WTB: Z20E 152.5mm rods

Postby anguso » 07 Aug 2017 11:03

Hi Realm,
I'm planning a LZ22 long rod motor, and all that remains on my shopping list is rods and pistons.
Anyone have a set of long (152.5mm, p/n 12100 N8500) rods in good shape that they'd like to part with?
Let me know what you've got and what you'd like for them.
Thanks,
Angus

No such animal without custom pistons with about a 30mm pin height and 87mm bore.


152.5mm rods are found on all Z20E or Z20S engines...

'80-'82 HL510 in the States or the '81-'82 HL510 in Canada
'80-'81 S110 200sx
'84-'86.5 720 with the mileage option Z20S engine.

Thanks Mike,
I slipped up - it's the long rod 2.1 that I'm looking to build.
I have the Z22 block, the L20B crank and front cover etc, and am looking for the Z20E rods and the Z22E pistons (preferably in a +1 overbore).
I haven't started a build thread for the engine yet, as it's too soon, but am I barking up the right tree with my shopping list?
From my extensive reading and re-reading of all the threads, I hope I'm on the right track.

Long rod Z22s are 149.5mm and exclusively found on the S110 200sx from Jan. '82 and on, till the end of the S110 production.

The Nissan part number for the 1mm oversize (late) piston is... 12010-D8103

Looks like the rings fit either early or late Z22 piston so 1mm oversize Z22 rings are 12038-06W20

You can use these numbers to cross reference to another brand. If over boring to a clean straight honed cylinder you can go with chrome rings.
