PRV Concept

Hello, I'm Ville from Finland. I have a project, my Volvo 760 with B280F (2.8) engine, I have also 3.0 litre ZPJ-engine from Citroen XM, mileage is about 3000km, so it is very impressive condition. Like a NEW! I will combine them (bottom-end of block and i'll maybe use mechanics valve lifters/rocker arms from B280F)... so that I can get a 3.0 liter engine to my RWD-Volvo. And also later supercharged to it, with Megasquirt EFI and E85 which is high-octane etanol fuel.

Welcome here
Solid valve rockers is what Renault used wit the Z7X (3.0) turbo.
With E85 knock will not be a problem so you can probably keep the stock pistons if you don't blow too much.

Yes, thanks. First of the all, I'm thinking keep stock pistons and beams. (First version have slightly 0.3-0.5bar of boost.) Stock component should keep this.. but in future i will need forged pistons and h-beams. Is it some place (France? or somewhere europe) where I would to buy forged pistons to 3.0 PRV-engine? Compression ratio about 9-10. And also H-Beam rods... I will be very thankful...

Welcome on board

CP pistons can make you pistons.
For the connecting rods the ZPJ have the same forged rods as a 200 hp ZPJ4 or a 268 hp Z7X-726 twin turbo so you can probably just go with a good balancing and a shot peening on the stock rods.
