...where the redwoods meet the ocean...
I just had my ring and pinions cryo treated for increased strength and wear life when I had my lc regeared to 4.88 by unitrax in anaheim ca...also planning on cryoing my head assembly when I have the head gasket replaced, I'll probably just send all the parts through superior automotive in anaheim ca since they'll be do all the work on my head and they use cryoscience to treat their parts.

I would have loved to have cryo treated my trans and tc internals and cases but I didn't disassemble them...the trans in suppose to run approx 50 degrees cooler after treating.

anyone else have experience with this company or cryo treating in general?

here's their site...

CRYO SCIENCE
 
I'm running cryo'd rotors on my tacoma, they seem to be holding up quite well. As far as the head, I've never heard of anyone doing that. From what I understood, cryo treating was for really stressed components, like gears and axles, and even then, only on steel stuff. Your cyl head is aluminum, I would think it would crack during the cold cycle. Either way, I'd be interested in the outcome!
 
I actually cryo'd my head on my 96 4runner along with the parts for it so that it would dissapate heat better and in case of a head gasket failure it wouldn't warp...not to mention the stress releaving benefits. I've heard of doing rotors too and when I do the brakes I will do the rotors and pads for sure...toyota lc stuff is suppose to last a while but I want my stuff to last forever!
 
It might be worth a try for the valves and seats but will you run the truck enough miles? The valvetrain will last 300k miles untreated so you might be better off treating your bearings, birds and brakes first. I would save the $$ for other projects.

BTW if you do treat the head make sure you replace the soft bits after or leave them out.

yeah, I definitely think it's worth it...and I keep hearing (or reading) people who say that these things will go 300k but most, if not all, have the head gasket done before 200k so I don't think that anyone really actually goes 300k without any real pm or a complete head overhaul...I'd be a bit scared to go over 200k without replacing the hg, but that's just me.

The head is my next project so that's why it's getting done next..after that, hopfully I can just enjoy the lc for a while without any more big projects. :)
 
Good point. If it weren't for having the extra time and $$ burning a hole in my pocket, overhauling the head was more about the sheer convenience of freshening it while it was off. If time and/or money was an issue I would have had no issue continuing service. Other than the need to check the valve tip clearance my machinist asked why I was overhauling it at 210K.

I'm a firm believer cryogenically treated parts offer a significant cost benefit and bump in durability. I can see it benefiting the entire valve train including the cams. Keep everyone posted on the details.

235k, original head gasket (RT knocks on wood) putting 140 miles a day on it right now, changing the head gasket on a preventative basis has been on the to do list for a few years now, have never have had the time.

not trying to be a dick but where did you find this information...
 
Sounds like a waste of money to me, but we like to waste our money here, so whatever floats your boat! :cheers:
 
You've found a great resource for improving the performance of your vehicle. I have cryo treated a lot parts on my 80, mainly drivetrain, but engine and electrical items as well. In fact, last summer I dyno'd my rig with new OEM ignition parts. I did 5 passes, shut it down and swapped cryo treated plugs (90919-01176). Immediately there was a 9HP increase (on a AWD dyno). Also the emissions went down over 1 whole point. This has equated in improved performance AND fuel mileage. I've since gone back and treated the distributor, cap, rotor, wires, coil and ignitor. I have not dyno'd since, but I can tell it has made a difference. Interestingly, the dyno operator commented how he has seen similar tests done with just about every kind of plug out there and has never seen a viable increase in HP

I have cryo treated some $100 Birfields and asked a few customers to try and destroy them. None have come back. Likewise I have installed cryo'd plugs into customer vehicles that had just replaced their plugs and asked them if they noticed a difference. All confirmed they had noticed some type of difference whether it was a smoother idle or better throttle response.

Here's a picture of a treated plug after 30K miles:

Usually you would see some type of carbon build up by now. But because the treated plugs conduct better and burn the incoming fuel mixture more completely, they stay cleaner.

If anyone's interested, I can get a batch of them treated. I usually sell them for around $10/each.
 
yep, I've heard about treating spark plugs before...gonna have everything I can treated this weekend while my engine is down and head is apart...they even pick up and deliver...CRYO SCIENCE

...so many possibilities...
 
I've spent a lot of time listening to Charles at Cryogenics International tell me about how all this stuff works. I am amazed at the knowledge the guy has. I've also learned that simply treating parts with liquid nitrogen is only half of the process. The other half is calculating how long everything needs to be "frozen" to become evenly treated. Once you understand how different materials react to the process you begin to want to treat everything!

As if this hobby wasn't already expensive:D
 
Wow .. didn't know you can treat all that stuff like plugs and what not .... I've heard of rotors like most, but hot damn !

Wish I had known that before I changed my plugs ... guess I'll add this to the list and start looking into it before I start swapping parts.

no worries...just seemed like a regular thing...

...I'd love for mine to last 300k without anymore issues but I just don't want to risk it, I'd rather fix it now rather than have it fail on the trail or leave the wife stranded somewhere...

...maybe I should have said around 200k instead of "before 200k"...

311k on mine, no rebuilds, gaskets and infrequent oil changes. :)

What kind of price does is it to treat larger items like the R&P and then small items like the plugs?
 
Interesting. I don't have any work scheduled for the cruiser, but I'm rebuilding a chainsaw right now.... :hhmm:
