need peoples thoughts on COMETIC gaskets,

i'm thinking of getting them to make me some custom multi layer steel gaskets for the 4e/5e engines, as hopefully there prices will be cheaper, than buying them direct from japan from the likes of zep and cruise.


so if peeps could post there thoughts on this brand of gaskets, it would be much appreciated.

pretty sure COMETIC make a lot of good gaskets, cosworth engines ring a bell with that name lol.

IF they are a reputable company (which they are) then there is no reason why they shouldnt be used :)

regardless of brands, its the quality and relaibility of the product that i think most people are concerned with, adn zep cruise etc, i have never heard a bad thing said, unless i missed something.

do it cos they are very good quality gaskets


1 thing though dont tell them
how to make it

tell them specs of cars etc or boost levels

so they can use there knowledge on how to build the best

they can

funny enough cometic gaskets have got a pretty bad name on the gti-r forum's.. as they dont have a colapsable sealing ring around the chambers and people have had alot of probs with them blowing across cylinders.. if the head and block are skimmed they seem to be ok.. but this is just on sr20's. unsure on other engines

also if i do end up getting them to make it, i would only tget them to make the gasket in one size.

i settled on making them 1.2mm as i feel this is a good all rounder, what do others think?

I'm after a 1.4mm Gasket suitabe for a 5E build @ 1.8 bar, if you need a tester *cough* *cough*

sorry i need to ask,

if your running forged internals, there super strong, what would be the point in making the compression even lower by fitting a thicker gasket?

when the pistons have a 10 cc dish already

I need the 1.4mm HG to get the compression down to 7.5, also will be putting Nitrous through the system.

5E even with 10cc dish runs close to 4E compression

edit: Turbos going to alot beefier than my current TD04 :)
