Hey all,

I just had a new HKS GD Max (sprung centre) twin plate installed into my 33 GTR. The shop ordered the genuine nissan release bearing specified in the clutch kit as well as the flywheel bolts, everything else is supposedly supplied.

The issue I have is that the friction point is now at the very top of the pedal travel. I complained and they first shortened the travel of the pedal and also re-bled the entire system. All this did was lower the pedal height but not change the friction point.

I took it back again and was told that the only way to change the friction point would be to shorten the slave cylinder rod, I said ok. Had my car for the day, get it back and they said we actually did not do anything, we think that shortening the rod will not work, you have to upgrade the slave cylinder to a Nismo which means you will need to push the pedal down more to shift the additional volume of oil (as it is a bigger slave, with bigger volume), which will therefore move the friction point down the pedal travel.

Does this sound right. I thought that the bigger slave cylinder would mean that you would need less pedal travel to move the clutch not more??

I am in Perth so if anyone here has the time to check it out and give me some ideas, I would really appreciate it but at the moment I am afraid to give the car any stick for fear that the clutch will slip and after spending $2750 on it I really do not want that to happen

you can lower the pedal height by adjusting the master rod on the clutch pedal in the car. also a bigger diameter slave will take more travel to push the clutch fork the same distace, (makes it lighter) but you can usally adjust this out using the master rod in the car,

very simple really,

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
