Wow, talk about machine parts porn!
The cryo place is in my general neighborhood. Time for a field trip.
To absolute zero and beyond!!!!!
Why doesn't this surprise me Chris? Always something beyond cool going on into your builds.

The Albins ring & pinion arrived one day after being ordered and is now being shipped out for cryo and REM Superfinish treatment. OOOOOOH! Shiny.... Obviously not a ring & pinion but this is the result of the work.
There are proven benefits to this and if you really want to geek out, here's a link to the place that's doing the work. There are a bunch of papers on all sorts of interesting stuff related to these processes.
My primary reasons for doing it are that it all but eliminates the run-in period and associated risks and is proven to measurably reduce parasitic losses in the trans, improving both RWP and coast down numbers.
Worth it? Overkill? Stupid? I'll let you know!
https://www.cryogenicsuperfinish.com/processes/
The trans is then headed to CMS in AZ where this ring & pinion and an LSD will be installed. The trans will also receive a general going over and whatever needs refreshing will get it.
That's the sexiest crank I've ever seen...spin that sucka to the moon!
OK, this may qualify as the "absolute least action" picture. Why? Because that there is my new ring & pinon in the cryo chamber!
See what I did there? Really, cold, like downwards of -300, so not a lot of moving = not much action... OK, sorry.
Anyway, here are some general geek-out benefits to the cryo process:
-Increased abrasion and wear resistance
-Increased fatigue life
-Increased ductility
-Reduced residual stresses
-Mild increase in tensile strength
-A change in vibration characteristics
Specifically for gears:
-50% extra pitting resistance
-5% more load carrying capacity
-40 to 60 degrees higher tempering temperature
-treated gears operate cooler in friction action
-3-4 times increased life of racing gears, including drag racing applications

That is so cool!
Learn something new every day; that is certainly a very cool finish. 
Step 1: Modify stuff
Step 2: Drive a couple hundred miles
Step 3: Take it apart to do something else
Step 4: Repeat!
Here we go again. Trans is out and on it's way to get the new ring & pinion and LSD installed. I'll pull the engine tomorrow and go to work on finalizing everything in the engine compartment area. I have a little bit more metal work and wiring to do.
Once that's done, I'm going to spray heat/sound control on the back of the fire wall then paint this area.
The goal is that everything under the trunk and engine lid will be done for WCR.
Wish me luck!

70 mph it's spinning about 3000 RPM. Way too busy when I'm on the freeway.
Good thing you never had a 1st Gen Miata. Was more like 3000 RPM at 60 mph on the freeway in top gear.
As always I can't keep up with your posts -- great work on the magazine coverage and getting some real world seat time with the 914!
@tygaboy - Have you selected a color?
QUOTE(Cairo94507 @ Apr 12 2022, 08:24 AM)
@Cairo94507 - Michael - For now, the engine bay will be done in a medium gray. In the end, the body exterior will likely end up in some sort of dark-ish blue. I like Porsche Lapis Blue but in a non-metallic and with a bit less purple. Such a big decision so nothing final at this point.
I pulled the engine yesterday so now it's time to tidy up everything and get the trans ready to ship. I also have a number of items that need powder coating or plating. Things should look pretty good once it's all back together.
I can't wait to see it going back together with finished parts; it's going to look epic.
What to do when you've sacrificed both trunks in the name of water cooled HP and maximum access/style points and you want to attend some far away events?
Getting ready for some road trips!
@buddyv Robert found what I think is the best looking luggage rack and he's letting me play with it for a while.
If I can't talk him out of this one, I may have to make my own copy of this. I love how it looks like a spoiler!
Do you disagree with having a luggage rack on a hopped up 914? Have you seen @SirAndy Andy's car?

Hmm, wonder what else @buddyv has been hiding in his stash? I think it looks great. A bit bold but luckily, your car can pull that off easily! Time to drill some holes in that deck lid..
NOOOOOOOO! (Hey, you asked.)
Its either that or a track type trailer.. Make the back of that thing a spoiler???? Since you will make your own.??

Chris - well if you're considering that, then the logical extension is, surely:

Build the rack on a second roof panel, then you can simply swap out for local or touring use.....! Extra lights and front bar are optional.

Thinking you can fabricate a huge stainless suitcase to match.

that clicks or latches into tracks on your rear lid! Two strip of stainless (rubber lined) that run front to rear on top of the lid. Sleeker, purposeful and more modern like your car.
The only suitable cargo solution is a trailer made from the rear half of a 914. With flares, of course.
Or just travel with your credit card.

@Superhawk996 - I don't know what you're talking about.
OK, so yes, I am going to test fit the engine and trans. Low probability the stock intake will fit but I'll know a lot more about all this in the next day or so.
Gotta say, the trans looks straight out of a race car. If the ring & pinion area looks huge, it's because it is; part of it serves as a the dry sump tank.
Get a second trunk lid and paint it with the car so you can install when the rack isn't needed. Or, design a couple of rails that you can attach the rack to when needed. Oh wait, you don't like design projects....my bad.
There is no way this will fit in my car. Why even try?
Lube! We need lube!
Well, now. This is encouraging...
Holy McEngineSwap, it fits. I would have bet big $ this wasn't going to be the result, but here we are. The whole drive train needs to come up maybe another inch but it all looks totally workable. The axle angle looks better than with the LS/Boxster, the rear of the trans clears the body work and it looks like it'll all work with a stock fire wall location. 
Good thing, because I've sourced another 914 and this drivetrain is going in!
I'll be starting a separate build thread for that one.
My existing car will keep its LS/Boxster set up and continue to be refined.
But wowzers, this is so f-ing COOL!

Very cool.. crazy that these engines are available like that. I would think qtys would be pretty low in the resale market
I can't believe that engine/transaxle fit; that is just crazy. You're going to need a bigger barn...
Ferrari engine in a Porsche. Soon dogs and cats will sleep together. Where will this end……
All I can think is "Chris, you made a time machine outta a 914!" 
Gonna feel like a dam time machine with that pushing it!

I'll be sending you my preferred spec's for that next build . . . .
Hoping this is the last pic of this before I start the new build thread.
How cool will it be to have this peaking out from under the bumper?

Confusing.
Enough of this Ferrari silliness. Let's get back to important things. Like voiding warranties by adding style points!
I've never been a fan of large expanses of plain material. In this case, it was my engine adaptor plate that wasn't doing it for me. I was losing sleep! It was just begging for some relief pockets.
So yesterday, when a machinist buddy stopped by to borrow a bending die, I asked if he could help. About an hour later, he sends me the pic.
Another touch that will likely go unnoticed by nearly everyone. Fellow style point appreciators @buddyv Robert and @Mikey63 Mike aside!

@tygaboy - It is your attention to detail that sets this car apart from other builds. So, yeah, I love the reliefs cut into the engine adaptor plate. It makes it visually interesting.
I so look forward to seeing it with some plated parts and paint all assembled.

Chris, I’m really liking the vibe of your new build! Can’t wait to see it in person.
For those who've never seen the flywheel that's part of the LS/Boxster adaptor. It's a beauty! A big and heavy beauty, despite the lightening effort. But it has a big responsibility, don't it?
And my machinist buddy called and let me know to come pick up the part! Less than 24 hour turn-around. See, it really is all about who you know. And in this case? I know JP Morgan. No, really. That's his name. It is.
Sharp eyes will notice I'm form over function on this: the pockets were cut only in those surfaces visible from the top. Yep, it's all about style points!
Now if only I could do something about the back sides of those cylinder heads...

Public Service Announcement and Cuteness Overload:
My build may be slowed down a bit! My wife volunteers at Morti's Used Book Nook and Cat Adoption Lounge, here in Petaluma. Yes, it's a book store with free roaming, up-for-adoption kitties. It's a remarkable place.
https://www.petalumapetpals.org/mortibooksandcats
Anyway, we're fostering mother ChaCha and her litter of four. Once they reach 2 lbs, everyone heads off for spay/neuter then on to Morti's before heading to their "furever" home. Here I am, falling hard for Hula, while her brother, Twist, ignores us.
Second pic is the whole "Dance Crew". From left:
Twist, Disco, Hula, with JitterBug there in the background.
It's so easy to spend hours with them.
The PSA part of this is: If you can help foster, please consider it. These animal rescues do such amazing work and they need all the help they can get. Thanks!
