hicas or to not hicas??
 

why is it so popular to eliminate hicas on s13?? i understand that it will make my steering stiffer but why would you take it out? anyone out there who upgrade their hicas?

HICAS 240sx chassis are the heaviest in there class weighing a little above 3000LB's. This also makes them the slowest 240sx's on the track.
If you do not want hicas it is an easy conversion.
One upside to the HICAS 240sx's especially if it is in the U.S is that it comes with VLSD. The majority of s13's don't come with VLSD unless offered as a special expense throguh the dealer ship.
If I were you get the CAR, remove the HICAS, and keep the VLSD.

do you literally take super hicas out? how much weight could it take out? i always thought hicas would help with track time.

nah, i heard it helps with parking though. even GTR guys eliminate HICAS. you can purchase an eliminator kit. one thing however, is that the VLSD is over 15 years old and will not exactaly be awesome or anything.

i'm trying to upgrade to a hicas front streering rack in my non hicas s13. the ratio in that rack is super duper.

so how much weight will this take out on my vehicle?

The entire hicas system removed will take off about 100LB's of crap.
Just for reference my s13 weighs about 2700lb.s it's a coupe model. HICAS 240's weigh about 2950, give or take some of the safety crap added after my year.

How come there have been like 4 HICAS threads in the past days?
WTF is going on

100 lbs is a pretty big difference. Seems like it would make more sense to get a base model 240sx and put in a 2-way lsd or a torsen.

the hicas eliminator seems expensive, like 450 bucks.

The weight isn't even what makes hicas 240's slow either. It's the power steering fluid that has to be pumped through the system that eats up all the HP.
I don't even know why the hicas system was made my brother had super hicas on his 1991 Q45 and it had a leak inthe system. When we would go passed 60MPH the rear wheels would wobble.

is there anyone here who has installed a hicas eliminator and felt a lot of improvement in their vehicles perfomance? any companies for recommendation?

Im pretty sure that earlier HICAS systems used fluid like in the Q45, but the newer ones called SUPER HICAS are electrical, and faster.
All that besides, who knows if it will actually benefit anything.

Super HICAS started as early as 1990 and were power steering fluid controlled units. My brothers Q45 was a Super HICAS 1991 Q45. I don't believe that Super HICAS changed to electric power until 1994~1995, when later the infiniti models would be labeled with a t at the end of it's badge.

BTW I thought I would make a correction for you a KAZAMA HICAS eliminator cost $110 and it allows you to keep the VLSD an the install is very easy. Here is one installed on the Nissan Skyline R32.

Now the only difference between the HICAS eliminator on the skyline is as you can see it is electric rather than using power steering. In any case it can be removed for free and you could pick up a junker non HICAS power steering pump at a junk yard for dirt cheap. Problem solved... A VLSD s13 with no HICAS for $200 in parts and swap. So I just proved keeping a HICAS 240sx and converting to non HICAS to keep the VLSD is cheaper than buying a used VLSD for $300, and looking for an s13 with no hicas.
FACT: The VLSD's found on the 240sx's are in much better condition used than one from J30's, silvia's or 300z's because the KA24de 240sx makes less torque and HP. As long as the VLSD was well maintained with fluid changes it will out last a VLSD from a J30, 300z or even Silvia's.

As I promised $110 from project Nissan.

Vin, Since the VLSD is fluidic, how could one be in significantly better condition then another?
Wouldn’t you want to change the fluid anyway?
Doesn’t changing the fluid effectively bring the diff back to nearly new condition?

It is my understanding that, unlike clutch and helical diffs, fluidic diff’s sustain very little mechanical wear, about the same as an open diff. And that the stesses of a 220 HP engine are not enough to significantly wear the diff's used in Nissan/Infiniti's.

I ask these questions because, while I don't mind being wrong, I hate being ignorant.
