What L series is this?

I was playing with my L-engine calculator, and i saw some stuff that i just dont know....

What are L16 rods? L14? L18 L20a? FJ20? and all those things??

For 4-cyl L series engines. Like in dimes and 210's and stuff.

Like: 1600, 2000, 2400, 2800, etc...

Is becuase the deck high with the L28 crank and the L16 rods is perfect! to fit into an L24 engine and increase displacement from

stock L24 - 2393

L24 with L28 crank L16 rods L24 pistons HKS 1mm Head gasket - 2565

compression L24 E88 head - 8.76 : 1

with above - 9.28:1

hows that?

if you want even more compression put an E31 head on it. Personally...i would feel more comfortable overboring the engine before i start throwing in a whole bunch of different parts, just my opinion...

Hey wish, where is the calqlater? on-line? I have just used zgarage.

Where are the CC's of the heads at? I can't find it all of a sudden. I saw it somewhere...

The calculator should be in the downloads section. That's where I got it from anyway. Lot of fun to play with when there's nuttin' else to do.

BTW, I wouldn't think the 4 cylinder L series rods would be anywhere near strong enough to put in the L-24 thru L-28. Not only that but you would run into piston problems. Not sure if the wrist pin is the same on all L series or not.

Hi guys in reading your posts, the L-16 and the L-24 rods are one in the same. Datsun went to bigger rod cap bolts on them in 72.So the program has a flaw in it.The SSS L-16 is an L-24 with two cylinders cut off.The L-18 and L-26/L-28 rods are the same.

What I never understood is, why did Datsun make the L-26 with a 240 bore and an L-28 stroke when they could have made one with an L-28 bore and L-24 stroke.I'd kinda be like a 302 chevy or ford. 240 Al

what is actually involved in over-boring an engine?

Im not talkin bout just throwin stuff in, im trying to work stuff out, see what i can do to increase the power of the engine, and i like the fact that it probably hasn't been done the L28 crank and rods in the L24.

over-boring the engine is a pretty simple task done at an automotive machine shop. All they do is mill off the desired amount off the cylinders, then all you need is bigger pistons i believe

if you have the calculator check this out....

L24 block

Ld28 crank

L28 rod

L28 flat pistons

E31 head

this leaves the deck height at 2.030mm

add a 2mm head gasket, your at .030 mm ( calculator doesn't figure for head gasket deck height )

check out the compression and displacment...i know 11.5 is high

now, flip the head to an E88...and fly cut the pistons .5

still 2.7Litre's displacment, but now the compression is at a workable 10.41 : 1 =)

what do you think?

ive heard of boring a L24 out to 2.8L and putting a E31 head on...that gives you good displacement and very good compression....10.1 is really pushing standard pump gasoline's limit

The 240 block/bore and the L-28 crank has been done that was the 260Z motor.It's the reverse that datsun didn't make 280 bore with a 240 stroke.The compression ratio would be more within reason. 240 Al
