hi. is posable to swap out 4. 5. 6 gears on an sti box for a higher ratio.

You could but I dont really see the point, do you know what they are ratio'd to? its higher than a 5 speed box

I'd leave 4th alone, I'd just go for 5th and 6th
Tho in all honesty, when your out having fun on back roads, even 5th might take a little joy out of it!
6th gear might be enough just to lower revs on national roads and on motorway runs?

personally, I find that there is quite a gap between 4th and 5th. Anyone else? you have to be really going some in 4th before you go to 5th, or else I find you get a bit of lag that you don't see in 1st to 4th...

As said though, it's not often that I am going quick enough to get up in to 5th. 4th will take you to over 100mph...

JDM's still ratio higher than a 5 speed box

Sorry got that **** about face JDM are high ratio!
For info.
I'm at 3500rpm at Motorway speeds in 6th nothing like as high on the old 5 speed.

It's not as simple as just the gear ratio you also have to consider the final drive. I could be wrong though and it could be subjective looking at the top speed calculator...
