rear hicas to non-hicas swap..whos done it/info/advice pls

[S14Cuhh]

need a subframe swap.. i have a 92 hicas, and i bought a non-hicas subframe to throw in. the frame has all arms and both axle..

also,are their sensors for the rear hicas or anything else to watch out for ?

oh and how long did it take you guys for this job..

anybody with info pls lemme know

[Chrischeezer]

does your new rear subframe have the diff too?

the HICAS diff and non/HICAS diff are different
The HICAS diff is larger in size, and the drive shaft is also shorter.

I went with the HICAS eliminator bar
I installed a LSD (nismo1.5) and had to change the drive shaft to non hicas drive shaft. too... everything bolted right up

not sure if that info helps but... there u go.

[projectRDM]

The HICAS diff is longer because it has ABS.

Removal of the lines is the most tedious part, they run the length of the car. The subframe itself is cake.

so to swap the frame i need a driveshaft?! omggg

my subframe doesnt ahve a diff just 2 axle....aksjh;asfh;sjfh!!!!!

[S14Cuhh]

oh wait, what if im not abs? does that eliminate that issues?

[heiyuu]

This HICAS w/ ABS stuff must be a NA thing cuz my 180sx has hicas but not abs. Although I think I read somewhere that all Canadian 240sx's w/ hicas also have abs, I'm not sure if that applies to you yanks.

I will also be doing the swap from HICAS to non HICAS subframe as I need it to use my SPL arms. My buddy who did it on several 240sx says all you need is the sub frame [keep ur stock axles, vlsd, and stuff] and a non hicas ps pump [I'm assuming to take care of all the extra lines feeds that a hicas unit has]

[Z33dori]

man this make it seem way more work then what i was told

so i need:
NH subframe
Non Hicas PS pump


pull the lines...
put in new frame
new pump

maybe not that much work... i just wanna ditch this garbage shit

If you don't have the diff, stick yours in the new subframe. Easy. That's all you'll need to swap over.

[Devil Man]

holy shit you guys are making my head spin reading all this.

to swap the sub frames is cake i did this exact swap on my car

you will need to get-

non hicas ps pump. (make sure you get a s13 pump)
oil cooler small one really.
non hicus ps resivor
and the hose from the resivor to the ps pump

now what i did with my swap was i just cut the lines at the rear or the sub frame were they are rubber so i could drop my sub frame. i then next removed the cluster fuck thing on the side of the frame rail (pass side) that regulates the rear steering. in doing this you will see why you will need the oil cooler, cause hicus cars ps cooler line is what feeds that rear steering so run the aftermarket cooler from the rack to resivor. take your diff and shit and swap it over DS will be fine since the diff itself is what is longer for the abs sensor in the front of the diff. thats about it really its pretty simple.

[S14Cuhh]

swap is complete..pics soon..need coilovers and rear brake pads.
details to come

[Z33dori]

yes plz do share what all u did, and tips.. i need to get this done before may...

[Devil Man]

why the oil cooler and ps pump..how does that affect me just changing the subframe


like i said about the oil cooler. if you look the OEM ps cooler line is the one that runs across the x member, it feeds the diverter that sends ps fluid to the rear. so you will need to run a ps cooler from the resivor and rack to replace this one since it has a big gap in it.

the ps pump itself is completly different in the hicas to non hicas car. aswell as the resvior that is bolted up to your wheel well.

listen to what i am telling you i have been down this road already and told you everything that you will need to just swap your rear sub frame to non hicas as easy as that sounds there is a bit more involded then just swaping sub frames.

[GTChampion]

So...if my subframe comes with a diff, and my car has ABS and HIcas...will i need a new drive shaft too now ?

ive never heard of having to put in a oil cooler..buti havent looked this far into it yet..

also how do you know what PS pump you have? since my sr swap ive done nothing with my hicas but everything is still there..lines..ect..

the hicas ps pump is quite large and double sided for lack of a better way to explain it. if your running a sr then you may not be running the rear ps presure line for the rear rack. if your looking at your car with your hood open on the pass side frame rail there is a mechanism there that diverts the presure to the rear or some shit, you should see a ps hose just like the one that goes to your rack coming into that mechanism follow it and see where it ends. i bet its just kinda hanging around. look and see if you have that there or not. I wish i could take a pic of my car but all that crap is gone on my car now so its hard for me to explain try to show you what im talking about. now how did you use your ka ps pump on your sr i do belive that you cant change them over between the 2 motors. so how you kept all your stuff makes no sense to me. i would say take a pic of your set up so i could help you better.

as for how i know what ps i have. I completly rebuilt my car so i know everything that is on there and one of the many things i bought was a brand new ps pump from a non hicas car.

as for the oil cooler you guys asked for help and i told you what you need. i have done this swap and not many people have so i know information isnt really avialible for it. but if you can take a look at a non hicas car they have a line that loops around the x member it acts like a oil cooler you need to somehow give your ps fluid a way to get rid of the heat to help keep every thing running right.

No. You'll use your current diff and driveshaft. Why would you remove a VLSD for an open diff? Think about it.

The car has a cooling line OE on non HICAS cars, you can actually just buy that line instead of a cooler, or use a small frame rail mount cooler. Either way works fine.

You'll know a HICAS pump. It has two inlets and outlets. No way to confuse them.

x2. I was told you can't swap pumps between the two engines. Makes it such a pita to swap my 180sx to non-hicas.

[gotspins13]

that sounded so complicated im going to make sure i never get a 240 with hicas in the back

[S14Cuhh]

fuck im confused. screw hicas


ive..
-blocked off hicas rear lines
-swapped the subframe/dif. brakes everything is rolling and working.

[GTChampion]

Pretty much figured out ll i need to do ..i wont be addingthe oil cooler ...but chageing PS pump yeah..SR came with HICAS so..anyways someone should write a guide with pictures!

[Jonnie Fraz]

Please correct me if I am wrong, but I read somwhere that you can take the HICAS pump apart and remove the vanes that pump the fluid.

that will work, had todo the same with my rb26 swap. worked perfect!

[86is300]

what if ur swapping to a hicas rear end cause it was available, but all we really want is the hicas viscous lsd? do we jus need driveshaft back?

[txchuki4life20]

im going to do this swap soon it should b fun haha

[ke70 sr20det]

r u guys crazy no need for subframe i have hicas in my silvia swapping 2jz i just put 2line power steering pump (hicas has 4 lines) another this is buy the hicas delete kit easy thing and cut off your steering 6 7 lines and make it run on 2 lines simple is that do u guys have lotsa geez to spent for no reason...........

[recoy]

I should have made a write up. I swapped my 91 SuperHicas subframe (ABS equipped) to NON-hicas subframe and it is not complicated at all. Previously I had bought the kazama hicas eliminator bar and although I installed it, I used the 2 bolts it came with to plug the lines going to the rear making them pressurized. This is not what the kit is intended to do but it worked flawlessly. There is no need for a new driveshaft, lsd, power steering pump, etc. Everything was left stock, all I did was block the lines off with the bolts. I will admit the steering is a bit heavy and I would recommend converting over to a non-hicas pump and removing the lines at a later time, but I have driven the car with no problems for nearly 2 years now. Just to clarify the Hicas driveshaft is shorter NOT longer. Hope this info helps.

[niscur29]

Just finished up the hicas elimination a few weeks ago. I tried finding a subframe to swap but anything that required shipping plus toe arms outweighed the eliminator bar cost wise. So I removed the lines and all the plumbing. Put in the eliminator bar but then also got rid of those ball joints on the spindles too. I also did the es bushing install at the same time and pressed out the busted ball joints and pressed in a bushing. I then drilled out the hicas outer rod ends for a 12mm bolt and bolted it up. Works perfectly. Much much cheaper then doing a full swap plus adjustable toe arms.

[ke70 sr20det]

eliminetor bar will help for sure ... no need for other dollars to spend on this dilemma rather buy your self good parts for your car
