Nice gasket, multi layered. Any special preparations in using this gasket?

 

Are the torque values and sequence the same as using the stock single layered gaskets for the n/a engine?

 

I found it often mentioned to use this gasket but no accompanied details. It would appear the STi installation has a different procedure.

 

I tried a search but can't seem to find the info I need.

use the torque specs for the heads that you are using, regardless of the gasket.

 

typically you will find suggestions to use the sti gasket in phase 2 2.2's and 2.5's that came original with the multi-layer gaskets.

 

the older ej22 in 90's models used the composite gasket, which was never prone to failures the same way the newer engines are.

 

Even when ordering a gasket for your specified model, any new one is superseded by an improved design. You should cross reference parts numbers between turbo gasket and whatever may pull up for your car and compare them with other models/years

Good call Miles. I went with the oe specs for the oe heads and have had no issues. Thanks :cool:

So do the new superseded 2.5 gaskets fix problem for good?

I don't know. I am using the 2.5 turbo gasket as recommended here. Seems all of those that recommend the turbo gasket have had no further issues.
