So I've read that the 2018 f150's have bigger turbos, can anyone deny or confirm this?

From Wiki:

[h=4]Changes from previous generation[edit][/h]The most prominent change is the addition of port fuel injection, while keeping the direct injectors. The port fuel injection was partly added due to the fuel output needs on the 3.5L HO Raptor engine, but also has several benefits for the 3.5L EcoBoost. It will prevent buildup on the intake valves and keep them clean due to fuel passing over the valves. Under certain engine conditions such as low rpm and low loads the high pressure fuel pump and direct injection system will turn off and the engine will only use the port fuel injection, reducing efficiency losses due to the HPFP. Both systems will operate at cold start, which will reduce emissions that direct injection suffers to due to cold cylinder walls and lower fuel atomization.
Turbocharger changes include electronically actuated wastegates, turbine wheels now made with lighter Mar-M-247 super-alloy increasing responsiveness, and the same 51mm turbine wheels but with sharper vane angles allowing boost to be increased by 2.5 psi (0.17 bar) up to 16 psi (1.1 bar) max. The turbochargers continue to be supplied by Borg Warner.
The camshafts were made hollow for weight savings, along with the addition of a roller-finger follower valvetrain. The compression ratio was increased from 10.0:1 to 10.5:1 (except on the 3.5L EcoBoost HO for the Raptor, which remains at 10.0:1).
The engine also features auto start/stop, which decreases emissions during city driving by shutting the engine off in extended idling periods.
Overall the engines is also 4 lb (1.8 kg) lighter than the previous 3.5L EcoBoost. [SUP][71]

That's good data, but the 17-18 3.5 has a turbo difference with both being gen 2 engines. I am not sure on 2.7.

The 18 vs 17 regular truck has a good bit of difference. The 18 raptor has about a 1.5 mm larger compressor vs 17 raptor. All turbines appear to be the same but don't quote me on that.

So it is confirmed the first gen and the 17 have 51mm I think, does anybody know the size of the 17/18 raptor or the 18 3.5?

Not worth the work and money to switch from 17 to 18+ turbos. Retrofitting gen2 to gen1 is NOT something I would say most people will know how to do. It’s a lot of work and expensive, unless willing to pay someone who knows and can make all the adapters etc....

The 18 turbos do give you another 4-500 rpms of usable powerband at 17 psi without overspeed and also pay big dividends if you operate at altitude. I will be testing this very thing soon.

For a shops labor at one day its 1200 bucks installation probably plus displosal and new tune, oil coolant, etc. then you have to buy a oem core which is 1200-1250 shipped plus the $500 core you’ll get back. $150-250 in gaskets and shipping back to ford, disposal fees, it’s a ton of lot of money for 50 rwhp if swapping from 17-18 or 19.
Think about it:
If going updated route, that’s almost like $2500-$3000 bucks soho to nuts if you pay a shop to do the work plus parts and misc for 25-50 HP. That’s a little high.

I’d rather see upgraded 2018 plus turbos with their the newly designed and way nicer compressor housings that are also already larger annnddd...... (anti-surge that’s legit and really nice....cough cough ) and perhaps a little magic sauce to the turbine wheel etc... now we’re looking at something that’s worth spending a few grand on. 50rwhp Max now ideally jumps to 150 rwhp and compare that to gen1 your up 250 rwhp.

Just thinking out loud, but I like the update option, just not with factory guts. Get more out of the whole spending the cheddar


PS: I’m agreeing with you, just not on oem for oem between years. Too costly for not much if doing the work yourself

Also- perhaps you know. Is there an updated connector on 17-18 on e wastegates that doesn’t plug right into the 18+ or am I mistaken?

We have put our modified 17 turbos on an 18 raptor without issue. I will check to see if there is some new connector maybe next week.

Thank you. I can tell you that modifying and changing a 2011-2016 to a 2018-2019 is not a walk-in the park. It requires detailed knowledge of fittings, etc....and not cheap. Although really cool to me

Is this a worthwhile endeavor with GT’s being available? Any advantage?

Although I have heard GT’s aren’t necessarily available.

I have gen 1 turbos with gen 2 guts in them.... Have the gt turbos become unavailable as of late?

I have a 18, just seems really strong compared to the 17 I drove, the 17 was equally equipped, wondering if the turbos are the reason.

Same octane fuel and everything? They seem to pick up 30hp or so to the wheel just by running 93 vs 87, even stock.

I'll let you know once I hit the Dyno. It's not a apples to apples since I now have the built motor in the truck, but I think we'll have some data worth looking at.

Matt may have better comparison numbers though.
