I only had less then 65k miles on the car. Yeah I was running the stock turbo but I changed my exhaust to a full 3" cat back so I was running a stage 3 tune.
I will be upgrading the rods and pistons with Carillo. Going to bore out the head to 0.5 mm. Changing the clutch to the Spec stage 2. Complete rebuild of the stock turbo to a hybrid turbo. We were going to do the GT28 turbo at first but my guy was saying it won't be a fun street car. If I was planning on just tracking then he can see us putting this turbo. Gonna change out the Ex/In manifold gaskets, Oil Pan gasket, oil & water pump. I am sure I am missing other things. All in all this should be a pretty quick Mini.
I will be posting more pics as the process continues. I am hoping to have my car in about a month depending on how quick the turbo shop sends my replacement. I will also post a dyno run after I break in my motor. I am hoping all this $$$$ I am spending is well worth it.

Simply replacing pistons, will not repair the issue!
The damage to you're piston is from detonation issues, and typical in the sustained damage, so you now need to investigate further to find the cause of the detonation issue, as already mentioned, a new set of pistons, simply masks an underlying problem!

I'm betting too high of boost with the Alta Stage III tune and the wonderful insulating properties of black carbon. Too late too see now!
Even on the track I could not see the GT28 being that more advantageous especially considering all the adaptation to the engine & engine bay you'd have to work through. You'd probably have some fantastic pull from 4K+rpm to redline, but hell this isn't an engine you wind up to 8500rpm The smaller turbo on the MCS and JCW is what keep the car a nasty contender on the short track.

It's all very well replacing your rods and pistons, however, you need to find the issue as to why you're piston broke in the first place ?

There are many variables to uncontrolled detonation, and dependant on the cylinder pressure spikes and heat harmonic vibrations, will determine how a piston fails, and in this case the unsupported ring lands are the weak point on this particular hypereutectic trapezoidal piston.

Keep everyone updated on your new build though!

Why are you having difficulty, is it because you don't understand the effects of uncontrolled combustion pressure shock waves/frequencies ? Common reference to knock detection, or lack of detection, if the harmonics fall within the anti knock detection sensor/s range.
