Hey, i bought a few GTR boxes (push) and some sr boxes, thanks to the importers they gave me a heap od forks and carriers that "should fit" haha, its ok as they were cheap. Anyway, does anyone have heights of the GTR carriers so i can identify the right one, or can i use anyone with the correct height bearing? I'm converting my GTR from an extreme twin plate pull clutch to a push gearbox with a nice sprung center Blitz clutch, does anyone know the dimensions of the bearing i am meant to use with this?

Thank you

cool. well 99.9% of multi plate clutches all use the 12-14mm carrier. mesured from the base of where the bearing sits on it to the surface the fork rubs on :)

no idea what car they come from..

ps.. you must use the small "datsun" bearing. (the standard one is wrong for a multiplate., a very common mistake)

they go right up to 25mm or so for the stock clutches.

thank you, i have found on the ORC site a PDF with all the nissan numbers with there respective measurements! Also i went to a reputable clutch place here and bought a small throw out bearing as you described its very thin. I just ordered a new push slave cylinder to suit the new g box and ill dummy it up and take some measurements and see where im at, but it looks good to go atm.

Thanks

yo

just having a read threw here.

about to put my 30det and 25t box together with a nismo twin plate clutch.

measured up my throw out bearing carrier and mine is more like 22mm???

and im unsure if its the factory throw out bearing.

it came with the clutch kit that was brought brand new from a private seller..

how do you go about getting the smaller throw out bearing carrier and such

cheers tom

well it all depends, what i did was use a 16mm carrier with a 16 mm bearing (small usually like 22ish) then it was a little bit too small, so i spaced the pivot ball out 2mm. You can change pivot ball spacing, bearing and carrier.

goto nengun, they have the ORC bearings and a link to the ORC web site, on the last or 2nd to last page of the catalogue it has all nissan part numbers for the carriers. I just ordered a brand new nissan 14mm carrier and dont need it so if u want it i will sell to u for what ever it cost me (they week wait special order from japan)

the ball, short is a 14mm bar with a ball on it. the lon one is just longer. like 30mm or so. make sure you use locktite on the ball as it will leak oil if you dont.

of and the bearing is heaps smaller in diameter ie: the rubbing surfave is just bigger than the sleeve its pressed onto. where the stock one is alot bigger.

nismo use the small one.. youd be supprised how many people sell there twin plates because its to hard to drive....all because they have wrong bearing. nismo also needs a 16mm~ carrier. i used a 12mm one with my g-max3.

    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
    • I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.
