outrider02 Posted November 30, 2020 Report Share Posted November 30, 2020 Good morning community! My neighbors son has a 2009 Ford Edge, water pump went out, he overheated it, and now has low compression on the rear bank of cylinders. I'd guess some bearing damage from using antifreeze as a lubricant as well... I'm trying to help him get his car back on the road as cheaply as possible. We've found a 3.5 from an explorer locally that was ecoboost swapped, that we can pick up for a really good price, only problem being it's a 2015. I had completely abandoned the idea of using that engine since it has the dual variable cam timing, and it looked like that wouldn't be compatible. Maybe we could swap the heads, but then he'd still have to get his old heads surfaced, new head bolts, timing chains have to come off, etc, just didn't look to be worth the hassle (assuming it's even possible). Then this morning I was looking for the part numbers for the lifting eye and power steering line tools, and stumbled on a post where it sounded like someone did just that. So my question is, can the dual variable cam timing engine be swapped into an earlier model year? Thank you! Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 30, 2020 Report Share Posted November 30, 2020 it can if you upgrade the sensors, wiring harness and the PCM. Better to find a pre-2013 donor vehicle from Flex/Taurus/Explorer. OR get a 3.7 from a pre 2013 MKS, or 2007-2010 CX9. Also dropin propositions.

outrider02 Posted November 30, 2020 Author Report Share Posted November 30, 2020 We could swap the sensors from the existing engine, but I think I'd like to avoid swapping the harness or PCM. Even if I had one available cheap, I'm assuming there's more to it then just plugging it all in. I'll expand my searches to include the 3.7 though. Would one run on the 3.5's PCM without any issues? I did a quick search while writing this reply, and my 2 minutes of googling says yes, we just need to use the 3.5 crossover pipe, and the rest is plug and pray.

WWWPerfA_ZN0W Posted November 30, 2020 Report Share Posted November 30, 2020 As long as the engine is using a VCT and not a Ti-VCT management system, it should drop right in. Yes the crossover pipe could be a variable, good point. Not sure you can swap the sensors between VCT and Ti-VCT engines. The flywheel can also be different.
