Cosmic73 Posted December 15, 2023 Share Posted December 15, 2023 Hi, can anyone recommend std piston rings for a vq35de? OEM are rare and expensive, I've seen Wiseco and CP ones but I believe these are only compatible with Wiseco or CP pistons? I've also seen Hastings ones on eBay for £100ish I've no idea what to get.

Cosmic73 Posted December 29, 2023 Author Share Posted December 29, 2023 Seriously, can no one recommend piston rings for a revup? ☹️ Quote Link to comment Share on other sites More sharing options...
Willsy1980 Posted December 29, 2023 Share Posted December 29, 2023 Personally, if using OEM pistons then i'd use OEM rings. You really don't want to be rebuilding it twice for the sake of rings. Or just buy the Wiseco piston and ring set, more cost but at least you know its right 1st time 👍 Quote Link to comment Share on other sites More sharing options...

They were discontinued by Nissan years ago and I can't even find aftermarket ones anywhere, including US suppliers. IS that what everyone doing a revup rebuild does? Fit new pistons?

However the Amayama link is helpful and they appear to have revup rings, thanks 👍 Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted January 11 Author Share Posted January 11 After ordering the rings from Amayama, they've told me there's none at their supplier so that's me totally stuffed. Can anyone tell me what options I have? -Are there any rings at all that fit revup pistons? -Are there any piston/ring kits that will work in a revup block?

Willsy1980 Posted January 12 Share Posted January 12 I hadnt actually looked into them, but id be looking for alternatives to those. Unless you want to drop £6K on them 😄 Can buy another Z for that 😆 Quote Link to comment Share on other sites More sharing options...

It appears they may supply non forged at a much cheaper £1k. https://www.wiseco.com/product/auto/pistons/professional-nissan-vq35de-piston-set-95-50-mm-bore-2/ Is anyone aware of other alternatives?

Cosmic73 Posted January 13 Author Share Posted January 13 Yesterday I ordered a set of Wiseco forged pistons from Concept performance only to cancel it a few hours later due to a 6 week lead time. I'm only running stock power so forged pistons may be pointless. I've seen these OE spec pistons for half the price which I reckon should be fine. https://www.ebay.co.uk/itm/112600053511 Quote Link to comment Share on other sites More sharing options...

Cosmic73 Posted January 14 Author Share Posted January 14 If you mean conceptua, I've just ordered a refurbished crankshaft/bearings, OEM timing kit, head bolts and gasket kit from them. It all arrived a few days back and looks as described. The crank & bearings are now with Knights engineering, along with the block and con rods for them to check the bearing clearances so I'm hoping to start rebuilding it by the end of the month. 2 Quote Link to comment Share on other sites More sharing options...
davey_83 Posted January 14 Share Posted January 14 Sure do, sounds a good haul - nice one. Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted January 15 Author Share Posted January 15 The piston/ring set from Conceptua are for DE (non-revup) engines and 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? https://www.ebay.co.uk/itm/112600053511 Quote Link to comment Share on other sites More sharing options...
