yesterday i checked the solenoid ... its dead i think .. any way .. i'v changed it with small valve i made .. to give 7-8 psi and it works perfect .. (temprory) tell i find new solenoid valve ...

by the way .. the r34 actuator opens the weastgate at 4 psi .. the valve i made bleeds some air out ..and reduce the pressure on the actuator (if any body intrested .. i can post some pic )

fazt-r33 : ... as rhett said ... on the stock gauge its normal to show 3-4 ... any way check u'r solenoid valve

If it hits 7x100mmHg on the stock gauge that means you are running about 14-15psi i think, or close to double the stock boost. You know, there are different units for pressure around, psi is just a more common unit. bar is probably used second most.

    • 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.
