I swapped a 1.6L into my sammi, and I was able to use the same computer and intake like you stated, but mine is a 91' so it had the trottle body intake on there already so it mad it easier. As far as i'm concerned I don't know how much, if any power I lost, But it still blows the doors off of a 1.3L. You will also need the tranny adapter, And modified motor mount, Then your ready to Make It Hert!
