I know hicas is 4 wheel steering, and i test drove one with this feature... it was pretty cool doing a u-turn with it... but im interested in learning drifting and other techniques so i dont think i want 4WS...
So i have a couple questions? First I was wondering how to tell if a car has HICAS? and Second I was wondering if most cars in Canada come with HICAS?

First question:
1. check the VIN plate inside the engine bay. The chassis code will be RMKS13 (the car has to be a fastback, 91-93) 2. check for a HICAS dummy light in the gauge cluster 3. in the black stripe along the side of the car, just behind the door it will read 'SUPER HICAS' 4. get under the car and check the differential. If you see a cylinder with two arms coming out going to each rear wheel, it's HICAS. Second question: This was a myth perpetrated by an email list and furthered by MANY users. No. Also, even if you find a perfect car, except that it has HICAS, remember that you CAN disable it. Edit: I was slightly off about the chassis code. It's now corrected. Kevin |

Disable? Pull a fuse, or if you really want to be thorough, yank out the whole system.
Yes, it will be expensive to fix, as the parts are only going to come from Nissan. It's not like a shock you can blow or a wheel you can bend and get aftermarket replacement parts. You MAY be able to find rebuilt parts, but good luck. |

There are HICAS eliminator kits you just have to have a overseas hook up to get it. It's not widely sold in the US.
But if you want to do it your self here is the trick 1. Have a shop fab up a straight rod to go between the "steering rack" in the ass end just to make sure that the rear tires don't move or shift position 2. Loop the steering lines that run to the rear so you will keep pressure (looking at you engine bay they will be on the far left at the very bottom) 3. Voila! your done and you get to keep the LSD (which you would probally have to remove when putting in a non HICAS rear end). FYI your HICAS light will come on

You could keep the LSD regardless. The HICAS unit is placed at the upper rear portion of the differential, but is by no means integral with it. |

yeah i have HICAS and its a pain in the rear! get it? pain in... nevermind. im eventually going to the junkyards and pulling the whole rear from a non-hicas 240 and swap it all in while keeping the LSD. hopefully it will be pretty straightforward. only reason im doing it (besides the fact hicas makes it hard to drift) is so i can run aftermarket shocks in the rear. the arms that steer the rear wheels actually attatch to the shocks and use them to steer. way to go nissan! that sucks. at least this is what i gather from all the things i have heard. HICAS. what a nightmare for people that know how to tune cars and drive them without aid of computer controls.
im thinking of putting some nice bushings in all the new rear pieces while they are off. seems like the logical thing to do. and what are those spacers that go between the rear end and the chassis? uras monkey magic of japan calls these "drift pineapples". i suppose it gives the suspension a better angle for drifting? how does this work? where can i get a good set to try out? thanks for any help. chris |

shinshu180sx is right. hicas and drifting are harder. the car is trying to correct itself while you are trying to keep traction away in the rear..doesnt work well
you can do the subframe swap of course. there are also hicas cancelling bars (a lot of Japanese companies make them, one is Kazama that comes to mind) also those MOnkey Magic Drift Pineapples are VERY available stateside. if you buy the monkey magic one your paying for the name. i got ones from Greg Dupree (there were group buys on them). they are subframe spacers. basically the compress the subframe so elimiate slop (which helps reduce wheel hope) BUT for you shinshu180sx, since you are replacing the entier subframe, the monkey magic one (the bigger kit-like 8 piece-not the 4 piece) you should get. you can also get the Whiteline Kit which is the SAME thing!! so be careful on the brand you want. just because its japanese doesnt make it any better then the exact same product stateside (specifically espcially something so simple as these drift pineapples!!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=''> anyways, hope that helps. |

I believe that Jim Wolf Technology has a disabler for the HICAS. you can get the phone # at www.jimwolftechnology.com

thanks dousan and ryno.
i know there are other companies that make the spacers, but i just thought "drift pineapples" would be a more easily recognized name for them. i guess i was right! haha so yeah i think the whiteline stuff sounds pretty good. doesnt PDM carry a lot of thier stuff? i might as well get the whole bushing kit for the back since i will have all the pieces off the car and i might powdercoat them some nifty color while im at it. wow when i get everything on i bet the alignment shop will hate me! "man, what did you do to this thing?! its WAY off!!" haha as for the elimination kit, i think i would just get rid of the system all together to save wieght. i mean, the pump itself has to wiegh like what, 20 lbs? yeah, its outta there. but i will look into the elimintation kit since jim wolf is right up the street from me (well like 30 min.). thanks for the input! chris |

Why would you want to get rid of it? How does it screw up drifting? All mine did was help everything. The stock handling on S14 is very disappointing. . Got so used to HICAS.
Drifting (not saying I'm a pro) was very easy with it, it never got in the way. I guess I don't understand the mentality of wanting to throw a gift away haha -Rob |

Yes, the "aftermarket struts won't fit HICAS" is a myth perpetuated by manufacturers of the shocks that don't correctly read the factory parts lists. The HICAS cars had struts with more aggressive damping from the factory, and hence a different part number; but they bolt up just the same.

if you tried a s13 w/o hicas you probably would have noticed the difference. maybe it was the speed you were going? |

I've driven a couple of S13s without it, handling feels as bad as it does in my S14. . (of course, HICAS is a complete system and not just rear wheel steering tho. . ) |

interesting...
my s13 is so nimble its ridiculous. i drove a friend's (2) s14s and it was like driving a boat crazy my car's stable at high speeds (60ish+) drifting. but i'd like to try a hicas one one day. just to see what its about. of course one slide isnt enough, gotta chokudori it and see how it goes. maybe 3 consecutive corners might see the downsides of it. |

S14 is the worst of the bunch, took me awhile to learn how to control it. . springs will fix that. . haha. . . ugh. . Oh well. . . Yeah u need to drive one!!! you might like it. . Everyone says it's invasive and twitchy, but. . I disagree. . nothing like .95 G STOCK on H rated all season tires!!! compare that to .88 G with S14. . |

**** dood, I feel like I'm one of the only guys who would trade up to HICAS in a heartbeat. . . :P
And here everybody is trying to kill it.

For the street, keep the HICAS... it's a hell of a cool thing, IMO. . Plus, you get VLSD, stiffer stock springs and thicker stock sways (which most people replace anyway haha, but still...) and you get a tighter ratio front steering box. . All adds up for some impressive feel, and amazing handling. . Don't get me wrong, my S14 handles okay, but it's total ASS compared to my HICAS S13, and I knew what I was up against b4 I bought it. . (and I'd make the decision again) fresher, newer S14 > rusting 140k mile S13. . |

***UPDATE***
okay i drifted the **** out of my hicas s13 at drift showoff and it felt fine. aaron if you wanna try a hicas car next event i go to you can try mine. if i can try yours mwahahaha! j/k nah you can try mine though its all good. so anyway, maybe hicas isnt so bad. its hard to break loose initially, but once its sideways, there's no stoppin ya! and i only spun out twice all day! heheh. and as for the shocks, i was thinking of just ordering some more agx (i already have fronts mounted) and just see if they fit. the more i think about it, its obsurd that nissan would make a car you cant replace shocks on. that was rather ignorant of me. other things get on my nerves though. the biggest thing is that i cant get an aftermarket steering wheel because the hub and entire steering shaft are different on a hicas car because there are steering angle sensors they had to change everything for, and nobody has made a hub adapter yet for that design. and i was having serious leg clearance issues at drift showoff. i have to heel-toe with the side of my foot instead of my heel. it sucks. new question: how low can you go on AGX? i'm about to mount some adjustable springs on there (ground control type), and i want to know how low i can go before the AGX's are ineffective. anyone know? if not, thats cool. i can just play with it until i figure it out. oh yeah and aaron, it choku-dori's like a champ. chris TEAM DUCK SNIPER |

I was considering doing it from a HICAS S14, but since ALL HICAS S14s were Silvias, and thus RHD. . I dunno. . I'm not mechanic, but I bet that won't work haha |

People ship rear subframes all the time, an S14 HICAS rear subframe shouldn't be impossible to get.
But then there's the wiring/controller, and power steering lines to the back, etc... not easy stuff to add. |

1. Steering rack 2. High pressure fittings and lines 3. Rear subframe (w/ tie rods) 4. Steering pump (HICAS has an additional line coming out) 5. ECU from HICAS equiped car (which will be for a SR so be ready to swap on the s14) In my opinion not worth the trouble. I have a HICAS s13 and it's not really a big deal) It does help keep the a$s end behind you on the track though Edit: Forget about getting coilovers because you will not be able to keep the correct toe and camber that HICAS requires to correct it's self for steering input
