In order to overbore a pinto up to 2.1 am i right in thinking the bore would be enlarged to fit 93 mill pistons, i.e. cosworth V6 items.
Sorry for indirect retroness of this question.
fankooo

A proper 2.1 uses, 2.8 capri pistons I think. A lot of of 2.1 overbores actually give around 2053cc or something like that

If you look in the current retro mag they have a feature on the pinto and I'm sure they say 2.8 V6 pistons in there. That's assuming the reporters got it right. I haven't bought it for a while turning to PPC instead so don't know how reliable it is.

suppose the easiest way is to just match up the bore to the pistons.

just to throw a spanner in the works, i thought they used 3 litre pistons to overbore to 2.1? could have just made that up though. ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)

Yeah go ahead JC, i don't think hotwire has any hitler-esque tendencies of stiffling free speech.
p.s. i thought the 2.9 and 2.8 both share 93/93.03 size bores. Vis a vis it wouldn't matter.

There was an article in Classic Ford (I think) many moons ago and it gave a list of all different overbore sizes and there were something like 3 or 4 different ways to make a 2.1 from round about 2035 cc upto pretty much bang on 2.1 and I think a genuine 2.1 (with 2.8 pistons) gave a 7bhp gain from standard with no other mods.

www.network54.com/Forum/67242 it's the capri laser page, archaic forum but some very clever (well compared to me anyway) guys on there. The guy with the 2.1 was in classic ford a while ago with it i think.
