He admitted he raced the car. He modded it a lot and drove the snot out of it and it blew up. Big surprise.
But to do all this to a LEASED car is beyond stupid. Reading the thread it seems like he might have learned though from his $26K lesson, vowing not to mod the car again.

It was "just" an ECU reflash on a leased car. So returning it back to stock would have been easy after the lease. Too late now though

Yeah, you're right. Only 144k on the odometer of my Supra (with the original turbos pushing 19psi) when we had a little fun on a deserted road coming back from the Dragon...imagine if they weren't so tired!

...BTW it wasn't exactly unheard of for 2JZ-GTEs to give up when the stock turbos boost were cranked up and the cars were driven hard. Was in common? No. But so far it has not been common for 335is to give out either... we're talking about one case here and possibly a handful of others that are known of in total.
Even with a downpipe, it's really hard to kill the stock turbos unless you do something mean to them like spray nitrous.

Skater, As to the leasing issue:
First off, it is different because the new hardware/software BMW is running will know if you plug a piggyback on the ECU while leasing it. It was not a engine flash. This was a piggyback to the ECU. There is a difference. If they catch you doing that you are in conflict of your original lease agreement. They can force you to buy the car at that point or pay significant fees since it wasn't your car to mess with based on their paperwork. The lease agreements say the car is not to be altered at all like this. Case in point is how will they CPO a car that has been tracked the hell out of after 3 years with a ECU that is altered. If you don't know the difference than you don't read your lease agreements closely. BMW won't let you mess with the ECU at all anymore. They track fuel mapping, boost psi and air/fuel mixtures. Anything out of the ordinary and they can red flag your car. It has happened and it will happen. If you pay to play than you better be prepared to pay up.
As for the overheating. I have never had an issue with my car overheating when it was stock. Not a single issue and I drove it hard in Vegas Summer. The first year of any new car always has a few glitches. This is no different. This engine is outstanding though as a stock factory engine. If you have not driven a manual 335i than I suggest it. The hp and torque ratings may be close to a IS350 but driving it feels a lot different. You are comparing two different animals or apples and oranges. Lexus makes sporty luxury cars. BMW makes sports cars. They worry more about how it is to drive the car. Lexus worries more about what the inside looks like and how the navigation works. They both good cars. I have owned both so I know.
BTW, an NSX engine is a great engine but it costs a kidney or two to get the hp out of it. That car needed a bigger engine to start with in 2000.

The tone of your post tells me you are a BMW hater and that's fine. This is a manufacturer specific forum and there are bound to be ignorant people. You can argue all you want but no manufacturer is immune to unforeseen issues. Think about how many Tacomas, Toyota is buying back right now or how many engines Toyota has replaced in the last few years under warranty due to common issues. BMW drivetrains are very durable and I'd have no qualms about owning an E46 M3 after the warranty has expired.

... However the reliability of their high powered model was always terrible, at least initially. Maybe they fixed these issues in the following years, maybe they didn't,s its debatable, but the fact that they initially shipped with these problems tells you how poorly BMW engineers and tests these engines.
You can keep saying it, but that won't make it any more true. I've already been over each issue you cited and you failed to backup the statements about the current M5 V10 at all.
You're right though. BMW doesn't test their engines at all. BMW Motorsport isn't located at the Nurburgring and Sabine Schmidt doesn't drive M5s around the Nordschliefe 200 days a year.

It's impossible to blow the stock turbos on the 2JZ in a Supra if you leave the cats on and completely disable boost control. AMHIK. You won't make more than 19 psi though.
Even with a downpipe, it's really hard to kill the stock turbos unless you do something mean to them like spray nitrous.

I don't get the whole "doing it on a lease was stupid" argument. Whether the car was leased, owned, borrowed, stolen... what ever it was, the results would have been the same: $26k down the drain.
It was "just" an ECU reflash on a leased car. So returning it back to stock would have been easy after the lease. Too late now though

I'm pretty sure thats not from overboost or a BOV. I think something went inside and shredded the turbo.

Well, and this exactly why I said that BMW 3.0tt isnt well engineered, but rather overclocked. See, 2JZ wasn't overbuilt, it was engineered properly to handle twin turbos, as well as NSX engine was engineed to handle 8000rpms, unlike past gen M3's engine.

It's of no surprise that the 335 ended itself, we now live in a period where car manufactures are not building cars like the company's they started out as, car are built for profit and to achieve certain numbers only to better other makes, the supra was a heavy duty engine, the 335 can't compare to that, why anyone would lease a car and put a piggy back and anything else on it that is not backed by the manufacture is just odd, if you have 26k to replace the engine, turbos and piping you could have done some other stuff with that money, funny how the guy no longer wants the car, if I blow an engine up and spend 26k I'm driving the car
