Im sure Im speaking on behalf of many people here on this site
"thank you for the pictures and effort in cutting an otherwise
good repairable A15 engine!"

You can see that there is no cooling beetween the 1-2 and 3-4 cylinders
and they actually touch which means the same could be done the to gaps
of 2-3 cylinder in the offset machining.

Now I ask Is it possible you can go further and make another cut at the base
where the sleeves/liners would slide into in a wet sleeve setup?

eg. the pics below show the base of a renault engine and the sleeve used for
its big bore conversion done by Orger engines in Victoria.
On an iron block I wonder if its necessary to coat is with something to stop
corrossion? eg. Would penetrol work? for once the cementing occurs at the base
the lube will be stuck/trapped in there keeping the iron lubed.

Rubey best ask Lemonhead if the extra few mm of the offset bore could be taken
up by the piston pin but most likely crankins need modifying. Im thinking of
using an early a12 block with the 77mm crank for 1666cc and no engineering
but the a15 at 1796cc is just too good to not engineer as 1488cc with turbo or
e16 cranked 1997cc quad-carbed NA snarling torque monster. Its opens a totally
new can of worms to A series benchmarks/possibilities yet outer dimensions of
the A15 would remain so small and compact!!!

I cut my engine to pieces tonight and i´m impressed by the cylinderwall thickness! It varies from 5,5 - 7,5mm.

Are these block thicknesses on a standard 76mm bore A14?

what a beautifully kept datsun! and clean garage

1800cc in NA id be happy with but with boost it would spool up a t28rr
so much quicker and feed it for a better part of the midrange.
It would suit an otherwise oversized oval ported head that are usually
to big for 1600cc but probably just right for an extra 200cc and boost!
I must get out to the wreckers this week for the 83mm liners.
Ive got word the Pug 205 and 405 liners from the 8v engine can be bored
out another 1mm with plenty of meat left over. The 16v headed engines
have the same liners but with cooling fins that need machining off anyway.

The 405 liner takes an 88mm stroke

In the second photo, is that a postie of some descripton in the background?

I kinda looks like one. The handlebars and headight a wrong, but it could still be a honda cub i spose.
