Hi everyone, I'm a Noobie, based in Southam, UK and currently working on a 2006 350Z-revup engine rebuild due to engine knock.
If anyone's interested I'm documenting the rebuild on this UK 350z site.
https://www.350z-uk.com/topic/130121...ebuild/page/3/

The reason why I've joined this site is to hopefully get some advice because the silence is deafening in the UK.
Basically, i just can't get a set of std piston rings for my stock revup pistons! No one in the UK and non from US, i've contacted eg Z1, Concept etc and they don't supply them either as OEM (discontinued) or aftermarket.
I'm totally stuffed. I've seen some on ebay, but they're brands i haven't heard of.
Please can anyone help? Much appreciated.
Neil,

 

Wow, no replies. I didn't expect that.

 

Not sure if they will ship over there

Thanks for the link but the rings they show are the wrong part number and the 13300-8J100 might be non-revup.
I've concluded that you have to buy new pistons & rings as a set which then fit all versions of the engine.
I'll be ordering a set on Monday., thanks

 

For an OEM application?

 

yes, OEM, I'm keeping the build at the stock 300hp and simply honed the bores which have barely changed from their original grade2 tolerance

 

I've found a piston/ring set from Conceptua for the DE (non-revup) engine but he can't confirm if they're compatible for revup.From what I've read on various forums, non-revup (DE) piston/rings will work in a revup block.

It's only the original revup pistons that need their own specific OEM revup rings. Is that definitely the case?

So, can anyone tell me if these DE pistons/rings will work in my revup block?

I appologize for the delay -

I use Hastings Rings - I’m using them on a small rebuild on a spare block I have and Ive used them on a buddies built block as well.

I dont know if the ring lands are the same size between the DE and the DE RevUP engines but I would imagine you could just use their online catalog to determine this

Thanks for the link but they appear to be 2007+ HR only.
I've ordered a set of Wiseco 95.5mm 11:1 CR pistons and rings which I've been assured work in a revup block, we'll soon find out anyway!
