I'm trying to get a group buy going to have titanium retainers TiN coated. I need at least one other person to place the order because of the minimum order at Brycoat. The cost will be $65/set +shipping. Normally, if you send one set to Brycoat, it will cost you $100 +shipping. This is only for the coating, but I'm willing to find you retainers for a good price as well if you like.

I've done quite a bit of research on all of the different retainer materials, and have found that the most robust option is TiN coated titanium retainers (as long as you buy retainers with a thicker flange than stock, like Portflow's). These retainers will be stronger and lighter, and because of the TiN coating, will be harder and more lubricious. This will stop the notorious galling problem with titanium retainers, and I have never seen or heard of them cracking.

Thanks,

David

 

I know someone, let me link him here. I have brycoat on my retainers... it surface hardens, does nothing for the internal metal, still it is a good idea

This is Duy from OC, you're Dan's brother right?

I have a set of retainers that need to be coated.

Thanks Schu for the heads up.

 

Oh man... This is dan's bro??? Let's get some drinking going on baby! can you have dan e-mail me please?

Hi Duy,

Yeah, this is Dan's bro. I think we met in OC. If you've got some retainers, send them to me at:

David Platt
1285 SE Smock Street
Sherwood, OR 97140

I figure I'll leave the post up for another few days to give more people a chance, but then I'll send them straight to Brycoat and back to you. I'll ask for Paypal payment when I'm ready to send them @ dntplatt@msn.com.

Thanks,

David

 

Yup, Dan's bro, Dave here. I told him to shoot you an email and gave him your adddress. His is g2guru.hotmail.com.

Agreed, TiN is surface treatment only. The coating brings the surface to a hardness of RC 90, which is 30% harder than tool steel, and it also gives the surface a much lower coefficient of friction. I stated that the titanium retainers were stronger than stock becuase most companies make the outer flange thicker than stock (nothing to do with the coating). They can pull this off becuase titanium is 40% lighter than stainless.

Thanks for the referral,

David

 

Why not cryo treat them?

 

You have to choose between Cryo treating them and TiN coating them because you cannot do both. The reason is that the TiN coating is done with a high temp PVD process which would reverse the Cryo treatment. If you coat them first, the Cryo treatment can destroy the integrity of the TiN coating. I have talked to both NW Cryogenics and Brycoat about this when I was trying to build a bulletproof transmission.

Though the Cryo treatment makes the material stronger with a harder, smoother surface, it doesn't give anywhere near the hardness or lubricity of the TiN coating. If you buy good titanium retainers (I recommend Portflow), the material is strong enough as-is since the flange is made thicker. The TiN coating is only necessary to prevent wear/galling. Cryo treatment is cheaper though.

OK, I'll get them out this week.

 

What are you building now dave? you guys coming to cali anytime soon?

 

Since I blew my D16, I'm building a B18C-R to put in my Civic. It will have all of the bolt on's, Toda B cams, and Toda valve train. It should be pretty quick! Definitely will pull better than the 14.5s that I got with my SOHC.

Probably make a trip to Cali next summer.

Later,

David

 

Hey David,

The retainers are on their way. Please let me know when they get there.

Thanks,

Duy
