How-to - R32 GTS Hicas removal

[nickdutch]

this worked amazing just did the removel step by step and it turnd out grate speed sensetive stearing is still operational no hevy stearing ether no need for non hicas pump as the hicas loop is just turnd into a cooling loop and the wire cut dose infact work the hicas light still comes on when you are lowe on psf and eny uther thing it coms on for sum one needs to stiky this i got so mutch yousles **** out of my car stearing re alinement is a must tho

Easier to fit a R32 Non Hicas powersteering pump + mounting bracket from non turbo model (saves weight). Or some use R33 powersteering pump (saves weight). But I think with R33 pump, mounting bracket (pump is shorter due to no HICAS pump on rear of powersteeing pump), amount of grooves on pully (grooves on pully on front of powersteering pump that matches amount of grooves on crank damper) is different to R32 HICAS pump.

On tight 90 degree corners you get understeer (rear wheels grip more). That's about it. Upgrade rear swaybar and should reduce or eliminate (depends on size of swaybar) the understeer.

If HICAS ECU has a error code (heavy steering due to HICAS ECU limp mode)due to missing HICAS solenoid in engine bay, then can earth plug in engine bay or near HICAS ECU, so HICAS ECU thinks HICAS solenoid is still there. Can do same thing with cat sensor to turn light off on dash by earthing cat sensor (strap cat sensor to side of exhaust with intake hose clamp).

if you do the pump mod, do you still need to re route lines or can you delete all that stuff?

[Boyscout]

so what do you do if/when you lock it out and the steering does get 'heavy'?

anyone have an answer for this?

[NismoS-tune]

you can modify the GTR pump to delete the HICAS loop. Easiest fix is a tomei lockout kit, cheapest is like he says.

[whiteboy87]

should be the same idea for the gtr and no you will not have to recirculate if you have a non hicas power steering pump you can loose all the hicas lines all the way to the engine bay if thats the case. i havent dont this yet because im still waiting to pick up a non hicas rear subframe, lose more weight that way

[cschepp]

Does this work for a gtr? And also if you have non hicas ps pump will you need a recirc?

[kyles_r32]

I was taking a look to see if the previous owner looked out the hicas and i noticed theres no ecu in the back at all theres just some wires with the pin connectors dangling there

Awesome thread!!

Thanks again.

[COGTR]

i would assume and hope its probabaly the same since this is an awesome write up and im going to use it to do mine. makes me more motivated to actually go do it.

[benk23]

awesome write up! is this the same for a GTR? i dont see why it wouldnt be

[SyCo]

hah, you beat me to it dude, good job!! I took a bunch of pictures of when i put in my lock-bar a while back and have been meaning to write it up. This looks top notch. If you don't mind, maybe I'll add the pictures and the part of when i opened up the Power steering pump to remove the fins to avoid a pressure back up.

Yep go ahead... but in my case it was not needed since I recirculate the fluid going from the back part of the PS pump. It goes in the cooler (which is simply an aluminium tube) and then back into the reservoir so there is no pressure and no need to remove the impeller.

I may be mistaken but I don't see why it would not flow freely if there is no more "restriction" (usually the rear hicas rack and solenoids).

Feel free to correct me if I'm wrong or add details if you wish. :wink:

, holy crap dude.

It's a great thread man and yeah I'll Sticky this one too. I'd see keep it coming but I think you would and in which case, we'd have the whole first page full Sticky's :P .

But yeah it's a super job man. :wink:
