L14 Rods

[nixcars]

A set of six L14 rods needed.

Hey Nick, What are you using those rods on? What did the L14 come out in? :devious:

Hi Nick,

i have a set of these in my engine, i tried last year trying to track down another set for spares with no luck. Try warren at allzed and see if he can order them from Nissan Japan, its about your only hope.

ive tried wreckers in NSW, QLD and VIC with no luck. The gerneral consensus being "ive never heard of an L14".

I have also tried for them in the states.

Your only other option is custom rods

Frank,

i believe the L14 4cyl was in a sedan body the same as the datsun 1600 aka 510. produced in very small numbers. im not sure what markets these cars were sent to maybe Alan knows?

the rods are longer than L24/L28 rods and are great for getting serious compression. they also make for better conrod/crank geometry and hence more torque.

Hi Nick,

I've got a few L14 rods back at home. As far as I remember, I have around 8pcs.

You could possibly mix and match a set of six out of the eight, but they have been messed with a little before I got them ( casting flash taken off / smoothed out, sanded ) so they need a little work. If you are going to race-prep them then they are already started....

I'm away from home on business at the moment, so if you can wait until I get back to London ( middle of next week ) I can dig them out and send photos to you.

These are genuine L14 rods, and the classic formula for a Japanese big-bore / stroke L6 engine. I can't remember the centre to centre length off the top of my head, but they are long ( 140 something? ).

I'll get in touch when I get back from Japan.

All the best,

Alan T.

Hi everyone,

Well for the second time today I am totally confused.

I have 2 books that list the centre to centre length of L14 rods as 133mm.

The only rods I am aware of that are longer than 133mm are: L20B at 145.9mm

The above rod is unuseable on L6 engines because the big end is 5mm larger in diameter.

L13 rods are 139.9mm and can be used on L6 cranks.

As I said I am confused on this and if my info is incorrect I hope someone can correct it as I don't like giving out the wrong info.

I won't share the first confusion of today for fear of putting everyone to sleep.

Alan.

hmmm,

im convinced L14 rods are 137 mm, with L24 and L28 rods 133 and 130.3.

i measured them when i rebuilt my engine and off the top of my head 137 is what i got, ill have to recheck that and get back to you.

Well here comes my apology.

The lengths of the rods becomes so easy when you start thinking latterally and taking everything into cosideration instead of believing everything you read.

All L series pistons have the same piston pin height of 38.1mm.

L14, L16 & L24 engines share the same bore size of 83mm.

L16 & L24 rods are 133mm centre to centre.

An L24 IS an L16 plus 2 cylinders. 16 divided by 4 times 6 = 24.

The stroke difference between the two is only .4mm

L16 stroke 73.3 L24 stroke 73.7

So if we look at all the above if an L14 had a rod length of 133mm with it's shorter 66mm stroke the compression ratio would be way too low.

To cut along story short if you take the info above and do all the sums an L14 rod comes in at approxiamately 136.7mm

I apologise for any missleading info or confusion I have started but I feel better now that I have corrected this.

Alan, you are very close if the measurement of 136.75mm that I have been given is the correct one.

Nick.
