I-VTEC swap

Hey there I have an 88 manual Bronco II xlt with manual locking hubs, 4x4 . My engine is at 190xxx n still going strong so I figure now is the perfect time to start planning itís inevitable engine failure . Iím torn between a tdi diesel swap for the fuel mileage, except to get decent power(90hp stock) out of them you have to mod them a lot which I feel will lose all mpg advantage . So now Iím looking into a I-VTEC. These engines turn off half the engine at cruising speeds n low power times to conserve fuel but get 220(hp n torque) on stock engines. Honda pilots wieghing 4500lb get 19/28 mpg - although more aerodynamic they are a bit longer than the bronco n wider I believe. Theyíre very Similar to the standard v6 VTECís just more fuel efficient than fast - but with 80 more hp than my stock bronco I think Iíll be ok :p . So really Iím wondering if anyoneís swapped a Bronco II / ranger with a VTEC and if thereís any info on that around . I tried looking it up but it doesnít seem like a popular swap- I-VTEC j35 is the specific engine Iím looking at but any info on a VTEC swap would be helpful

Some additional info the I VTEC weighs 360lb with fluids I believe and isnít to different from the normal VTEC in means of dimensions, still trying to figure out exact measurements so I can figure out new mounting points . So Iím not sure with the added power if upgrading suspension and steering components is necessary but if so I donít mind doing it. Just trying to figure out what I should start planning on upgrading and what I should hold off on till I drop a new engine in. Example-I wanna redo exhaust but may wait to plan my exhaust around a new engine , or upgrading suspension steering now and get it out of way. Posted on bronco forum but no one chiming in, so ima try here

Welcome to the forum

First thing you need to do is to see if any non-Ranger engine can be used in Rear Wheel Drive(RWD) vehicle easily, i.e. is there a transmission, manual or automatic that can be used with that engine in RWD setup
Custom Adapter plates are expensive
FWD is much more common on vehicles now-a-days
And even if it can be adapted, like the 2.3l DOHC duratec engine was, you do have service issue like the rear cooling hoses on this engine, you have to take transmission out to service them, lol, not the best planning there

Next is engine dimensions
The Windsor 302 V8 is a tight squeeze, it is 19" wide, 28" long and 21" high
The width is the biggest issue because its set by the heater box on passenger side and the steering arm/rod on drivers side
Heater box can be modified to some extent, steering arm is a little tougher but can be done with universal knuckles
You can do a body lift to get more height in engine bay

The Mazda L engine, info here: https://en.wikipedia.org/wiki/Mazda_L_engine
This was what Ford used in 2001 and up Rangers as the 2,3l Duratec and the 2004 and up version did manage 143HP, with OK MPG in 3,200lbs Ranger, 24/29
Bronco II is 3,400LBS
There were iVCT versions available in Mazda vehicles and Ford did start Ecoboost versions based on this engine but it is not the same engine
Since this engine was used in RWD Rangers then transmissions will be available, in 2WD only, M5OD-R1 manual trans from a 2.3l duratec could be converted to 4WD with some disassembly, automatic would be much harder to convert


No, I haven't read about swapping in a Honda engine to Ranger or B2
Diesel VW engines have been done, and with good results

Looking at a K20 Type R Honda motor to swap?

Me likie your direction, but...

I wonder if a 2.0L Focus ST or Fiesta ST turbo motor (250+ HP) will actually bolt up to a Ranger trans.

Even better, the RS lines...350 HP 2.3L Ecoboost motor

Were the blocks different (more to the point...trans bolt patterns) from the Duratec and Ecoboost lines?

Imagine dropping one of those into your Ranger's engine bay.

The 2.3l Duratec and 2.3 Ecoboost should have the same trans bolt pattern

Ford bellhousing pattern list here:https://en.wikipedia.org/wiki/List_o...using_patterns

Duratec I4 pattern

2.3l Duratec never came in 4WD models so that part would need to be dealt with

I'm guessing that adapting the 2wd trans to 4wd is not easy. Do the tail housings swap over?

Yeah, theyíll swap over, but the output shaft also needs to be changed. 4wd has a short shaft and that tail piece bolts to the transfer case. The 2wd shaft is longer, and so is the tail housing.

Partial disassembly is required to convert 2WD M5OD-R1(manual trans) to 4WD, or visa versa

Automatics require full rebuild to replace main shaft

I looked at the Duarteís/ecobost , they seem like a good option but more expensive due to the cars theyíre found in/year. While Ik the ivtec will be way more work - we have odyssey with them in there for 700 around me n pilots for 2g. Iíd save over 1500$ each year with 10mpg so whatever my options they can be justified:p

ill look into that stuff today tho, from the dimensions Iíve found so far I believe itís slighty smaller width n length but taller. My main concern is what you pointed out , itís mounted transversely but i figure with the diesel Iíd have get mounts welded anyways . And worst of all they donít come in manual(absolute must for me) and I need a transfer case . So I was gonna look into trying to adabt a m5/fm146. Although if Iím going that far into a project I might look for a 6 speed

So I think the t56 out of a mustang is what I can find suggestions on, luckily the j35 ivtec spins the correct way to set it up as rwd, only reason Iíd stick with FM146 is I love its 1st gear and the removable bell housing seems like it could make things a tad bit complicated. All this information is difficult to find sadly since no one with a minivan cares to mod there engine and anyone looking for a Vtec swap is looking for raw power. Btw thank you for everyoneís input n not bashing on my over complicated idea :)

You DO occasionally find those "pioneers" that got fed up with being a dad in a minivan and wanted to spice their family wagon up. Imagine a 9-sec Grand Caravan

An interesting project you present, though. The biggest obstacle I can see is the bellhousing (or at least, an adapter plate) as it likely does not exist. I'm no forger nor fabricator, but to get a Honda motor to mate to a Ford trans will take a lot of work. Flywheel/flexplate customization may be challenging, too.

I don't know if this will work, it's just a thought...Spitballing because you would likely be the guinea pig and the only one with this setup and I have seen a K24 twin-turbo Honda inside a Toyota Tacoma for drag racing...

Find a CNC milling dude with good equipment. Get good scans/measurements of both the trans from the Ford and the engine from the Honda, line up the centerlines of the output from the engine and input to the trans and mill an adapter plate.

And now, the bashing

Thoughts on that will be the trial and error adjustments, while in the meantime, your wallet gets drained while they fine-tune any vibrations.

That cost savings you thought you might have been getting with choosing the Honda over a Duratec/Ecoboost may flip the other way in no-time.

Lastly, you live in CA. We are obligated to adhere to certain guidelines and laws when swapping equipment on emissions-controlled vehicles. This may prevent you from this project unless it's "off-road use only". Check the CA statutes to be clear.

Total disclosure...I used to swap Buick V6s and Chevy V8s into Toyota trucks in the 90s, so my info may be a bit old.

It's not to discourage you, but to inform you of certain variables that can and will affect your project.

I hope it does work out for you. Let us know what happens!

I wondered about the emissions, Iím in Northern California (humbolt county) n they only require you to smog once here when registered in ur name but if I ever move I might be screwed - however while researching I came across some info thatís bothers me more than tranny - apparently the switch from v6 to i3 causes strain on the front motor mount (transverse mounting) which I feel will further complicate once switching to longitudinal mounting. And most are saying itís only a 1-2 mph gain from Vmc to non-vmc. Iím still looking into the normal Vtec now but more open to other possibilities now. My goal is to squeeze 10 mpg out of this engine while producing pretty good power still. Ima reader has the Duarteís/EcoBoost more but would like to stick with a v6 over i4 ( donít like the sound) ik Iím picky with my **** . But these broncos are my dream car(size,visibility,comfort, overall cosmetic design) and I got it for 600$ I figure I could drop 15 grand into it over time and make myself a custom brand new car and still save $ vs buying one off the lot and still not being satisfied

Calif. is strict but as long as the engine is 1988 or newer(in a 1988 B2) then it should be OK
But you will need documentation for the YEAR of the engine you use, and then it must meet that years emission requirements, you must be able to PROVE the year of the engine, so what ever engine you get, get something from seller that has the year, like the VIN for the vehicle it came from, wrecked/salvaged vehicle VINs are recorded, so it can be looked up by the state as proof of year

And because your VIN will no longer match, engine size is in the VIN, then you must also get an inspection first, they check the whole vehicle for road worthiness, before smog test
You will get a savaged title or custom title after inspection, this is because VIN no longer matches for engine size/type

I am worried about emissions testing but the smog shops in humbolt are so of the coolest shops ik - they donít charge if you donít past and on one of my engine swaps the computer throw like 50 codes after 100 miles of driving - guy spent an hour figuring out which ones needed to be fixed so I could reset battery -> drive short distance and smog before the rest popped up - on top of that he refused my money until it passed and only charged me 40$ , I tipped him another 40$ since i seem to fail a lot :p but Iíve got it narrowed down to this

J35a6 I-Vtec -> custom bellhousing-> T56 tranny(2.97-.62 ratio) -> short shaft -> divorced transfer case -> stock rear axel with 4.11 gear

The cool thing about this project is I can get the engine from a 04-06 odyssey (600-700) for donor car- and the tranny from local pnp for 150$ - I figure 2g for parts to rebuild engine n tranny , 1g for custom welds , 500$ for custom bellhousing, 500$ for driveshafts im debating just getting another Bronco II (like 400$) with a blown head gasket to do this project on since Iíd like to still drive my bronco during the months this project takes - and please add to my expenses , if you see something I forgot but all and all if it goes smoothly Iím expecting 5k to get engine n tranny in there and have it start (not expecting it to be smooth) then another 5k in reserve for random bs.

Now what I need help figuring out , do they make transfer cases with varying high gears ? Iím not making this car to win races but I would like to put all the growers in there place , they all buy retardly expensive trucks And ride everyoneís asses cause they own a 50,000$ truck n think theyíre the **** ( donít get me started on my personal vendetta against them). But essentially what Iím getting at is even with the highest geared t56 trans , Iím really only gonna use the Vtec(switches at 4100) part of the engine in first(30-40) and second (40-60)but the gearing is perfect with what Iím planning 2000 rpm at 65mph in 5th and 2000 at 80 in 6th - but Iím wondering if I can get a transfer case that when putting it in 4h it raises the gear ration so I can get higher rpms at lower speeds than 2h for a quick pull out .

is there a transfer out there that does this? I know atlas 4speed has 3 low gears but I usually only need 1low to crawl around farm with a trailer and some light crawling around the river.

Once again thank you for your input ik this is a Honda engine but the Honda forums suck compared to the openness of ford owners . You guys are the best

No, there is only one gear set in a transfer case, 4low
2wd and 4high is just a straight thru drive shaft with a coupler that can be engaged to power front drive line

Gear Vendors makes a manual gear splitter, makes a 5 speed into a 10 speed, lol
Its the same as a two speed rear axle, but smaller
