Cons of longer gears - people will tell you that you will "stay in boost longer", but that only by the butt dyno, when your acceleration is slower to get to desired speed

Cons of shorter gears - good acceleration, higher rpm speed at highway driving speeds car goes more quickly into engine load. This means more use of fuel and even less economy than what you had.

Pros of shorter gears - good acceleration, good for street use to get to speed more quickly. It makes a 1.8 litre act like a 2.5 litre in acceleration rate

Pros of longer gearing - Bonneville speedway top end over 168 miles/hr. (not like you'll ever see it)
I agree. But, if you are making a good bit of power you also don't want that short of gearing because traction may become more of an issue. He also said he was dailying it. I would prefer (not saying it's best by any means) longer gearing when boosted especially for daily. With stock head, he can't rev (well, he can but wouldn't advise. lol) to an extremely high rpm so that takes away some from the time in boost. Also, depends on the size of turbo. If you have a smaller turbo it will fall on it's face on the top end so shorter gearing would be beneficial, but with a bigger turbo the longer gearing would be nice for spooling. Also, it depends on if the motor is built of not. But, for the op. His HP goals are easy to reach on a stock motor with a .57 trim at around 9lbs. Sleeves are good to around 350, I've been told.
