Well after a quick visit to Perth I'm back in the land of Trabants and Ladas. For those I missed out on catching up with in Perth my apologies.

I would like to send thanks to Ant, Hanson and the Xspeed team.

As some of you know, my build-up has been long and drawn out stretching over 2 years now. The past is the past, but the important thing is that the work and the dedication that Ant Scali put into my R is certainly very much appreciated and definately beyond what would be considered "just doing his job". Likewise the build-up pics supplied by Hanson and Jamie along the way and the regular emails and updates were very much appreciated.

Some may accuse me of being a "cheque book tuner", but unfortunately when you live and work in another country you either give up your dream or you rely on others to help you out. All I can say is that it wasn't a cheap dream to live, but the outcome has been well and truely worth it to me. The torque, response and braking package that we've managed to put together brought a smile to my face every time I drove my car over the last couple of weeks. There are a few small "tweaks" left to do (slight revision of intake cam specs and more work on cam timing), but essentially I've got the R that I always wanted.

To the other workshops (particularly Ken at Hyperdrive and Roy at C-Red) who gave unbiased input and advice along the way, thanks also.

Cheers

Gav

I think he did thank Jamie, moron.

Anyways, great to see your car finally out at the track day Gav. The car is just amazing.

Can't wait to see what time this puts down with an upgraded box.

Great to hear that the car is back on the road Gav. I bet it will be hard having to wait untill you come back to have another drive.

Did the bridged manifold fix the turbo shuffle problem you originally had with the GT-RS Turbos?

Hi Dror

the bridged manifolds certainly did reduce the compressor surging or "choo choo train" effect, however it is still present at neutral manifold pressure (i.e. sitting enough boost to counteract engine vacuum).

To be honest with the much torquier engine, it is an area of engine load that really isn't used that much anymore. Highway cruising is now very easy off boost. Spool-up (unless in 5th gear) is generally fast also and you pass through the "shuffle zone" pretty quickly.

Have to admit the extra torque and short diff ratios makes you pretty lazy around town as generally I only use 1st, 3rd and 5th gears now.

Thanks Paul - have certainly been watching your progress carefully.

I'm still in a couple of minds about how good the GT-RS terbs are compared to the 2530s. I did a back to back drive with an R33 running a Jun 2.7L kit and 2530s. Although the dyno graphs showed the 2530s coming on earlier, the real world driving comparison between the 2 was very similar. The GT-RS terbs certainly seem to respond well to high boost levels. Next step will be to revise the inlet cam (change to longer duration 272) and play some more with the cam timing. Rev limit is still set fairly low to 8200 for the moment, however there is probably no reason why this can't be lifted given the supporting hardware.

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
