why we need plenty of meat on that intake manifold Tom.

What you see is my spare 1993 engine that I sold to John. The pump is a

Thanks for straightening me out. I have a lot of trouble telling the
difference
between a Cosmo two rotor and a 93 and up RX7engine.
I think John's motor mount is going to do a much better job of isolating
vibration from the engine than putting the rubber bushings in
the anti oil foam plate next to the engine. Why are you doing that?
Why not just copy John's mount? The rubber bushings will also be in a much
more benign temp and oil environment if mounted in the firewall.
Here is the old original drawing of the idea.

If you think so, I just may do it. I was also concerned with the heat factor
on the rubber mounts. What is the effect of the engine vibrations on all the
welded joints?
Hate making these flanges all over again. It took lots of work on the lathe.

Chuck Dunlap made his own silicone rubber bushing by gluing together
1/8 thick donuts with red RTV. The best stuff to use is from McMaster Carr.
The silicone sheet is reinforced by fiberglas mesh. The stuff you get from ACS is
sans fiberglass mesh. I think you can also buy silicone bushings from Barry at
great expense.
I have some punched 2" OD 1/2 inch hole 4130 washers and short sections of
tubing I can send you. You can then have them tig welded up. I had a whole
bunch punched out of .109 or there a bouts. You will need eight with four
pieces of tubing unless you buy some snubbing washers from Barry.
Just send me twenty bucks cash or check for the Everett Hatch Memorial Race fund.
BTW the gif explains why you need the tubing reinforcements near the firewall.
