Heya!

I am about to do an R33 brake conversion and Ichiba 5-stup upgrade on all four corners of my ABS equipped Cefiro.

I would prefer to remove the whole ABS system to reduce weight, increase engine bay space and just generally tidy up excessive line etc.

What is the correct way to do this?

Or do I just leave it alone all together?

Even for track use, ABS can be very helpful, and its easy to disable (fuse).

If you must remove it, pull the globe from the dash, disconnect the loom under the rear shelf and remove the ABS computer, remove all the brake lines, ABS hub, sensors, etc.

Keep in mind the hard lines on Cefiro are Cefiro only...as they're a mix of using S13 master cylinder (which will also need to be replaced) running along an R32 firewall. Making your own solid brake lines isnt hard, if you're doing the R33 conversion you'll need to make up your own flexible brake hoses too (or dodgey modify the banjo bolt), so just do them all in one hit, but yeah, I reckon keep it...more con's than pro's if you remove it.

Do you have it?

Its seems to be a rather shitty system or mybe mine is faulty?

When i hit bumps on the road while braking the ABS has a tendency to kick in and then off again making it quite annoying. This happens when under braking and the driven wheel(s) skip off the ground when on a bumpy surface, causing a bit of slip in the diff or something and (i assume) the ABS computer reads this as high speed or hard braking braking and jumps into action when i dont want it to.

I like to be in full control of my cars functions but the ABS seems do have a bit of a mind of its own at times.

I have all the gear to do the conversion including braided lines etc.

I have also just been informed that there may be some legalities involved if i remove this. Is this the case?

If I keep the abs will it work with the hubs and calipers i have?

Or do I need ABS compatible hubs or something?

While on this toppic,

What the difference with the ABS diff? I have been told its longer but will this affect my decision to put a shimmed, 4.11:1 R33 center in it?

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
