just wondering what kind of expansion tank for the FD is avaible rite now cause my oem expansion tank is leaking and i need a new one....

 

I was going to go with one from Pegasus:

Page 65, part number 2584.
At $80, it beats the $170->$200 everybody wants for an "RX7 AST". I also think the shape & size works better.

Alas; was, as we went ahead and did an 'ASTectomy' instead. [search on AST removal]

Good luck!

I always thought that the whole rx-7 specific ast thing was silly. It is just one specific application of an air expansion tank.

If you take a look in either Summit or Jegs, there seem to be many viablie alternatives. I was going to go that route, but I found an aluminum AST for really cheap and bought it instead.

Food for thought....
