The 2020 motors have steel pistons now too. And they utilize a 1/2" longer connecting rod since the wrist pin eye was moved on the piston. So I wonder if anyone will make the 2020 rod in the aftermarket so you could run a 2020 steel piston? That would be interesting to see.

Haven't heard of that yet, they are doing a hybrid kit too, moved the wrist pin location for better crank angle.

We looked into them, don't think they were out yet . My machine shop is going to port mine, I'll decide later if it's worth going to Odawgs

Odawgs have been out for quite a while.

I wonder what the breaking point will be with the stock 2020 short blocks? On paper they “look” to be a very cost effective upgrade.

wondering this as well.

I heard the oil pump is external to the block now too on 2020s

I'm more interested in their cooling capabilities. Ie radiator sizing

I figured there had to be someone who dropped the 11-14 kit it with a build or when they swapped around turbos.



I've been quote happy with my 2015, just thinking of giving the OE turbo a mild mod/rebuilt figured with all that stuff off.....why not go a little deeper.

I bought a set for my 2011. Turbo started surging/fluttering under steady throttle up a hill with or without a trailer at 52-54 mph just like it's laid out in TSB 11-12-14. So while I'm in this far replacing to an updated '14 turbo and WW2 (make fun of me if you wish) I was going to do the studs and manifolds for reliability after hearing about them being fairly common to break and hopefully some performance (wasn't too much more expensive than stock replacements). I asked BD about what to expect and got a nondescript:
"Our manifolds improve on the reliability of the Ford manifold, while improving the radius’s from each cylinder."
It will be mid June before I get them in the truck but they look good in person. I can let you know more after install. I don't think I will be able to pinpoint specifics on performance of the manifold upgrade though since I have more changes going on at the same time.

The crank gear still from the looks of it, looks the same though.

I know, right. Youd think they have learned by now.
