Just to make sure I am reading that correctly, the head is 127.5mm thick and the service limit of 0.3mm. if my head is thinner than 127.2mm its shot?

That's a correct interpretation.

Time to get back after it. Due to the service I received here in town, machine work is being done in Colorado which unfortunately has added to time and cost.
I went to see a Murder by Death/ Devil Makes Three concert in Denver this weekend and I picked up my crankshaft on my way through. Since the shop strictly does crankshaft work, I have high hopes. I also picked up a new(er) Mini from a Subaru dealer (blashemy?).

When I pulled the block apart this winter, one rod journal was a thousandth out of round so I had it cleaned up and nitrided.

So tonight I spent my time measuring journal sizes so I can sort out bearings this week.

Main journals front to back
2.3519
2.3516
2.3518
2.3515
2.3518

Rod Journals front to back
2.0263
2.0263
2.0264
2.0264

Hmm I just found the factory service manual and both journals appear to be ground outside the useable limit.

Fantastic.

Subaru oversize doesn't seem to be thick enough. I'll have to call around tomorrow.

I called King and they don't go far enough undersized. King and oem down, on to ACL now I guess.

Of anything I have done to this car, bearing clearances are probably the thing that I'm the most nervous on and can find the least firm direction on. And it's worse now that the crank has been ground, especially since I think it's been ground too far. I'd definitely appreciate any input that's out there.

Just an FYI, the stock non-turbo 2.2 has the same crank so you could pick up a good used non-turbo 2.2 crank and use that. That would eliminate the bearing concerns. I know it'd be some more polishing and any other crank work you want done to it, but would eliminate the bearing oversizing.

Thanks.
I spent the week calling bearing suppliers. The guy at King had something going on in the back ground and wasn't really talking to me and finally said I don't think we have anything. I called ACL after and the tech guy just hung up on me.

I took the crank to the only good machinist in town (he's just a little slow, took a year to bore my block at the start of this fiasco years ago). He called me back Friday and said he had some bearings on the way that should be in the ball park and at least a good start toward correct clearances.
