This is going to sound like a really strange question.... but

I have just recently had new tyres fitted to the back of my R33 gtst ( 265x35x18)

and for some reason the steering is now reacting really badly. I was maybe even thinking that when the tyre place changed the tyres they might have jacked it up using the HICAS steering rack instead of the Diff.

So what I need to know is with the HICAS can you actually see it moving when you turn the wheels when stationary or very slow? ( like I know you can on Hondas with 4 wheels steer)

or does it move so slightly that you can't see it?

I can't see mine moving so if they are meant to then I have found my problem.

If someone could help me by looking at their line I would really appreciate it.

Thanks

And...  FYI...  He, is a she...  :P

Who is a She?

Any way Thanks for the help fellas,

So Hicas is set up for high speed cornering?

I thought it was like the Honda 4 wheel steering and was set up to only work for low speed cornering, moving only a couple of degrees?

Does anyone know how to run a diagnostics on the Hicas, cause I have no way of knowing if anything is damaged.

I took the car back yesterday and they put the car on the hoist, you could quite clearly see where the jack had hit the hicas module.

they said it was only a minor mark and they reduced the tyre pressures down to 30 psi to solve the problem ( my opinion that only masked it)

Not sure what I do from here now..... Guess I take it back down to Gavin at Autotech and see if he can find anything wrong!

Thank again for the help

    • I hope one day I can do it like you. Your engine looks great.
    • If there's nothing else I can do I'll probably do something like that Someone on the internet said that ca20s and ca18 engine blocks are the same and that you can use a ca20 engine block and put ca18det parts to make a ca20det Do you think this is possible or will it damage the engine?
    • Yeah, I did some research and found out that some things are different.
    • Makes sense, thanks! Consider me very impressed. And I very much appreciate the effort in documentating all of it. You'd be surprised, or maybe not, how many people this reaches who search for things online. Anyways, I shall continue to read all of it, understand maybe a quarter, and hope that some of it sticks if I ever end up in a situation where it's relevant
    • 'Did' work on them is more accurate ~ on the R31 Skyline forum, you can spot me as 'Solder'... I've written quite a bit about the 4R01 boxes there, and I ended up reverse-engineering the older TCU type operations, so we could fudge a custom TCU to pull off other tricks...and like all things, when you do it a lot, see the failure patterns, have to find parts etc etc, your head ends up filled with whys and wherefores... there was a reason Nissan went with these in more than 60models over 16+ years... all in all, the JR401E based design is an interesting study, as Nissan changed things over the years in a never ending battle against them lunching on themselves <grin>...by the time the RE4R01A rev.C came out (often referred to as RE4R01B), they'd more or less perfected the design...
