Do you know what measurements they are in terms of thickness and so on?

I have been in contact with Total Seal, who were very helpfull, and seem to think they will be able to help me with off the shelf items.

Not sure what bore you have but I've been using 94/95 mm total seals on quite a few engines

. Guess it depends on your ring grooves. Forget omega, effing waste of space imo.

Hi Ian,

I was trawling through the previous posts about piston rings for Omega pistons. I see you went down the JE route without success (my engine is a JE early 3.9l coversion with 93.5mm bores).

Did you have any luch with Total Seal rings in the end?

Cheers,
Gary.

Im just in the process of trying to sort this at the moment.

I did some more digging on this. Firstly I spoke to Omega Pistons directly. Sounds as though, although they supplied the pistons to JE, they didn't supply (or are able to supply) rings.
I contacted JE who are able to supply rings for 93.5mm pistons/bore at £210.

I will go down that route if I have to, but Omega pistons hinted at the fact that they thought standard rings (ie 94mm OEM) could be used, I am assuming the ring gap just needs adjusting???

So, does anyone know what ring thickness the standard 94mm (ie 3.9/4.2l) piston rings are? The current ones in my omega pistons are 2.0, 2.0 & 4.0mm.

I do not wish to thread Hi-jack, but may I just ask. How do Omega after market cast pistons compare with OE cast pistons and forged pistons in terms of their suitability for performance use. I wouldn't want to free rev an engine with OE pistons for example past 6500 rpm, they tend to let go of their crowns don't they and there is no way I can afford forged ones.
