R32 Gtr Gearbox How Strong Are They.

[GTR 400]

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.

shift off boost and not like your trying to win the 100 sprint and they'll be ok

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!

yeah. 315awkw it was sweet! for 18months did an 11.3@122

got a retune to 376awkw it exploded a week later. (input shaft gear. it haD a route six gearset)

time for me to revise my driving style.

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.

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.

it is a ticking time bomb. mine had a route 6 gear set in it. (os giken style) but the input shaft gear exploded. so yeah standar box good for id safly say 340kw. any crunching it will pop garenteed.

heaps of full on launches, about 280wkw, no gearbox problems in mine

[DRGSTR]

5th to 4th crunching pretty common?

[Bumblebee]

there are a few 10sec gtrs runnin with standard boxes around the country

[GTR 400]

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.

[Bumblebee]

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

[R31Nismoid]

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

[Turbz_13]

mine 4th - 5th crunches atmo. not always. im making 240rwkw.

[T04GTR]

yeah. there pretty weak. just broke another one. i changed abit to energeticly into 3rd. and bang. 376awkw=gearset upgrade needed. doh
