Good evening,

I drive mid-80s Toyota Tercels and am finally hoping to find a way to get a 1.6L TDI engine shoe-horned into one for a repower. Looking for 100 hp and 100 ft-lbs approximately.

My question: I believe I can find a “frozen” 81’ 1.6L block local, are the engine mounts, trans bolt pattern and general dimensions the same as the later TDI engines? TIA.

I will also be considering the slanted engine set up with the shallow oil pan. I see some on ebay, but would there be any available here? Again, thank you.

Look for an alh instead. You’re on your own for an adapter, but you can look up info in the Toyota truck forums since those guys frequently swap them in. My coworker did a 1.6 and said he wouldn’t waste his time with those, the alh is a way better starting point.

Thanks DCM1,

There is a real chance I won’t be able to make a diesel fit in this application. At this point I’m just looking for something to “mock” up. Would the 1.6 share mounts, bolt pattern, dimensions with the ALH? The ALH will be 1.9 and a little taller, correct?

Stock engine in the Tercel is 63 hp and less torque. Love the car, just want a little more low end torque and power. Too much and there are likely to be drivetrain issues.

I doubt if there is anyone on earth that can answer your questions. It's such an odd request. I think the only way to know if it will work is to do it yourself. If you do not have the skills and tools to make such parts you will need, I would find something that has Toyota on it. There has got to be at least one engine that would be a fairly easy bolt up. Heck, put a turbo on the stock engine. That would give you what you are looking for.

I’m currently running a 4a out of an 85’ Chevrolet Nova. The only easy swap on these cars, but not much for gains. Others have gone to the effort to install a 4age, but again, that’s more high rpm power, not low end torque (and likely a similar amount of work). Only easier, as it’s been done a few times.

Soooo, nobody on earth can tell me if the early 80s 1.6 has the same dimensions and bolt pattern as the newer 1.6 tdi? I didn’t realize it was that hard of a question?

I’m wanting to off-road and need power at low speeds. Turbo on a gas engine isn’t much bonus for low-end torque.

I think the bolt pattern is all the same on the diesels, at least that’s what I’ve heard. Saying a turbo won’t work isn’t really an accurate statement, since you can match the turbo to the desired rpm range. Talk to a turbo specialist shop and they can even setup up with a turbo that comes into boost at whatever rpm you specify.

I think part of the issue is that there are no 1.6L TDIs in North America as far as I know, at least no vehicles that came with them from the factory. Considering that 1.9L TDIs are a regularly swapped into MK1s either with the original 020 trans or the factory transmissions, I would say the bolt patterns are the same and dimensions are very similar, at least for the 1.9L TDIs.

OK, I get it. When someone says they are going to shoe horn a VW diesel engine in their Toyota I was thinking it was the engine, not the entire powertrain.

Now that I got my head out of my a$$, I can follow this thread without wondering 'Is everyone here just nuts?'

I do agree you can properly size a turbo to get good power where you want it. Most seem to think bigger is better and I honestly think that is just pain old foolish. There were days when turbo gas engines first came out that the power came on with a bang at the top end. I've driven a few of those cars in the late 70's/early 80's and they were terrible. Today's turbo engines are so much easier to drive.

Haha! On those old tercels, the engine sits longitudinally but it’s got a funky transaxle bolted to it, plus a transfer gear in the 4wd versions. Based on the initial post, it would appear that the intent is to adapt a diesel vw engine onto the transaxle.

Yeah exactly…a big laggy turbo would achieve the opposite effect as desired. Gotta make the turbo work with the rpm range and power band of the engine, not just grab the cheapest Cummins Holset off Craigslist and hope it works

When I turbo'd my 81 Rabbit pickup with a 1.8L, I spent hours looking at maps and did my best to predict what would happen when I installed a modified Mercedes 300DT turbocharger in it. When I got my build running [it's never completed] I had a smile on my face when I did the first full throttle run. Max boost at just over 2k and building boost at just over 1.6k. Full throttle at freeway speeds does not need a downshift to 4th.

Can’t help but think this is really dumb thread


Let me hold your hand for a moment

Your Tercel gets over 40mpg

Have you calculated how many trouble free miles you will need before you recoup costs?

For example.
The ecu on a Tdi

If you do the swap to gain 15mpg.
How many miles until the cost of an ecu tune/ injector pump will be justified.

You are going to find you’ll need 100,000+ miles of problem free operation
… guess what, by that time it’s time for repairs/maintenance.

And you are just assuming any used lump you get is good forever?

Not even taking into account the cost of adapter kit/flywheel
Custom mounts ect
And you’re trans is going to have wrong gearing.
Also not meant for torque.

Ok you’ll just do a 1.6d/td
But that only gets 40mpg
When you’re engine gets 40mpg
So why

Are you going mTDI or drive by wire.
Now you’re looking at a donor car to adapt a bunch of junk to your clunker.

When for 1/10th the work u could get kit to put it into a mk1 if you must have maximum mpg.
Or for1/100 the work just get a Tdi.

I just don’t like so much time wasted on a poorly thought out plan
