I believe Jeff can make these in 95.5 as well.

Thanks for the Info.
I think BMW use the spark plugs to measure the Zylinder pressure. After ignition the look how many ampere they need to get a new spark. So they now the pressure

You can get special plugs that have inbuilt pressure sensors. V expensive.

I found this helpful regarding clearances etc.

Thanks for the link.

Think about my engine. Talk with the tuner from the dyno and came to the result that the clearance from my crankshaft is to small. So i will take them out and let it girnd to 0.1mm Main- and 0.07mm rod bearings clearance.

Start to make new gears for a bigger oil pump

Hi,

I also buildt up a 2.5l with 95.5 crankshaft.
I let my crankhaft balance by a specialist in Laakirchen, Upper Austria and he also said, that you dont have to use bob weights.
First he thought, that I need bob weights, but than he tried it without the weights on low rpm and he said it is perfect.

I'd go elsewhere.

You ABSOLUTELY need a 50% bob weight to balance the crank.
