So i have a 13B Twin Turbo motor from the 1993 RX7. I finally got a chance to take it apart and I have many Questions.
First is this Housing....
It is the front rotor housing and i was inspecting it and it look like it was damaged, or it may be like that. Can someone please help me?
And as for the Seals, I want to replace all the seals inside of it. We are very limited on Guam and i doub anyone here on island has the right seals I can order them online or through the dealership but i was wondering if the Renesis engine from the RX8 had the same kind of seals. Does anyone know? Im looking for all the rotor and housing seals and that's it. Please seomeone help me so i can get me baby running again!!

 

That is a damaged housing.

 

I would consider replacing that rear plate. Just from a visual inspection it doesn't look like it's in spec. If you send me a hi res Photo of it I can probably help you more. But there is no replacement for someone that will physically spec your engine.However if that water passage matches the others in the housing you should be ok. But I still suggest a replacement . send photos to driftergtr@gmail.com and I'll let you know what I think ASAP .

No

 

DARN! I researched a lil bit more and found someone else that had the same poblem and somebody mentioned iron welding it. I mean don't you think its salvageable? Either get it block welded or TIG Welded and cleaned up, I really don't feel like spending a lot on a housing if i can save it ya know

 

You are going to have to replace that iron. I didn't notice it before but the water jacket is cracked. You'll never get it fixed properly. You can find a replacement in the for sale section. That's going to be your cheapest option, and the fastest fix.

 

that's the front plate. and yes i would replace it. no telling what other damage might be there that u can't see.

 

that is clearly damaged, I would get a new one
