OK. So a bit of an update: I fixed the knock sensor, it turned out to be a broken wire. The speed sensor is still an issue. The engine light comes on and then the TCS and Slip light comes on. If you turn the car off the TCS and Slip light go out when you turn it back on. When I clear it it goes away for a while, then randomly it comes back. Doesnt matter on the type of driving. Also when I plug in my laptop, the speed gauge in Nistune has no reading. The only thing I can find with the same problem is this but it talks about a de-limiter and I am not aware of my car having one. Any help would be appreciated.

Oh, well in that case the dash has a fault. There's integrated circuitry in there to do the speed signal translation (takes in a saw tooth AC voltage from the speed sensor and outputs a 0-5v square wave for the ECU). That stuff would be nigh impossible to repair unless it was a broken track on the dash circuitboard or something equally trivial.

      Did tie rods. Steering now not "springing" back.

      Good to hear. Hopefully you're happy enough not to notice when driving and just enjoy yourself.

      I mean, most of us just love cars. Doesnt necessarily have to be a skyline.

      Did you pick up a manual cluster to remove the position indicator?  (Pretty sure the 34 has the gear position in the cluster, but it's been a while)

      Here is a recipe. Sonic blocks till you get one that has a good enough bore. Get a torque plate and block brace, use your choice of fasteners (arp ect) bolt the thing together empty, half fill it and let it cure. Release it when it has, go to a REPUTABLE RB Builder and get the thing line bored/honed and cylinder honed to size, then wash. Once its all clean and dandy, wash and blow it out again. Then again.  Assemble said engine to your desired clearances with oil control mods, gasket to suit desired CR/Squish ect. Attach your extended sump with proper trap door oil baffles and head drain plumbed to sump with a SUMP BREATHER SYSTEM. Build your front diff with a decent LSD, rebuild your transfer case with a few extra plates, more than likely replace your tailshaft centre bearing and tighten up the rear diff. Tune to minimise excessive midrange cylinder pressure (timing unless you like to split bores and rebuild engines) Enjoy your engine, but hate the fact you are now destroying engine mounts, gearboxes, gearbox mounts, diff output flanges and driveshafts, diff mounts, tailshafts and front CV's.   Disclaimer.... Ive never done any of the aforementioned stuff.......

      440s will support well over 400HP on petrol, which is a decent place to be for an RB20. 230+rwkW. Will be a safer bet for idle/low load. 550s would be nice for the extra headroom. I've made the same decision with mine (Neo25). 1000s are probably too big for the Nistuned ECU, so I have some smaller ones.
