Big end bearing is exactly what happened to my friend engine. Cloc cloc noise ect.
GT86 also fail like that when the oil pump get blocked by gasket paste. Engine starve oil and big end die.
As a result, I really don't think GRY has oil pressure issues.
Cylindre 1 going boom however really shows that you can't afford any bad tuning / fuel or else a bit detonation may happen suddenly which will catastrophically destroy the engine.
NB : If you put 265 slick on the car it is another discussion obviously
@ninjan00dles are there a lot of failure in the US? There's been the two catching fire but after that ?
The general consensus on the first fire was that owner was trying to get an insurance payout... I don't think that was a legitimate factory issue (in my opinion).
I personally know the 2nd fire owner. I don't think that was a factory defect either, although it was a Cylinder #1 failure. Not my place to say anything more than that. The owner is pretty responsive if you reach out to him. He bought a new Morizo after that incident and runs the full 555 Engineering Cooler Package now, he's been doing a bunch of track days since (including 2 with me) without issue.
Beyond those fires I think I know of 7 other engine failures.
1 money shift on the street (ecutek tune)
1 money shift on track at Thunderhill, California (stock I believe)
3 random failures on street (all ecutek tune)
- some kid on facebook doing WOT pulls on the freeway
- smeedia / youtuber
- youtuber who had a history of a poor tune
I think the above are probably from poor mods/tune or user induced. Also Youtubers are sponsored by aftermarket vendors and have an incentive to break things for content... Unfortunately GRC has attracted a lot of these types in the US market.
The below were both Cylinder 1 failures and I consider a little bit more closely. They both had Oil Coolers and were prepped.
1 track failure on the East Coast (Ecutek tuned)
1 track failure at Thunderhill near me (Ecutek tuned)
Just my 2 cents (pence/yen/euro) - my understanding is early software builds of Ecutek were not great (which is discussed on this forum) and I think its early limitations led to a lot of poor outcomes in the US market. US tuners were either not up front or uneducated about the risk early users were accepting. Overseas you guys tend to go to standalones which are a more robust solution.
On the other hand - it also my understanding, that the most recent Ecutek overhaul was a substantial improvement. So this isn't meant to bash Ecutek, I think it will develop as it has on other platforms.
