I have been searching for a while for a 3mm head gasket. Do you guys know where I could find one under $400? Or is this price about right?

This is one of the few things left before I drop in the turbo.

Thanks

thats actually how much they really are,
i think the 2.5mm ones are like $300
so a 3mm would be right around 375-400. call up SRT see how much they are there.

Yeah I just check thier website and its a 2.8mm for $295, I think so far this is what I will make do with.

How much of a difference will .2mm make? Is it worth $100?

We no longer use the 2.8mm HG. We currently use the 2.5mm HG and we sell it for $225.00 SHIPPED. And best of all we have it stock ready to ship. :)

Whats wrong with the 2.8mm for SRT to stop selling it? Did it cause problems?

Please do not assume anything was wrong just so because we stopped using it.

We switched because the 2.8 was lowering the compression just a tad more than we wanted.
as far as compression goes, is this pretty accurate

Stock compression is 10.5:1 on the IS. I believe the gte hg is about 1.5 mm.

The following are compressions with just a hg and ge stock internals:

1.5 mm- 9.4:1
2 mm- 9.1:1
2.5 mm- 8.8:1
3 mm- 8.5:1.

So my 2.8mm should put me around 8:7:1 huh. Works for me, since I'm only running 18psi.:cool:

CR Ratios with various HG and Stock Internals:

1.5mm HG >>> 9.35:1
2.0mm HG >>> 8.97:1
2.5mm HG >>> 8.6:1
2.8mm HG >>> 8.42:1
3.0mm HG >>> 8.29:1
2.5 mm looks like the way to go.
thanks for clearing it up :approve:
