Engine Swap options

lol

1, 2 and 3TC's came in the early 70's Corolla right. I was told that they use the same engine/trani mounting as a 22R.
Don't think it's gonna go in easy.

[toastyjosh]

its a long shot but this would be awsome

The only way I see that working is you will have to machine, or even weld and machine the trans bell housing so you can get bolt up to the block, and you would have to make sepcial engine mounts (I do not even see where the side engine mounts can fit).

I personally would rather stick to the engine family that at least allows the same trans and engine mounts to be used, even if it takes others mods. Those are easy compared to making the bell housing fit properly.

Good luck with that.

[toastyjosh]

yea It is really just a pipe dream. I just want a 4wd wagon that gets 50 or 60 mpg is that to much to ask? I am starting to realize that it my not happen. oh well

[Petros]

Good luck with that.

I think 40 to 42 mpg is likely possible with a more modern EFI gasoline engine, maybe more with a few tweaks to improve efficiency (44-45 mpg perhaps?). I have picked up a rwd 4age engine, but I am undecided if I am going to use it, or alter a 4afe (or even a 7afe) to fit in my Tercel. Perhaps I will get one of each and play around with them until I am satified which one is better. Any of these engines have much easier problems to overcome to make it work in the Tercel compared to what a Diesel conversion would require.

I have owned and driven several diesel powered vehicles for many miles (an old Mecedies,a chevy van, and a utility tractor for my property), and I just as soon never have another diesel powered vehicle again. Gas cost less, the engines are easier to service, and from my persective, are less troublesome. And Diesels really leave a bad smell where ever they go. No thanks.

[toastyjosh]

well 40 mpg and EFI would be a winner for me. As far as cost and being able to pull off the swap the 4afe or 7afe is most likely my best bet.Well thanks I will start looking more in that direction.

Petros, forgive me, but-
Get out of the 1980's.

Stop stereotyping.

Just because you probably drove a 5-cyl NA (or MAYBE a turbo) Mercedes, a dirt-basic engine known to not be the paramount of power and efficiency (but known to last over a million miles)
Or a Chevy van with a 6.2L NA clunkertron GM engine, maybe if you were lucky a clunkertron 6.5L Turbo IDI. Again, dirt simple technology.

Both of the above are Indirect Injection diesels. Inefficient and basic. If running wrong (as most are) then stinky.

I challenge you to go stand behind a new TDI. What do you smell? Maybe some hot air with a hint of combustion odor? How about a new 6.4L Powerstroke? Emissions lower than a 5 year old Honda Civic.

Modern diesels are far and away from their 80's ancestors.


"Gas is cheaper" is one of the most hilarious and idiotic statements around. Most diesels will get double (or dang near it) the fuel economy of an equivalent gas engine. Our Passat? 50mpg. A gasser Passat, even with the 2.0? Maybe 30. Our old 350 Suburban we had? Unloaded, maybe 15mpg. Loaded, about 8. Our 454? Unloaded (and probably with a tailwind going downhill) about 12mpg. Loaded? Typically 4mpg. Our Excursion diesel? Unloaded, about 17mpg. Loaded up (making the same run as we did with our earlier burbs and going about twice as fast up the hills) about 14-15mpg.


It does not take a genious to see that a 90 cent difference on $1.54 gasoline (and thats regular, which most modern cars have to start retarding with anything less than midgrade) is not enough to offset the gains.

Not to mention, if well cared for, most diesels will go for 500,000 miles. Most of the time rebuild-free. Turbo will go, if you have an injection pump it'll need rebuilding, and you'll need new injector nozzles about every 100k. But whoopdie-freakity-doo-da-day.


I understand putting a modern diesel in a Terc is not cost effective (2ADFHV comes to mind) but even so, an early 90's diesel set up correctly and tuned right will run essentially smoke-free, the smell will be minimized (especially if you keep a cat, and the right kind of cat) and you'll have a lot better torque and economy than an equivalent gas engine.


Not to mention.... 40+ is possible with a 3AC. I've done it before on my highway trips.


I will not pretend to dislike the idea of a better gasser in the Terc. Lord known it needs it. But to write diesels off because "they leave a bad smell wherever they go" is foolish, at best.

And BTW, the F-250's, 350's, Chevys, Dodges, etc trucks you see running around that belt smoke when they accelerate quickly... If they were built after about 98 (later for the Chevy's as in 98 they were still running the 6.5L IDI) then it did not come that way. That is the result of chiptuning and injecting too much fuel and not having enough boost.
Remember, the quickest and the fastest diesel trucks in the world right now spit zero black smoke. ZERO. They have their air-fuel balanced out properly.
So don't think you can't get a diesel and get speed and extra power without smoking everyone to death.

[Petros]

Petros, forgive me, but- Get out of the 1980's.

That is the only kind of Diesels I can afford. And I know the newer ones are better and do not smoke, they still smell funny. The cost of the newer engines and the effort to adapt them to fit the Tercel, is hardly a worth wile effort in my opinion. A waste of a good diesel. I like gasoline engines for performance, and it is more difficult to tweak a Diesel engine for more performance. I know it is done, but it is quite costly compared to a gas engine. And there are way more 4AGE/AFE/7AFE engines and spare parts out there than any suitable diesel.

It is difficult to compare "equivalent" gas and diesel engines, they behave very differently. If you get the same HP engines the diesels are still slow to accelerate, have way more torque, much heavier and would not be as economical. If you get the same torque value gas and diesel, it will be even slower, still heavier than the gas engine, but get great economy. You should also match gear ratios to take advantage of the the very different torque curves, also not practical or worthwhile (or cost effective).

So I am sticking to the easier swaps of engines in the same family that use a similar block design to ease the swap problems.

I have a '85 F250 with the International 6.9L IDI diesel. I run 20% Biodiesel minimum and Redline fuel catalyst. Very clean running, no smoke when floored as long as the RPMs are up a bit before you floor it. Regularly will get 18-20mpg if driven at lower speeds. Will get 15mpg at 65-70mph. This is a big 6k pound truck 4wd, extra cab, automatic trans & 8 foot bed. I'd be lucky to get 10mpg highway with a gas engine in it.

I personally love diesel engines. I like the smell, to me that smell means better efficiency. Better everything.

But putting a diesel in a tercel? I dont see that happening.

[Typrus]

I want to see you pit a 400HP car that weighs 3000lbs to a 400HP pickup that weights 7000lbs. The pickup will win. It will spank. When the 400HP car has maybe 400ft/lb and the pickup has 1000+ ft/lb, there will be no contest.

Put $2000, well placed, into both a gasser and a diesel. The diesel will always gain far far more.


Again, I reiterate. To put a modern diesel in a Terc would not be cost effective. Cool, yes, cost effective, no.

I am not trying to tell anyone they have to do diesel, but the negative stereotypes annoy me.

You have convinced me to put a diesel in my tercel. You did it typrus, gosh.

[Typrus]

lol...
I are so convincing. lol j/k.


Gotta remember, for quite some time I talked about trying the 4AGE conversion, but never got the money to try. So I am for it. I don't offroad much. I like to go fast on the paved roads. 4AGE is SWEET for that. A diesel is also, but a custom tranny, crossmember (to lower engine for RWD conversion as thats likely the only option) and other stuff makes it a bit difficult. Not to mention you lose the sweet Tercel 4wd 4wd.

[Neu]

Who takes their 4wd tercel's off road? They should only be used on road, as they're too cool to go off road and get damaged.
