Right, blocked the rear outlet from the pump, and also the return to the reservoir.

Haven't yet swapped out the Hicas rack, but there is Power Steering fluid pissing all over from somewhere or other. I thought it was from the main return to the reservoir, so replaced it with a braided hose, but after taking it for a run out, there's an explosion of fluid all under the engine, hoses, suspension-everywhere.

Is there a possibility that the rear outlet being blocked is causing excess pressure in the system?

nope...we have had no problems at all with the setup, and it has had quite a workout last week ;) All I can suggest is that you follow every line again :(

Well, it's coming from somewhere:D Can't tell exactly where as it sprayed about a litre out yesterday, so I've taken the vanes out of the rear of the pump to see if that'll help.

I don't see how it could come out of the rear output hose that is disconnected, (where I thought it was)seeing as how the return to the reservoir is removed and blocked up too. Is there a feed from anywhere else into the rear system apart from those two?

Thanks

Mitch

hmm I'd drop around and have a look but I don't think you are local?

Its not really that complicated once you have the right pipes. One pump outlet (front) should go to the steering box, then to the resovoir, then back to the pump.

The other one (removed) goes from the rear pump outlet to the solenoids in th engine bay, then back via the wierd cooler thingy to the other resovoir outlet, then back to the pump. All that gets removed and you block off the pump and the resovoir outlet. Finally there are 2 more lines from the HICAS solenoid right to the HICAS bar at the back of the car. these come out too.

You might be able to spot the leak by having someone turn the wheel while engine is running. Good luck

Hey, any news on possible removal of the HICAS computer on ECR33. I want to stick some amps in there and the extra room would be nice :P

(Already have lock bar installed)

Update on the HICAS ECU:

I now have no power steering at all.

I read in another HICAS thread something about the weight of the low speed steering being effected, but I have no power steering at ANY speed.

Not sure whether I like it or not yet.  The steering is quite heavy even in fast corners but it actually feels more direct and comunicative.  I will have to take it for a decent run through some more demanding corners and see if I can deal with it long-term.  I suppose I could just carry the ECU aroung and plug it back in when I was feeling tired/lazy :rofl:

This is fairly common and is likely a result of the controller not having a rear steering angle to input for the power steering modulation. At least in the 33 the "hardness" of the power steering is controlled according to road speed, and after the lock install will get become heavily weighted at low speed, when it should be lighter. I noticed the normal heaviness at about 80kmh.

With extra castor dialled in at the front for the track it is no longer noticeable.

Umm I should add a troubling development to my instructions....it could be co-incidence but more likely bad news.....the power steering pump on the car has got very noisy recently....

I would strongly suggest looking at PHATR32's suggestion....or saving for a 33/34 power steer pump :P

eeeeekk!!!

just as I have followed the Duncan method...hmmm

what is the PHATR32 suggestion? I couldn't find anything specific previously....

and dare I ask what a 33/34 pump costs!

(looks like the only bonus right now is that it gives easier access to the oil filter with all that crap removed!)

basicly you take the ps pump off and undo the the 4 bolts on the side of it.After you remove the cover youll see a little impeller pump thing which slides out.

Luckly the outside impeller is for the hicas and is easily removable.

Then you close the the pump up and block the outlet with a bolt.

If you dont remove the impleller and just block the hole, the pump will still be pumping the fluid, but because the fluid has nowhere to go, the pump will start to heat up and leak. maybe even wear out eventually.

i really should get my shit together and post up some pics.

ok looks like I will have to do that soon before there is serious damage... Im hoping it is an easy job... does it loose much PS fluid?

and as you describe, it just slides out, and bolt the rest back up?

was expensive enough to get this far.... as here I was thinking it was a small job, but it took the guys a fair bit of time while they were fitting all the other gear....

A couple of things to add:

- As hinted at by several people in this thread, the HICAS controller in a R33 also controls the (front) power steering weighting. So disconnecting the controller results in the steering always being weighted at the 'heavy' end of the scale, whereas normally the weighting is proportional to speed - slower = lighter for easier parking.... Note that AFAIK R33's w/o HICAS have a seperate power steering only controller located in the same location as the HICAS controller.

- No-one has said this explicitly I don't think, note that the HICAS in the R32 and R33/34 is different: R32 uses hydraulic actuation whereas the R33/34 uses electric actuators to move the wheels. So comments about power steering fluid lines at the rear only apply to R32's....

In R32 gtst, if you disconnect the plug from the HICAS controller in the back the steering goes heavy as well.

I had to disconnect mine as when HICAS kicks in at around 70 km/h my rear comes out and it creeps along. I have to turn the steering wheel to 2 o'clock to keep the car going straight.

So will this bar fit the R32 gtst?

Is there any way to have the lock bar and not get the heavy steering? There must be some sort of controller to replace the HICAS one?

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
