Dave I have a 2.3 complete engine if it helps 24000 from new. It was in my car, so I know it's healthy, don't know if it will fit in yours thou.

Still undecided as to which route to go.new engine is unnecessary. I picked up a spare head b4 xmas. There is a just a block on ebay however for darton liners i would reuse the current block as the cylinders get machined out.
I think i am leaning towards longevity so lower pressures but higher rpm so darton liners seems excessive.
I would have a word with Shem, see if he's got any of his closed deck blocks left.
Thanks Jim but pressing them out isn't gonna save much money, as I suspect the engineering time required to re-introduce to another block will be as expensive as starting from scratch.
Bought a 2nd hand block from e-bay in Germany from a 2003 S60.
Going to get it shimmed and honed and go from there. The oil/water mixing is only since the reassembly last year - never run properly. I will check the wiseco gudgeon wrist pins and see if they need replacing but bear in mind the reassemble engine has less than 5 miles on it. I will get new shells anyway, as the new block/crank ladder will be different.
I will get in touch with Tim or Shem to get the new block shimmed or closed completely.
Fingers crossed that the head is not cracked.
I found Shem's closed deck mod on e-bay.

they do look a thing of real beauty in real life, they are a really professional job if mine wasn't shimmed already i'd be going closed deck
The annoying things is I asked MJA to put in some deck support when they were doing it the first time. No point crying over it now.
My only concern about closed desk is the issue of cooling.
I will be going down the Evans waterless coolant route this time anyway.
I personally think Closed Decking is not necessary. If you really want to go down that path then there is other options which remove the cooling discussion of is cooling reduced or not and you can still have the liners shimmed as well http://www.kaplhenke.com/collections...-reinforcement, Yes it's for a 2.5 block but I have also seen them in a 2.3 block I just can't remember who it was who had it?
A big freeze would help all remaining components of your build Dave
I am also looking to the cryogenic processing you pointed out.
There's a massive mud slinging fest over on Swedespeed about block guards : http://forums.swedespeed.com/showthr...-R-2-5L-Status
I have no real clue if it's worthwhile or not, but I suspect not - certainly for most of us.
Amongst all the poop flinging was a link to a Polish firm doing a similar thing ; http://satistech.com/offer/closing-volvo-engine-blocks/
That seemed to appeal to more folks than the other way on that thread. I don't know what Shem does to be fair.
They cryogenic process is interesting another option for you is with the new block to shim and also add extra support around the clyinders in the water jackets
A friend who builds and runs cars in a BMW series used to go though components at an accelerated rate gear boxes mainly used to last 3-5 races he started using cyro treatment now boxes last hole seasons with refresh before the next season, he also has dipped pretty much hole engines in parts and his mechanical success has been excellent!
Another mate is now sending his O2J golf box away as they keep failing so will be able to see what the affects are on a normal box very soon as his last box only lasted 2 track days and it was given a clean bill of health after a rebuild so we will get to see with in a 3 months the results
That made for interesting reading Nick!
Tim runs just a shimmed block no other decking or nothing like it and runs over 400 bhp all day long and has never had no issues with liners splitting, there was another option as well on the engine build guy on Chanel 5 screwed studs down the side of the liners in the cooling jackets which was supposed to help but was running close to 6 or 700 bhp can't remember which?
Cheers
I remember watching that also while looking at videos on net at freezing there was a few open deck blocks with that method of bars in the water jackets for extra support being used in motor sport applications.
Personally I think Tim would be the best to ask on this situation as ypu say he's running the sort of power levels dave is wanting to achieve.
