Also on regards to spilling the tuners info...
Just so everyone knows I am hesitant to release the tuner's info since there is at least 2 other theories running around and I don't want this to turn into a bash fest.

Theory 1: Faulty fuel pump which caused the car to run lean.
Theory 2: Boomba was testing a product that caused the car to learn some bad numbers, ecu was never reset and car went straight on the dyno and blew up.

Without anyway to gather some of the data it's all just speculation anyway. The key is to learn as much as we can from an expensive mistake and move on.

Note, I'm not saying this with any specific knowledge on the FA20, but all of the DI platforms have dealt with this problem (VW, Mazda, etc.) and I'd be surprised if there aren't higher volume options at least in planning...
I haven't seen anything and I have been watching very closely! I am grateful for your input as I am learning as I go at this point!

That really sucks and I am sorry for your loss. It's a very heartbreaking thing to have to experience financially and emotionally.

Gahh that sucks man, I'm sorry for your loss. I'm putting mine in the shop Friday to have a DW 65c installed and to get a protune. Videos like that scare the ***** outta me.

I have to say you seem to be taking this extremely well. It would be helpful to figure out what happened to see what other people need to look out for; this seems like it was a fairly standard stage 2 setup, and it makes me concerned about going stage 2...

Getting pissed off and angry will close doors very quickly so keeping a positive attitude can go along way especially in a messy situation like this.

I though it was pretty standard as well! I am really hoping we can get to the root so others can learn from my mistake(s), I wouldn't wish this upon anyone.

Since you pulled the block was there any noticeable carbon build up on the back of the intake valves yet?

Curious why did you go such long oil change intervals? On a turbo car that's way to long, I'm at least every 2,500-3,000 max. Have you considered the IAG or Outfront Motorsports FA motors?

I didn't check myself but I will contact P&L and have them take photos. I don't know exactly what would constitute as noticeable but now would be a great time to check. Car did 45 mins of stop and go traffic 5 days a week for a year and half so now is a great time to check! Thanks!!!

I followed the intervals that the Subaru dealership put inside the car always trying to show up 500 miles early. Car never showed signs of burning oil and I always checked it before I took it in and when it came to see how much they put in and how much I had used.

I did but I am going with P&L because one of the guys that works there has similar mods, and a ton miles on their built block no issues. I also live 6 mins from them so if there are any issues they are just a short tow away and have them fix it. They have a great rep for building subarus and have been around since 2001 so it just makes sense.

Almost looks like it ran really lean and hot since all the spark plugs have basically melted or broke. That or severe knock on all cylinders.

That could certainly be part of the problem. I really appreciate you sharing your experience.

Is it that bad to floor our cars under 4k rpm? If so why? I don't drive my car hard, but if I'm going to gun it a little it's usually under 4k rpm, that's where we get the most torque, after that it seems to level off.

Just wondering. Thanks.

I would never floor (WOT) my car in the upper gears (5th/6th especially) under 4K and would just downshift.

I actually like rowing gears so for me it has never been an issue. I don't even recall ever going WOT in 4-6th gear in any car I have owned under 4K rpm.

And holy crap how fast are some of you guys driving if you are WOT in 6th gear well above 4k RPM? That's not a speeding ticket, that is probably prison.

I do, my goal is 400/450 on 93 and 500 on e85 so a new turbo will be in order. I'm literally getting married in a little over a week though and my wife to be has given me the thumbs down on a new turbo kit in the forseeable future although I have other plans in mind
Hahaha, happy wife happy life right? Congratulations on the marriage as well! Maybe she'll come around in time for some Black Friday sales

Will keep an eye out for your inevitable build thread so I can possibly follow suit (minus the blown engine, no offense )
