Largest standard capacity was 1712cc. I'm told that Autodelta in 
England do a conversion with 90mm pistons, which gives you 
about 1830cc (1712cc engine has 87mm bore).

Don't know how reliable the 1830cc boxer is.

Hope this helps. There were also some articles in "Cars and
Car Conversions" mag about getting more power from the boxer
engines. Someone scanned some of these and put them on the
net. e-mail me and I will try to find the URL for you.

Some of the guys racing Alfasud's and 33's are getting
160-180bhp from 1.6 and 1.7 boxer engines (non turbo).
