assume everything is fine, mazda seals will hold higher compression.

BULLSHIT. The seals I run survived a 16.9:1 @ 15psi detonation event... basically cruising @ high rpms, high vacuum and punched it. Boost when from 15" to 15 lbs in a split second and the car detonated so hard it nearly knocked teeth out. Pulled over, pulled a datalog, found the problem, fixed the problem, drove another 1000 miles before doing a compression test.... which showed 114all around

you were lucky thats all.
a warp seal might kill whatever you said as well, Mazda choose to heat treated their Apex tips for a reason.

Not to mention... I would much rather have a seal warp and loose compression than break and wipe out a rotor, a housing, possibly a plate and possibly a turbo.... so no, the results are not the same

each to their own, see above.

Things go wrong, and they go wrong faster than you can react. I wouldn't use mazda seals for a hi-hp engine even though plenty of people do.

I agreed, but
again, each to their own. there are people who use it and they're ok with it. so can't really say who is right/wrong, just a preference.
I run Ceramics in mine. choose because it's easy on housing, and they last almost forever. sure they're harder and if they break, 99% will kill everything, but I am willing to take that risk.

I wouldn't add the shims. I did in mine and ended up taking them out and my oil pressure is still 135-140 at cold start, and 100psi cruising down the highway. It's just too much.

The front is really just there to prevent the oil system self-destruct, most of the time it will be bypass at the rear.

Just make sure that it's all lined up when you test fit the gear/bearing assembly. I use a little grey permatex or "right Stuff" in the corner and that's all you really need.

I fit it without any issue, you can tell if by eye. and I just put some silicone and it works fine. Some people even use Hylomar, and they're fine. in the other words, use whatever works.
