ld28 what do you know about this diesel

[anth]

I in the middle of planning a new project just picked up a ld28 diesel and 3sp jatco, have been doing some research but cant find alot about there weakness strengths ect.........So does anyone know anything.

I have heard the 280zx turbo manifold bolts up with some modification,but they seem hard to come buy so does anyone make flanges to suit?

 

appreciate any help

                                cheers anthony

Many people use the crank of the ld28 and install it in a L28 to make it a stroker (3.1etc)

 

The ld28 head does not have injector notches but do share same mounting of manifold iirc.

It is also a sleeved motor that can not really be bored out - block is approx. 17mm taller than L28

 

Think I have an engine workshop manual if your intersted

[gav240z]

Basically the only good part for our Zs is the LD28 crank.

Cheers Guys

 

I would be interested in the manual for sure,

 

do these engine have  any real weakness maybe rod bolts/.rpm ect,

 

will any of the turbo manifolds bolt up or only 2.8 from the 280zx ?

 

its a project,something different but should be fun, the motor is the first stage ,and the hardest part is finding the information as there not that common.

 

appreciate the replys

Somehow I knew these videos would be useful someday.

 

Not an LD28 but a diesel turbo in a 240z.

As for your questions I don't know if a turbo L28 exhaust manifold will bolt up, I believe the head is unique on the LD28 motors. I've seen this motors put in everything, old Holden's, 4x4s and even Z's as you can see above. I would say the weakness will be the weight of the rotating assembly.

 

I often see them listed on trademe.co.nz

 

Perhaps Nzeder on here can help out, he seems to know a bit about them.

the last datsun runs a om606  mercedes diesel which i looked at dropping into our diesel merc but at 6,500 aus compared to 800 euro it was little too much,there a 5 cylinder direct injection the std bottom end is good for 900nm and close to 600 hp on 3-5 bar.

 

I guess i will see what this little motor can/will do it's a nissan 7 bolt main so thats got to be a good start........

Quite a few of the aftermarket 4x4 accessory shops did kits for the boxy MQ Nissan Patrols, running these engines in atmo form, a complete bolt on low pressure turbo kit, but you're talking early to mid 1980's and could be hard to find the kits.

 

A turbo exhaust manifold ex USA running the old T3 or T4 Garrett, into a blow through carb was the usual.

A bit more modern would be a injection intake complete off a 280ZX as sold here, in Aus, at low 5-7 psi, no intercooler, would not stress the LD at all.

 

It is a slow revving torque monster, dont expect snappy gear changes or breakneck push in the back acceleration.

[anth]

The inlet manifold is similar to the 280zx just with out the efi,

My plans were to bolt on a turbo I have and modify the the pump,

the options i have is mill up a flange and make a turbo manifold,Find a 280sx turbo manifold and machine it to suit or run a J pipe off the cast manifold.

 

Thanks for your help . I think it will be a matter see what happens,

age is a limiting factor as Ld28 aren't common here compared to the sd33 or td42 mosr 4x4 places local haver not heard of it,The wrecker I bought it from didn't even know what it was and it took him a day to think of the price.

 

Cheers anthony

The crank alone is worth $800 - I hope you got a good deal!

I'm interested to hear why you're choosing to go the turbo diesel rather than petrol..

[anth]

G  I have played with petrol I want to do something different for change im bored i have played with boosted petrol(carb), Tuned boosted 85 (carb), have done lpg

I have been impressed with how tough the nissan series engines are  "A" and "L"

So the  ld28 is based on a l series 28 thats got to be a good thing ......It a project at the moment , I have also spoken to a engineer and he is happy with what im proposing just the donor car is the issue........I no longer have a z

I would love to get another but I don't have the room or coin so im using the cheapest option to me another roller non nissan

 

I bought the engine and box because at that price i couldn't turn it down

Hi Anthony

 

I am a big fan of Diesel power and will be following your progress with much interest.

Do you know how much more the LD28 weighs compared to the L28

 

Cheers

 

PB

[anth]

I think its about 230kg........

 

If i decide to change my mind as I do sometimes would there be any interest in buying the complete motor and trans..?

 

cheers anthony

[gav240z]

If you change your mind I'd probably buy the motor for it's crank lol...or convert to veggie power.

Thanks, and yes I reckon people would be interested in the motor, even if just for the crank 

[Riceburner]

I'd be keen for the crank too

[gav240z]

Just some links to show that in NZ they put them in anything / everything.

This guy claims he has lots of LD28s

Perhaps we should ask him to send over several cranks and split the freight costs?

[Riceburner]

What would freight be on 50kg's? Assuming two cranks + packaging

[anth]

Most will frown,

 

The car im considering is my Xb gs 6 cylinder  it had it's engine taken before i bought it that's why the engineer approved it the best part with the diesel conversion is the car has to comply to the engine and since diesels doesn't have any real pollution im limited to noise which being diesel falls under commercial so it's all positive

.....Veggie power is good we have ran i Mercedes 300d on it for 4yrs no issues have friends with boosted  nissan sd33 4x4 running 18psi straight veg oil no issues its great stuff but messy to process

 

I wont start a build here because it's off topic to the "Z" I was chasing advice,but I will do a Engine build because that's on topic

as I stated if it goes tits up i will sell the lot together for what i bought it for.

 

Cheers to all appreciate it Anthony

 

[chris240]

You want to put a LD28 into a falcon XB ? 

Noooooooooo !!

[anth]

Why not......it's not like it can't be changed back....they ran nissans in holdens.....merc's in z..... most 32 hotrods have 350 chevs in them....

 

it something different and it has been done before

[gav240z]

This latest MCM post got me thinking about LD28s again.
