RS Motorsport :: Classic Speed Restored

Hi Knowledgeable people,
I have a few questions if anyone would care to answer. I read in say the Burton Catalogue in the piston listing 2wd pistons and 4wd pistons for the YB what's the difference between them. Also combuston chamber CCs of an unmolested YB head. The reason is if these pistons would be usable in a force induction 2.0l Pinto and be able to have around 8 to 1 compression and there are lots of fo the shelf pitons available so as not to have to get custom made.

Darrin,

4wd heads are 48.5cc, 2wd slightly more but I've never measured one.

2wd vs 4wd piston, AFAIK, slightly different dish volume to counter head volume difference.

I think the 2wd head is 50cc factory.

Hi,
Thank you for the information that confirms that turbo YB pistons will do the job that I want them too. Thanks
