Dear rx7club,
I have been a year long lurker from Italy, reading all I could about this magnificent car.
Now that I got ahold of one of my own, I decided to try to improve this already brilliant specimen, S4Tii.

Atm I am going to port my wastegate, did extensive research on the forum but still got some questions left.

Some don't change gaskets and some do, what gaskets and rings would I need to change? Also looking at diagrams I couldn't figure out the part numbers either.

Wouldn't mind if some expert chimed in to give his 2c.

 

It depends on the condition of the gaskets. All the stock gaskets around the turbo are multi-layer which support multiple uses. If they are fairly fresh upon removal then they can be likely reused.

However if they are original to the car, then likely they have been baked into their current shape and will need to be replaced.

Manifold to engine gasket: N318-13-461
Turbo to manifold gasket: N318-13-711
Turbo oil drain gaskets: N236-13-638 (two needed)
Turbo to exhaust gasket: N318-13-491A

 

I feel honored to get a reply from the rx-7 guru himself, thank you very very much.
