Need some Info on these pistons & rings

[jakeoster]

An old school acquaintance of mine who has never used a computer asked me to try and sell a brand new set of pistons and rings for an L28 thats hes had sitting around for many years. Problem is Ive looked around the internet and searched HBZ and cant get any info on them. Nothing even shows up on HBZ about them.

 

 

 

 

 

 

 

Thanks in advance.

They're just regular cast aluminum pistons. Find out the diameter of the piston and obviously thats your bore. If its 89-90mm then its probably a KA24DE piston, should have a dish of 2.8CC I think. L28 pistons should be like 86mm stock and then probably up to 88mm oversized. Dish volume for those would be 10.9cc.

 

Clearly the label says L28 and then it says .50 so that's probably in millimeters, thus 86.5mm bore and as stated 10.9cc dish according to this:

Like I said, regular cast pistons, you can see the casting marks on the side around the pin. It looks like a grid. My ebay KA24DE pistons that I bought for my motor came in the same NPR box and rings packaged the same. I got them for $60 for a set a 4, had to buy 2 sets. Here are mine after the pins were pressed in, you can see the box in the background:

They are 86.00mm. Look at the box. Says it on the side. Just stock L28 pistons with rings. Great for a freshen though.
