Do you know what caused the plate to crack? Would suck to put the engine back together without correcting the cause of the problem...and then crack another one.

They look good, How many thou.001 max do you grind down on the housing?

What type of CNC/grinder do you guys you use to keep it very consistent...?

Thanks

I have no info. on this. Just from personal experience they found a way to provide a better rotor housing to work with..

over boost from hose popping off for wastegate.
these housings looked grooved up, might have to send them out. they arent deep enough to get caught by your fingernails but u can feel it when passing fingers over the surface.

Alex, there is a variety of apex seals on the market. do your homework and then purchase some. No more tips for free..

and yes that housing will end up flawless with Goopy's refinishing job.

I really like the look of this, and I think that it's great to finally have an option to machine your housings, my only question is:

Why did this take 20 years, and how come no one figured it out before? Was it lack of precision technology, or what?

^I was thinking the same thing. There certainly was a need for this service!

very impressive work ... and for a price that a loser like me can afford.

i doubt if there is any one reason for why it's taken so long. maybe it's technology. maybe it's changes in attitudes. hell, maybe it hasn't been 20 years - i mean, if Ito got a set to test 3 years ago, then there had to be a period of time where this went from an idea to a part-to-be-tested. either way, it's a long-awaited, welcome option for many of us, and hopefully a stepping stone to even better innovations for this engine that we love so much.

I would say things like this are starting to appear because
-Mazda prices are insane
-they are probable stopping production or already have and there is limited stock.

What needs to be done is recoating/refinishing. All my engines (I have at least 12 housings last time I counted. I thought I had 6 until I move a few boxes. Man 20 years makes stock piling!) have the dreaded corner seal triangle wear or have apex damage. Makes them useless with todays current offerings.

I'm going to drive down to Goopy Performance after my DGRR trip
