Hello to all. this is probly a really stupid question but if you don't ask you don't know.

what is HICAS and what's it do and do i have it? i own a 93 series 1 na r33 and the HICAS light stays on i've heard this is because i have an aftermarket steering wheel i asume i have it because of the light but i'm not sure. also i've heard of people blocking it off what are the advantages of this? any info would be good thanks

well this is what its said about it

"HICAS (High Capacity Actively Controlled Suspension) is Nissan's rear wheel steering system found on cars ranging from the more recent Skyline and Fairlady Z (300ZX) iterations to smaller models like the Nissan Cefiro (A31), 240SX/Silvia (S13 & S15)/180SX and Nissan Serena/Nissan Largo. It is also found on models from Nissan's Infiniti division, such as the Q45 and the M45/M35. Unlike other four wheel steering systems, HICAS and Super HICAS are fitted to improve handling rather than as a parking aid.

Earlier HICAS versions used hydraulics to steer the rear wheels. The hydraulic system was powered by the power steering pump and used speed sensors to determine how much and in which direction to steer the rear wheels. Later versions, called Super HICAS, moved to an electric actuator for the rear steering rack, making the system much lighter. The Super HICAS system also used its own computer to control the system instead of speed sensors. HICAS and Super HICAS rear wheel steering is limited to about 1 degree in either direction.

HICAS was introduced on the 1986 Skyline GTS coupes (GTS, GTS-R, and GTS-X). The system was later adapted to work on many models in the Nissan range, beginning with the Passage GT."

i guess it cant be worded any better than what ive posted

    • Factory LSD is supposedly a 2 way with a very conservative cam. If you've already tried adding friction modifier to the diff oil and it still locks up too much for your liking you might want to adjust the ramp rate on the cam to be more like OEM instead of reducing initial torque even further. People claim the 8 kgf-m disc kit for the OEM LSD is still very streetable but I've never been able to compare everything side by side on my own.
    • Oh man, at least it sounds they've accepted they stuffed up and not put it back on you...could see some confusion if they asked if it had a hardtop or not, and you've answered truthfully but maybe not answering their real question which is what roof did it have from the factory! Glad your keeping it N/A 2.5
    • Nah, I much prefer colour matched Talking about colour matching stuff, the new/used boot lid turned up, all painted up perfectly......aaaannnndddd, it's for a power retractable hard top, not a soft top.....LOL They are now sending a boot to fit a soft top.....,  whilst frustrating, life is like that sometimes, sometimes you just need to dodge, duck, dip, dive and, ummm, dodge.
    • You would need to paint your hardtop again though
    • I have an old R32 in the shed that hasnt moved much in the last few years and probably should see the light of day. At one point I had a Nismo 1.5 centre put in the rear diff. It is a clunky nightmare POS of a thing on a good day. To make it less painful the initial torque setting has been put on the minimum (7.0kgf-m, mid is 9.5, high is 14) and the oil changed out to something more slippery. But it is still awful and ruins the vibe of the thing. So my questions are: Given I have the original parts sitting in a box somewhere would it be better to rebuild the thing again, reverting to more purity? Is there a standard kit or do you just go and replace the friction plates etc and shim it the way you like it. How much initial torque does the standard R32 rear diff have? Or does the Nismo disc kit offer a better solution - the caveat being the initial torque for both options appears to be higher than the clunky 1.5 way. There appear to be two Nismo disc kits: 3843S-RS520 for 8kgf-m. 3843S-RS521 for 12kgf-m. Or is the easiest solution to reshim the Nismo diff to make it looser?
