Hey guys been chasing the reason the ps has been heavy for a while and its just occured to me that its a non hicas motor and loom and the car was originally hicas so the solenoid on the rack is unpluged caz there is no plug to plug it in, can I tap into the hicas ecu and wire it up to fix the steering or is there another way around or thing to do ?

If you want it to work properly, then yes, you need to put in wiring equivalent to the original HICAS wires in the old loom. There is a way to bodge it so that you have feather light steering all the time (which is just to give 12v and earth to the solenoid all the time) but that's a bit shit, and I wouldn't do it.

You're going to need the wiring diagram for your car to be able to pick up where the HICAS wiring is currently finishing up in the engine bay. I'd say it's hanging about somewhere near the fusebox, but could be wrong.

It definitely comes from the HICAS computer, but the point is that the wiring that comes from the HICAS box to the front of the car will still be there. You just need to pick it up at whatever loom/body plug it ends at and carry it on to where it goes. Hence why the wiring diagram would be useful.......

well, if anyone is still interested. there's a pink wire that goes to the nolex type or white plug that sits between the fuse box and the washer bottle, that's the switched supply from the hicas module. then the grey connector above it has a straight black one that's the earth in the original loom.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
