How thick is a standard 2.0 16v XE gasket? 1.3mm?
How thick is a standard 2.0 8v SE gasket? 0.8mm?

SBD sell a 2mm gasket for £106+VAT. £124 yikes.

I need to add 1-1.3mm between the top of the piston and the head. D**k at SBD told me that a mate of his stuck an 8v head on a 16v block and used two normal gaskets without any trouble. But I'm not happy with that idea.

Anyway, I think that I'm probably going to end up with a mixture of skimmed piston and thicker gasket so that I can raise compression further in the future without touching the pistons.

*thick moment*

Tom why you wanting to lower CR?

I saw your other thread stating .5mm piston intrusion into head, but is this not the same as the 8v?

std xe gasket is 1.1mm

You could just run LET pistons and solve the problem

8v pistons have bowl to lower CR.

Will LET gaskets be ok ? could use 2 x Z20LET ones, they're steel layered and would be 2.0mm thick together ?

C20XE, C20LET and Z20ET gaskets are all 1.1mm thick (I have them sitting in front of me). If you want to fit double Z20LET, you need to remove the 4 rivits holding the 4 metal layers together.

I don't like double gasket idea. Latest plan is to have pistons machined to match 8v ones.

ive compared a z20let gasket to an xe 1 and a fair few holes dont line up... i really cant see how it would fit and work properly

 

[ChrisB]

The holes don't line up on a LET either, it has to be modified AFAIK.

 

[PhilM]

the larger ones for the water jackets wouldnt b a problem, but the smaller ones next to the pistons are only slighty out - this would leave an oval hole there

Must admit I haven't laid the C20LET ontop of the Z20LET to see if there are any differances.

All I know is if you have a KS head, you need to remove the rivits on the Z20LET gasket. If you have COSCAST head then you can leave the rivits in.

 

[tomstickland]

What about the 20SEH? Is that 1.1mm too?

 

[tomstickland]

Any idea on what the 20SEH thickness is?
