L20 connect rods

[Alan Pugh]

I can confirm the length when I get home from work but I do know that the L20A rods are not 133mm.

L14, L16 & L24 are all 133mm.

Rod lengths for L series engines

L13 139.9

L14 133.0

L16 133.0

L18 130.2

L20A 128.0

L20B 145.9 (can not be used on L series 6cyl cranckshaft)

L24 133.0

L26 130.2

L28 130.2

Hope this helps those that want to interchange parts.

Alan, where did you get these specs from?,

some are totaly different to the L6 calculator from the Sydney Z club. This is why I need confirmation from a manual as I'm starting to think that the calculator could not be all that correct.

Sure is a wealth of knowledge over the web about these old scoots. I am still in need of the L20 (6) connecting rods. Or if someone has 89mm pistons that use the L24 connecting rods in combination with the LD crank I would be interested in getting them from you. Note that I do not desire plain ole 240sx pistons. The last thing I am going to do is use a piston from a non-horsepower inspired car in my ultimate 3.1 liter build. Keep the posts coming

I am also building a stroker with the LD-28 crank, but I'm only going .040 over and should end up with 2964cc. I wanted to fit in the longest rod that was physically possible. So I called Carrillo.

They had some and listed them as L-16's. But these are 140mm (5.511") long, and I thought L-16's were 133mm long. I then called JE Pistons and had pistons made to match the rod length and stroke. Look at the picture and you'll see there is no way to fit a longer rod in an eng. with the LD-28 crank. And yes, I had to rob a few piggy banks to get it all.

L14,16,20,24,28 All have there little differences. Just so happens the pistons I got have the pin height specified for the L20 connecting rod. I guess I will have to source these from overseas because I cannot justify custom building some rods that I know were in common place engines.
