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.

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
