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

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.

Dave.

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.

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..

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

      Need AC Compressor for R32

      By joshuaho96 · Posted

      Aren't these run off of high voltage in OEM applications? Like 200+V. Or at least 48V in mild hybrids. At ~18,000 BTU ballpark nominal capacity the power draw is at what, 2.2 kW? ~185A is a pretty crazy amount of amps. At 200V it's only 11A. The 70A nominal kits with up to 100A peak draw I see for stuff like classic Porsches have pretty substantial compromises like shutting off at idle and not actually managing to keep the interior cool in hot conditions because they can only output like 6000 BTU. IMO if I had to pick what high amp draw component to retrofit to these cars I would start with the engine fan, not the AC compressor. You need an ~850-1000W brushless fan, something like this: I would love to see the data but I would bet that whatever you save by running the AC compressor in a more efficient regime with an electric motor you're probably losing to conversion losses anyways. It's not really like a clutch fan where you're losing power all the time even when it's nominally disengaged and it gets worse as it engages because the envelope tracking isn't that precise.

      I'm wondering is the Toyota and Mazda "collaboration" could see that new Toyota ???G20 ??? turbo engine that they have been showing off recently into a future MX5, apparently it's good for 400hp out of the box That could easily, possibly, be much better than the last collaboration between Toyota and Subaru with the boxer engine in the twins
