hi,
im about to rebuild my steering rack, and i got some answers in this thread https://honda-tech.com/forums/showth...steering+ratio cant find any difinituve answers on the rack swap, only on the pinion swap. i cant find the thread were someone did the whole thing.

I know it can be done and i want to know what part a needed to swap the DC rack/pinion into the EK steering tube/shell. should i use parts, like seals and bushings, from the ek or DC?

 

anyone ?

i found that the rack is 1'' shorter... cant find anything about the diameter. it would help what seal i need. nobody have a rack laying around?

 

I have one in the garage i need to harvest the pinion out of. If you really want measurement i can take them for your.
The DC/EG racks will not bolt into your EK. They use different mounts etc.
Now you could get the EG/DC subframe and then you can bolt in that subframe with the EG/DC rack.

 

that would be great ! what year , i need one from a 98-01 DC, theyre not the same for 94-97

yeah i know about the subframe swap. also found to swap the DC pinion on the civic rack. seems it is not a perfect swap, the thread pitch (?) on the pinion is different from the one on the rack.

i read somewhere,and talk to the to the guy who wrote about it, that you can swap the DC rack in a civic housing, the rack is 1/2 in shorter.
i looked at parts numbers and the seal kit, bushing and guide are the same number. i probably means it somewhat the same size


thats why i want to have the diameter.

are you swapping the pinion on a civic? if so, what line will you use to connect it? bending the civic ,integra line or new lines?

thanks

 

the 98-01 rack is different from the 94-97? I was unaware of that. I'm not sure what year mine is, i didn't check the junkyard teg i took it out of.
The plan is to take apart the civic rack and the teg rack apart and get measurement for the guts and see if i can swap the internals of the teg into the civic rack. As you pointed out the gearing on the pinion worm gear is cut at a different angles on the two racks. So i had the same though you have. Only thing is i am not planning to use the power portion. I would cut the collar like the Miata and rx7 guys do to de-power their racks and run things like that.

 

iv sent a mail to http://rackdoctor.net/Home_Page.html they can custom build a rack like a want, not very expensive, but i want to do it myself. Now i know it can be done.
thats the plan i have for next spring, the rack and pinion gear from a teg in a civic housing.

again, according to 3 online part dealer site i searched.
I searched for my car (98 civic) and most parts are the same for a 98-00 civic and 98-99 integra. things like the spring and nut holding the rack guide in place are also the same
i am pretty sure it can be done safely.


but cant confirm what inner tie-rod is needed, nor cant on how un-power your powersteering. if all holes are capped and the insides are greased, i see no problems(ill look into that for reference)My problem is to get lines to keep mine powered.

its all speculations from me, cant work my car and get parts in winter, so no confirmation for me until may.

ill have to rely on your findings and thank you for helping me in my search

 

You can hybrid the civic/integra steering rack together and it will plug and play.

as you may have seen, i posted this thread in my first post. the problem as i see it is there are 2 different rack from the civic and at least 2 from the integra, and its not miss and match. some look to be quite the same and others dont. thats a big problem for me, hence the thread

i like it simple, safe and to do it once, so the best match is taking both part that work closely together and keep it like that. the rest is just seals and and lines, less important than the link between me and the road.

 

UPDATE
::See post below for updated measurements::

 

great thanks for your help!

i dont know about manual rack, looks different.
but the length seem to be quite close, about the same answer a got from the other guy, he told me half inch wich is about 2.5cm

for the tie rod end, the civic and integra should have the same length, same part number, even EG have the same part.

i dont know if we can clonclude something about the PS rack O.D.vs the manual. since the lock washer is ''locking'' on the PS rack itself and its the same for 98-00 civic and 98-01 integra, might have the same OD. But the 94-97 teg have the same lock washer as the civic with a manual rack and the same as the power steering 96-00 civic with auto tranny... weird

again, all my deductions are according to parts dealer...

thank you, and if somebody have a civic 98-00 PS rack they can get some mesurements it would be appreciated

 

I have some pictures.
Sorry about the flash. I couldn't get the damn macro function to work for me either.

Civic manual vs integra pinion gears/asymbily: civic at bottom, teg at top.



A shot where I tried to get a good pic of the measurements of the pinions. I wish i knew how to use Photoshop or The Gimp. Maybe then I could clean up the flash and make the ruler numbers more visible....
Civic is on the right side and integra on the left.

I really wish there was some place where I could get racks from at core prices.
I would love to get ahold one 92-96 and a 97-01 Prelude racks and take the apart for measurements. Paying almost $60 for a good rack to just gut for curiosity sake is a bit much.

Wabo, did you know a First Gen CRV rack will bolt right in to an Ek and they have a slightly better steering ratio than the factory EK civic racks.?

 

wow nice work!!

no i didnt know about the crv, but some many parts a alike to the civic. thats one more. im a bit surprised it has a better ratio.

im looking at part-out everywhere to get a rack for cheap also, as i said around here in QC where in covered in snow , not much is appening. i dont want to go at u pull in knee deep snow either...

but you have improved my knowledge of theses parts, thanks a lot

 

are you trying to do a power to manual steering swap? or are you just trying to replace your broken power steering rack and pinion. There are still some companies out there that you can buy re-manufactured oem rack and pinions with a core charge. I did a power to manual swap on my EG.
just like the other guy said. i had to swap the sub frame for a manual sub frame. and also the tie rods were a little different but they still work just fine.
the company i got my re-made steering rack and pinion from is called one6 motorsports

 

thanks for your reply
idont want to have a new rack, mine is perfectly fine. i want to swap a DC rack into a ek housing to have a better steering ratio, and i want it as save as possible since it the only link between me and the road.

i know about the eg/dc subframe swap. i dont want to do to this as i have both EK9/EM1 control arm and sway bar, wich dont work if i swap subframe. Thank you for confim about the tie-rods.

i found a place that will mix and match parts from DC and EK http://rackdoctor.net/Home_Page.html for 215$ not very expensive. But i want to do this myself and Confidence seems to as well. that is why we are doing this thread.

 

just a quick heads up.
I just scored a 2000 Si rack so another rack dissection is coming up hopefully this weekend

 

i have some updates here and i revised some of the numbers. ie: i got a good 25mm micrometer


tie rod lengths:
civic man tie rod ~18.5cm
integra tie rod = ~19.5cm
civic pwr tie rod = ~18.5cm

rack lenght:
civic man rack length ~72.5cm
integra rack length ~70cm
civic pwr rack length ~71.5mm

Outside Diameter of racks:
civic man rack od 23.97mm
integra rack od 23.99mm
civic pwr rack od 23.98mm

pinion asym. height:
civic manual pinion height ~21.5cm
integra pinion height ~21.3cm
civic pwr height ~ 21cm

color code for pics: blue = integra yellow = civic pwr green= civic man

 

allright Wabo I have an answer for your question now.

There is one MAJOR caveat to this information:
The main power steering seal is in a different position on each rack. <u>Your power steering may not work right and could be dangerous to use. Ie: it gets stuck in a left or right turn. </u>
Its a safer bet to de-power the rack. You can see this in the pic where the racks are side by side. The integra's valve seal (not sure what its called) is about 2.5" back from the civics. This means the inlet and outlets no longer line up.

I de-powered my rack by cutting out the main seal. You can see the seal locations on both the teg and the civic in image below:
I am not sure the racks will propperly seal when you do this, I think they will. Like a dumbass i did't measure the seal sizes on the racks before i cut and discarded them...

Yes, you can mix and match the steering parts. If you want have a "frakenrack" built you will need the civic body and valve housing, the integra pinion gear and rack and the integra inner tie rods. The overall length of each rack including the tie rods is 90cm. That's why the integra rack has longer inner tie rods to make it equal out to 90cm. The civic ones will fit but you may wind up with too much toe out using them as they are shorter.
pics:
remove this seal to de-power your rack. This is the same method used by the Miata and RX7 guys to de-power theirs.

 

hahaha that is some research ! awesome

if i get you right , i need to use the body where the hoses are connected from the civic (to keep the original lines?) and the pinion from the integra. in the FSM the said to replace them as a assembly has they are pricision machined parts. the bearing is the same?

 

Keeping the lines may be a moot point. I edited my above post to point out a major safety concern regarding powering the rack!
To answer you questions about the bearing and the valves what I did was swap the units from the civic over the integra pinion gear, thus maintaining the matched set. The bearings are the same.

So in the end it appears the the best option is CRV rack.
Which according to vehix.com has a steering ratio of 17.1 (3.23 turns lock to lock) making it the same ratio as the integra rack and a tad faster than the stock civic power rack @ 17.7 (3.6 turns lock to lock) and most importantly <u>OEM and SAFE</u>

All in all it was a fun experiment and I thank you for motivating me to get off my *** and do it.
Now, if I can find a prelude rack super cheap i'll be back at this again for a potentially faster rack :D

 

nice!
1 more question, i reread the original thread in my first post and theres a person who said that the pinion and the rack fitted perfectly, do you still have your 00 rack available? i know you dont know the year of your DC rack , but could you look into this? are the spline different for the civic rack?

 

which splines are you asking about?

 

the splines for the steering shaft are all the same if thats what you're asking

overall this is a great mod, but it makes parallel parking a bit of a job if you have big sticky tires, a tight lsd, and no power steering haha

 

What was the outcome? Sorry trying to follow reading thru and I got lost somewhere. So, it's gen 1 crv rack with what and what?

 

Thinking of doing this. My DX with power steering removed takes too much rotation to get around corners at speed and doesnt seem very safe for chicane type corner sets. So I've got an ek with power steering removed. All I need is the gear and pinion for a 96-00 integra? Thanks in advance guys.
