Car: 1999 Honda Civic Si

My plans are to swap in an Integra P/S rack and EG / DC subframe. I've searched but there isn't a whole lot of good information on this. The car has P/S currently and a B-Series motor. I want to make sure that first off the swap will work and second that I have the correct parts list.

From what I understand:

EG / DC Front Lower Control Arms (the Si ones won't work?)
EG / DC Compliance Bushings
ANY EG / DC Subframe (that has P/S)
The Rack Itself

Is this correct? Also, will the front geometry be off in any non-alignment correctable way?

Thanks.

You'll Also need a 5 speed DC rear T-bracket.

Thanks. I guess that pretty much settles it, there's only a couple questions:

1) Can I use an ITR rear mount (rubber)?
2) Do I need the front LCA's or will the "EK" ones work?

You can run the SI lca's, you will just need to run the eg/dc compliance bushing, and all hardware.

Thanks, so a final checklist would be:

EG / DC Compliance Bushings w/hardware
ANY EG / DC Subframe (that has P/S)
DC Rear T Bracket
The Rack Itself

?

Sence your going to be in there, rack bushings, tie rods would be a thing.

It will be so much easier now, than down the road when its in the car.

But your list looks fine to me.

Just came into my head, what about the ps lines?
Are they the same?

I've actually recently replaced both the tie rods and upgraded to the stiffer ITR rack bushings. This was before I knew I'd be swapping racks, but either way it's already done and it's one less thing to do.

That was my last question too was the lines? I could've sworn they are at a different angle on that valve?

94EG8

Nope, and uh, neither is the pump. You'll need a '92 - '95 Civic P/S pump bracket and a '92 - '95 Civic or '94 - '97 Integra P/S pump (both are the same) All lines need to come from a '94 - '97 Integra, so does the reservoir (I found this out the hard way when I swapped an Integra rack into a '93 Si) Ideally get the subframe from a DC Integra, '92 - '95 Civic is basically the same, but the Integra has a nice stiffening bar (the bar will bolt on to civic subframe though, the holes are there for it.

Also, yes you can use an ITR rear rubber mount.

Wow, all of that is needed? That makes me second think the swap.

Might a bit more involved than I wanted.

What is the advantage or point of this OP? Just wondering what all the trouble is for.

I want the quicker ratio of the Integra rack. I know that people that are swapping the Integra internals (the pinion gear to be specific) in the EK rack, however it's been made known that the splines are thinner on the DC internals and that this would cause pre-mature wear overtime. The other option is to swap the pinion gear AND internal rack of the Integra, but the one guy that did that said it caused a negative impact on his turning radius (something came up shorter?)

This seemed to be the best method with no issues, but may be way too involved after all.

I understand. You must track your car?

Swapping subframes/racks is a pain in the *** w/o a lift. Ask me how I know. At least it's not as heavy as it looks.

sk8shorty012

I work @ at a Honda dealer so I'm not concerned about a lift / tools / labor. It's just if there are THAT many parts to change it's not worth it IMO.

I daily the car.

From research it seems as those the low pressure line will work, but I need to find a high pressure hose. Is there a high pressure hose that fits a 99-00 Si P/S Pump and works with the conversion?

I suppose I could just loop the P/S but I want to make sure there's a line that would work in case I end up selling the car (I'd hate to have to swap racks back just to gain P/S).

94EG8

Integra rack is quicker steering from lock to lock.

IIRC the integra rack wont turn as tight. I really never took much note before and after. It is definitely quicker though.

Didn't realize this was an Si. '98 - '01 Integra lines should work with an Si P/S pump. If it's anything like the '92 - '95 Civics you'll need to change the return lines and reservoir as well.

The return is a softline so I should just be able to cut a hose to length. If the high pressure hose is all I need to add to the list then I'll probably still consider it.

Would you say it's worth it knowing what I'm about to put into it parts / cost wise?

94EG8

There's more to it than that. There's a hardline as well. The '92 - '95 Civics had 3 lines really, the integra only had two and a much smaller cooler (if you could even call it that) it also had a different reservoir (2 ports instead of 3) but i'm not sure how the '96 - '00 Civics are setup.

If you're tracking the car probably. It's definitely quicker, Like I said I swapped mine but I haven't driven the car on the road since, just around the yard so it's hard to make a good comparison.

i got a 95 integra gsr and my buddy has 2000 si and i didnt really notice the difference in the steering rack

sk8shorty012

I still think I'm going to go for it. It's ridiculous, the EK has absolutely the worst steering rack / ratio compared to most all Hondas. The Del Sol, EG, EP3, RSX, CR-X etc ALL have better ratios.

I need to figure out the lines though?

sk8shorty012

iTrader: (3)

any input on the lines?

sk8shorty012

iTrader: (3)

I figured out the lines, I'll use the Integra high pressure and just use a rubber hose (custom) for the return line.

I'm ordering misc. bolts and whatnot for the swap and my question is for the FLCA do I need both washers for the compliance bushing in this pic?



The EK FLCA arms that I'm using only use one washer on the rear side, do I need to order the front ones since I'm using the EG / DC compliance bushings?

sk8shorty012

iTrader: (3)

anyone know? This makes me think that maybe the EK FLCA are not compatible with the same (after some additional research too).

not sure why u wanna do this... but whatever you guys said...

It has been stated previously that the DC power steering racks have a much quicker ratio than the EK.

cdeluise

This is good info. EK's steering ratio is horrible!
