I've searched but found opposing information regarding factual #'s on steering rack ratio's.

Currently, I'm using a Manual 92-95 Civic rack but I want to upgrade to something quicker. As we all know, Quaife sells a quick ratio R&P which is set at 3.25 LTL. From what I read, this is a significant "upgrade" over my current setup.

From the information I've gathered on here, the Power Steering racks from 94-01 Integra's including ITR's have an even quicker ratio than the Quaife.

My question is, what are the ratios between the GSR, LS, ITR's? I would assume the ITR has the shortest ratio. A credible source would be appreciated. I have a chance to purchase a 98 ITR rack but the price tag is high, so I may just get a GSR one if there isn't a noticable difference.

 

I read from a credible source on this forum that all Integras have the same steering rack, ITR's are NOT quicker even though some brochures say differently.

I drive an Integra for daily/autox/track, and can not stand the slow manual steering rack on EG Civics, especially for autocross!
I've also driven an Integra with the stock rack but the PS disconnected (due to a K20 swap), and it was good to note that the extra effort wasn't a big hindrance for autocross.

 

I've read that, but I've also read different. There is alot of contradicting information here so I wanted to see if anyone can provide some proof that support their findings, such as a credible source. Thanks for your input

 

the ITR's could have different knuckles with shorter steering arms that would affect the steering.

i dunno if thats true. you could look up the part numbers.

 

Same part no., same rack. Plus they feel exactly the same.

 

then which brochure said anything different?

did they mean just stiffer rack (extra bracing) for "quicker response"?

 

the Knuckles are the same part number.

the steering racks are the same part number

steering rack part# (53601-ST7-A62)

Knuckle R FR part# (51210-SR3-N10)

 

Would you happen to know the ratio/how many turns LTL?

 

No i don't.

 

 

Thanks bud, much appreciated.

 

so 2.98 for an integra rack, and 3.25 for a quaife modified rack.

I have an EG hatch and have wanted to upgrade to fewer turns lock to lock.

From reading this thread, it seems the integra rack is the way to go, especially if I can get it used for cheap.

Now, here is the 65K dollar question. Is it a straight swap? Or does it require modifications of some sort? And what years integra will work?

 

The diameter on PS racks is larger, so you would need a PS subframe, or you would need to modify the mounting bracket. 94-01 integra racks/subframes will work.

 

Okay, that sounds too involved.
I'll prolly opt for the quaife unit then

 

It should be no harder than installing that quaife unit in your current rack, and still a fraction of the price

 

I may be mistaking what a subframe is then.

 

Apparently the pinions are the same in the power steering civic and integra racks, making the actual "speed" that you feel of the rack the same, but the integra has less teeth on the rack so it won't make your steering faster, it will only make your steering radius worse.

I took apart a DC2 rack, removed the PS seals, sealed the hydraulic ports and swapped it into my EG. I didn't like it so I'm going back to a stock EG rack but I'm going to splice a steering quickner into the column and go back to power steering.

 

How do you explain the integra feeling way way way quicker steering wise

 

I didn't notice any huge difference.

 

 

I'm in to find out more about this.

I have an EG6 SiR that comes with p/s. Have a DC2 Type R rack sitting in a friends workshop and always wondered if it would fit and make any difference.

 

I can't remember having any problem aligning anything. The bearing in there basically self aligns the pinion I think. I don't think it's very easy to screw that part up.

 

In my OPINION the number of turns from lock to lock means nothing. What matters more is the gear ratio inside. Some racks are geared quicker (read more efficient) than others, so in effect, overall ratio should be a better indicator of actual performance than the "#of turns lock to lock". That's my $0.02....Anyone else care to chime in on this subject? good luck...

 

Maybe higher tire pressure?
"feeling" quicker and "measuring" quicker would be two different animals entirely. good luck.

 

How were you using this rack though? racing in any way?



I am also very interested into this subject!!! I have a hard time taking hard turns in Autocross's with my hands having to turn the wheel more than once.

If I am running a manual rack would it be better off to get the Quaife setup or an integra setup.

Does the Integra manual rack bolt right up or also needs a sub-frame swap? (Does RS come manual ?? )
