Stripping ABS and Power steering


We were bashing on a guy recently on TennSpeed for wrecking his EM1. He was pissed cause Honda didn't put ABS on the EM1 but we were able to drag it out of him that he was not driving how he should have and tried to stop too fast at a stop sign, locked his brakes, and went through a barbed wire fence when the road was damp.

NOW as for racing ABS can be a god send (I guess, I don't know from experience), but if you are as good Keiichi Tsuchiya I'd say you don't need it. As for dailying, I doubt you need it but unless it's a power robber, I say keep it. As I previously stated however, you could easily lose P/S. I went from an EJ1 with P/S to an EJ6 without it and it don't bother me none. I just like having it in the delivery truck at work.
 
Yes I agree with the keeping the ABS for safety reasons. But as for PS, I've heard some ITRs making extra 7whp just by removing PS. It was said in that link I posted.

I'm really keen on doing that mod... and it can always be restored back anyway.

I'll post up better pics and instructions when I do this mod. Hopefully soon... but right now, just looking at all the lines, it's not going to be easy to reach there. I may have to jack up the car and do it from under. I'll keep this thread posted for my next mod

I raced for 6 laps on a 2.5 km track last weekend, I had to removed power steering just before the race..

My arms still hurt lol, don't remove the power steering! :nerv:

Apparently if you just remove the belt off a Power Steering car, you'll make it worse and stiffer than a car that hasn't got NO Power Steering to start with.

I just found out why and it's because there are 2 types of steering racks, 1 is PS and 2 is Manual steering. Because you pulled off the belt, the fluids in the rack are not circulating, so it makes it worser than a non-PS car. As your trying to steer the wheel, your trying to push the fluids from the rack to the pump. :nice:

This is why your arms are sore LOL

The point of this mod is to remove the Parastic drag without sacrificing the drivability.

the mod is to be able to remove the parastic drag, save weight from the pump and not needing to change the steering rack to a manual rack.

So for this mod, you have to link the inlet and outlet lines together and drain the fluid and have a breather to the line so that when you steer the wheel, your actually pumping the fluids at the same time which will give you the benefit of PS without parastic drag from the pump and the pump removed to save weight.

Today, all of it makes sense now. Hopefully I can write something up about it with dyno tests. :)

Thanks for the information, I didn't know this, thats why my car was not drivable! :nono:
 
hey no probs...

I just thought I'd also say an ITR gained 7whp! And 10ft pounds of torque @3000rpm

Hope that stirs up some interest :D
 
I tried my last K20 EK without power steering - never again.

I could live with the difficulty parking, but on track, going round a tight corner with the diff kicking in, trying to power out and hang on to the steering wheel - impossible and dangerous!!:nono:

Thing was I couldnt run a standard PAS pump as my ITBs were in the way so I'm using an MR2 electro hydrulic system:

The guys at Hondata used this setup to save power - they reckoned 6BHP on a B16.

As for ABS - I like it, but can be a PITA on track as the pump tends to run on a bit too long so when you are stabbing your brakes progressively into a corner, once the ABS comes on you lose all brake control.. Just switch it off for track:)
 
Yes, I think I already mentioned that you can't just take off the belt and pump because you have a PS rack.

Read up abit.

Also this mod gives you the benefit of having PS feel without PS.
 
Yes I did this mod - and it was like I said - a nightmare.

I looped the pipes, drained fluid and put in a breather.

And how is that then? You remove the assistance and then you are trying to manually move a rack designed to be under hydraulic pressure!! An un assisted PAS rack has a VERY different feel from a manual rack.

Only way to really do it is to fit a non PAS rack but not sure what EK/EJ models came with no PAS. Or fit a DC2/EG subframe and get a DX manual rack.
 
hmm, interesting... I guess I'll have to try and see the difference. Thanks for the info
