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.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
