Darton Sleeved H22 Block

[Ammo]

I call fake, I can't see any form of Darton sleves in there

Might be these if any

Part Numbers: 200-018 - Unflanged Stock Replacement Sleeves
Application: Honda Prelude H22
Brand New! Unflanged Darton Dry Sleeves for Honda Prelude H22A engines replace your factory cylinder liners with high strength iron sleeves, eliminating a weak link in your engine and providing you with the strength needed to get the full potential from your setup without losing any sleep worrying about cracking a factory sleeve and taking the engine out.

This particular model of sleeve is designed as a stock replacement sleeve, not a high power race engine. This would be perfect if you are just looking to get a proper cylinder wall finish without compromising the structural integrity of your block by removing material.

The others you'd spot even from those pics

Part Numbers: 300-018
Application: Honda Prelude H22A
Brand New! Flanged Darton Dry Sleeves for Honda Prelude H22A engines replace your factory cylinder liners with high strength iron sleeves, eliminating a weak link in your engine and providing you with the strength needed to get the full potential from your setup without losing any sleep worrying about cracking a factory sleeve and taking the engine out.

This particular model of sleeve is designed as one step up from a stock replacement sleeve, not a high power race engine. This would be perfect if you are just looking to get a proper cylinder wall finish without compromising the structural integrity of your block by removing material.

He seems to be quoting the details from these

Part Numbers: 400-160-P - 87mm to 90mm MAX
Application: Honda Prelude H22A
Brand New! Darton MID Sleeves for Honda Prelude H22A engines replace your factory cylinder liners with high strength iron sleeves, eliminating a weak link in your engine and providing you with the strength needed to get the full potential from your setup without losing any sleep worrying about cracking a factory sleeve and taking the engine out.

MID stands for "Modular Integrated Deck". If you notice the sides of the top of the sleeves are notched so they mate up flush against each other, providing a full rigid structure when assembled, but still able to be replaced individually if needed. As shown in the photo, the top flange has coolant passages and the outside surface of the sleeve contains "fins" that help reduce heat soak within the sleeve, helping keep the heat out of your internals where it could cause damage cracking, warping, etc.

He doesn't, selling on behalf of a 'friend' and doesn't really have much clues as to sleeves and stuff.

Might be obvious but I'm in discussions and very interested! But just unsure how good it is at the moment.

The old selling on behalf of a "friend" hmmmm
Unless he has paper work in my eyes it has the value of a standard block...

It's a shame he has no paperwork I don't think there's really any other way to prove its sleeved

Im with Danni on this one.... a friend with not much understanding of this stuff just happens to get a darton sleeved block..... then sells it signficantly below price? surely you could revive a paper trail if it was genuine (contacting original seller, getting copies or old recipts etc)

i see a standard block to me tbh

Doesn't look sleeved at all?

[nucleustylzlude]

I figured it would be the 200 series liners, not the flanged ones or MID's. They're supposedly 3mm thick walled, but it's whether they have been bored at all. It does look standard, but you can make out a liner, but is it the FRM??? It doesn't help with those crappy pics, I've asked for better, properly lit pictures showing close up of the 'sleeves' and block in general cos it looks like there's some corrosion on the top of the block.

Will most likely be a no go, but worth investigating at that price.

ask Rich at PAW to have a look i'd say

Sorry but what do you want me to say?

Its an early closed deck block that may or may not have had some sleeves installed and may or may not have had them installed well and may or may not have had them accurately bored.

Absolutely impossible to tell from those crappy pictures so unless someone wants to bring the block over to me for inspection I can't help here

[nucleustylzlude]

Exactly!

I've just got some pics off him and I can confirm it is sleeved with the ductile iron 200 series liners, 100% not FRM lined. I can make out some cross hatching from honing too, so it may looks to have been used, but again I'm not sure how they come from the factory. I've asked him to measure each cylinder top and bottom to give me an indication if they are stock (usually slightly smaller than 87mm to be bored to match the varying piston sizes), or whether they've already been worked on.

One pic worries me, it's either a crack in one of the liners that has been welded, or it's just a drip mark from some old coolant when the block was split. This 'could' be the reason for the sale of the block and 'lack of info'. We'll see.

@PerformanceAutoworks - Rich, any knowledge or experience of using these dry liners? Or is it more the flanged items or MID's? I 'may' (cough) have got myself some Wiseco 11.5:1's but they are 88mm. Darton suggest the liners to be used as stock replacements (87mm or oversize). But do you think I could get them bored to 88mm for these pistons? The walls according to the specs are 3mm thick, so it's losing 0.5mm all round. Any advice would be great bud - PM or reply here. Havn't had a good PM chat about all things H22 for a long time.

Cheers,

Rob
