So Today after work Im going to start the whole re assembaly process of my KAE-T Finally, but I do have some questions.
First off I took apart my whole intake side and removed all the emissions crap including the secondary butter flies, so I now only run with one vacumm line and thats for the FPR.
In anycase I went online and ordered a full gasket set for my intake and exhaust side. Now I also have some of that copper liquid gasket stuff for high temps that will resist up to lik 1200 degrees or something. Anyways my question is, should I put a really thin coat of that stuff even though I already have gaskets too.
And my second question is, I dont have the gaskets for my exhaust manifold to turbo and downpipe to turbo, is it ok for me to use that high temperature liquid gasket on there? I have used that stuff on my friends 5.0 Mustang headers and it's been holding up for over a year now, but I think a turbo might run slighty hotter at those spots.
Thanks in advance.
Gasket question.
Re: Gasket question. (S13FX)
High temperature liquid gasket can damage your o2 sensor so no go on that. Buy the right gaskets or dont use any gasket.
Copper liquid gasket (the spray) is used to hold the gasket in place. Use a light coat.

Re: (S13FX)
some liquid gaskets are not safe for o2 sensors. it doesn't matter how far down stream the o2 is.would you drink water from a stream that your buddy pissed in if he was a foot away from you or 20 feet?
OH I understand, thats why I see tubes of liquid gaskets sayin sensor safe, but if it says sensor safe then I should be good to go right? And would u recommend a light coat of that stuff on the intake side even though I already have proper gaskets for it?
And as to answer your question well you don't wanna know HAHA.

Re: (S13FX)
for paper gaskets i don't recommend any silicone. especially on a turbo car.the boost pressure can cause the gasket to be pushed out. i've seen it happen on a cylinder head that was painted. the paint would get soft when the engine heated up and caused the gasket to get sucked in when the engine was idling.for the most part, i only use silicone on things that are supposed to be sealed with silicone. some water pumps, oil pans, front covers. stuff like that.or in the corners of rubber gaskets if they are not flat and curve over a surface.for nissans i only use permatex ultra grey.for hondas i use honda bond or honda ultra flange.i try to say away from the cheapy aftermarket silicone.
+1 for Ultra Grey.
As for the turbo...
The best seal on an exhaust component is no gasket, but the surfaces must be perfectly flat. Because of the different rates of expansion between stainless and cast iron, I'd say use a gasket at the manifold/turbo joint on SS manifolds. If it's cast iron, don't use one.
The same rings true for the turbo/downpipe joint.
