very decent results with your car there mate.

I have a question and I guess it is more of a technical question though..

with all the talk of skyline turbo's and ceramic wheels dieing over x psi and so forth..

your's at 14psi and still going for god knows how long and according to the mag, more than 100 1/4 passes in that form..

common theory of the ceramic exhaust wheel breakage is too much boost which results in too high exhaust temps which break them.

so with the use of NO2, what effect if any does it have on the exhaust temps?

is this the reason for your turbo still living today?

also, is your NO2 disconnected in someway when outside WSID?

what sort of boost is dialed in during street driving?

thanks and all the best.

Exhaust temps actually go up with Nitrous Oxide usage. Boost spikes to 14psi on the bottle but only very briefly. Over-speeding of the turbine wheel can cause it to delaminate from the shaft - not always JUST heat related.

I don't drive around with the bottle in the car when I'm on the street and when I drive to the track it certainly isn't connected. Theorhetically I should also have the solenoids isolated with blanking jets but that sounds too much like hard work to me :D

Boost for street driving is usually your regulation 8-9psi with the EBC turned off. That's where it lives most all of the time. Off.

Thanks heaps guys, girls and pusseh boys like brett :)

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      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.
