Cool, in that case you should look for a gearbox with the 4.266 final drive:
U2Q7 - Accord Type-R short ratio in 2nd & 3rd with Torsen diff
M2P4 - UK 99+ Prelude short ratio in 2nd & 3rd with open diff
M2B4 - JDM 4th gen "standard" ratios with viscous LSD
M2A4 - JDM 4th gen "standard" ratios with open diff

If you use a 4th gen gearbox I think you will need the VSS unit form a 5th gen gearbox to make it work in your 5th gen. There is a difference in the casting of 4th and 5th gen boxes (as in the way they mate up to the block and oil sumps of the 4th and 5th gens). later I can go into this more. A bit pressed for time ATM.
