unfortunatly you cant have acceleration and top speed.
i am not too clued up on the vauxhalls atm but from wat i can gather there are 2 varient of the f15 and f13 being the cr(close ratio) and wr i think (longer ratios).
with the x16xe i would think one of the f15 would be best suited. hope this helps .

Either will suit, the F number is the power rating when you multiply it by 10.
F13 will handle 130ft/lb and F15 is 150ft/lb.
The ratio is your main concern but you can have either better acceleration with a CR or more top end with a WR assuming you've enough power to get there.
If you're running standard power then the only real benefit of WR is better fuel economy at motorway speeds as you'll be doing less revs.
