Those rotors look like they'd be great candidates for some 3mm seals, but that's just looking at them through the pics, it's hard to tell without the apex seals/feeler gauges in hand. Sounds kinda like the old engine suffered the same type of fate that the current engine suffered.... sucks

Glenn did tweak a Renni shaft. It is the only one that I know of as well. There are rumors that Mazda didn't use the same tempering as they did in the REW shaft which is why it bends and stays bent. Which is what happened to Glenn. The REW shaft is tempered so when it does flex slightly, it returns to it's original position more so than the Renni shaft will. I know there are a bunch of higher hp guys running them, I can't tell you if it's been cryo treated though. I'm running one, but mine along with the rest of my engine is cryo-treated. Don't know if this is what's making the difference. It's all kinda hear say though, I've never seen someone say definitely whether or not its weaker or not. My buddy has a 1986 M1009 CUCV with the 6.2L diesel. He had the thing for maybe a thousand miles before accelerating up a hill and snapping the crankshaft. Bought a boneyard pull out and just got the thing running last night. Looking at the break, it kinda looks like a shitty casting.... have you ever seen one of those 6.2L's snap a crank like that?

Johnathan - I'm all up for some experimenting with reasonably priced seals in a boosted engine. How much experience do you have long term with the ALS seals? Like tearing down a 50k engine and not seeing any chatter marks? How do they compare in weight to the OEM or the RA seals?
