The dyno graph explains the importance of rpm and its relationship with acceleration.

THIS thread explains the importance of torque multiplication and its relationship with acceleration.

As you are a DD with some 1/4 mile use, I would recommend changing your 1st, 3rd and 4th along with the 4.928 FD. You do not need to change your 2nd gear.

If you want a compromise between rpm and acceleration in 5th gear, may I suggest the 1.000 ratio? This will lessen the rpm drop between the 4th-5th upshift and offer a slight improvement in acceleration.

For what I understood b16b would only need to change its FD right? since 1st, 2nd and 3rd gear are identical to ITR DC2 and since 4th and 5th gear are "larger" the torque to the ground (following the math) would be superior than ITR DC2 and you won't be sacrificing the final top speed, right?

If you installed the 4.785 Final Drive, your 1st/2nd/3rd would be the exact same as the ITR, but your 4th/5th would be shorter, therefore the top speed in 4th/5th would be slightly lower (this is the reason why Honda used the longer 4th/5th, in order to retain the higher top speed)

So to put the 4.785 final drive into my ek9 i would have to install a different first gear also?

If you were to use the OEM 4.785 yes. If you were to purchase our final drive - you would not need to.
