Not 25hp VW. Rings should be 3+3+5 mm and the pins 20mm.

Maybe an industrial engine.

Look inside the piston for a VW stamp there. If none, these might be for another period German car, like Opel.

Are they Mahle, Kolbenschmitt (K over S logo), or something else?

Even if these are a VW size, the ring sizes may not be suitable, and the pistons might be quite a bit heavier. You could weigh one and compare to factory weight ranges given in the VW service manual.

25hp industrial is the same engine as 25hp car engine. Carb jets and eng nr are the only differences.

Besides Std piston sizes are 74,95, 6 and 7mm.

Most probably some Audi pistons for small water cooled engine.

the piston has diferent rings but if the size ad measurement same with 25hp piston, I reckon I can use it for 25 hp engine??

Save the trouble and measure the piston pin diameter. Those look like 22mm and if such they will not fit.

Also the distance from the top of the piston to the pin looks different than in 25hp pistons. I think your's are the same as in this ad. Just a bit dustier.

do you have more details what vw/audi engine they from?

surfindo Wed Nov 12, 2008 1:24 pm

after do google search its probably Motor this what i found:
Fabrikant Volkswagen
Type S-4
SOHC
8 Totale kleppen
2 kleppen per cilinder
Aantal nokkenas lagers 5
Constructie
Boring × Slag 75.00mm × 59.00mm
so they probably from early water cooled vw some golf/polo come with 75'piston
