Bored dw10 block

[f.i.k 0]

Hi, I have small question... Maybe anybody know. Is all iron block same, or nothing? I want 96mm stroke in dw 10 block, and I want 87mm bore. But I little scary of it. Is not too big bore for dw10 with 85 original bore? Thanks. Sorry for my English.

2mm is quite a lot. However, the old Xu10 block at 86.00mm was taken to 88mm by a number of people on here, so if the casting is similar, you may be o.k I think I would be talking to the machinist who is doing the boring. Likely to have the relevant experience.

I give 16 (rfv) head to this block, maybe it's similar, but I don't know, maybe piston wall in block is thickness (I wish not. :-D) It will be good, thanks.

On the DW10 and XUD turbo there is water between the bores:

8 mm thick inter-cylinder with coolant passage hole at (C) and coolant plate at (D) to assist cooling of the top of the barrels

The only XUD block with a 86mm bore is the 2138cc N/A XUD11A but just like the XU10 there is only the small coolant passage hole on this particular block.

why a dw10 not an xu10?

 

xu10 is known to be good at 87mm

All Dw10 have oil piston spray. In xu blocks have it only 120, 112 and 108kw I think. 

Ok, if it's better, I have one rfs block. Use it. Thanks.
