One set of 6 six L24 OE cast pistons
Yes, aftermarket versions of these pistons are cheap and plentiful.
These are not those
These are the real deal proper Factory parts, and and are priced accordingly
These are the 1973 240Z L24 "popup" pistons with the eyebrow valve reliefs in them
They were made for the open chamber 1973 head, and stick up out of the block about .030"
They can be used with the earlier smaller chamber heads if you want to raise the compression ratio
If you have a performance cam with higher lift and/or more duration, you may need to confirm that valve-to-piston clearance is not too tight, since these pistons were never meant to be used with those heads
If you are going to be running pump gas, you should also do the appropriate math in order to confirm that the compression will not be too high for pump gas
If desired, these pistons can be shaved down so that they will be flush with the top of the block
We can provide contact info for a machine shop in Richmond, VA that has done this mod before
It will reduce the depth of, but will not eliminate, the eyebrows
These pistons will also work in 260Z L26 engines, and even L16 engines if you want to have a couple of spare pistons from this set of 6
The same warnings above for using these pistons with small chamber heads apply to L16's as well
These Genuine Nissan pistons are NLA from Nissan
