Pistons for TR6

Recommended Posts

Hello, somewhere on the forum there was a mention of a VW piston to fit a TR6. It was a 1.4 Polo in 76.5 with a .5mm over-size .I would like a bit more information if possible.Regards,Michael.

I have read about the VW pistons but also the Mazda pistons. They seem to be easier to convert. I have a mechanic who do the more advanced jobs on my engine. He's about 80 years old now and very experienced in (re)building engines. Many of the drivers in the historic racing series here in Sweden goes to this man for advice and maintenance of their engines (which he built in the first place).

He recommended the Mazda +0.50 mm pistons when I commissioned him to build my engine. So we choosed them and they have worked fine so far.

However, if i remember it right, there are some VW parts involved in the build and it is the tubular push rods.

Hello Melmac, The VW pistons seem like a fair bit of work and are expensive here in Australia. So which are the Mazda pistons (part no.? or model ) and an idea of the modifications, please.Thank you.Regards,Michael.

Im pretty sure it's from the Mazda's E3 family. I took a picture of the box to have as reference if I should need more of them. Here you can read more about it > https://en.wikipedia.org/wiki/Mazda_E_engine
