Duncan's too scared to tell everyone, but the cars going to have, at least in the beginning, chinese turbos. Yes you heard the lunacy here first, but instead of the 2530's I've ordered a pair of chinese turbos and an external 50mm wastegate. I'm pretty confident that the setup will provide a pretty good balance of low down torque and not peter out as happens with internal wastegate turbos.

A/R is .63, which may be a bit laggy, but I'm hoping that they will come on full at about 3800 and boost solidly right through to 7500. I'm a big fan of smaller turbos, but if this doesn't work, I'm going to have a tough time holding Duncan back from the 3L conversion.

I intend to get the turbos properly balanced before going ahead just to make sure, but if they come in alright, then they are going on!

Let the flameing begin!

we shall see how the yum cha turbos go. personally i'm hoping they will be a winner but the 2530s are going to be hard to beat for this application.

unique1, can't remember exact figure but it was under $5k. its unregisterable, I think it was rejected for sevs compliance so worth nothing except parts....or as a cheap race car :ermm:

lol nice turbo choice :geek: 5k for the car complete thats crazy cheap, any ideas where to find similiar bargains? ive searches my105.com etc and nothing :huh: im looking for a race only one as well, im still deciding between gtr and gtst though, its a tough decision.

yeah mate, cheap unregisterable cars come up pretty often, I posted a $9k R33 GTR up about 6 weeks ago. Just keep an eye out, its a buyers market so you can get some real bargains if you aren't in a rush :wacko:

Even cheaper still is to buy someone else's already prepared car - as far as GTRs go the place to look is old Targa cars. There are at least 20 targa gtrs in aus and only about 5-8 are still racing. The big cost in building a race car is not the shell, its the cage, suspension, wheels and tyres, motor, fabrication to suit, recoing driveshafts/tailshafts/diffs/gearboxes/xfer cases you get the idea

Yes I do need that light.

Even better bring us the whole bloody car and we can get it back out on the circuit this year sometime.

Id try the china turbos if your happy to do so, why not!!

2530's would be a good option.

I wouldnt rule out GTRS' either but it does make the thing a bit harder to drive on tighter circuits.

Mark, you know very well his addiction to breaking perfectly good motors :banana:

Yeah, I've witnessed, been involved in the event, caused at least 1, and helped him take the motor in and out more times than I can count. We've done it so often that a bunch of plebs like he and I can take the motor out in under 2 hours and put it back in in around 3. He's even got to the stage where he can do the contorted starter motor bolt dance and only need about 3 skin grafts for his hands. :banana:

hi

we did a flywheel and clutch change in the gtr at the IPRA nationals last year in 32mins (at the track on the ground)

engine change at last round 6hrs drive in drive out, thats changing everything onto another short motor as well.

Damn it, now you've set me a challenge Dave! Have to wait til Duncan breaks another motor to try again. Should be sometime next week :P

Do you guys drill out some holes in the back of the sump so that you can get to the 2 10mm bolts in the rear main seal girdle? I've often though of making a couple of holes in the 2 winglet areas so that I can get a 1/4 drive socket in and remove the bolts without having to remove the gbox. In theory, you should be able to drop the sump in car and change a spun bearing, blown diff, or in my case swap my sumps between standard and extended.

Haha dont worry it will be coming around for sure :P still waiting on the motor...

I think you would destroy the spray gun nozzle in a matter of seconds, most sandblasting kits are only $30.

Wouldn't destroy it, wouldn't do anything at all except maybe clog it permanently. Spray gun is far too small to allow anything as big as sand through it. As ben said, sandblasting kits are cheap. You need a decent compressor, but the kit is really just a container and a gun. The booths can be costly, but if you are not doing it much, then you can just wear a mask and forget about collecting the used sand.

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
