Hey guys. I have heard Ferrea Ti retainers are only good for about 20k miles. What about the springs ? Do they need replaced with the retainers ?

 

Thats pretty much a load of crap.. modern parts are good to do pretty much what you want with them. I have cars with 30-40k+ on springs come through on a regular basis with no issues.

 

How fast are you spinning it?

 

9k only. I just went Ferrea Ti for the upgrade. I may go 9500 with my build bottom end didn't know what I should do. I was gonna buy new retainers and just run the same sprigs.

 

I sure hope TI retainers last more than 20k. I just put some in.

 

I was always told by my engine builder that titanitum is not a good metal to use for retainers. The wear characteristics do not suit it well. You should use steel instead.

Springs are good for a long time. The low mileage suggestion is most likely for the ti retainers only.

 

I have also heard the same thing about titanium retainer.

 

Same here that's why I stuck with ap2 retainers when I upgraded my ap1s.

 

I've heard those stories too, but does anyone have any actual Experience with TI retainers? I did a little bit of research, and it seems that TI retainers last a long time as well, except in Race applications where they drive their car hard for long periods of time. But then they just replace them again with TI retainers after they wear out.

 

I reported on mine a few years back. They were starting to gall at 20,000 miles. They were no name ti retainers at the time. I'm currently running Skunk 2 Ti retainers and will be checking them in the next couple of months.
