Hello

I have read peoples results after upgrading their RB20. Upgrades like turbos and fuel pumps and others. Many times I see that their rwkw is something like 140 or 150. I have read also that the stock rwkw for the RB20 in a GTS-T is 160rwkw. So why are people coming out with less than stock and happy about it?

Am I missing something?

The factory kw rating is usually at the flywheel of the transmission not the wheels.

Transferring power from the flywheel to the wheels takes some of the engines power because it has to move the gears then the drive shaft then the axles.

For example the standard kw rating for a R33 Gtst is 183 kw but on my 33 which has all the supporting basic mods makes 181 kw *at the wheels*.

Ok

So my car is Rated a 160 kw but I get less than that at the wheels. So when people say with the R33 turbo on by R32 will make 180rwkw up too when done right, this means at the wheels correct? Kw is main, but rwkw is smaller actual to the wheels?

Yep basically right, you car uses power to spin the gearbox, flywheel, driveshafts, wheels etc.

RwKw is the power that actually gets to the ground.

So everyone here on the forums uses rwkw, its easier to measure.

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
