Hi, has anyone got any 25hp barrels and pistons or just the barrels or pistons on their own??

Thanks!

Hi Barclay.

Good luck in your search. They are getting incredibly hard to find- it took me about 2 months to find an NOS set last year. One alternative which I will probably use in the future is to use early Polo barrels and pistons. Apparently 1978-81 Polo/Derby barrels and pistons are perfect for the job and they're available and cheap. I haven't researched this extensively yet, but it may be worth you doing a search on thesamba etc.

Good luck.
Rich.

Hi Rich,

Thanks - I managed to pick up a set of NOS pistons, so I just need the barrels now.

I have heard of this polo thing before, but not spoken to anyone who has actually done it.

There is a company who can custom-make barrels to your spec, so I'll look into this and let peeps know!

Cheers, Barclay.

Hi Everyone,

I know of someone who has very successfully used Polo pistons and barrels on a 25hp engine. Apparently it increses the capacity of then engine by a mighty two-and-a-half horsepower due to slight difference in the design of the top of the piston.

Following this tip off, I used Polo pistons on a 25hp engine I had. I never ran it, but the person I sold it to, said it went very well. All I had done was to have the barrels stoned very lightly, and everything went together like a dream

It's a useful alternative to hunting for either NOS ones, or uncertain second hand items. Best of all, you're still using VW parts!

Thanks - the only thing is do the polo's have a conventional 'barrel' like the ones we are used to?? I thought it was a different design altogether?

Dont understand this a Polo has an engine block polo pistons may fit the barrles or can you get polo sleaves and bore the barrles to fit the sleves and then the Polo Pistons?

Yeah I'm with Andy on this, the polo pistons may fit but polos dont have barrels with cooling fins, just a normal watercooled head ??

I'm interested to see if the polo pistons fit the 25 Hp barrels though if anyone has some details. I will buy a set or two if they are any good :thumbup:

Cheers
Kev

Could larer barrles be used and a stepped sleve fitted ???????????



Andy W

Sorry, yes, my mistake, Polo PISTONS only :oops:

:omg: :omg: :omg:

and its the pistons that I just bought too......

I did find another NOS set complete, but I'm not paying 1000 euros!!!

Might get a set of polo pistons as spares then

Well the saga is finally over..... I got my NOS barrels sorted.

Ursula Hagen lists them as complete kits for 600 euros
BUT
They are an exchange item and you must return 4 barrels and pistons and the barrels must not have any broken fins - unlikely!!! I didn't get mine from here - just thought it useful information for future reference.

So I've ended up with NOS barrels and pistons for about £650 which I don't think is too bad

Might come in as a spare.....
