woah! im on my uni breaks from mechatronics eng and physics still haunts me here LOL.

please dont make me get my books out.

lets put it this way, cars are approx 20-30% efficient. And in the worlds of todays technology, its not how much power u have, its how u put the power down that moves the car. i think we all can agree on that. just remember this..... NISSAN have NEVER overrated their power figures in performance cars.

sure the car will get from 0-100 in 3.3 but its doesn't necessary mean it will last more than 10 launch.

almost of japan workshop have been delivered their gtr's just give them a week or so to break in the engines before serious thrashing can begins on the dyno's.

force and energy ARE different things. that's why they have different names!
Force is just energy doing something... everything is energy, you, me, the tree, the rock, everything, yes. Even between the land and the ship.

If an unstoppable force meets an immovable object then the universe explodes.

The wall does get hotter, the person gets tired. Energy is conserved.

from the well respected physics text, "Yuri the Guru's guide to the universe"?

Force is not Energy doing something. You've got it back to front. Energy (in physics) is a measure of Work done by an applied Force.

If an unstoppable force meets an immovable object then the universe explodes.

The wall does get hotter, the person gets tired. Energy is conserved.

who said anything about an unstoppable force? universe exploding? OK then...

energy is always conserved within or between systems. no argument there, but that's a different thing all together. Forces can be applied but do no Work with no Energy transferred, and that's what is happening. Force spent doing nothing = no Energy output. go lean against a wall for 5 minutes - you are applying a Force to it, but you won't get tired and the wall won't heat up from the force (ignoring the conduction of body heat - let's assume that the wall was at body temp beforehand). By leaning on the wall and imparting a Force, you've created a Potential Energy. you haven't transferred any Energy to the wall because you've done no Work on it.

i guess mines and mcr didnt get that msg? didnt they take there cars straight from nissan to tsukaba?

GT-Rs were heavy enough as it was; in tighter corners their weight could really be felt and could prove to be quite tricky to handle in some situations (mainly in a series of tight corners where the weight of the car is shifting from one side to the other and/or front to rear; and also when entering a corner hard under breaks, the front would could push wide because of the weight).

Even though Nissan seem to have engineered the car very well, imagine how much faster it would be had they kept the weight down.

Bear in mind that Nissan have dumped their inline 6's. They are poorly balanced (weight-wise) compared the the VQ & VR engines and that's why they just want to understeer all day through tight bends.

Look at some of the JGTC examples: the GT500 Supra using an inline 4, or the R34 GTR with a VQ rather than an RB. At speed the more even weight distribution speaks for itself performance-wise. Look at the damn R35 gearbox. It's under the boot!

That said, the R35 is a bit of a fat sh!t.

yep the new engine, all alloy block , but without cylinder liners!! instead a o.15 plasma sprayed bore which they must be concerned about & want to keep an eye on i would say.

i will almost guarantee that one of the first rebuild mods will be to put liners in the bores. mind you it will effect weight balance by a few kilograms (but then again so do i)

I'm saying trim the weight back 100Kg or so and you guys are reading build a stripped out racecar the size of a lotus elise. :)

Are previous GTR's too uncomfortable and compromised? They weigh considerably less than the R35; yet i don't hear many complain about their structural integrity or the interior space. Nissan could have easily kept the weight of the car down; the only reason i can see for them to avoid doing this is cost since lighter weight and higher strength material would cost more. Bear in mind the new engine is probably a lot lighter than the RB series and i'm guessing most of the components in the driveline are also lighter and stronger. Which brings me back to my original question, where has the extra weight come from?

How the F&% do u guys no this kinda s$#%?!?!?! F%$# me... goddamn physics and energy and universes exploding and shit.. its just a car, a car that was never intended to be driven by any of you its a cruiser. The only reason its fast is for cred, so that people will want it, desire it. The only reason it carries the GT-R badge is for the same reason, desireability and credibilty. Its all marketing, Carlos Ghosn is a genious and he is in the progress of turning nissan around from bankruptcy. The name is just a name, this is not the GT-R of old, its simply not, it carries different design philosiphies. Its fat cus the target audience nissan has aimed the car at wants it to be like that. They want the comfort, hey want the awesome sound system and the sat nav and the heated seats and all that shit.

Excuse my spelling i never finished high school.

no such thing as an R35

you might be talking about the V35 ?

ummmmm okkaaay. there was this small car release recently. you may have heard of it. something like Nissan R35 GTR?!?

    • FWIW, as well as a basic immobiliser/remote unlock (all basic units give you those 2 things), I would also install a 4g tracker in any car I cared about. Just hide it anywhere that won't be found in a rushed look and preferably get something with a built in battery backup so it stays online for a while when the battery is removed or flat While its not a car, when our car trailer was stolen in that den of crime Sydney about a decade ago, the cops were watching from the bloke's neighbour's lawn within about 2 hours until he started swapping the plates and putting up the gumtree ad.   Obviously it is still not undefeatable (eg parking it up for a few days somewhere without sky sight) but it greatly improves your chances of getting it back quickly and with less damage
    • Instead of magic keyphrases I wonder if something can be done with auto complete. Similar to how user names are handled already. When you type '@' and follow with letters, it'll search across all usernames. It might work to have the same for forum topics. Some key to trigger it and then text search across all thread names and it'll insert the name and URL when pressing enter.
    • Hmmm.... It's actually a bit weird. Here's the key bit of the diagram. I've circled what I'm pretty sure is the high beam indicator on the cluster. It appears to be just in parallel with one of the high beam lamp globes. Meaning, that however the high beams get lit, the indicator should also be lit. So there shouldn't be any difference between being on normal headlight main beam, or just flashing. I've followed the physical diagram (which is not so easily summarised in a single snip, so I didn't put it up here) and it agrees with what you can see here. If you struggle to follow this crap....let me explain some of it. I always struggle when I first look at this - even though I have looked specifically at this more than once in the past. We'll start with the flash. The flash is triggered by pulling the dip switch back, right? That is indicated on the diagram by the P position on the switch block labelled "Light SW", on the RHS of the snip. The bottom-right most terminal is connected to ground. That's that wire line going down to the bottom. The next terminal up is connected to the bottom terminal when the switch is pulled back. That provides ground to wire LA33, which is connected to the coil of the relay in the middle of the snip, "Headlamp relay (2M)". That relay always has power on the other side of the coil, from fuse #19 above it. When that relay is triggered, the two main headlamp fuses #32 & #33 above feed through the relay down onto wires LA31 and LA32, which are connected into the wires that go to the main beams, LA04 and LA06. The cluster indicator is connected to LA32 also. When the main beams are on normally, the light switch ("Light SW" again) is in the M position. Power comes in for the left and right sides on LA34 and LA36, via the other light switch (the one on the binnacle, called "Light SW (Instrument)" on the diagram). Obviously that switch needs to be in the 2nd position, because that's headlights. 1st position is parkers. The same main headlamp fuses #32 & #33 feed through that switch, out via LA34&36 to the stalk switch, and of out of the stalk switch via LA04 and LA06 to the headlamps. From there, it is no different to the flasher version. I really don't know why they bothered with the flash relay. They probably didn't want to add another contact in the stalk switch - but I'm damn sure that's what I would have done. Just reverse the order of power feed, so that it goes from the fuses to the stalk switch first, and add another contact for flashing. Everything would have worked just the same, but less complicated. /bitchrant
    • I think the solution Pac posted in the other thread is the way to go with the top screen; I have an ADM Q50 and I only use it for 2 things: 1. Reverse or front camera as triggered automatically by Reverse selection or the front sonars, and you can also call up the front left (or front) camera when parking by hitting the camera button on the centre console if necessary 2. Navigation. I can assure you that getting hold of a 10 year old nav system is utterly useless. The ADM system still has Inifiniti dealers marked (always give me a good laugh), is missing all new freeways, uses fixed speed by road type to determine arrival time, no traffic/re-routing, no speed cameras, no user reported cameras etc etc you get the idea So, Pac posted in the other thread about a box that plugs into the USB C and gives you full Android OS to run whatever modern/connected nav you want on the top screen, and it still automatically switches back to function 1 above when required because it runs within the head unit. The other modern alternative is the latest version of the Tesla screen like this:  https://www.aliexpress.com/item/1005007511322502.html?spm=a2g0o.productlist.main.25.33cefEZifEZibq&algo_pvid=cdae429c-aa8d-437f-a436-c727fee85461&algo_exp_id=cdae429c-aa8d-437f-a436-c727fee85461-12&pdp_npi=4%40dis!AUD!2181.36!1265.19!!!9834.81!5704.20!%402101c71a17362022663526105e36d7!12000041077843545!sea!AU!163137612!X&curPageLogUid=F9811g8oqx5H&utparam-url=scene%3Asearch|query_from%3A But I haven't looked into whether it is compatible with Australian 4G bands yet so it may require a separate 4g dongle to provide data
    • In the 32 race car, I basically run what Gary told me and it is lovely across a range of conditions which is what I needed. I've got revalved bilsteins, adjustable solid sway bars, adjustable bushes all round. Just looking at Neil's R33 GTST and it has pretty much the same on board, Gary Bilsteins, Selby/whiteline sway bars.  Gary knows suspension generally and these cars specifically very well across street, street/track and track only use and gives a very well balanced set up. Just be aware his preference is for light springs and heavy sway bars, there is another school of though (eg MCA) that prefer lighter swaybars and heavier springs/shocks. The evo I raced had that setup and it was also very nice so there are multiple ways to skin cats.
