There is another company to offer a TR6 piston.

It is Nüral, a well noted supplier of car industry.

Would prefer this one.

 

But as I had perfect results with the VW piston

this is my recommended way to go.

It is lighter, stronger, cheaper and has a skirt coating

for reduced friction.

Being stronger results from hypereutectic material that

allows to reduce play in the bore by 50%.

 

For the wilder ones I would recommend the MAZDA piston,

being a very similar copy of the TR6 but stronger made from

hypereutectic material and larger up to 78mm for a big bore TR6.

Also a wonderfull piston but a bit more work to make it fit.

Andreas,

 

Could you please tell me if the TR6 Nüral piston needs any modification, or is it a straight replacement?

Hi Allan the original Nüral TR6 pistons look

great and fit right out of the box.

Andreas,

 

Thank you.

I looked at the TR6 Nural pistons and asked my local motor factor to get a price? I was quoted £109 each? So also after being told by 2 engine m/c shops that they had never had a problem with county pistons but they always check them carefully and weight them. This is what I went for in the end.

Crazy!!!!

 

After a short check I found this:

These pistons are 50 Euros what is about 42 GBP.

So here you get three of them for that price.

 

The other way round is when I order British parts here in Germany

In most cases its worth to search in GB although shipping is more expensive.
