At my last drift day i noticed a new problem with my box. Basically on one corner where I take a hairpin in 2nd and hold it at limiter for a while then quickly have to shift to 3rd sometimes it would not go in.

At all other times its fine and goes in easy, clutch kicking in third and 4th no problem but just that one particular situation when I have to hard shift from riding limiter in 2nd to third sometimes is no go. Anyone got any suggestions as to what is actually worn or about to wear out in the box? Syncros, or is third gear about to completely go?

Some more info is its a HHHDB exedy clutch running redline shockproof oil, slave and master are new aswell.

Yeah I tried it straight line and its fine only on that corner. Im thinking might be worn gearbox mount and under cornering its moving around.

Ill check fluid levels aswell.

Similar thing happened to me with my old R33, I just took a stab and filled it with oil till it dribbled out from the side and guess what? no more issue!

Worth a try right? No harm.

      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.
