Yeah.. but i think that's only some preservative paint stuff.. you mean the green on one of the ring's on the right piston.. should be no problem. After cleaning with some solvent these will be metall color i think?

If the oil ring and top ring are different then it looks like somebody made a mixed set.  Rings need to match the hone in the bore.  I think that the green might be more than just paint.  

Makes you wonder about the pistons too.  Have you confirmed that they're all the same size?  What is this special styrofoam box?

Interesting puzzle.  Somebody could buy them and put a new ring set on.  If they can find a new ring set.

Yeah, they have the precise size on them and all 6 are the same 1mm oversize.   the styrofoam box is nothing special, just a box that keeps moist out as there are a lot of inner engine parts in the box. I sprayed the parts with WD40 to keep them away from moist.

I don't think it's a problem to use these 6 in a engine. the one with the green ring is just a newer type i think. If i ever gonna use them i first have a talk about these pistons with a machinist, the cylinders have to be bored/honed anyway.

Used these doglegs on my car, don’t know where they came from as they were in the parts that came with the car. 

I think that there are people now in Denmark that feel a bit ashamed.. when i look how that part needs a lot more attension. (left edge is terrable..)

But yeah, one does not have to start from plain flat steel sheet!

Eh.. europarts? denmark? 

Brand new IN the original packing, A high pressure oilpump for any L20-L24-L26-L28 engine. (Used for special engines that have a turbo for example.)

Part Nr:  15010-A1110

High pressure, or high volume?

It says high pressure.. and if i search the number it says: Nissan high pressure pump for special engines.. (whatever that is!)

But i think it's a pump that gives more volume per min-1.  So it can lube the engine AND something else as well.. like a turbo.

So, finally time to make some pic's of something in my cellar.. I think this is a special part to run a 4 barrel carb of american cars on a 240z? can someone tell me what the round thing is?? (Does that fit ON the carb and go's to the airfilter???)

It's all new parts and was part of a complete datsun z sale long ago..

Lookes like it will fit directly to the inlet manyfold normally used for the hitachi carb's. 

A question would be.. where are those 4 big threaded holes in the square block for?

This looks similar to what you have. Forced induction. You can see the plumbing running from the exhaust in front of the rad (intercooler) and all the way around to the carb.

 

Thanks for the picture!  Is this just a pic found on the internet or from a member on this site?  Would like to see what kind of turbo he has installed there. 

I wonder also what those (fuel?) lines are on the air intake tube? Injection? (seen left of the gauge)

I was going through some pictures on worker B website and thought of you.

Possibly nitrous oxide (NOS).

Also possibly water vapor injection.

 

As your parts are "not often seen parts" @HS30-H you can put them also in this topic.. 😉
