How many V8 Camaro's and Firebirds from the mid 80's do you see still running around on their original motors?
The only real reason the rotaries have such a bad rep is most of the original purchasers had no clue as how to maintain and treat these motors. I do however put the blame for that squarely on Mazda for not educating their buyers. It's happening all over again unfortunately with the RX-8, all the people i know who had rotaries before have zero issues with them. The few people I know who never had one befor and bought the 8 based on how it looked and just babied it (or got automatics) have problems.
Also most of the second gen RX-7 buyers are broke-ass teenagers getting there first car, as with any 20 year old sports car everything is just about on the verge of breaking.
Show me a 20+ year old LSX motor.

Now I also don't wanna give impression that i'm disparaging the LSX motors. GM did an amazing job designing a lightweight aluminum block motor from the ground up. it has also proven to be one of the most reliable motor series that GM has ever come up with and I have a friend that has put one in an FC and an FD, and i have zero issue with that.
Now the one rotary motor that I would say that got destroyed the most and propogated the reputation would have to be the the twin turbo version they had in the 3rd gen Rx-7, this was due to alot of contributing factors: owner ignorance being primary, and in my opinion alot of bad design decisions - which most FD owners are now familiar with and usually fix right off the bat when buying one. Mazda again has itself to blame for not educating it's american buyers. Turbos shorten the life of any motor, put a set of twins on an LSX and run it hard for ten years and I'm petty sure it'll be pretty much done by 100k miles.
Both motors have there positive and negative aspects.

Uh I'd go out on a limb and say that there was QUITE an upgrade in quality and design with the current LSx motors, compared to similar sized GM pushrod motors from 20 years prior. You can't really make a comparison between them is all I'm saying. And I will confidently say that a modern LSx series motor will still be running strong if well maintained 20 years from now (if we still drive gasoline powered cars by then). These motors has so far proven themselves to stay strong over 150k miles in countless street cars, race cars, and hard-driven trucks. I wouldn't necessarily say the same about other GM car components...but the motor is solid.
Rx7club is a good general RX7 site especially if you're a fan of the rotary. But if you want straight up advice and tech knowledge about the V8 swap you should check out v8rx7forum.com

Kdawg - I have had a few rotaries and a few frankenstein motors - I have two rexs now ... 10th Ann T2 and a 1985 GSL-SE with Dellorto Carbs ... The motor you have now is a 6 port. Most people don't even like to work on them, but they are and can be fun and reliable. The only reason people lose apex seals is that they don't get oil chages often enough ... or people don't get cooling issues addressed. To get power the recipe applies on 6 ports as it does for 4 port motors (turbo and ol' school 12a/13b). Ignition, exhaust, intake ... believe it or not, a carb on a 6 port with the intake kit is really aggresive ... and if you rebuild ... you can streetport your setup if you want a real big bump in power and while you are in there you can opt for 4 port irons/S6 rotors/stronger seals (atkins, RA, hurleys etc...). If you looking to tubo the motor you can swap over all the components from the T2 directly on the N/A motor without a rebuild if you have good compression. If you wanna swap for a 13b-t its a direct drop in from same gen. 3 rotor drops in with a $150 mount kit in second gens - 13b-rew drops in with $350 mount ...
