WTB LD or SD

Buy it, sell it, negotiate, haggle, drag it out from under the workbench or behind the garage and make it someone else's problem!

WTB LD or SD

#1

Post by jag7720 »

I am looking for a Diesel engine to put into a Datsun 510. I'd love to have a turbo but that is not necessary.

I am not new to diesel but AM new to Dissan Diesel.

This engine looks like it would fit and the tranny looks to be the same as the Gas engines.

I am in the Kansas City area.

Jason, the SD engines will fit into the 510, but will not bolt up to the gasser version of the FS5W71 transmission. The only transmissions that will fit to the SD are the front-half of the diesel FS5W71 trans (rear half can be gasser or diesel, interchangeably), the Chrysler TF727 as used in '76-80 IH Scouts etc., and the manual trans from the same IH applications.

There are more modern diesel engine designs out there than the SD, if you're planning on a conversion.

The LD20(T) engines being imported now (they were never sold her) should bolt up to your 510's trans without modification, though I haven't actually done it. There is an LD-into-a-240Z thread here where someone mentioned a difference in the clutch fork.

Somewhere here or, I read elsewhere this same query about putting as SD 4cyl into a Datsun 510. At any rate, and SD is quite a bit heavier (est 475 lbs) compared to the orginal 1600cc gas engine (est 260 lbs). Also the RPM limit is lower and this is another problem considering the final pinion/ring ratio.

Pics of an LD20 are in this post. Remove that cast-iron bellhousing, and it looks a lot like an L16/18/20.

the old LD20 is a straight bolt in.use the 510 engine sump and engine mounts.for a daily driver it will not need much thought to set up.the LD20II will need a little thought but is a better deal.it will drive like a standard 1600 with lots more grunt.CD20/CD20T may need a good workshop if you want a city driver on bio fuel you may look at a CD17 sold in the usa.a turbo CD17was made but is rare.

510 will use a standard auto trans or a smaller manual transmision,it is a short overall length.nissan produces larger trans of the same length,they are easy to get in this part of the world many modify there cars to fit the longer trans i dont know why.also colum shift is available.small gearboxes of the same type you should have are available in japan to suit CD/LD engines into a 510.good luck finding one.

LD20II and CD20 only come with the oil pick up at the front.i believe there are crossmember modifications including reversing the member to fit these engines.i havnt had a look-i know itas easy in a 120Y.

clutch fork and thrust bearings are a match to the pressure plate/flywheel..
there are many types.

Holy replication Batman.... that IS an L16/18/20

Where do I get one of these. That is exactly what I am looking for.


Where were those pics taken?

LD20s weren't sold in an automotive application in the US.

Those pics were of a JESCO auction in California in July (search in Peddle forum for the whole thread). There are a couple of importers bringing them in, notably AJ @ "exportintl" on eBay. Do a search on him before ordering anything from him.

You want an LD20 or better and LD20T, it sounds like.

The LD20 didn't come in the 720 for a short time? Was that only an SD application?

Yes I want an LD20T.

I talked to a guy at Jesco and they have them new for $3200...ouch

He said he had a used one (turbo) that was priced at $1200... seems a bit high but considering the availability...

Well If ANYONE knows where there are some LD20T engines... PLEASE let me know.

That engine looks like a direct bolt-in swap...hopefully.

Did the LD20T get imported into Canada at all?

In the US, the 720 only got the Z2x and the SD2x engines.

AFAIK, Canada didn't get the LD20(T) in any automotive application either.

$3200 for a new, complete LD20T is a very good price. Heck, I'd consider that if I had a project that needed one. And $1200 for a complete used LD20T, an engine that you won't find in a JY anywhere in the US, is also darned reasonable, IMO.

If your budget won't stretch to $1200 for that one, maybe you'll have to stick with a Toyota L or B series diesel, a Ford/Mazda/Perkins diesel, Ford/Mitsubishi diesel, or Isuzu/GM/Chevette/Luv. Or the ubiquitous VW 1.6/1.9l stuff.

None of those will be bolt-in. The LD20(T) looks to be basic plumbing only, all the hard parts are nearly bolt-in.

If you get a 720 SD engine and trans, you can swap the front case half of the SD trans onto your 510's gearset and rear half, and then fab the motor mount points. You shouldn't have to rework the driveshaft and carrier bearing mount in that case. It'll then be plumbing from there on. But have you ever driven an SD? The engine drives odd, at least the ones with pneumatic governors that is pretty much all we have in the US.

Of the two, for a swap, I definitely like the LD engines over the SD. I'd sure like to drive something with the LD20 installed. I drive an LD28 daily.

If I go with the LD20 where can i find parts for them? i.e. gaskets... especially the head and intake/exhaust?

I don't like the idea of the SD at all. Too much to change. Nor do I like the idea of a different mfg. again, too much to change.

The $1200 is not bad considering it is a turbo.

Is there a contact in the US or Japan that will sell parts for the LD20? If I wanted to rebuild the LD20 can I get pistons for it? I assume you can get them for the LD28 and the should be very close if they are anything like the gassers.

A gas L20B is the approx. the same as a gas L28.

The 510 has no carrier bearing for the drive shaft.... it has a one piece. Is that a problem?

The problem with the SD is that the starter is on the left side and a 510 has a steering box on the left frame rail.... they are bound to hit.

Looks like an LD is the only way to go.

I wonder what it would cost to import one from AUS or Japan.

Good Q. Overseas, that's for certain.

I agree.

The LD28 uses 84.5mm bore; the LD20(T) is 85mm, so they don't interchange. However, read this thread about ArcoMotor. I've put in an order for some SD piston/ring/liner sets, and they should be arriving any day now. Cheap parts, expensive shipping, but they can be had:

LD20T piston/liner/ring set LKNI408503PB at ArcoMotor (no prices). I have determined that "one set" is all the parts to do an engine, in Arco-Speak.

Other parts would probably have to come from somewhere outside the Americas; our member davehoos in AUS can probably give some pointers.
The 510 has no carrier bearing for the drive shaft.... it has a one piece. Is that a problem?
I'd forgotten. No, it's not a problem.
The problem with the SD is that the starter is on the left side and a 510 has a steering box on the left frame rail.... they are bound to hit.
Hmmm. That's the same situation as in the 720 PU, and clearance isn't close to being a problem. Actually, clearance is good. The SD is not particularly wide. But the oil pan is oddly shaped. In fact, you will want to check out the oil pan shape on the LD20 too.

I saw a VG30 stuffed into a 510 last year. If you can do that, you can do anything.

ODD? What's so "odd" about having all torque at low RPM, no horsepower, no turbo, ... and needing 6 or 7 speeds behind it? :wink: :)

So I take it that when you rebuild a diesel you don't bore it 40 over... but you replace the sleeve?


I have a 510 wagon that I put a VG30 in... It was fun.

There is a guy that sells a kit for it... it makes it a direct bolt in.

Sounds like it was, it probably went decently quick with 150 hp in the tiny 510

Much like how I keep saying I wanna put a SBC350 into the maxima, but im waiting till 300k for that, when I get full usage out of the L24e, no reason putting down a perfectly good motor just to go fast.
