I don't disagree that you could build yourself a powerful N/A modular stroker and/or a blown modular set up that would rival and in the case of the blown modular, surpass the power output of the new Coyote…but let’s look at what’s really involved here?
I do find it a little comical that you suggest the time and effort involved in installing a wiring harness to transplant the Coyote isn’t worth the trouble, yet sourcing and building your own modular short block from scratch with aftermarket parts, along with all of the supporting parts and hardware (exhaust, intake, tuning, bolts, nuts, etc) required in order to complete the build and come anywhere close to the power and drivability levels of the new Coyote barely get’s a reaction from you.
The fact that installing said wire harness and making it work with your factory gauges makes this install challenging enough. Add to that the speculation that these engines don't always run right when swapped with the FRPP control pack and you might start to question whether or not spending $7500 is worth it. That 7500 also doesn't include headers, intake tubing, and other misc parts necessary to make this swap work.
And let’s be frank here. You’re not going to come anywhere close to 412hp/390tq with a N/A 4.6L 2V/4V modular and still end up anywhere close to meeting the Coyote’s smooth idle, flawless street manners, near 30mpg fuel economy or sparse emissions output….all of which is accomplished on 87-octane pump gas. As the matter of fact…you aren’t coming anywhere close to those levels without the use of a power adder…and we all know how expensive the game gets after that.
Funny that Mr. PD Nutswinger himself is saying this. A complete KB kit can be purchased for under $6,000 and will provide 400 RWHP and 400 RWTQ. Structurally the KB blowers are solid units meaning if you wreck your engine the SC is fine. You can install a junk yard replacement engine for under $1500 AND if you ever have a desire to upgrade to a forged short block you have room to grow with that PD blower. That's 2 engines AND a supercharger for the same price as the coyote w/ harness.
Don't forget that the coyote's 412 hp is not rated at the wheels, and certainly doesn't have the broad torque curve a KB supercharged 4.6 has.
Regarding driveability, you're always going on and on and on about how PD blower cars have such great street manners. So Brian, are you saying a N/A Coyote offers better drivability than a PD 4.6?
Where have you seen a real SN-95 car with a coyote engine making 30 MPG's... also, are you certain the coyote makes 412 hp while running 87 octane gas? I doubt it...
Furthermore, with the Coyote package you’re getting a turnkey, plug and play crate engine, complete with 12-month, 12,000-mile warranty. Remind me again what the warranty is like when you build your own modular in your garage at home?
Where exactly is the cost savings?
Considering that you'd have to remove that engine and send it back to Ford with a warranty that is only 12 months... BFD... I doubt there are many properly installed KB 4.6's that have ruined motors within 12 months.
For $1500 less than it would cost to buy the Coyote engine and harness, I could buy a KB kit, install it on 2 weekend afternoons, and make more power across the RPM band than the Coyote makes.
