anyone else here of an R35GTR from sydney that has lunched an engine?

Apparently lost the top of a piston & has damaged the block & several rods.

If this is true, someone has blown, literally, a lot of money. I can see the Nissan official line now..."Sorry; no warranty on grey or personal imports...". Maybe the thread on 35 engines in this section will heat up even further with ideas! (LTS Jayce now keeping one sceptical eye on the 'For Sale' section, LOL)

I second that....

This does not bode well for Haltech's reputation...

I dunno. It depends on what they were doing at the time. If they were pushing the envelope, at least they now know where the limit is and what the motor doesn't like.

"Blowing stuff up and then pegging back the next one a notch" is probably a bit more popular a tuning method in America, given what I've seen with VQ35DE modification (it probably explains why Edison is considered their greatest inventor). A lot of manufacturers will stress test their mules and wait for something to break.

For example, Nismo found out that the conrod pins in a stock V35/Z33 VQ35DE could only handle around 7200RPM before they started to stretch, and they'd instantaneously snap at around 7800RPM. I can't see them figuring out those numbers without putting some pistons through some heads. It was the Americans who were probably the first to figure out that out the bottom end will only take around 300rwkW before the conrods snapped if you opted for non-natural aspiration, usually by aerating the side of the block.

Assuming they know why it failed, Haltech will be one of the few tuners that do. When it boils down to it, their GT-R is a test mule as well. Their car was never going to be sold on to a customer or be used as a daily driver.

From a regular person's perspective, it's better that they learn on their own car rather than a customer's. It's just unfortunate that's it's going to cost them a bucketload to get a new engine.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all

      300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
