It seems as if the world has sold out of pistons and liners, apparently most stock were withdrawn with a fault, and delivery hasnt started yet, And yes right when i need a set...
Ive tried most of the big dealers, anyone have any ideas, where else, im located in the UK.

Thanks

Bertelsbeck in Germany has them listed, you could also try OKP or one of the Italian dealers like Epocacar, Autoricambi Sassi, etc. CPS might be an option if you feel like treating yourself to a forged set. In this case, your old liners could be bored out to 80.5mm and moderately oversized pistons fitted.

Although buying and installing standard pistons and cylinders is the easiest way to go, it's only just a little more time consuming to have pistons made and your cylinders bored to fit. I personally like Venolia very much, and they have made pistons for pretty much every Alfa out there. Sometimes they will supply from their standard list, and sometimes they want your piston to copy. I'd imagine they could provide 1750 pistons in any oversize, and with a range of compression ratio choices. The rings they provide will be better than the stock Borgos with the standard cylinder/piston kit as well.

The hardest part is finding a shop that can and will do a good job of boring or grinding out your cylinders. Not impossible, just not as commonly available as other machine shop services.

Anecdotal wisdom is that used cylinders are better than new ones, having been heat cycled to the point they have taken their final shape. Thus, when re-bored they stay more true and less prone to cracks than new cylinders.

I recently dismantled a 1750 engine and was surprised to find practically new pistons. Except for a little carbon on top, you would think they were just off the shelf. I haven't measured the liners, but suspect they were recently replaced as well.

So.........if you can't find new ones, I'm sure I could save you a lot of money with these! This motor will be going into a race car with Cosworth pistons and a different set of liners.

I was talking to a well known and respected Alfa engine chap in the UK today, he was telling me that Borgo have stopped production and have sold the tooling to A N Other Italian company, who have not yet, to date begun production. The concesus among the the Alfa parts retailers being that it could be as long as 6 months before they become available again, although even this is a guess. He wasn't aware of any quality/defect issues.

I have a NIB set of AE Borgo 1750 pistons and liners I could let go. Shipping to the UK would be a killer though.
