how long do you have access to the 370z sasha?

Those gaskets are horrible . They blow out . Has happen to me many times .. Motordyne stop using them for that reason..

My goal is to have it off the lift by May 1st.



Never had an issue with those, as I use them on the 350z kits. The key to a non metal gasket is to go back and re-torque them after a couple of heat cycles. You do this because they compress a bit, and there is not as much force clamping them down.

The car that is being worked on had Stillen headers, and aftermarket test pipes. These were leaking a lot with the metal gasket.

I will see how this works out and as mentioned earlier, nothing will be sold untill this kit is working perfect.

:tup: on the way you work.

Many companies release products that are half-assed which only causes more headaches.

That's why I am asking, yes the Berks gaskets are HORRIBLE on the 370. They blow out left and right. The 350 has no problem with them.

I know that you are mainly a 350 guy, and they gasket issue is 370 specific. This is why I am bringing it to your attention.

If the factory gasket is an option please try to work that into your system.

this is the factory 370Z gasket.

The gasket is one of my main concerns, but then again i never went back and retorque them after a couple of heat cycles.

Flyboy, that does not look like the OEM gasket, the OEM one has a black rubber ring around the inside.

This is what mine looked like when i took it off.

I've never seen a gasket like that on my Z. Is that what you have between the stock headers and the cats? When I put my Berk HFC's on the factory gasket looked just like the Berk one but the Berk was a bit thicker.

I went through 3 sets that looked like that ..

Flyboy is correct, that is the factory gasket as per Nissan parts departments. It mounts between the lip of the factory cat and the beveled surface in the stock exhaust manifold and is pressed between the two creating a seal.

Personally I also went through a few of the gaskets Motordyne supplies with their ART pipes until I installed the motordyne gasket WITH the stock factory gasket carefully positioned and tacked up with high temp gasket maker and so far have had zero issues in 3 or 4 months. Compared to the Motordyne gaskets lasting one dyno tuning session on my SCed car.

If these are such a problem, I would use high Temp RTV with the Berk gaskets. The kit will come with a tube of it anyway for the oil pan spacer, and the rest (penty left) can be used on the headers. I know for a fact that the high temp RTV will now blow out, and a lot of guys use them right on the turbo inlet flange.

But again, the berk gasket should work just fine, and needs to be re-torqued after heat cycling.

Great :D Keep up the good work, also upload more pics :tup:

the gasket I posted is what I took off, there was no gasket like the ones that you guys are posting...

I am currently running RTV BY ITSELF, and so far it has held up.

those look like Berks to me.
