Is this a sound plan for a sleeper A55?

- bore out stock intake port to 17.5mm

- custom 17.5mm ID intake PHVA 17.5mm and filter to fit under stock motor covers

- taller gearing for more top end speed

- unlimitted rev CDI box

- expansion chamber pipe

Here are a couple of photos of stock intake and exhaust ports ID's.
