I have personally used them with new apex seals on every build. sometimes used apex seals have a step on them. so If you do use, used apex seals that spec. out good enough for a rebuild. a longer break in process will have to take place.

motor has about 10k miles on atkins seals. the front iron cracked on dowel land so i gotta tear it down and replace the plate. btw ITO its alex.
motor still sounds like it has compression

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

u cracked a plate? you have other issues to worry about Alex..

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

ya the front plate cracked sux. but wat can i do :icon_no2:

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.

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.

send them out. and use new apex seals.

which seals should i go with ito? and should i replace oil control o rings as well?

here is the housing

Alex, there is a variety of apex seals on the market. do your homework and then purchase some. No more tips for free..:cheers2:

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!

hmm i might lookinto this more when i get home
