Please help me to choose a Piston


Recommended Posts

Hello to everyone


Its time to rebuild my engine.

While im doing that i was thinking of generating in the same turn a bit of hidden power.

The head is already done (back on the block since 3 monthe to run in and try out if that what i did works) so far everything is going well,


The big question now is what kind of Piston should i put in my L16 Block.

I tried already to get a L20B but they are really hard to get over here in germany same as L18 or anything for thoues cars ;)

So i guess i have no other chance than build the L16.


I could get a Flat top piston from Zypern with a overbohr from 0.75mm

Or i could put a L20B piston in it.


The l 20 b Piston will have that deep dish 11.36cc 85mm bohr


What would run better?

More compression or more cubic capasity ? 


cheers Floro

I Know that i could take the L18 Piston. the problem is its hard to find.

and i can get a set of piston plus rings an everything from a L16 =83 bore oversize 0.75mm so that would be a 83.75mm piston with a flat top for 100€


doues it make a big differenz between the 83.75mm flat top to the 85 mm 4cc dished piston?


Not bad your german. I will put some pics up from the W115 but its boring its all stock

L16 .75MM IS GOOD GENUG!!!!!!!!!!!



L16 and L18 is the same to me. Its the Cylinder head that makes the power.  Unless its a L20 and the cylinder head.


In USA L16s cam with a 210 marked cylinder head and its very small valves and ports



When I was in Bitburg/Eifel I saw a 510 that was overturned on the side of the road.But back then I had a 78 3ltr Capri!!!!!!!!

L16 bore is the same as the L24 (240Z), they were flat tops from the factory.  L18 will accept the L28 (280z) flat top pistons, BUT it will be a 0.040" (1mm) over bore.  Good luck



L18/L20B are 85mm. L28 is 86mm. 



What you did, I see. Made it easier for new guy to see it too; fixed*
