After much deliberation on whether to upgrade my PRV or go with something else, I've decided on a 3.5L Ecoboost swap. I've owned a couple of trucks with 3.5's and I'm a big fan of that motor. I think it would be a great fit for a Delorean because of its size, weight, and power. Ford makes a 3.5 crate motor with a control pack for swapping to a different vehicle. It even comes with a drive-by-wire accelerator pedal. The crate models make 360 hp and 400 ft/lbs of torque. I'm planning on using an upgraded UN1 gearbox. There are a few different companies that offer single piece shafts and limited slip for our gearboxes, sounds like they'll handle 500 hp if they're built properly. My car is currently an automatic, so I'll have to do the proper frame mods for the swap. The biggest downside to this is going to be the cost. New Ecoboost motors are damn expensive. I wouldn't mind using a low mile junk yard motor, but using Ford's control pack on a non-crate engine causes a no start condition. Thanks a lot, Ford. I've heard there are aftermarket control packs, but they're much more expensive. Still have to research that more. Another thing I'll have to tackle is figuring out a charge cooling system for the car. I know how all this stuff works, but I'm not a turbo whiz by any means. One nice thing about these motors is that they come as a fully integrated package with the turbos mounted on the engine, which will save a lot of time figuring out hoses and exhaust.
This project is something I'm going to take my time with and make sure I fully research everything. I'll probably start by getting the gearbox and bellhousing built, then try to track down an engine. I'm hoping by the time I reach that point Ford's crate motor is upgraded to the latest Ecoboost series, which is built a little better, or maybe I can find a different solution with an aftermarket control pack.
I'm looking at about a 2 year timeline to get this done. I'm a very busy guy so my spare time to do things like this are limited. Any advice is much appreciated, hopefully I can get all the bases covered research-wise before I start on this.
