The real NISMO1 Posted July 13, 2014 Share Posted July 13, 2014 She's going good. Pretty much anybody can drive the car now. This clutch is just so easy to drive compared to some others.Hi Richard, you have the Super coppermix C twin? I found as my mods started to give the car some torque/response, the OS Giken Quad clutch became much easier to use as a DD and I have no doubt it will be even better after the stroker build BUT from what the blokes have said that have a similar set up, I would be nuts not to get a quality sprung twin clutch that will be more forgiving on the box. I will have to think of selling off the leftovers, the RB26 block, the motor mods and clutch have only 3500Klms, forged internals etc and I do not want to bring any of them back home with me. So once I know what is coming off I will go to the for sales thread.

tricstar Posted July 14, 2014 Share Posted July 14, 2014 Yeah your heading down the right track in regards to clutch etc. I just changed from an OS giken triple , just like your quad. It destroyed more than half a dozen gearboxes including 2 OS Giken gearsets. I loved the feel of it and had no problems driving it, but anyone that just hoped in to have drive did struggle a lot!! Hopefully the sprung centre will be the difference and help the rest of the driveline.

The real NISMO1 Posted July 14, 2014 Share Posted July 14, 2014 Yeh , had a few blokes talking up their driving skills and I gave them a drive when I first got it home, they could not get it going to get into second, made me feel a bit better after my drive home from Sydney when I bought it,1 1/2 hours in peak hour traffic,F, it was less than a fun drive in your new car,haha The OS triple was an expensive exercise for you but I guess you were giving it heaps and loving it at the time My Quad is OK as a DD now with the changes I have made but from what the boys have said and what you have experienced I would be stupid not to have the clutch changed while I a having the build done. Trouble is now I have to wait to get it done Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/page/5/#findComment-7338478 Share on other sites More sharing options...

SiR_RB Posted July 19, 2014 Share Posted July 19, 2014 Don't think it's ever been bled, not in my ownership anyways Just fresh matic d in transfer case, I've never touched the fluid in the attessa system before...

XKLABA Posted July 19, 2014 Share Posted July 19, 2014 I do it every 10k, it is fairly easy to do when you have seem it done, with the power you have use Trans max Z or even RP Syncro max in the transfer case and the Matic D in the ATTESA Paul, its to do with how the spring setup works and how hard the springs are, the spline rotates inside the clutch disc with only the springs there to stop it, now this is fine if the springs are strong enough to absorb the torque but if not them the spline will rotate till the springs bind then the box takes the brunt of it if the clutch can't slip and by the time the springs bind the clutch is already engaged Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/page/5/#findComment-7344042 Share on other sites More sharing options...

XKLABA Posted July 19, 2014 Share Posted July 19, 2014 Thats why I not sold on it, cause I have no idea how far you can go with it before it becomes a potential problem, I know I feel happier with the I sprung triple in my 34 then I would a sprung one, I know I felt it with one of the single plates I had in the 32 I am very doubt full all the springs are identical, then that might be the torque rating the clutches have is referring to ? Tuffer springs or extra plate ? Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/page/5/#findComment-7344100 Share on other sites More sharing options...
tricstar Posted July 19, 2014 Share Posted July 19, 2014 So IF the springs aren't strong enough to absorb the shock, then it would be the same as unsprung? Wouldn't it? No better, no worse? What's wrong with Matic-D ? Ive never had any issues with it. Whereas when I tried some others that were recommended they didn't handle it ( boiled I think ) Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/page/5/#findComment-7344162 Share on other sites More sharing options...
XKLABA Posted July 19, 2014 Share Posted July 19, 2014 Depends how hard it hits the wall ( spring binds ), at least with the unsprung clutch you can slip it till its loaded up fully, but hitting the spring stop would be like slipping your foot off the side off the clutch pedal while its on the floor boards giving the sudden jerk, again this is just one of my crazy theories and no real proof of it and would depend on how hard you are over powering the springs Matic D is basically dextron III, not exactly same but very close, where Trans Max Z and RP Synroc max are designed for higher then normal loading like towing a caravan and stuff and while you don't have any issues with it and most likely never will I like the idea of having something designed more for what I'm doing with it Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/page/5/#findComment-7344203 Share on other sites More sharing options...
