Turbo classification...?

[tm america]

wow this has me scratching my head my motor is a ldt1d according to the tag but it has a lds turbo on it according to the pics from dan martin ,it is not like the ones labeled d or c since the compresser side is way thicker than those .it doesnt hardly whistle but i am getting about 27psi of boost with my fuel just turned up to where i am getting black smoke .i have been beating on it for alomst five years and not blown it up .is there a chance i have a miss labeled lds motor or a ldt that was rebuilt to lds specs.my truck was depot rebuilt in 92.i will take some pics tomorrow

Unless it has a wastegate, it's probably and LDS427 turbo. The exhaust side of the gated turbo from the LDS-465 is much larger than the other turbos and would require serious exhaust mods to adapt it. There is a data plate on the compressor side that kinda sits at a 45 degree angle sorta.

 

[tm america]

it doesnt have a waste gate it is like the one in the pics dan posted with the think compressor side. i will get the numbers off the tag on the turbo

 

[Recovry4x4]

That is an odd setup for sure.

 

[tm america]

ok here are the numbers off the turbo 3ld305j3072-48 and 11663392

 

[tm america]

it is a swhwitzer turbo

how do you turn up the fuel on the injector pump. my truck runs fine, but a little more peddle is always a good thing.

 

[tm america]

do a search for turning up the fuel

I have the 427 lds turbo.... shes a good turbo I like it alot...when we first met she looked like someone left her in the bottom of the pond for 20 years...but Mr.Ken fixed her right up in no time....now she runs like new and blows more air.... I with there was more info on the lds turbos and how they compair to the c nd d turbos when you up the fuel..also in the stock form....anyone have bench flow charts for all 3?

Is this the turbo you all are talking about? I have it on a 109 with the LDT-465-1C.

 

[tm america]

that looks like it but it doesnt whistle .and my motor says ldt 1d on the tag.was the m109 rebuilt in the 90s i wonder if they built them to different specs around that time .and maybe these turbos were a upgrade .or if they did them to lds specs .whats funny about these turbos is the exhaust side is similar to the c turbo but the compresser side is similar to the five ton turbo.all in all it looks like a five ton turbo.mine says swhwizer right below the tag .can you check to see if yours has the same tag numbers as mine

 

[tm america]

recovery4x4 were you able to fine anything off of the tag number from my turbothis is really interesting since it would mean they actually ran three different turbos on the deuce not just twoand this turbo i have seems fas superior to the other based on the boost readings everyone is getting with the fuel turned up.there are a couple guys that said they had readings similar to mine but most have 11-13 as a max .i wonder if the ones with readings higher than 20psi have this same turbo as i doi would like to get some more info on it and if they did internal mods when using this turbo

 

[Divemaster920]

I just checked and the part #'s are the same.
The serial # on this one is 3LD-305/E2472-45

 

[tm america]

i dont have a lds maunual to see if they are in fact from a lds427 if anyone can look up the number to see if it is or not that would be greatly appreciated

 

[tm america]

divemaster920 does your turbo whistle like the c turbo does mine just barely gives off any whistle

 

[Divemaster920]

Tm for the 427 turbo is 9-2990-201-35....I looked in the TM's and it is not there.
According to the pics in TM 9-2815-204-35 (427), this is one of the turbo's that it used.
No, mine does not whistle like the "C" on my Deuce, but it does have a faint whistle to it.

 

[monkster]

With out doing any search. Are these turbo' rebuildable, say from my tractor mechanic.

 

[Crackerjax]

yes the fat compressor skinny turbine turbos are lds 427 turbos from what i hear they are rare....oddball turbo...mine runs 9psi of boost on cold day at 50mph gas to the floor..but my truck is stock. I can hear a faint whistle at idle and more when boost builds.I hve taken the upper part of the stack off for painting and it seems to spool up quicker with less exhaust pipe on the stack....ken knows alot about these turbos it seems like...he did a great job on mine

This is a pretty old thread to still be pinned. I've rebuild a C (whistler) turbo but is there a rebuild kit available for the D turbo?

 

[Gypsyman]

If I read this old thread correctly the answer is no but that may have changed. Still a great thread to read through. I'm surprised that it isn't pinned.
