Just picked this up sight unseen.

 

it has been opened up and had work done as the rods have been stamped. Turns over but has much rust.

this should be interesting.  what's the plan ?

 No plan. Just going to strip it so we can see what is inside as we so rarely see them in the UK. Or they are spoken about in hushed tones.

Is it the one with the 1071 stroke crank?

That's a A+ block isn't it? Same oil filter as the Marina/Ital inline engine ..

No strengthening ribs and the mounting for the generator is in the old position for a dynamo.  The oil filter position is about the same as the marina and the Mpi minis.

Nope. SA A.

Strange lump on the crank.

Oh look here

 

it seems it is a 1098.

With an 11 stud 1300cc head.  That's a real bitza...

 

edit - that's a SA 1071cc S style crank.  Makes a bit more sense.

How come the SA stuff is so different to UK stuff.
I thought it would of made sense to standardise all bits no matter where they were going to be used.

These were not made in the UK.  Their Minis were also quite different. Their MK3 had a hornet/elf back end. And there were others that had the elf/hornet front but the Mini rear.

Yep basically a 1071s motor. Though I think the head was made 11  stud later on.

 

loads of rust but it dose turn easily.

The reason for the SA 1100 engine was that they could use the same block & head and make 2 different engines - 1100 and 1275. They only needed to swap the crank and pistons (similar concept to the 998&1098 engines)

The SA 1100 engine had heavy pistons with a much bigger wrist pin height, and weren’t considered to be performance engines.

I have an SA1100 crank for my next engine build and it’s a 70.0mm stroke, which makes it a 1096cc engine. The bearing sizes are the larger 1.75” (unlike the S engines that used 1.625”). The lump on the crank web is a standard feature
