the stage 2 plus will be fine in a 1.6 cvh running that power

as the cvh dont make big lb/ft

but be warned they make the car very twitchy as the car will pull from side to side quite violently due to the atb diff that is fitted in the box when driving hard on un even roads

it gets some getting used to i can tell you that

and as for the comment on better off with a standard box

that would last all of 5 mins lol
