rx7vadim, I have 36,000+ miles on my original RA seals from 3 years ago and I have the same compression now as I did after the seals were first broken in and beating on them pretty hard.

Did you use stock springs or RA?

You can re-arch the stock springs without any problems. That's what I did.

Oh, I definitely used the Mazda apex seal springs. I bought a new set of springs from Mazdatrix a few years back for my rebuild. My RA springs are sitting in a bucket somewhere in my garage with a bunch of other junk stuff

yup, I've got RA seals in my 6 port high compression turbo motor. I'd say the motors aproaching 8k right now and the last time we check the motor was around 115 on all faces. Mazda springs BTW.

Yea. But did you warm up the engine to operating temp.?

Water? Just bend them with your hands back to with-in factory specs. Your not working with some thick metals so heating isn't necessary.
