steering is heavy as a fat chick...

drifting is controlled and predictable

steering shouldn't be any heavier....

have u disconnected the hicas ecu? coz that will fark with your power steering up front too.

didn't touch power steering... just the lock bar...

there is a few people on here that have exp'd the same :)

R32 or R33 GTR? And did you disconnect the HICAS ECU?

The tutorial explains how the installs are done in the tutorials section of this forum, R33 should not be an issue, not too sure about R32's.

I did a fair bit of reseach on this, as I was having trouble with the Hicas shuting down on wet days, the power steering would die along with it, all attempts to fix it were only temporary, so it had to go.

From what I read at the time (06) the lockbars on a 33 would cause the pwr str to either die out because the hicas was disconnected or be restricted (it was never clear to me which) and also nobody had any to sell me, so i bought the Tomei kit which locks the hicas physically and reroutes the hicas with another unit, pwr str works fine and no interference from a computer when the hairy stuff happens.

If you have ever dropped a long side skid with hicas, it will kick the car back the opposite way ie you cant drift.

If the steering is heavy or craps its selt its because you have not removed the hicas correctly.

Before after I much prefer no hicas; much more predictable and the steering actually feels a tad lighter and more willing/easier to make corrections mid corner.

Kicking the car back etc is a load of crap; the rear steer is so little it will not kick the car back just make it feel not as predictable.

The 4-door R33's have no HICAS but they do have the power steering ecu in place of the HICAS/PS combo unit. Is it advisable to lock the HICAS unit and then change the HICAS/PS Combo ECU to the Power Steering only version from the 4-door models. That should eliminate whatsoever HICAS problems with R33's. Please confirm on this.

Most of the HICAS problem i've heard are from R32's cause of hydraulics, the R33's are electronic which makes it easier to eliminate.

he did install one but the hicas light wouldnt stay off and his steering was heavy all the time! So he out the standard one back it just plays up everynow and then nothing to do with the steering wheel as it was acting strange b4 he put the new one on! It's not the power steering fluid anything else to check?

I have a 32 and removed the whole system. The car drives so much better. Pretty sure when i was reading that for a 33 you have to either remove the warning light from your dash or cut the wire going from your hicas ecu (under the parcel shelf) to the dash light. Someone correct me if im wrong. But leave the actual ecu connected or u will get heavy steering. Deffinately comes up when u search anyway.

Did he follow the HICAS tutorial in the relevant section of the site?

I'd say no, because his power steering stopped working AND he didn't remove the globe, of course when HICAS is locked the warning light will go on.

Does he have an R33? Did he attempt to disconnect anything inside the car? (Don't!)

Note: before installing the lock bar the warning light would come on, mainly after highway driving and the car would feel strange while its on. There are ways to run the HICAS diagnostics but I just removed it and the car feels better for it now, I'll find out how much next track day :D

      RB20DE NEO smallbox clutch.

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
