Mandic 0 Posted June 27, 2007 Hi, I'm looking for 85mm liners and there is a company in France which have them. They are graphite cast, so should be stronger than OE ones. Now my question is, has anyone any experience with them. I'll use them in forced induction applicattion so do You think they will hold 1 bar max? They are stronger, but they also have thinner walls.

Sandy 189 Posted June 27, 2007 For forced induction I would prefer to use an Iron block unless you keep it 83mm and low boost. Share this post Link to post Share on other sites
welshpug 1,626 Posted June 27, 2007 but then the WRC engines are based on the XU7 which is an alloy block with liners... Share this post Link to post Share on other sites
Mandic 0 Posted June 27, 2007 Well yes, I agree that for FI route iron block is a way to go, BUT I would really prefer ally block, but I'm not happy with 83mm bore as 85mm one brings so much banefits (unshrouded valves, more capacity, ...), plus I will not run so much boost, thinking something around 0,8 bar. This also means getting new rods and pistons (just to be on the safe side regardign rods), where if I go iron block I only need new pistons, as rods are fine. But then again, building something different is very tempting. Cheers Ziga Share this post Link to post Share on other sites
brianthemagical 1 Posted June 27, 2007 i'd ask the company that makes them what they think the liners will take. othere than form experiance i don't think anyone will be able to give a good answer as you say they should be stronger but don't give anythink more. if all else fails just build the engine and wait till it breaks, they can't cost that much, surely.

Sandy 189 Posted June 27, 2007 I wouldn't use the WRC engines as any kind of benchmark, they are a long way removed from what you can get off the shelf. Share this post Link to post Share on other sites
snillet 1 Posted June 29, 2007 but then the WRC engines are based on the XU7 which is an alloy block with liners... XU7 excists as both alloy block (same as XU5 by the way, have both in my garage) and cast iron block. The alloy was used on the 8 valve engines and the Cast iron block was used on the 16 valve engines. Share this post Link to post Share on other sites
welshpug 1,626 Posted June 29, 2007 XU7 excists as both alloy block (same as XU5 by the way, have both in my garage) and cast iron block. The alloy was used on the 8 valve engines and the Cast iron block was used on the 16 valve engines. nope, not recently anyway, it was an iron block back in the early 80's in the 305, and when Peugeot used it in the 205 T16, but since the mid 90's its been alloy, and this is the basis of the WRC engine, but I agree with sandy, the WRC engine it quite far removed from what's available in the public domain so to speak.
