Title: Oxyboxer questions?
Post by: FIDDE on October 25, 2009, 22:09:52 pm
I have some questions about an oxyboxer case,first is it possiple to machine down the deck 10mm on
both sides to get the right deck.And does the 94 bore typ1 cylinders fit in the case without
machine job.Im aware of the wider headstuds.

No milling the case down 10 mm on each side will weaken the case too much in numerous places.
No the 94 mm type 1 cylinders wound't fit, but due to the wbx case is wider the cylinders have
to be machined in the case end. The cylinders can now be machined to fit the spigot bore in
the wbx case.

Ok... thanks for the info  :) I have a Demello 84 race crank and CB 5.5 H rods that im going
to use.Maybe it's to much job to go on a oxy,im looking at different case options.

It's a near perfect combo for an oxy boxer :). Machining the cylinder to fit the spigot
bores and deck height is the same as any other combo.  Just go for it  ;D

94mm Type 4 cylinders fit in the WBX case . You only have to do some work on them

Yes they seal very fine as long as the machine work is done correctly. Sealing surfaces in the top and in the botton of
the cylinder have to be parallel. On the 101,6x86 oxy engine I have build for a friend we ended up with less sealing surface
than 94 mm cylinder proberly will have and the engine is not leaking.
