Sorry if this has been covered, but I already did a search and got nothing.

I'd like to see gearing charts for the DC5 Type R vs. the Type S.

 

Go to honda.jp and you can find the gearing charts for the type R. Im pretty sure there the same except 6th gear. Go to acura.com for the type S.

 

Well the final drives are different, correct?

The Type R is a 4.76 while the Type S is a 4.400, right?

 

the dc5-r has the 4.764 final drive, the usdm rsx-s has a 4.38 or something like that.

the 4,5,6 gearset on the jdm trannies are also shorter, mainly 4 & 5

the 1,2,3 gears are the same

 

Yup, 4, 5, 6 and the final drive are all different (and better) than the USDM trannies.

 

.....and what about the final drive + gearing of the usdm ep3 si?

 

I think final drive for the EP is 4.76 like the R

usdm ep3 has a 4.764 final drive, 4 & 5 are the same as 5 & 6 on the type-s tranny.

1,2,3 are all longer.

Regarding final drive swaps, how would you put a USDM EP FD into an RS-C tranny if one is a 5 speed and the other is a 6 speed?

The countershaft usually houses 1/2 of the gears in the tranny (ay least they do in the B series, sure they do in the K too) so that would make me wonder if the 5-speed countershaft would support the 6 gears of the Type S tranny.

Also regarding the JDM DC5-R 4.7FD - I think chunky told me that it supposedly is not a direct bolt in.

Is it a simple matter of the first gear not being the same size like the B series JDM 4.78 vs. the USDM 4.400 trannies? If so then the FD set *should* come with the JDM R 1st gear, distance collar, etc. as well as the 4.7 ring gear and pinion (counter) shaft to make it work.

Also is the CTR tranny the same as the DC5-R, or not? I'd bet it's pretty much a Type S tranny with O.E LSD, right?

 

dc5r and ctr are the same trannies.. correct me if im wrong.. dont the crt and dc5r have the same engine and tranny??

No.

The CTR has the same engine as the RS-X Type S. It's rated at the same 200hp and everything.

The DC5-R is the only car with the 220hp K20A.

I think the CTR probably doesn't have the same tranny as the ITR (DC5-R) because the DC2 ITR and the EK9 did not share trannies either - the ITR had the 4.78FD after 1998, while the EK9 CTR never got the 4.78FD.

 

Good questions hopefully someone will respond with some real answers.

 

ummm no! the uk CTR comes witht the USDM RSX-S motor but the JDM CTR has a 216 hp with the same tranny as the JDM type-r. correct me if im wrong but the spoon CTR rips the spoon RSX-R a new *** on the spoon video that i have!

(think the CTR probably doesn't have the same tranny as the ITR (DC5-R) because the DC2 ITR and the EK9 did not share trannies either - the ITR had the 4.78FD after 1998, while the EK9 CTR never got the 4.78FD.)

but also remember that the old R's did not share the same motors ex:16a and 18c or whatever the codes were!

you make me question the engines because i do recall someone posting something similar about the EP3-R engines. But I am rather sure that the EP3-R has a K20A2 rated at 200HP ( i dont even think its HP, rather PS or something along those lines ) as for the trannies im not sure of at all.

If the K20A2 goes in the EP3-R I wouldn't doubt that the type-S and the Ep3-R have the same gearing.

As for that spoon video comment, i haven't seen it for myself, but isnt the DC5 just slightly lighter than the Ep3? stronger engine, better gearing.

Tom, your finally going to go for the K20A? Best of luck on the swap. and personally, if you are debating between the A and the A2, think of it in terms of B18C VS B18c5. you wrote a fat post on that. and reasons why the C5 costs what it does. I know its not quite the same situation, as there are major differences. But its still the same general idea.

and slightly OT: i know the k20a3 only has vtec/VTC on the intake cam, but what about the type s and the type R? i know the type S has VTEC on both intake and exhaust cam, but does it have VTC on the exhaust cam? or is the K20A the only engine that has i-VTEC on the intake and exhaust cam?

I heard the same exact thing. JDM EP3-R and DC5-R both share the same 220ps K20A motor. The UK EP3-R has the K20A2 in it.

Edit: Actually, it says it in the best motoring international video vol.3.

I wouldn't be surprised if the ep3 transmission could support a 6th gear. The way I hear it, you use the ep3 FD, collars, bearings and countershaft. If you use the JDM one, you need to get other bearings & collars to prevent excessive play between the gear teeth.

I know the UKDM ctr gets the same engine & drivetrain as the usdm rsx-s, but the JDM i know has the r transmission, not sure if they bumped the power output though.

 

or you can use a Tsx final drive that comes in at like 4.760 Fd that goes directly into the tranny with out any mods just like the B-series Fd swap

yeah that's what i said before

 

Is it possible to JUST swap the RSXS tranny into the EP?
