Converting ABS to Non-ABS on s14

[ihatesmog]

I've searched but have found conflicting posts on what's needed to convert an ABS s14 over to Non-ABS. I don't have much time so i'm hoping someone can just answer my question or send me a link to where it's been oficially answered.

The question is what exactly is needed? I figured just swapping in a s14 non-ABS master cylinder and bending the stock ABS lines accordingly would do the trick. Now i'm wondering about a proportioning valve (which i thought was built into the BMC but i have no idea). Any help is appreciated. Trying to drop in a supercharger but did not plan on it hitting the ABS system.

[projectRDM]

Master cylinder and firewall lines are all you need. You may want a manual booster since it's a single chamber and not as thick.

[guitaraholic]

Shoot wanta trade, I have Non-ABS, I'd have to find out what is involved in going to ABS (yes I know hubs because of the sensor) but other than that, I'll have to check. ABS would be a nice option for me.

[projectRDM]

Adding ABS is way more involved. Way. Actuator, control unit, all wiring harnesses, firewall lines, master cylinder, front hubs and spindles, rear diff, and all three sensors.

[HYPNOTIK]

When I got rid of mine I just replaced the front two brake lines and the MC. The line that runs to the rear is the same. Everything else I threw in the garbage. If I would have thought of it at the time I would have replaced the booster with a non abs one because I like the feel better and didn't realize they were different. The abs booster is more "mushy" feeling.

[ihatesmog]

sweet, thanks. so if i am unable to get the lines is it possible to bend the abs lines that are in there to fit?

[lflkajfj12123]

i also want to do this on my s13

is it possible to get stainless lines that go to the cylinder instead of hardlines

[g-via]

there is an adapter you can buy

I am sure it will work on S14.

s0ap : I have been looking for those as well, with no luck. Please let me know if you find out anything. I will probably end up bending my own hard lines if I get enough free time to attempt it.

I am in the process of researching this matter and and would like to know, if anyone has any updates on this

[rightcoastimports]

id be interested as well.. id like to remove mine. at the moment i just took out the fuses and relays for the abs so it wont kick on.

yeap its possible

[STEVES14]

yeap its possible

Dose anyone have any pics? I am in the process of attempting this?

[the a3k]

same here, i have a non abs s14 and an abs s14 shell that i wanna swap the abs out of. im gonna use the parts from my old s14 but eventually will go stainless steel lines

[EsChassisLove]

I'm going non abs right now.

I have Z32 brakes so if u have those you need a z32 MC and a non abs booster plus lines.F not just lines, non abs MC and non abs booster.
I've heard u can get away with the abs booster but eh...better safe than sorry Haha

I'm getting those lines. Pricey but its gonna clean up the bay a lot.

[the a3k]

damn i do have z brakes on the new s14...

[EsChassisLove]

So are you ABS and wanting non abs or vice versa?

[the a3k]

the new shell is ABS with z brakes. i dont want abs.... it sucks lol

[EsChassisLove]

Ah yea Definetly get a non abs booster and z32 MC. You have 12 pistons now instead of 4. It makes a HUGE difference. My pedal is kinda mushy compared to other 240s with the right z32 brake conversion.

[the a3k]

yea i wanna do it right. im swapping my rb25 over from the non abs shell to the newer shell that has the abs.

i just need the z32 mc and i should be fine. the other parts i can take from my old s14

Chase Bays sells the kits for stainless lines.

Steve-did the ABS lines rub into your manifold also? I have maybe half an inch between the two, left a nice scuff on the polish :(.

[STEVES14]

This is a brake booster from a ABS use to be automatic transmission. But that all change when i swapped in my sr20det.

[EsChassisLove]

Wow that turbo is very close to the hardlines.....holy crap lol

[STEVES14]

In the picture it seems close but theres like 2" spacce. The manifold is from D.O.C RACE
DOCRACE.COM | CUSTOM TURBO MANIFOLDS | PERFORMANCE PARTS (http://www.docrace.com/). I think he builds them to order not sure if i should contact him and ask him if its normal. Or maybe did i get a odd ball one?

[STEVES14]

The drain line for the turbo has like a 1" space or should i say closer.

[EsChassisLove]

Looks like the turbine is not even an inch from the lines Haha. Hot hot hot.

[STEVES14]

So how about this ABS conversion to Non-ABS has anyone really completed and not had any issues?

[EsChassisLove]

The drain line for the turbo has like a 1" space or should i say closer.

It's not the drain line I'm concerned about, its the turbine being so close to the MC. Heating it all up.

[STEVES14]

The coatings help trust me! :)

[EsChassisLove]

People do it all the time with no issues. Just do it rifht and you're golden.

[STEVES14]

How do i do it right i have all the tools needed just don't know exactly what needs to be changed. What parts do i need to buy to convert this car to non-abs?

[EsChassisLove]

Already said it all in this thread. If you have Z brakes-non abs booster, z master cylinder and the lines. If u dont have the brakes then just the booster and lines.

[STEVES14]

I have already upgraded Z32 calipers, so all i need is a brake booster from a non-abs 240sx and the line? what take the place of the ABS module?

[EsChassisLove]

Nothing takes place of the module. It's deleted. Gone forever. Do you have a Z32 Master cylinder already also?

Judging by that SR setup I'm shocked you don't know more about this lol

[STEVES14]

Stock brake booster. The car use to be a automatic too, and i never really run into a issue having the abs til it shit the bad on me. Front passager side sensor is shoot 390.00. Not sprending the money on that sensor. i'd rather remove the ABS free up the engine and it will look clear.

[STEVES14]

Went with a AEM standalone unit to and i also track the car and drive it in the street too. I don't have AC,CRUZ, i can care less about it lol its not my DD.So i really want to take the abs out too,plus it a lot of dead weight gone too.

[lazysk8er2]

just get the chasebays kit, it deletes the brake booster and abs for that ultra clean look

[STEVES14]

heres a stock abs vs non abs from a 95 240sx FSM

I have most all of the stuff that i need to delete the ABS from my car. Just wondering, though, after it's taken out should i inform my insurance company? This car is my DD and i'd hate to have a wreck and then they screw me because i didnt tell them that i no longer had ABS.

my question is this what do we replace the booster or the master cylinder if u look in the diagram there two separate pieces. And what take the place of the ABS module?

[Mister.E]

Also,

Why is everyone having such a hard time finding lines? i bought OEM Nissan non-ABS hard lines directly from Courtesy Parts for under $50 just last year.

Omggggg...

NOTHING replaces the Damn abs module. The lines go there as if it never existed. It is completey bypassed.

Yes the master cylinder and booster are seperate but they are together.

You said you had Z32 brakes so go get a Z32 MASTER CYLINDER and non-abs brake booster, and to make it super easy get some of these lines ~~~> Brake Line Relocation Kit - AZ240SX.org Forums (http://az240sx.org/forums/index.php?showtopic=50482)


If you keep your Stock S14 BMC and abs booster, you will never be able to fully harness the awesomeness of having 12 pistons worth of brakes. The stock brake system was made to power 4 pistons...think about it. 4 vs. 12.

[STEVES14]

so basically the new MC is gonna have three brake line inputs vs the abs one which has 3. The the two first inputs go to the front FL FR and then one line to the rear portion valve. i think i get it know.

which brake booster did u get 300zx or 240sx? and which BMC 300zx or 240sx?
After looking at same pics online, whatever i found the 240sx one looks more compact then the 300zx one and if thats the case id rather get the 240sx one because of the lack of room i have and the brake lines get HOTTTTT:aw:

[Mister.E]

I havent gotten a different booster yet. and i forgot the size of the BMC i got. im keeping stock brakes, sold all of my Z32 shit.

anyways, here are the lines i bought with the above links from Courtesy:

http://i.imgur.com/OwtmL.jpg

[rightcoastimports]

if you have stock brakes or just z32/other bbk up front the s14 bmc can probably handle it ok. if you have rear z32/other bbk as well then you would probably need a z32 or other brand like wilwood bmc.

stock brakes - non-abs booster + hardlines you are good.
bbk - just add a better bmc pretty much... someone correct me if im wrong

[STEVES14]

i found some OEM replacement brake boosters for a decent price and brake master cylinder. Not original parts back diff a lot cheaper then going to the dealer. Thinking of going with the same year booster but non abs and deal on the brake master cylinder. All from a 95 240sx.

[Mister.E]

you found cheap boosters online?

not sure if i should trust the quality? and i found master brake cylinders too. for either a 240sx or z32.

[EsChassisLove]

Probably remanned.

My only question about the boosters is this-Is the non-abs booster larger than the ABS booster?

I seen non abs ones that look a good 1-2" thicker.

So I just called a place in San Diego called Pann Auto and asked them how many hours it would take them to do the labor on this.

Here's what the guy said "if you want to do it right we need to do the rack, so about 6-8 hours"

I asked Wtf rack he's talking about because i have all the parts already and its all install shit, thats it.

He said something along the lines of oh we might not need to do it, so about 5 hours.

I never got a solid answer on what the fuck rack he's talking about, steering rack? Idk.

Does five hours worth of labor seem legit?

i removed all the lines from my abs setup without dropping the rack or cutting lines lol. I wouldn't take it to them, can't you find a local performance shop that have worked on 240's before. It took me 30 min to remove all the lines FR,FL,R ABS module 30min so say about a hour to remove ABS module and lines. Did all this in my garage with "NO" lift.

[EsChassisLove]

The closest, most reliable/legit performance shop for 240s is 117 miles away. Garage BOSO. They are legit as hell but also charge 25 more an hour for labor.

IDK what he meant about the rack, even with my custom lines, that run along the crossmember, you dont need to remove and rack or touch it at all for that matter.

This shop is mainly a Honda shop but whenever i go there i see a handful of 240s being worked on.

[One_love_silvia]

how much of a hassle is all this? like how long would you say this would take 1 or 2 people who have never done it before?

[EsChassisLove]

I just did it a few days ago with my buddy. We've both never done it before but its incredibly simple.

We made a beer run a zip tie run and a food run, it only took us 2 and a half hours. If you need help I can help you no problem. You be the bleeder tho lol

Been a while... But i have an update if anyone cares.. Regarding connecting the rear hard line - the stock hard line coming off the rear calipers comes up and hooks into a junction block/adapter (for lack of a better term) in which has a hard line coming out of it that used to hook into the ABS module. (just follow the hard line up from the rears, you can't miss the adapter). I just took one of the old hard lines that came off the ABS originally that was long enough to reach the new non-ABS BMC and connected it. That solved the problem for connecting the rear line. For the front lines i just bought the hard lines for the non-abs model and hooked em up. Hopefully this helps someone.

[Mister.E]

nice, glad to know those hardlines i bought will work. i still havent gotten around to doing this.

is the block for the rears easy to reach? i bought the factory rear hardline for the non-abs version and looking at the image above it looks like the junction boxes are in different places. does anyone know if the OEM line i bought will reach the rear line junction box without any hassle?

[Mister.E]

ok, so i think im finally going to get around to doing this. but my question is...

will i be fine just installing the new lines and MC while still using the ABS brake booster? or do i need to source a non-ABS booster before removing all of this shit?

[headfirst427]

^^ I've got the same question...is a non-abs booster 100% necessary or will it just result in a different pedal feel?

[Mister.E]

yeah im still wondering this? i havent gotten a valid answer yet.

[Mikester]

Not necessary at all.

I deleted the ABS in my S13... never messed with the booster and it was fine. All I did was get the front/rear eng bay lines out of a junker, yank the ABS unit, install/bleed new lines & GO- it was fine. Pedal feel will change but not too drastically if you make sure to do a good bench bleed on the non-ABS MC. It will feel a bit more "mushy" than having the non-ABS booster due to the ABS booster providing more pedal assist... but you can also put a Z32 MC on there to stiffen the feel.

[rotation3x]

I did this on my first s14 when doing the sr swap. For some reason the abs box started leaking which is why I had to remove it. Anyways all I did was take a brakeline proportion valve from a 91 civic and bend the lines some and plug one spot on the valve. It worked fine with my master cylinder and 300zx calipers for the 2 years I ran with it. Far as I know its still like that.

The right way would be to buy non abs lines but I was in a hurry to test drive my car with the swap and I had a junk civic in the back of the shop so I made that work.
