CA18DET and HICAS

[biosehnsucht]

I want to keep HICAS on my "new" S13, when I swap my old one's CA18DET in.

However, I have no CA18DET HICAS pump.

Possible solutions:
1) Find CA18DET HICAS pump (and bracket?) - Ideal, but rather hard to do.
2) Make the KA24DE HICAS pump work - custom bracket, probably could work, but I'd be downgrading from 4 to 3 ribbed belt (or is it the other way around, in which case I'm driving a 4 rib pump with 3 ribs only?)
3) Use CA18DET non-HICAS pump plus an EHPS - one for the front rack and one for the rear
4) Make Z32 '96 electric HICAS work on 240 - Not sure if doable. Eliminator bars appear to be compatible (or at least some? or poor marketing?), so it should at least bolt in place of the cylinder, and the hydraulic Z32 and S13 models share a few parts such as the middle of the arms that go between the cylinder and the suspension, so might be able to swap parts around to make it work mechanically. Then there's the electronics ...

So, does anyone have any CA18DET HICAS pumps laying about, or failing that, have any other bright ideas?

As you said, a CA18DET HICAS pump and bracket is ideal. In hindsight, I wish I hadn't thrown mine away when I first got my CA way back in the day.

The KA pump with a custom bracket is the best, 2nd option, IMHO. Then parts are easy to get locally. Fabbing a bracket if you have a welder, a way to cut the metal easily (torch or cutoff wheel), and a drill press is easy, but time consuming. If you don't have have all of those things, you'll have to pay a shop to make the bracket, and then it will be expensive.

Using the stock CA pump for the rear rack, and an EHPS system for the front may be the easiest, though not the cheapest. It will also give you speed sensitive steering assist, which should be nice.

Using the Z32 electric HICAS would be really cool, but probably the most work and the most expensive. I don't know enough about the electric HICAS rack to know if there are any other benefits.

If I had ever gotten around to building a 3d printer I could at least make a test bracket for using the KA24DE easily With enough money, you could then 3d print in metal.. but that's way more than the cost of having someone make it by hand lol. certainly documenting it in such a way would be useful for others though.

I'm fairly confident I could make the electric hicas "work" but I'd be worried about if it had significantly different calibration with regards to speed and actuation amount...

LOL, a 3D printer WOULD be handy!

the last/easiest option is also one of the most expensive options... buy a brand new pump from japan.... you wouldn't have to worry about leaky seals, bad bearings, or other small parts from the pump... it'll be fresh and if there are hose problems that can simply be fixed... o'ring problems on the racks, rebuild it
unfortunately, HICAS + CA was JDM only, it was not available in the S13 200SX around the world

for your "ultimate" / most cherished project car that you want to do right this time, this is probably the route I'd take... no headaches of chasing down 25 year old parts, no headaches of dealing with faulty 25 year old parts, no headaches of fabbing parts or adapting a Z32 E-HICAS system to work and potentially having safety/handling issues

Eh, I include that as part of option 1.
