I still have the engine in the end the pistons sit about 0-5 mm below the block the engine was put together so need to strip it and deck the block
I have not touched the engine for a long time as am still building the car here is a couple of pictures with this m44 engine installed when the car is done then will put stroker in the car, still sorting rear axle.
I have had the car 8 years now 2 children later say no more

Hi Ralph
Thanks for your reply.
The builder phoned me and said about CR before decking the block and said 13:1 CR will print your reply and show him.
The bigger HG could be a winner
Have m42 head with 6mm valves and solid lifts so will do the maths to find the answer will know more tomorrow.
Thanks again

Yes had an extension made with nut on the end.
Still trying to sort out how much to take off the pistons to change the 13:1 ratio?

Quick update done the maths and found that it has 13:1 compression ratio need a head gasket will keep the updates going when I get the headgasket.

Sorry for my mistake the conrods are from m52b28 which are 135mm I spoke to MM and they said take the 2.8 apart and use the conrods I did take a good engine apart to find the small ends wristpin gudgeon pin are to big?
I would have had to have the small ends re bushed for the s50b30 because they are 21mm as the m52b28 small ends are 22mm.
To make the bushes and put them in  would have been the same price as having the conrods made with 21mm small ends.

Thanks for your reply
I have watched your youtube videos nice?
I have had a m44 with light tune cams remap exhaust and 4.5kg flywheel was in a 318i touring so really made e36 318is touring sold it and he crashed it so got it back and put engine in compact was a great car really surprised how the compact was I never thought I would have 1 was more of a bet than a real choice.
I then made 2.8 compact that I drive everyday there is good and bad points for both conversions.
I had 328i touring and sold my m44 compact to my mate and the compact was just as quick round London.
To me the m44 was like a 2 stroke as the m52 is more like a 4 stroke in motorcycle terms.

Have put engine together today to find have to DECK THE BLOCK 0.5mm
to make the pistons level with the block.
Some  measurements
86mm pistons s50b30 they are 0.5mm below the block
135mm rods with 21mm pin new bearings
m47n crankshaft 90mm stroke in the block with the pistons is 90.60mm stroke
I have been looking for a long time to get these answers I know it is easy now but my engine builder friend has not done bmw engines before he likes old ford kent ohv and pinto 2.1.
It has been a mission to get this far have had lots of help on the way thatnks for everybodys help

Here is a pic before going to have the keyway cut have used stock diesel crank bolt seemed a bit short so will get the m40 washer and pulley machined a bit so more length in the crank.
The m40 extension cut off the crank and the washer for the pulley will have to drilled out to take the m18 bolt.
Putting engine together to check piston clearance next week.

Went to see progress today just a little question please.
I have 90mm crank 135mm rods s50b30 pistons I really hope this is correct?
Do I need to deck the pistons or thicker head gasket and he is asking me about c/r and capacity in the cylinder when at tdc with m42 head.
I have found all this in the past but can not find again I am trying to get the answers before dummy building the engine.
I have m42 ported head with 6mm valves and guides there are no valve springs will s50/52 springs work all so  solid lifters or can play safe with standard m44 head.
Only need the key way cut as all together just did not have camara more pics friday?

In the  pic the nose part was machined off an m40 crank now the diesel crank is going to be machined to the same diameter then a keyway will be cut so all the parts in the bottom pic slide over everything.
The oil pump pick up then the timing chain sprocket with a diesel crank bolt
here is pic of the nose with the oil pump sprocket.
When the block is together will see how much have to deck the block so see about c/r.
