Gearbox & Clutch

[265kw at the wheels holmes]

hey guys

i've got an r33gtst with 300kw atm but will have 400kw in coming months.

what do a do bout gearbox and clutch?

can a r33gtr box be modified to suit gtst and handle the power or should i be getting straight cuts? for a clutch i was thinking bout a nismo twin plate?

is this the right path?

cheers

stick with the 5 speed box you have, but i would upgrade to an OS GIKEN gear set. or a ppg helical 1-4 dog gear set.

os giken is priced at $4700

the ppg dog box 1-4 is $6500

and if you wanna do it once and never break anything (itll be very hard) then you can go the full 1-5 straight cut dog box from ppg for $9700

RB25 box is basically an rb26 box without transfer case... it's just as tough...

I'd stick with it and if you manage to break it upgrade to one of the above...

Having broken a box myself (350rwkw)

I would suggest PPG or PAR.

How hard did you drive your car??

just wondering if i should start looking before i brake mine...

i thought they could handle a bit more power than that..

My cousin has a 400rwkw R33GTST with standard box!!!. Has been driving it with this powerfor 4 years now, eastern creek plenty of times countless amounts of insane burnouts, hard driving and still holding fine, they are a tough box especially behind a rear wheel drive car.

As always if you are brutal and slam gears in like your Fangio on a mission all the time anything will break eventually.

Really i wouldnt worry that much dont fix it till it breaks, then add a gearset but i think you will find it will take more punishment than you think.

My 2 cents worth.

thanks guys the advice is much appreciated. what bout a clutch?

[Mr GTR-32]

Do it right once either a OS Giken twin plate which will hold 400rwkw as this is what my cousin runs and has that power and no probs yet. Or i guess a triple plate but i have heard these break gearboxes as they dont have a sprung centre but not 100% sure about this.

Jim berry clutches seem good but im a brand man and just like to trust good quality Japanese products.

I just put an ORC 709D in mine...

It's a lot better than expected... holds well very light peddle a little bit grabby but i think it'll be easy to get used to...

HKS GD max twin plate.... best clutch ive ever used so smooth nice take up and not jumpy very highly suggested

Its not the gears that broke, just everything else around them
