They were not 140bhp, the 20XE's (coscast head) were 156bhp and the C20XE (standard with cat) were 150bhp. I had a modded 20XE in a corsa and it was pretty quick and very torquey. Only weakness was the piece of shit corsa it was in. They are very goid engines though can take loads of punishment not to mention some of them are over 20 years old and still going strong.
