Question i have is what difference would different sized pistons etc make i have a set of m20 ones laying around that i was going to try and put into the m10 but not sure if it would work or not any ideas?

I have heard something in the past about vw beetle pistons...I think.....
Or maybe I dreamt it lol
M10 can be a cracking motor if done right, I was gonna build one with my old lump but my brother weighed it in!!! was gutted as it had a schrick cam in it!

It is meaningless to ask; which is real, 'real' or imaginary? It is simply a matter of which is the more useful description

i wonder if any one on the vdub scene would know about the beetle ones then might be worth finding out at the minute i have pretty much everything sitting here so i thought i'd have a play around with it and see what works

It's complicated
If you have an S14 crankshaft you can use 92mm pistons from an M30, but you need to modify the timing cover to fit the S14 oil seal, then deck the block by 0.5mm and mod the chain/tensioner. You can also use a 2L crank with VW aircooled pistons but need to deck/mod again. You can use a 2L crank with 2002 pistons, but unless you have the right head you will either have stupidly low compression or piston Vs valve issues.
The best way I can see to do it is to contact someone who does custom pistons like top end performance in the USA, and tell them what crank/head you have, and they will make pistons to match.
Hope that helps
