Hi to all i am new to the forum and own a R32 gtr and have heard lots of different advice from various performance mechanics in the know about how strong a gtr box is.

I am putting a plea out to all the real experienced owners of angry skylines to please give me some real life advice as to what sort of power they are running through these gearboxes and what they can handle if driven with some sort of decency.

My car is running a 12.4sec quarter mile and i was told that from here on any lower times with these boxes is just luck of the draw, i have a heavy duty organic clutch and consider myself a decent driver not a rev dumper of big power as some might do.

Can these boxes hold out comfortable in the mid to low elevens which is the target i am happy to achieve and will this gearbox be up to the task, any experienced advice will be most appreciated thanks to all that read and pass on any info for me.

Cheers Dave.

Hey,

I've got an R32 GTR with 270 4wkw putting it to the ground through 255 tyres on all corners and my box is holding up fine, I think that sort of power is good for an 11 pass...not sure as I havent put her down the strip yet. Putting a high quality oil like redline in your box might help prolong wear and smoothen the shifts a bit and like you said, don't do any high rev dumps.

Cheers!

On standard cermamic turbos,1 bar making 260rwkw . I have done over 200 11sec passes...mostly all in the 11.5-11.6 range. That launching the car hard on powerfc pro launch control set at 7200rpm. Used redline shockproof oil (red) and os tripple plate clutch.Didnt have one problem with the box, for 2years...drove it on the street/drag. Still in the car now, but hasnt run in 5years..mock up box for my drag car.

The only thing that is an issue in my r32 GTR box is when I shift from 5th down to 4th it will crunch/grind a little. Car is basically stock atm 208rwkw but will be pushing 300+ next week so if she blows Ill let you no. :nyaanyaa:

Thanks guys for all your replys, it is good to know that with low elevens my quarter mile target i should be ok with the standard box, has any one else achieved an awesome quarter mile time through the factory gearbox that would be an interesting bit of knowledge to obtain to see what limits some people have been able to go with the factory box.

Cheers,

Dave.

Holy Cow really 10 sec GTRs on standard boxes thats incredible dont mean not to believe but any one who belongs to the forum who has done this with the standard box please stand up and tell us haha.

My mate did a 10sec pass in mine standard gtr box. Most 10sec gtrs here in NZ are running factory gtr boxs. Most of them arnt street legal because of import laws.

i didnt really believe it either.. ive heard and read about.. dont actually know anyone who runs 10s with stock box.. but if u do.. damn impressive.. i think durability is all about how u launch and shift.. if arent too hard on the box then it should last... i guess

Generally when you get over 300-330rwkw then things start to stress a bit more than the gearbox sometimes is willing to take on.

Also original condition of the box does play a fair part in it aswell.

Stock turbo'd GTR's tend to never have issues.

Its once you head towards 340/360rwkw and thumping launches with some traction that things tend to no be so happy, and 3rd gear is common

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
