My 32 makes 250kw atw and im running a rb20 box, second gear synchro is rooted and the box whines like an annoying girlfriend in the 1st 3 gears, it is driven everyday with a 5 puck sprung center clutch.

At least it will give you a bit of an idea what to expect, i have a spare 20 box here but ill be fitting up the 25 box very soon

would a rb20 box be able to handle 230kw all day everyday??

street driving maybe with a soft clutch??

I killed one with 183rwkw RB20 and one with 183rwkw RB30 (2nd one went a lot faster with the RB30).

Could have been the button clutch and too many 2nd gear clutch drops though.. :bunny:

Gee he must be gentle with it!

A mate managed to smash one in a HR 31 with a NICS RB20 with a R34 Turbo and Mines ECU! This wasn't from excessive thrashing either! :S

Mate 2 managed to smash one in a HR 31 Passage with a silvertop and GT2530 (don't know power figures for either, but not the best track record lol).

I'd be kinda wary of them myself.

      Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.

      R33 Fuel Pump & Brakes after alarm swap

      I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?

      So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you

      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.
