got an e-mail from 300 below.

 

here is a copy of their price list.

 

I am asking them about subby heads and the cost since there are two of them, I am also asking about the short blocks to see if the steel sleeves are going to be a problem.

 

It looks like it's going to cost $3.50 a pound to cryo treat the rear stub axles. minumum order is $100.

maybe we could do a group buy or something like that and get a bunch of Stub axles frozen.

here is the email I sent them

 

Their answers are in red and bold.

*****************************

do the heads have to be bare or can the valves train be installed?

yes the heads do need to be bare. You can do the valves and valve springs separately.

How much do you charge for a set of Subaru heads? It's a 4 cylinder horizontal motor, similar to the older VW air-cooled engines

$130.00 ea . An entire 4 cyl. engine price is $450.00

For the short block, it's an aluminum block w/steel sleeved cylinders. Is that going to be a problem with the two metal types?

Yes the sleeves must be removed, but you can also do the sleeves separately.

Should I have all the machine work done on the parts before the cryo process?

All machine work should be done before the cryo treatment.

For the transmission, can I provide the entire gear set or do the gears needs to be separated.

You can leave the gear set intact.

for differentials, LSD clutch packs, wheel bearings, CV joints

how much disassembly needs to be done for these items?

All plastic or rubber parts and seals must be removed.

The less stress you have on any part the better, nothing can be torqued down, only finger tight.

awesome, thanks for doing the legwork on that.

For the short block' date=' it's an aluminum block w/steel sleeved cylinders. Is that going to be a problem with the two metal types?[/color']

Yes the sleeves must be removed, but you can also do the sleeves separately.

 

So, It sounds like cryo treating the block is not possible, since subaru sleeves cannot be removed.
