Pictures of Housings and Irons

I pulled these out of an engine that had 80k on it and had sat for almost 10 years here in the US. This is only my 4th engine dismantling and my first FD engine so I'm looking for opinions on the quality of the parts.

I understand I still need to spec the tolerances, etc. and it always isn't easy to offer an opinion without physically being able to see the parts. That being said, experienced opinions are nice.

For what it is worth, both of the rotors had all seals in place and all came out with minimal effort. One apex seal had a very, very tiny chip missing from it. As there is not apparent damage to the housings or the rotors (to my noob eye) and the car did not come with the turbos I am guessing that this missing piece of Apex Seal went for a visit to the stock twins!

There is no flaking on the housings and no wear marks that I can visual pick up on the irons or feel with a finger nail.

Anyhow...on with the pictures!

They look good to use from my point of view. Of course it would be easier to see if they were cleaned. Be sure to measure them per the FSM.

By the looks of things I would bet the rotors had quite a bit of carbon build up on them.

Good luck and keep us posted.

Good call on the rotors...this engine certainly had no AI! I'll post before and after shots of the rotors as they are caked in carbon!

Best way I have found to get the rotors clean is to soak the rotors for 6 to 8 hours in purple power and then rinse w/ water, the carbon will melt off the rotors. Good chance they will be carbon free when pulling them out of the solution. This should keep you from having to do any hard work on them. Works great for me and I have had no problems w/ the purple power affecting the bearings.
