I want to build a 78mm (alternatively a 78.5 or 79mm) bore A15 for road and minor competition use.

What piston do I use?

Thanx all in advance.

I just had a drive in the 89mm (Stew. McKenzie) Clubman.

This jigger has some real grunt. It might look a bit rough, but its light and has a healthy A14. I reckon it accelerates much harder than the XY GT Falcon that I had.

I am definitely going to build one myself.

Hi All

I'm a newby with an interest in all things with cars powered by A series engines and mechanicals.

I'm thinking of building a Datto A12 or A14 powered Clubman.

Has anyone got any ideas

I'm in Melgourne, Oz.
