So I'm new to the group, and was curious. I blew my ecoboost engine yesterday. Not sure how. My wife pulled up to a stop sign, went to accelerate, and heard a loud pop then oil everywhere. I know engine failure is common in the first 2 years of ecoboosts. And I'd rather not have the issue again. What would I need to do a 6.2L V8 conversion? I can buy a 6.2L cheaper then an ecoboost. Would it be a bellhousing, wiring harness, ECU exhaust stuff, intake. What else? I have the 6r80 transmission. I also found a 2014 3.5L ecoboost, but I think It would be fun to build a Raptor clone. Thoughts?

The failure rate of the f150 ecoboost is still only around 1%
That being said I too had my engine replaced. I don't think I could deal with the slowness of the 6.2 after having a 3.5 ecoboost. Sure the spec numbers are higher but the torque curve of the ecoboost can't be beat. And tuned, well there's no comparison.

I think you'd be looking at some pretty good work in modifications to make it work though.

I would rather hunt down a 6.2 and buy it than attempt that headache.

It would be a hell of a lot less headache to swap in a replacement 3.5TT than to try and swap in the 6.2......unless you're thinking about supercharging/turbocharging the 6.2 (they have kits for that). Lol. The 6.2 is a good engine, but I think it would be a long downtime for your truck. 3.5 for a 3.5 should just be a couple days at most.

Although I remain delighted with my 6.2L (yes, I did drink the coolaid of long-term reliability of larger NA V8 displacement vs 6 cylinders on steroids), no way I'd consider that swap...

What year is the truck? Is it out of warranty? Seems weird it would just die, something must have been a bigger problem. Was there any issues with the inter cooler and not having the drain hole drilled?

It's not an impossible swap. The best thing would be to start with a wrecked 6.2l truck and just swap things over.

Was the 3.5 tuned?

It's a 2011, out of warrenty, I didn't drill the hole in the intercooler cause I was told I live in an area it's not an issue. I had driven it on Saturday and it ran flawlessly. So I'm not sure what the issue was. It was maybe 200-300 miles over what the sticker said for an oil change but it was all highway miles. Synthetic oil, premium fuel. So I'm not sure

I found a 6.2L engine out of a 2011 super duty, but it's gonna be a while till I can do anything that's why I'm interested in the swap. Me and my wife really want a Raptor. But as far as the engine goes, it was bone stock except a CTS2 chip that was used for gas mileage. It was a highway truck. We took my wife's car anywhere else
