how much work is in doing this, and what parts do you need?

 

You need the RS master cylinder, proportioning valve and the front hard lines. I don't believe you need the rear hard lines, but I could be wrong. From the standpoint of complexity, it's rather simple, however it's a royal pain in the *** to run hard lines.

 

the motor is out and the engine bay is striped down tobe painted so now is the perfect time if i am going to do it.

Even without an engine, redoing the hard lines is still a pain in the ***, but I agree, now is the opportune time.

 

Can I ask why you would do this? I'm not being sarcastic - the ITR ABS system is one of the best IMO and was wondering what the reason would be to ditch it...

The fact that proper threshold braking can stop you just as quickly if not quicker, plus the fact that there will be quite a bit of weight saved as compared to the ABS system.

 

you need the following non abs parts:
master and booster.front lines, proportioning valve, and the lines to the proportioning valve.
no need to replace the rear lines, for one its a bitch to do so, (you need to drop the tank for that.) just simply massage in place.

If you think that "proper threshold braking" is better than ITR ABS on a dry road course, then you are living as if the ABS technology from the 80's is what you're dealing with.

You're not.

ITR ABS is really quite good. You will be outbraking a hell of a lot of expensive machines in Summit T 5 even with ABS.

Realistically, however, if you are advanced enough that you are even thinking about removing the ABS, then you are probably on R compounds.

From personal experience, if you're on A032R or something like that, you will still be using the ABS if you have it. If you are on Hoosiers, you might think about removing the ABS because you will very seldom be in a situation where you will exert (or even want to exert) enough clamping force to overpower the grip of the Hoosiers.



Spec VR on an ITR can overpower Hoosiers to the point ABS kicks in, but you really, really have to try.

We should ask some of the Honda Challenge drivers like Jason Franza about this. I believe he kept his ABS and finds it an advantage. I believe Adam Curpier also kept his ABS.

Threshold braking is nice in theory, many of the latest H1 cars wish they had ABS in conjunction with their big brake kits.

The weight ... Bah!

I find this Extremely hard to believe.

I know National class autocrossers that can't give enough praise to the R's ABS and would Never think of removing it.

And I'm sure you can find more than a few Honda Challenge guys that will agree.

I'd expect anyone removing the system is doing so to satisfy club classing rules mostly, and then weight reduction (as specified in the post below or for a drag car) and then possibly preference:

.....ditto.

Otherwise I wouldn't have gone through so much time and expense to put the itr 5-lug + ABS on my EF.....

You can still threshold brake with the ITR system - but! It will bail you out when you overstep the boundaries of traction. I would absolutely not remove it.

 

I can't believe so many hard heads have actually agreed about something in one thread.

I wish I had ABS....maybe i'd win a race for a change....

Seems a bit chilly in hell today...

 

it is 100x easier with the engine out . its not a hard project at all . ive done it on mine .
just get the prop valve and run new front lines.

and you DO NOT NEED A NEW MASTER CYL.
the only thing that needs to be changed is the PROP VALVE

ooppss i just realize you have a R. yeah you don't need it. when i did it i had a 94 LS. so i upgraded to a 98+ master/booster.

 

what is different about the RS prop valve?

 

doesnt have all the ports for the axtra ABS lines. i think the RS one only has like 6 ports

 

abs don't have prop valve. proportining between front and rear is done through the abs modulator. it has a junction were the pop. valve is suppose to be. but that is just a way for the lines to connect to one another, no valve. so by removing the abs, you need to add a proportioning valve.

btw. i found that a 94RS prop valve is the same as jdm spec R non abs prop valve. and that a 93 gsr mater has the same part # as nsx master. the piston is also bigger.

This statement may have been debateable in the early 1980's but is no longer supportable with recent ABS systems.

Also, modern ABS systems are 4 channel so can independently threshold brake each corner. Schumacher himself could not do that (assuming he had the necessary four brake pedals to do it.)

Apart from regulations for a particular racing series demanding it, I cannot think of a single good reason for removing the ITR's ABS system. The minor advantage from the weight savings from removing it would be gone in a corner or two.
