what parts do I need?

do I need the ring gear and the countershaft?

 

yep you need the countershaft aswell as far as i know... what final drive were you thinking of getting?

 

I found a guy selling a rsx-s 05 final drive but it´s just the ring gear. that´s why I was asking. So that won´t help me at all

 

Um, we have the same final drive as the 05 RSX-S (which is the same as the K20 ITR) @ 4.764. Just figured I'd save you a ton of time and a bit of cash.

 

I´m not as lucky as you guys I have a 4.388 final drive so a stock tsx final drive would do the trick

 

^ I'm in the same boat

tsx final drive > euro accord final drive

 

If you get a TSX final drive make sure you get a TSX 6th gear as well or highway cruising will become a pretty frenetic experience.

By the way, the 06 Civic Si has the same final drive (and 6th gear) as the TSX and may be significantly cheaper to obtain (though this is probably not the case in Europe I guess). Looks like the Euro-R has the same transmission as the TSX too -- I guess you have a CL9 Accord? Very odd that they use the K24-based Euros would have the other transmission.

 

Just in case your considering it, I'd advise against getting the 5.0 CRV Final Drive. When you add more power, you'll run into some traction issues and your higher gears will be too short for the highway. The TSX 4.7 is better suited for our powerband.

 

The European Accords also use a slightly smaller (205/55-16) tire, which, based on what I'm seeing here, would make their gearing closer to the North American car's. There's a 17" option, and I recall that was also smaller.

 

mine has 225/45 17" as standard. and I am also contemplating on keeping my final drive and just upgrading the gears 2.3 and 4 (maybe5 hardly see the point for racing reasons, never go there

 

Where would you get shorter 2/3/4 gears?

 

CTR, ITR, Euro-R, 06si and RSX-S

 

I just noticed something else about the gear ratios, my 1st is shorter then yours at 3.533 vs your 3.266.
so that means my 1st is shorter then yours right, but sorta equals out with the final drive?
and then rest of my gears are same as yours and therefor longer cause of the final drive?

 

^ yep thats it for first gear at least it should be similar. in second gear though its a different story. Our cars will reach 100km/hr in second whereas the tsx will reach less due to the final drive.


Also, i think the tsx comes standard with 215/50/R17 compared to the 45 series 17" wheel you have, which means less rolling diametre.

 

I seem to get just over 100km/h in 2nd. somewhere in the 100-105km range.
If we were to swap the final drives,It should be quick off the line with our 1st gear ratios.
but it would be prone to a lot of wheelspin. slicks and off we go

 

lol i like the way you think
