      Just talked to the shop. Head is off, everything looks good. They said its the worst blown turbo they have ever seen I made them promise to take more pics

      Trying to figure out what's the best way to finish up stage one of this project. Since I'm planning for an e85 tune, I need some monster injectors and a high flow pump. I'm leaning towards a set of Bosch ev14 series. My plan (if it's even possible) is to buy my pump and injectors over the next few months. I'm hoping I can add the injectors and pump, and run my apr93 tune until I can make room in the budget for a Maestro tune. Any help or suggestions on this would be helpful and appreciated.

      I may have said this to you before but you can make this work without even needing a specific file. It will not be as optimized as a fully tuned car on Maestro but you'll run at 90% of your potential on E85. The F23 flows better than the K04 but is not far enough that it can't work with Unisetting tweaks.

      The way I'd do it in my own car is using 630cc at 4bar and an inline filter. I get less than 80% IDC with 630cc injectors at 3bar on an inline Bosh 044 pump (33-34 psi in the midrange). Adding one bar of fuel pressure will supply enough fuel for the F23 with some head room. Unisettings is free and a VCDS can even be borrowed to make the tweaks. Several guys (including myself) have been successfully running on corn this way, and we have the settings needed pretty much ironed out. It may not be a good idea for a noob to attempt this but you have enough technical knowledge and support to make it happen.

      Hey buddy, yeah we've talked about it a little bit. But I guess my more immediate question would be, Is this thing going to be daily drivable (and maybe get on it a little) without any tweaking, and still on my apr tune? I plan on limiting my boost to 15psi for starters, so I might not need any headroom.

      The picture of your valve cover removed reveals a lack of maintenance, the head shouldnt be such a dark color brown. Have your installer remove the oil pump pickup tube, backlight it, and check for clogging of the screen. Cooked oil may be clogging the oil feed line to turbo, causing it to fail. The oil feed supplied with the F23 didnt fit with the cast manifold, for me and many others. So if your installer cant get it to fit, just order a new oem line.

      Not on E85, but on pump gas yes. Just get the turbo in and make sure your hardware is straight before you start playing with E85. Get your injectors and pump in, then tweak your APR file to still run on gas so you can fall back if need be. THEN start the E85 tweaking.

      Agreed. That dark brownish color screams non synthetic oil was/has been/is being used. Bad bad bad.

      I've never used anything but synthetic. But I'll ask him to take a look at the pick up.

      A clogged pickup wouldn't result in the brown staining, it would lead to low oil pressure and accelerated wear in the top of the engine. Original owner? I'm guessing by your join date you're not. lol How long have you had it and how many miles when you got it?

      Yeah, second owner. I bough it with 32k, now it's got 86k. I've had it since 08.

      So it took you 54K miles to blow your turbo? You aren't crazy modded, from what I remember? So why'd the turbo go to start with? Checking that oil pickup sounds like a good idea. lol

      I have a feeling that my super preloaded wastegate had something to do with my turbo failure

      Max would disagree with you.

      Somewhat, since preload and spring tension seems to be confused in the 1.8t world...

      What I run in abundance, and advocate for is spring rate (wastegate actuator) that is proportional to the amount of boost that you're running. The OEM actuator was designed to work around stockish boost and honestly works well within these parameters. However, once you start adding considerate boost to what it was engineered for, you introduce wastegate flap creep. The flap creep is an undesirable condition that results from the pressure on the hot side exceeding the spring rate in the actuator, and forcing the flap to open/bypass (wasting energy at WOT that could be used to create boost on the cold side).

      Preload is an entirely different thing that some people in the community mistakenly think is the same as adding spring rate to the actuator. Preloading, although it somewhat increase the actuator spring rate in a non-linear fashion, is a terribly bad idea that I always advise against. Eric, on top of having an uprated actuator, played with the preload which likely killed his turbo. Preloading is bad because it considerably reduce the amount of travel on the wastegate flap. With reduced travel (less volume bypassed) EGT goes through the roof on an already hot running turbo as the K03/K04 we have. In my cars, I never crank the preload because I know what it does (I learned the hard way over a decade ago on my Eclipse that the increased EGT from preloading the actuator is a bad and costly thing).

      Exactly, the reduced travel, not the higher/later opening point (boost level wise) is why it's bad. Eric had both, so not sure if it contributed or not. I would "preload" the internal WG on my T25 GT3076 a LONG time ago, but by "preload" I mean adjust the actuator to be as stiff as possible where I'd have to stretch it out to get it onto the flapper post. No additional springs were used.

      Was real synthetic oil used, like castrol syntec or mobil 1, or the fake stuff that's just refined regular motor oil like from pennzoil and quaker state? Did you do your services on time as well, made sure to never go past the 10k interval or 1 yr mark before oil changes?

      Oh yeah, the longest I've ever gone is 5800-5900miles between oil changes. I'd feel horrible going 10k. Ive only used mobile1 until recently. Just started using royal purple.

      Royal Purple? Seems a little overkill for oil, but its good stuff. I've read an article comparing different oils on how well they protect against wear, using a special machine that tests oil protection by applying high pressure to a bearing race in an oil bath. Royal Purple and Red Line blew away the competition, none of the other brands could even come close to their protection. Previous owner of your car may not have cared so much about maintenance and did services whenever they felt like, if ever.

      I replaced the oil pump pickup tube on my car @ 124k miles as a just because. It didnt need it, engine block, crank, and rods were still the color of cast iron. But had the oil pan off and replaced it anyways, better safe than sorry. Replaced the pickup the week before I installed my F23.

      This turbo come off a 97 Mack semi truck. Inline 6 300hp engine What I was holding was what come out of the intercooler and who know where the rest went. Oil was everywhere!!





      And Wattanty you need to find a way to fit a 6" down pipe in the TT

      Awesome! I've spent a lot of time working on diesel engines.

      Nice, this is the first time I have had to replace a turbo for any of the "24" trucks we have. What type of background do you have in diesel engine's? I know it the service and what not but I guess im asking if you worked on the hemtt, tanks, humvee, ect.
