I did mine with a bit of help from ppl on this forum - do a search and you should find more info. The hardest bit is to find the O2 sensor's signal wire - you either need accurate ECU wiring diagram or top quality digital multimeter - look for the fluctuating voltages...... Anways, do a search !!

ok... easier... never put the wire on out in the engine bay... cause it will deteriate... plus there is voltage drop inbetween the O2 sensor and the ECU....

Do what i did... Goto the Apexi web page and go to the turbo timer manual.... in there it has a printable diagram of which pin on the ECU the O2 voltage input is... then just splice that wire and solder on.... As the apexi TT has an Air/Fuel ratio function...

Trust me... you want to be reading what the ECU is reading not what the O2 sensor is actually putting out.... For tuning purpose's

      RB20DE NEO smallbox clutch.

      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.

      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.
