Cryo-treating engine parts questions

[Red Lightning]

I've heard about cryo freezing engine parts to make them stronger. There's a site that claims up to 150% stronger than before the cryo treatment. Is that realistic? What is a realistic increase in strength after cryo? I'm not sure if this belongs here. But I think this forum has the highest chance of people have experience with it. Thanks in advance.

I've heard it's a total waste unless you plan on doing some serious endurance/track racing. It adds to the longevity of the motor, but i wouldn't throw away my money to it. If you're going to spend money on something like this, look into ceramic coatings (pistons, downpipe, turbo, etc).

it works, but imo, it isn't necessary.

Works great if needed. Its been proven to extend the life of high stress parts tenfold. If I were doing anything pro, I'd have the entire motor, manifold and turbo cryo'd. It totally stress relieves the metal.

For a daily driver I'd suggest coatings first.

Would be awesome for KA transmissions. Can't cot anything in there. LoL.

It's $450 to cryo the entire motor, so it's not too expensive.

Think of it this way...

You’re going to spend 10k on a engine build + Turbo...

How is 1-2k more going to hurt you? For 50% more life + be able to have higher HP... I think its a very smart thing to do.

I already got my Mani and Turbo Cryo Treated.

Also Cryo helps with making heat displacement even on the parts... So I'm going to send in my intercooler and all engine parts.

I would get stuff ceramic coated as well...

If you’re going to do something do it right.

I'm probably going to cryo my 4G63 if it need a rebuild. Does cryo treating the mani and the turbo help? It seems like there won't be much wear on the mani, but there may be some benefit to cryo treating the turbo. Thanks for the replies.

The manifold and turbo get super heated and cooled on a regular basis, which expands and contracts the metal constamtly...which in turn streeses the metal somthing fierce.
