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?

Cheers, Dror

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.

Looks good Gav....top stuff.

that drama with the crank got sorted i hope.

If ya want a squizz at how ours is progressing see link.

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.

    • Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.  
    • Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly
    • oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)
    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
