You were warned that your motor might blow? There are many of us with nearly 50k tuned miles. I race my truck and will until it blows or I sell it. All engines have a few lemons.

Weird...its the truck torque rating and the car turbochargers.

Joewee - I was warned before I purchased the truck. They suggested I go with the 5.0.

Engineermike - When i called Ford Racing, I asked what size the turbos were, since there are 2 and they didn't know. What's your thoughts on the GT 15 in this application. I hope its better than what I had.

I'm not positive but I thought the truck bw turbos were a tad bigger than the car ones. I'd be more concerned about whether or not they'll bolt up.

I did ask Ford Racing if the engine would be a direct replacement and bolt right up and work with my existing ecu and they confirmed that it would. But then again, they had no clue that these engines had any issues what so ever!!!. When I searched for information on turbos for a 12, Borg Warner is what would come up. But no size listed. I tried to find all the issues I might encounter with this replacement and it was not existent. If i have to, i could switch the turbos from mine. I guess am the ginnin pig here. And hope everything goes smooth.

When I was looking at new trucks, I was warmed about the ecoboost issues. But being a need for speed type of guy, I didn't listened. Man I wish I would have.

Curious you are blaming Ford for this? Not to sound like a Fanboy, cuz the 3.5 has issues, but durability is not one of them IMO. What leads you to think the tune isn't the culprit?

The design changes ford made to the new 2.7 Eco are interesting and may provide insight to weak points of the engine.

Ford went with a stronger block and moved the motor motor mounts off the block and onto the lower box. Very Interesting !

Because all of the tunes are safer than the stock file. Anyone running there engine untuned is at risk of blowing. It's true I read it on the internet. Lol
