Hey everyone,  I got a 2017 MKZ 3.0t, AWD. I bought this car 3 months ago and i love it lol..its fun having a sleeper. Since, I already have a 800hp 350z, I wanted to try something different. I got the Steeda intake, 70mm tb, LMS thermostat, LMS throttle enhancer, GFB bov and1.5" lowering springs. All on my car now. I'm waiting for the charge pipes to come before we can install that with the upgraded FMIC. Only parts after that is to get the downpipes from Umtimate Performance and then we will fab up a cat back using borla mufflers, then the tune from Livernoise. My questions are, is there anyone upgrading the forged internals for this engine or anything? I know parts of this engine shares other platforms, I was wondering what would fit?  And if something can work, what could work with fuel management? Any information would be great. Anyway, thanks for your time.

Hi Ambitious_laZy.   Your question is being moved to the "General Engine, Powertrain and Transmission" sub-forum. The "Forum Help and Suggestions" sub-forum is for help and questions about the Lincoln MKZ Forum site itself.

Good luck.

Hm highly doubt anyone has gotten far enough to even consider upgrading the turbochargers for more power. Much less going to block internal upgrades. Transverse engine has less after market support going for it. So looking at full custom upgrade work if talking about turbo and engine internal upgrades. The Fusion Sports benefit more so from taking MKZ parts.

Better crack open the wallet if going serious in custom work.

Who's/which 70mm throttle body did you use? And how much material did you have to remove from the intake manifold to port match that throttle body?

Sanity check: isn't the intake manifold 65mm, and isn't it also plastic?

There are two choices: 65mm BBK and 70mm Ford Performance. Either one will bolt on perfectly and match the intake manifold inlet. The manifold is a plastic material, but it will resist heat soak better than aluminium beyond just being cheaper.

The larger throttle body compliments an Air intake and Intercooler upgrade in promising unrestricted intake manifold air delivery, and the IAT2 temps drop further over stock when in motion. My MKZ was resisting heat soak when under load much better over stock, whereas in stock form temps would just rise as more was demanded out of it.

It's a final touch mod, if you want to optimize a bit more after doing other upgrades.

Unfortunately I do not have my FORScan logs reflecting this anymore.
