Ported? I assume it has ports

No, as far as I know, it's just a old stock motor.

Someone on rx7club.com suggested the apex seal could be popped back on the spring or something...basically saying there's a slim chance that it's still salvageable.

I'm going at 1pm to get the Tempo looked at, hopefully we can drive it until I get the MX-6 back together (should be a few days) and then make the decisions on the RX-7.

I've yet to tinker with the exhaust end of it...I'd like to look inside to see the seals for myself, perhaps after getting the other car on the road, I'll have more time to do that.
