Could anyone suggest, what nozzles should be used with this combination:
- ASZ engine block
- 81mm pistons
- ported cylinder head
- 12mm fuel pump with de143 camplate
- 2260vk turbo

What size nozzles should be used for street use, so it would not smoke too much? 0.360? 0.341? 0.320?

If you want everything out from that turbo (310bhp or so) use 0.320.

0.280 can do 280-300bhp when maxed out.

15 or so if you want 300bhp.

What camshaft do you use?

Stock camshaft from a 81kw (ASV) engine. What camshaft you would suggest?
Also could you recommend, what head gasket should be used to gain the AFR 15? Or is it gained with some other camshaft?

Do you mean Compression Ratio???

AFR = Air Fuel Ratio.

You really need better camshaft. Any aftermarket 9.5-10mm cam would be ok.

It appeared that this camshaft is not available on the store anymore. One question regarding the angles what are marked for the cams. Are they related somehow to the valve lift? Is any 9,5-10mm valve lift camshaft ok to use and what is the difference?

what happens with the camshaft which has the 10,4mm lift? I would really appreciate, when someone would explain a bit on the camshaft selection.

Use camshaft that can be used with stock pistons and valve springs. Many 9.5 - 10mm models can be used without bigger valve pockets in pistons.

You can use stock pistons with that 9.9mm camshaft.

What 81mm pistons you are going to use? Different pistons, different compression ratio. Crafter piston make lowest compression ratio, below 17:1.
