How to resurrect an old engine design no longer made?

I suppose that may be accurate for new versions. I daily drive a 20 year old turbocharged, intercooled, fuel injected 5 banger that puts out 300 horsepower. It gets regular 7500 mile synthetic oil changes. And that's about all the maintenance it has needed for the past 20 years with me beating on it.

What is that, a Volvo?
 
I understand, and I'm here for the debate, not to be inflammatory.

Let's look at it this way....Toyota is coming to the game late for general mass produced complex turbo engines....but why not look at what is out there already and learn from the mistakes. Ford has had twin turbo V6 engines for nearly 15 years....and yes....at first they were terrible....but look now....while many will say they are terrible....the Ford Ecoboost will achieve great distances with decent....not even immaculate maintenance.

Honda has been using single turbo setup in their big sellers for nearly 10 years now and they are good and pretty much problem free.

Toyota dropped the ball on their twin turbo 4. They did great on the single turbo V6.

In the end the world requires less emissions not matter what....and a vehicle that can barely pull itself at highway speeds is not safe any longer. Think about your own driving experience back in 1999 and 2000 and compare it to now. The amount of speed we travel at and number of cars on the road is staggering compared to back then. I mean really....think back.....it's way different.

I think there are some really interesting engines that combine the ability to have good power and torque without winding it out to the moon which will help in the long term with reliability.....which brings us full circle back to the OP statement.

I am not saying bring back the 4.0 from AMC or Jeep....but space aside.....why didn't Ford say I6 single turbo would be a good platform back in 2011 or 2012....whenever the Ecoboost came out.....and don't say development........Mazda bought back an I6 without ever using one in their lineup ever. They made a very good engine.

The switch to smaller turbo engines has a lot to do with governmental regulations around fuel economy, emissions, etc.

Of course I'm positive that we would agree the the government forces many things on was that have lasting effects on our lives . Good move on ditching the F-150 , great truck until the cam phasers , timing chain/guides tensioner start to jump through their ass . my son in law was looking at a $7500.00 repair so they traded theirs off. The only thing that tows worse than our Taco is our TJ's ! However if you keep under the max tow weight and drive slow you can get by.

Yep, that was my next thought! Only the Europeans seem to do 5-bangers.

Indeed! I towed with my Taco a number of times and it got by. I just stayed in the slow lane on the highway. Interestingly enough, TRD made some old Eaton style superchargers for the 3.4 you can occasionally find on eBay. Not that I would bother, but I thought that was interesting! I'm just happier keeping things N/A to be honest. It's just so much simpler.

The cam phasers make noise on start-up for 10 seconds or so. That's the next thing I'm anticipating and at this point I just want to be done with it. The fact that Ford ever released such a half-baked engine is absurd. Man does it have power though, that's for sure.

Should have just kept my 04 Tacoma at this point, honestly! If it means going a little slower and sacrificing some power, so be it.

I'm really looking forward to daily'ing the K10 during the nice months. I've started on the transmission swap too.
 
I never would've guessed it to cost that much! I watch too many motor trend shows where guys rebuild engines for a few thousand I guess!

Take a look for yourself. https://blueprintengines.com/ They offer core rebuilds and new SBC builds.

New bare blocks run in the few thousand range and still need final machining.

"Why hasn't someone started producing a copy of the AMC 4.0?"

99.9% of the people won't buy it for what it would cost to do it right. Most would buy an entire vehicle with lower mileage (compared to theirs) engine, swap and be done with it .. or just go with reman and roll the dice.

Mazda I6 turbo is a great engine and other manufacturers should take a look at it. Very efficient, good power and has a good track record thus far.

Stellantis I6 Turbo Hurricane engine appears to be good thus far as well.

Why use archaiac design when newer more efficient I6 engines exist....hell I would take a Ford 300 I6 over a 4.0. Best I can see for 25+ years I have had one....they barely can pull themselves around. Sure they are great at not breaking....but what's the point if you can't motivate your own self?????

Are you going to do all the small nitty girtty work (that all adds up both timewise and costwise) to swap any those engines in, while also making sure you have a functional working suspension without doing shit compromises just to fit the engine in? If not you, are you prepared to pay what it would take to someone that is capable of doing it right?

<snip> I'm in the process of getting rid of my F150. It's an awesome truck to drive but I know it's going to turn into a maintenance nightmare in the long run and I am at the stage in my life where I want to buy vehicles that can last me for decades (ones that I can work on myself also).

What are you replacing it with, if any, for a daily driver? :) I think the challenge with older vehicles is that even if you are OK initially, in the longer run you have to accept the compromises in terms of size/power/comforts/modern_amenities and it's a very conscious choice that you have to make for a daily driver (not talking about special cars like your K10 here).

compromises in terms of size/power/comforts/modern_amenities
Size: Newer vehicles are too fucking big.
Power: 100 HP in a passenger car, 150-200 in a light truck is plenty.
Comfort: Good supportive seats, A/C and cruise control - all of which can be retrofitted if need be.
"Modern" amenities: Oh HELL no!

My daily in the spring / summer will be my '73 K10. During the fall and winter I'll be driving the 2005 Toyota RAV4.

I totally agree with too big ! .gov put us on that path , larger footprint = less gas mileage and emissions to meet. Everything else should be personal choice .

I'll never get over this. I look at older Ford Rangers and Tacomas and think to myself, "what a great size for a truck". I see these things now and they're absolute beasts. Not just trucks either, all cars! At this point we might as well just bring back the huge Cadillacs of the 50s that looked like boats on land!

You live in Wyoming , can you at least put some cowboy mudflaps on the RAV4 ? Extra points for west coast mirrors , and in for the win if you have twin whip antennas mounted to them ! :)
