whats the bore and stroke of this engine?

85 * 86

The bore & stroke of the Nissan L20 engine is listed in my ACL engine parts catalogue as being 77.95 x 69.7mm
I'd call it a nominal 78 x 70mm
The dimentions remain unchanged for the L20A, the L20E & the L20S, & no, I have no idea what the diference is in these engines that warrants a diferent engine code.
The L20B has a bore & stroke of 85 x 86mm

In Nissan engine code usage, endings with E mean EGI (Nissan's term for EFI), and S means carbureted. So L20 and L20S are the same since they didn't start using the S until later to distinguish it from E.

L20B = L-series four-cylinder 2-liter
L20 = L-series six-cylinder 2-liter

I betcha he's talking about the 4cyl...

but since everyone is being pedantic, you left out the L20ET, and the turbo diesel LD20T 4cyl.

thanks guys. yeah i meant the 4cyl one.

L20B = L series 2.0L 4 cyl
L20A - L series 2.0L 6 cyl

ok cool.

but why does the engine have L20Axxxx stamped on them?

Quote: Neither of these two engines are listed in my older edition of the ACL catalogue.
Out of curiosity, whats the diference between being pedantic,... & answering the question that was ACTUALLY asked? I seem to lack the ability to read other peoples minds, & yes, i guessed that he 'may' have meant the L20B, which is why i confirmed the specs, but i did not KNOW that, so i amswered the question that was posed in the post. Why is there a problem with that?
