L-Series Distributor Drive Question

[Kirden]

Alright, I'm wanting to use a KA pump for my LZ build. The information I've found shows that the drive for the KA pump is much longer that the L-series drive and that you need to swap the L drive onto the KA pump.

 

So, does the L18 have the same length drive as the L20B? I'm pretty sure my L20 block doesn't have the oil pump so I'm trying to see if I can scavenge the shaft from my L18 once the LZ is ready.

All you need to change is the pump. If you have an L18 just take the L18 pump out, if a Z22 block just use the spindle in it or the L20B.. and substitute the KA pump.

[Kirden]

So the L18 drive is the correct length for the L20 block? I got slightly confused with your response, it's been a long day.

 

Here's what I have. The L18 is the running engine in my truck. The L20 block is only the bottom cast section, no additional parts. Just need to know if I can transfer the L18 distributor drive gear onto the KA pump for the new LZ22.

okay, i think i get what youre asking. 

 

the L16/18 drive is shorter than the one for an L20, z20, z22. 

 

if youre going for LZ engine, im assuming z20/22 block, which is the same deck height as the L20. 

 

so to answer the question, the L18 drive will not work. you need one from an L20. 

[Kirden]

Thanks farmer, looks like I'm on the hunt for an L20 drive. Sorry I wasn't explaining very well, it's been a long day.

 

My LZ is technically a stroked long rod L20B, just uses the Z22 crank.

such a complete and direct answer

lol, even a troll can contribute... :lol:

I think the spindals are the same

 

My Nissan motorsportbook say the the same part number OE spindal 15040-21001

z20/22/24 is a different part number and z24 is another number after 4/85

Hainz it looks like you are correct. I'll try it and see but datsun parts llc seems to use the same one for all L series engines.

[Farmer Joe]

 found this info from last year... looked for an hour to find these pics..

 

They are???

 

 

 

 

Some rare early ones were brass and highly sought after for racing.

 

 

 

 

Well I checked and all L motors (4s and 6s) use the same spindle. The Z20/22/24 carb motors use a different number.

The early Z20E (EFI) uses and even different number.

 

Here's the rest of my collection... The 3on the far left are from Z24i and KA24E motors.

i guess this prolly just adds confusion to the question.. 

 

just ignore this... lol

[Kirden]

Farmer thanks again man. You're a great help. I dunno why everyone sayd you're a troll man. Now I can haz secrets to slamming my 620? :poke:

 

Honestly though, thank all of you guys. I was sorta lost on what to do about the spindle since these engines are so rare in my area. Glad to see you can still get new ones.

Kirden, here's what we did on my LZ.

 

-Z20E block

-L20 front cover

-L20 dizzy drive spindle

-KA-e oil pump.

 

 

Bolted together like stock.

1/ #15040-21001... L16/L18/L20B/L24/L26/L28 all use the same spindle

2/ #15040-W0400... Z20/Z22/Z24 Truck motors and 8 plug Z20 and Z22 in the S110. These dizzys are totally different from the L series

3/ #15040-N8500... Z20S (4 plug distributors) A10 and early S110* The distributor will fit an L20B.

 

* This is the four plug matchbox used of federal Z20E 200sx. This matchbox will fit the L20B so the spindle should be almost the same. Possibly the gear is rotated slightly because the matchbox does not face the front like the L20B ones when fitted to the 11.28 clocked spindle. I think the N8500 spindle will interchange with the 21001 spindle but may have to be clocked differently to turn the matchbox away from the thermostat housing. .

Thanks again guys, as always I'm worried for nothing. I just knew that the L18 had a shorter deck height than the L20 and didn't know where the difference was. Since the difference comes from the cylinder length and not the bottom of the block, it seems like I'll be able to re use most of the little bits from the bottom end to go into the L20 block.
