Here is a table I put together of all the transmission gear ratios in all the cars I could find published data for.
If anyone finds published data on the CTR please let me know so I can add it to the chart.

If anyone has the tranny codes of the engines listed below, please let me know so that I can add that info to the table. Please be model specific with the tranny codes so that we can see if some models use the same exact tranny etc.

All my info is from honda.co.jp, acura.com, new-cars.com.

I noticed Acura.com rounds up when i compared to ratios found on honda.co.jp. (Example: 1st gear is 3.27 instead of 3.266.)

Tranny notes i have put together:
1) 01-06 accord euro-r and 05-06 rsx-s have same tranny.​
2) 01-06 itr has the same 1-3 gear ratios as the 02-06 rsx-s, euro-r, and 06 si but has different 4-6 gear ratios.​
3) K20A2, K20A euro-r, K20Z1 all have the same 1-6 gear ratios.​
4) all 6-speed tranny's except 02-04 rsx-s & 06+ CTR, have the same 4.764 FD.​
5) 06 si and 04-06 tsx have same 6th gear.​

don't forget about the LSD...

Other than that great little list you put together there. I'm surprised the Euro R has such short gearing...

I can't wait to get my TSX tranny in my car so I can see how big of a difference the longer gearing makes. :cool:

Good call, i can totally add the LSD option right under the the Final Drive listing.
Also, the Euro R has a K20A, that is why it has the shorter gearing. It does not have a K24.

Yah but you rememebr the other day that thread with the tranny and the different mounting points? Thats cause it was teh Euro R tranny, teh guy said it had an LSD because he could see through the diff.

and I only comment about the short gearing because the euro R is based on the TSX chassis. So i figured they would be longer for the heavier car... I guess the gears are based more on the powerplant than the chassis.

The thing I am curious about is that the auto vs 6 speed models.

From what I know from b series the auto models always had different cams, but don't know about the tsx auto vs manual.

will they yeld same results power wise or will the manual put down more power..

everyone that got swaps from the train wreck were mostly auto version cars

These are the posts that Gods are made from. You guys remember all the original pics of obd and vtec wiring from FF squad? Well in 10 years when K series is as mature as B series are now and n00bs are asking about gear ratios, we'll be able to post Jalal's OG data. LOL.

Until we have physical proof of a picture, or literature proving that the Euro-R Accord tranny has an LSD, i am going to consider it not to have an LSD.
The Honda Japan website does not list the Euro-R having an LSD ANYWHERE. It does however list the ITR having an LSD.
Updated table is posted.

6th gear on the new Si looks like it is going to be a cruising gear and not a beneficial gear for passing and/or speed. Whereas on my tranny, 6th gear pulls hard still. :)

Nice list Jalal.

hahahaha sorry man. Just haven't been on MSN when I go home from work, just hate looking at the computer when I do it all day long at work. Can't get on MSN at work anymore, we put up a new security suite and it killed it. I'll shoot you an email or get online later tonight.
OK cool.
Anything new with the car? How has it been?

Nothing really new. Was going to have the Mugen tranny cooler installed while I was in the states, but I completely forgot about the air condenser. Stupid me. I can lose the A/C for myself, but the gf might not be too happy. Guess we could always just drive around in her car. :D I am going to contact Mugen and see if the a/c condenser has to go or not. I might be able to fabricate a mount for the tranny cooler to place in front of the condenser. I sheared my Motul Gear300 oil after only 2 gymkana events. I knew alot of race teams are using the tranny cooler over here, but didn't think I was really going to need it as I am unable to do any circuit running. I guess though, gymkana may actually put more stress on the tranny with constant shifts between 1st and 2nd, the heat builds up quickly.

The car is running really well. It's even louder now...my Amuse exhaust blew a chunk inside the canister, I was playing around with some GT-R late one night and at about 195km/h I started seeing sparks and flames in my rearview mirror. Pulled over, looked at my exhaust and inside was a hole. So now the inner material is making its way out and the car is just WAY TOO PHUCKIN' loud now, but I LOVE IT!!! hahahaha

Thats some crazy shit Chris. What happened between you and the GT-R???
Keep us updated on the Mugen Tranny cooler. I know you want to tranny college because you do alot of gymkama, but do you think that will help with the grinds and shit that we experience during regular driving? Or is temperature not really the cause of that problem?
