Engine swap
Engine swap
hi everyone I’m the newoldranger. I would like to ask if I could swap a 4.0 8th dig E 06 ranger the engine into a 2000 4.0 ranger 8 dig X? What would be some things that would prevent the swap?
Thanks
Thanks
Welcome to the forum
1990-2000 Rangers have the 160hp 4.0l OHV engines, VIN X
2001 and up Rangers got the 205hp 4.0l SOHC engines, VIN E
The motor mounts and transmission bolt patterns are the same, 4.0l SOHC has one extra bolt hole but not a deal breaker.
Computer and engine wiring harness are not the same, and there are some other issues
2004 and up Rangers had digital processors in the instrument cluster which are "married" to the computer, so computer won't work without that dash, and then there is a Smart Junction box(body computer) which was also part of the 2004 and up changes made.
So it all needs to be brought over to get 2004 and up computer working
To avoid all this you would need to use a 2001 to 2003 4.0l SOHC computer and wiring harness, you still have PATS(passive anti-theft system) to deal with but you can often get working PATS key or keys with used 2001-2003 computer and wiring harness, if not then Mobile Locksmith can make new PATS keys or add your working 2000 PATS key numbers to the newer computer
Is it a "good swap".................in my opinion no it isn't
You can go out an buy a Factory 4.0l SOHC Ranger or Mazda B4000 if you want the extra HP
If you have a bad 4.0l OHV in your 2000 then fix it or swap in a 4.0l OHV, sell it and get a newer factory 4.0l SOHC Ranger
The 4.0l SOHC swap is only slightly less work than the 5.0l V8 swap, and you can't buy a factory V8 Ranger, so it has some value after the swap, 4.0l SOHC doesn't, its resale value is less than factory 4.0l OHV

Listen to RonD. He's a great resource to tap when you need some solid info.
If you are dead-set on the swap...
Going on a small tangent here, but depending on where you live, a V8 swap might be a difficult task. I live in California, and the laws here say you can only swap same-year or later engines into your vehicle.
You ARE in luck as 2001 was the last year Explorers were available the 5.0 Windsor V8. I have researched that this is a near bolt-in swap.
Of course, wiring and ECUs will be different.
Google it...Google it...Google it. Many of these swaps have been done, and a lot have even documented it on video.
According to Wiki, HP between the 4.0 SOHC and 5.0 V8 are identical, but that sweet torque, baby. You'll have a workhorse that can pull down small buildings and performance parts for this engine are plentiful where parts for the 4.0L are VERY few at best.
Rebuilding the 5.0 is sooooo much easier and cheaper, as well. Plan B would be to find a donor Explorer intact (or junkyard special with ECU and harnesses) with a blown head gasket or whatever rebuildable problem, rebuild yourself or use as a core for reman long block and make it a nice project.
If I had an older Ranger, I would do it in heartbeat. <3
If you are already set on swapping yours with the 4.0L SOHC, then you should look into a 2005 and later engine...timing chain tensioner issues with earlier years.
Or...
Use your engine as a core for a reman. Boring
Hope this helps.

On the California emissions note, I'm not sure if its county or not, but I'm 90% sure the donor engine also needs to be from the same vehicle class. i.e. Light truck to light truck, so on and so forth. So, I couldn't even take a 2004 or newer F-150 engine and fab it into my truck (not that I'd want to..) or pull a sweet diesel engine from a transit van and swap that in (which would be phukin sweet)
It's quite a possibility that these rules have changed from then to now to state what you've said. My suggestion is to make doubly sure.
Sidetracked...Could you shoehorn a 7.3 diesel into a Ranger engine bay? Whoa
