The check valve closest to the crossover pipe is the pressure chamber check valve. The other is the vacuum chamber check valve. A cracked pressure chamber check valve will hinder primary boost production. A cracked vacuum chamber check valve will affect how the secondary turbo comes online. I'd replace them ASAP, unless you want to be frustrated with boost control problems...

Do you have the product number of a circle-seal check valve that would be a plug-and-play unit? The catalogs are not very detailed.

don't race, don't need to
Call Ray at Malloy. He knows the check valves, and will get you the right ones.
Also, be aware there is a "vacuum hose replacement kit" available from mazda. The kit runs in the $175 range, but includes ALL the check valves and many hoses, most of which you won't use. As compared to the individual cost of sinle check valves at a a time, it's a MUCH better way to go, IMO!

That being said, I agree with Mahjik, get the OEM ones, they're durable enough, especially if you have cooling mods, then they'll last even longer.

Talk to Ray Crowe
If Ray isn't around, the other guys seem to be equally qualified or just leave Ray a voice mail. He will get back to you.
As far as actually replacing them? Just make sure you check the vacuum diagram and have the check valve arrows going in the right direction when installing them. That's it!
You may as well check all the other check valves that are in reach while you are there. Just make sure you can only blow through ONE direction.

The quote below comes form this link: http://www.autosportracetech.com/RX-7/faqs.htm
What are the part numbers for those one-way / check-valves?
The all White one: N3A1-13-1995 (note: this is a revised p/n and is a very expensive part - $40)
The Black/Green one: N390-13-995A
The Green/White one: HE41-13-995
The Aluminum one: NF01-13-890
Note that Mazda has been consolidating part numbers lately and has started using N390-13-995A for the Black/Green and White/Green.

I just bought a used one for $1...plus the shipping, which turned out to be more than the actual check valve. $30 is beyond ridiculous though...
