Hi People,

has anyone come up with a way of getting non-driven wheel speed on a R32 Gts/gtst? from what i've seen the RWD R32 didn't look to come with ABS, if they did i can't find a rwd ABS front knuckle anywhere.

is it a case of putting a S14/R33 front knuckle on and then modifying the ASB ring to suit a ECU input frequency limit? or have people managed to get a hall sensor onto the back of the hub and pick up the wheel studs?

 

i've searched but there isn't anything that I could find.

there are probably many ways to do it

for my bosch motorsport abs we used a r33 gtst abs front knuckle and modified the rear knuckle to allow sensor to sit and read

understand time, effort and $$ but reading from anywhere else  you get diff chatter etc where you lose 30% ish in signal clarity compared to the above

Sweet thanks mate, I did wonder if its easier to try and find a R33 knuckle and make that fit, is it just a case of changing the lower ball joint?

I'm getting drive wheel speed off the gearbox speed sensor which is fine so far to 230kph

correct Ive moved to a r33 oem ball joint - they are actually thicker than alot of the after market and similar

Get r32 abs uprights? That's what I have on my car. I've got some new tone rings if you want them. I just run a gt101 in the abs hole, pretty simple. 

I can get you some pictures on the weekend if you like

Yeah agree but probem is you cant find any!  Not many made in the first place and now like hens teeth

Another complicated thing is to run Z32 alloy hubs which have wheel speed sensors for ABS. You need different tie rod end, and you need new bearings on the upright etc. I did that as part of a major refresh when my front kingpin bearing flogged out., Alloy was a little lighter, runs a bigger bearing , gives a few extra mm in wheelbase as it moves the wheel forward in the arch (cant run crazy but can still get 8ish comfortably).

 

All in all glad I did it but was a head fark as tried it once and abandoned it the first time. sav man swung his spanners at it and got it working so using his guidance on GTR/Z32 tie rod ends etc and the required mismatch of parts was able to make it work.  Probably a 2k upgrade all said and done :(

 

I think the best bet is just look around your front wheel and see what you can pick up rotationally. You see old Escorts, E30s etc all get very creative with front uprights and the humble old angled alloy bracket.

thanks Roy, i did look into z32 front knuckles but saw it was a ballache so didn't bother. my local nissan parts dealer says he has a R32 ABS gts front knuckle, so i'm going to investigate that and see what it is.

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
