I think it's a dumb idea. If you're gonna do it, at least put in a Ford powerplant. Maybe a 2.3T or something similar. Also remember the 68 is about as aerodynamic as a motorhome so you're gonna be fighting drag at higher speeds where your 100HP/5ftlb TOYOTA motor will be foot to the floor to keep it rolling.

I think you'd loose cred with the Mustang guys, and probably the import guys too. And, I'm pretty sure it's almost as bad as treason.

But, you know what they say, your car do what you will..

 

Dude...you must have a whole lotta "extra" time on your hands....LOL

 

What do you guys think? Has anyone heard of someone doing a swap like this? I've only ever heard of people putting larger engines in their Mustangs, never smaller.

Yes, I'm sure it can be made to work.

Yes, the Toy motor is a far better piece than the Ford 2.3, which I consider to be a horrendous, shaky piece of crap.

The 22RE is not going to get any better mileage than a well-set-up 200ci six will, but it will be more powerful.

If you consider the money (and possibly the monetary value of your time) involved in the swap and THEN redoing it again later with something else if that's your intent, vs just doing things once with a mild EFI 302 and 3.00 rear gears for ~20mpg, you're not going to save a dime.

 

I've thought of swapping the 302 out of my wagon for a I6 to get more fuel economy. I think it would be cool to have a smaller engine, just because it's different. The Toyota 4cyl engine, well it'd be cool for a few minutes but I don't think you're doing it to impress anyone. I have mixed parts on my cars, dodge transmission and seats and off brand front brakes in my 66 Mustang. Ford transmission, rear end and driveshaft in my Barracuda. I don't mess with engines though.
I'm thinking about a 3.0 BMW I6 in a 65/66 with a 6 speed. That would would be fun.

 

i think its a bad idea if you need more than 20 mpg your driving the wrong car

 

Another one for the category of "What can I do to my Mustang to turn into: Not a Mustang". And ruin the resale value of it too.
Doesn't work for me. I have two brothers in law and a couple of friends who are quite fond of their old 22RE Toyota trucks. Good mileage is NOT one of the points they brag about.
A couple of guys here have accomplished putting a 2.3 turbo engine in their cars. Not at all easy but pretty good results can be had. If one was put on Ebay, we'd likely see people looking at it and commenting about how interesting/unusual it is. (OK, and the haters, because they always are some) Now if a Mustang with a 22RE was on Ebay we'd see comments like WTF! And what the **** was he thinking? Odds are it would sell cheap and the buyer would have in mind "rescuing" the car by discarding the Toyota parts and putting in something more sensible.
I don't care about selling my car, but it's nice to have people offer money for it occasionally rather then just walking away shaking their heads muttering "WTF".That's my version of "resale value".
You don't want to be the "WTF" guy, do you?

 

Well, I did some more research (which I should have done in the first place, lol), and it looks like people with Toyota pickups with 22R-E's are getting gas mileage in the low 20 mpg range, which is about what people with Ford I6's in Mustangs are getting.

In terms of power and torque, the 200cid I6 si rated at 105 hp at 4400 RPM and 156 lb-ft at 2400 RPM, whereas the 22R-E is rated at 84 hp at 4600 RPM and 192 lb-ft at 3400 RPM.

So putting in a 22R-E would give me less power, more torque (although at higher RPM) and about the same gas mileage, compared to the engine already in the car. Thus the swap wouldn't really have any practical value. The only reason to do it would be because it's unusual, but I'm not sure it would be worth it for attention alone.

I'm not giving up on the idea of a nonstandard engine in the car, but it's clear that a 22R-E is not a good choice. I like the BMW I6 idea. It would still get bad mileage, but as bbpschools said, the Mustang is not about gas mileage. I need to remind myself that that's what my '88 Accord is for.

Apples and oranges, the 200 six rating is SAE gross, the 22R rating is SAE net. The Toy motor definitely makes more power than the old breathing-through-a-straw Ford six.

Want a suggestion? Up for some fabrication work and a certain amount of expense?

Get a 200 six from an '81 Fairmont/Zephyr with the bolt pattern and starter mount that'll accommodate (most of) a Fox bellhousing and T5 transmission. Build the six to about 9:1 compression. Then from an airflow standpoint treat it like a modestly-valved 2-liter four-cylinder because that's about all it's capable of.

The outlet from the late 200 manifold has a coffee-can-size catalyst hung off of it. With a little careful machine work one can make an adapter plate to hang a smallish (T25/GT25/GT28RS) turbocharger on there. It'd cost a bit, but you can throw some money at having the integral intake Extrude-Honed. Drill it for some injector bungs, find a throttle body off, say, a Chrysler 2.2L turbo four, stir it all together with about 8psi of boost and some flavor of tunable fuel injection.

 

It seems like you've decided not to do the swap. But it would drastically cut the value of your car. I know a lot of people say they don't care if something they do cuts the value, but you never know when you might decide to sell it. And last I checked, you're the only person I've ever heard of wanting a Toyota engine in a Mustang.

Just my 2 cents

Frankly, if he wanted to put a 2JZ-GTE in there I'd be all for it

But a GM LSA would be even better!

Buick 401 nailhead?

Just rubbing in the salt...

Frankly, I'm looking forward to seeing the RWD-packaged 3.5L twin-turbo 'Ecoboost' motors from the 2011 F150 start showing up in junkyards. Something like that cranked up a little with a T56 (or even just the 6-speed slushbox) in a '66 Falcon might be a lot of fun...

 

yes its not about the gas milage its about having people drool over your car and your friends beg to come over so they can work on it with you

 

Okay, but you asked.............
If you want a classic, buy an old Mustang and restore it, but if you want an econo box buy a Prius, a Honda or some other flavor of Toyota. These are at opposite ends of the spectrum. Reasonable project cars are now getting fairly scarce for those who want a Mustang as a Mustang. If it's mileage you're after you need to go with a small diesel that will give 50mpg. The air flow on a 60's Mustang is not efficient. I think you're going to waste a lot of time and money and be very unhappy with the poor result, but then again it's up to you what you do.

I'd put this a different way:

Rather than trying to turn an old Mustang into something it isn't, park it and run something else that fits your requirements better.

If it needs to be a Ford, there's still enough Mk1 and Mk2 Capris around to warrant paying attention to (and I've got a guy with access to lots of Capri parts) - they're quite nice to drive and will actually get out of their own way with the 2-liter SOHC motor.

Some of us have slightly more arcane tastes; I've got a Mk1 Cortina shell in the side yard and a collection of the rest of the sheetmetal in the shed. The plan is tentatively for a 1.8 Miata powertrain, but that's not set in stone yet. Maybe a 3.1/3.4 GM 60-degree V6 out of a Camaro.

Buick/Rover V8 swaps are not uncommon in the UK, the Ford 302 fits nicely with some attention to package length, I'd bet even a GM LS1-family motor would fit fine (engine compartment plenty wide, length is the constraint.) Big issue is tunnel space for a big-motor transmission and getting the sump to fit the crossmember and vice versa.

But how much power do you need in an 1800lb car?

 

I went with the 2.3 Turbo engine with an A4LD trany, for my daughters 66 Mustang. There are many 2.3 turbo motors out there with over 200,000 miles on them. My daughters car has 300+ rwhp and gets real close to 30 MPG. Just search 2.3 turbo 1966 mustang and you can find out everything about it. So far it is the only one you will find on the web that I know of or go to Pictures by angliagasser - Photobucket and start form there and work your way forward to see the whole build, or go to YouTube and enter GT140T for video's of it.
There are guys out there with these 2.3 turbo's with well over 500 rwhp and get 25 mpg. A HIPO 298 only had 275 hp at the crank. My daughters 66 mustang with a 2.3 turbo has over 375hp at the crank. Oh Ya, the car only weigh's 2500lbs.
The proof is in the pudding, as they say!

 

Check your local salvage yards for a Lada motor, now that would be an eye opener.

 

We're pretty much on the wrong side of the ocean for Lada engines.

 

I once replaced a bad 289 with a 200 I6 with a 3 speed manual behind it and was getting 20 MPG around town and 28 MPG on the highway. This was in a 67 convertible, using Sears Spectrum 10W-40 motor oil. Maybe the gas these days doesn't give the mileage in the older engines that leaded gas did. Keep the 200!!!

 

I've owned as many 80s Toyota trucks as I have Classic Mustangs, I wouldn't think of combining the two, there just aren't any advantages, you'd be better off saving the time and money and using it to pay for the gas on the Mustang, you'd go for years before you used up that $ you saved on not doing the conversion.

Besides, the gas mileage of the Toyota really is around 17.

 

Why not just a modern Ranger combo engine/tranny? Good gas mileage and cheap, plus still all Ford...Al to boot.

 

How about you fix the Toyota truck, and the Mustang.

Being happy is being satisfied with what you got.

 

If you want unusual, find a turbo charged Datsun 260Z engine. You'll get good MPGs and more power. Good luck

 

Angliagasser,

That SVO 2.3 Turbo is one cool swap. I hit this thread late, but after reading the 1st post I thought the SVO 2.3 Turbo would be a much better swap than some crappy Toyota engine.

 

hows about a 4 cylinder turbo diesel? it would definitely get you the gas mileage you're looking for, and some of that torque wouldn't be frowned upon either. bellowing black smoke out of a classic mustang onto say a civic or prius wouldn't get old, IMO.
