- A rare 8V53T, (factory turbo), Detroit making some noise.
I was standing about 20' from it holding the camera, and wishing I had two more arms so I could stick my fingers in my ears, painfully loud...

after all these years of watching detroit diesel 2 stroke engines, this is video is still in my top 5. (and I still watch this one for about 5~6 years now. One day I will find and score one of these rare 8v53 engines for a little 1966 medium GMC truck project im working on.
Please tell me you found one, I would love to see this
Yeah they're scarce as hens teeth I mean for a good deal anyway. I wanna put a 6v53tt in my 02 Toyota Tacoma 10 speed Allison 4 speed transfer case Rockwells and steering front and back plus pinion brakes.
In the late 80s-early 90s, there was an organization called GATR (Great American Truck Racing). They raced single axle versions of American class 8 tractors on NASCAR tracks. They used Detroit (GMC) diesel engines exclusively; at least the successful competitive teams. The reason for this was greater potential for horsepower and RPMs than other makes, with a lower cost. Engines ran in excess of 3000 rpms for hours during the races and stayed together. So, when money was the reward, Detroits were used. Kinda makes you go "hmmm".
It's used in the LVTP7 (USMC amphibious vehicle), is 2 stroke diesel and developed 400 hp@2800 RPM. It was replaced at the end of the 70' for a Cummins 4 stroke, 400 hp@2800 RPM. It was a good engine, but his maintenance was hard, specially when you had to calibrate the governor. The turbo benefits the 853 due to it have more air in order to keep the cylinder head colder and to do a beter cleaning of the gases after de combustion cycle.
Armando Vittorangeli I wonder if it would have made 600hp like the 6v53 makes 400hp now that it has electronic injection etc... on the military version.
Interesting...They replaced a 424cid Detroit 2-Stroke diesel...with a 903cid Cummins 4-stroke diesel...and supposedly gained 125hp... Also interesting how the military has engines "turned up" and don't care because they are throw away units.. The V903T in semi trucks where only 300-350hp and military had 525hp...I think the 903 comes in 600hp variant NOW!
@@misters2837 i work on A fore mentioned Vehicles...... im an Operator.. The Cummins VTA 903 T Big cam in the AAVp7A1 ram/RS Both P7 and C7 vehicles the Engines are downrated for our transmission the HS525 with the hydrostatic steer unit.... in other applications and a different governor the engines make well in excess of 1000 horsepower in exactly the same configuration. our engines are downrated to 500 hp + - 25 hp. but i got bored today and decided to look into the Previous generation of the AAV and i had thought they always had a 4 stroke cummins 903 variation in them. No idea they had a badass 2 stroke Detroit in them.
Thats amazing! Didn't know there even was an 8v53.. Very nice
What an Animal!..I used to dyno these 53 military motors yrs ago....killer fun
When not installed directly in GM vehicles they were referred to as Detroit's for a time before ultimately changing the name but you could find them with GM Diesel or Detroit on the valve covers in the same era for a number of years.
Yea, all Detroits have blowers on them. They won't even run without a supercharger.They still consider it naturally aspirated unless it has a
turbo(s). Gotta love a Detroit
Painfully loud...Fuck yeah! Doesn't it just feel so good?! Not to mention sound good. I've never been one to plug my ears to suppress the sound and power of a screamin engine, reguardless of the make. Its amazing I still have hearing, and quite good, I might add.
It's not my engine, but I trust the owner (runs a well known Detroit Diesel repair shop) when he says it is the big injectors essentially flooding it on start up.
I have a 4-53T with the low compression pistons and 5A65, (or are they 5A60?), either way, it will start before you can let off of the switch. So, it's not the lower compression making it hard to start, it is the injectors.
It's actually the injector heights they run on bigger injectors you can advance the timing a little by tightening them down a little and they start easier but lose a little fuel at full rack. That's what we do with the 100 and 115 injectors in the 92 silvers
very true! we did a 3-53 for our skidder and i followed the book setting the rack. we talked to lots of ppl and they all told us te be ready for a wild fire up. so happens when it fired it just took off wild, but we got it shut down before anything came apart, just blew the gasket on the oil cooler but that was due to a block maching defect. i looked the book over again and on the next page of the gov setup, it mentioned the part about backing out the gov screw...hehe opps
wow that's a rare find! first time i've heard a 53 series with 8 cylinders COOL!
They are EXTREMELY rare unlike the 8V71 and
8V92's - the 71 and 92 Series are easier to come by though!
Mostly to do with larger and heavier parts swinging around in there. Pistons and rods and such have to be stronger/heavier to withstand the pressures generated during combustion, starting off with a compression ratio from about 17:1 to 21:1
Small diesels can and do turn fast, because the parts are smaller/lighter.
I know this video is ancient, but for anyone stating that Detroit was not made by General Motors, why does my 4-53N have General Motors Diesel stamped on the valve cover. End of conversation.
Pick up a newer manual for your engine and read it a few times. Then find a friendly Detroit shop and or mechanic to answer your questions and explain the confusing parts. The manuals are really good.
Back in the day I heard that some truckers got them installed in their rigs. They liked the fact that it was a small and light weight engine with plenty of juice. I am guessing that that engine can out put 340-350 HP and 810 ft/lbs.
DUDE! it sounds like a chevy with no exhaust! i love it!
Damn, those Detroits sound awesome
2 stroke? sounds like it, it's a monster!
talk about throttle response. and for a diesel? daaaaaamn. very nice
They only made about 7,000 of the 8V53 engines, and very of few of those had a turbocharger from the factory.
Just you fellas wait til I get my "baby"! I'm getting a 4-71NA industrial fan-to-flywheel with (not too sure of the injectors) either
N60 or N65 injectors off a mate in Albury!
it probally sounds even better by it because camera cna be quieter i like that sound of the old detroit's
No, not exactly, but the 4-53 does share many parts with the 8V53, including cylinder head, pistons, and lots of other small stuff. Each engine also has a bunch of parts that are specific to it only.
I have 2 x 8/53 on my ship.. Real monsters... Love them..
Are you from New Zealand?? There were boats in the US called Hattaris with Detroits. How big is your boat and top speed. Cheers from Australia.
@DeserTBoB93535 we had 6v53`s that usually ran N50s and ran N65s in them forever. Nice boost for a small motor with a bit more smoke. (BTW if you where`nt careful perhaps a piston LOL)
Wow that old Detroit roaring like a lion Yeah !
im not sure about the 892, but most detroits are relatively simple, most peoples issues are with setting the fuel rack, which is best to be thoroughly researched, or hire someone to do it.
:D I want to put this bad boy in my truck...damn it sounds sweet.
Just guessing, but at Oshkosh you probably have 8V92T engines for military use?
did you get this engine from a private owner or some sort of gov liquidation site ive found plenty of marine style 8v53's but i want a military version and is it true the military versions have glow plugs not either start thanks in advanced
GM owned Detroit when Detroit designed and built that engine. As GM owned Detroit at the time, that makes this engine a GM design.
Is that an exhaust driven turbo charger at the top? Will a 53 series benefit from that?
Ow, so the bigger the engine the less rpms do to the mass. Are Diesel engines blocks built any different than gasoline engine blocks to hand the strength?
They are governed at 2800 max from the factory, that's not high for the engine size/ bore & stroke.
This engine is very responsive because it has almost no flywheel on it, just a ring gear/flex plate, the torque converter it should have would be the rest of the flywheel.
@Xx69roadrunnerxX Mainly because diesel is slower to burn than petrol.
He says "It has N80 injectors in it, so it starts HARD."
Loud & sweet!
What would be more econmical an 8V71 or and 8V53. I understand that the 8V53 is roughly about a 6.9L
First off, this is not my engine.
I understand it is/was military surplus.
No, the 8V53T does not have glow plugs.
What you're thinking of are the newest military 6V53T's that do have glow plugs
Economical in what?
As far as replacement parts the 71 is lots more common than an 8V53. Although the 8V53 shares a lot of common parts with the other 53 series engines it also has a whole bunch of special only 8V parts, which will be difficult to find if you need anything.
thats a rare treat a sweet sounding 8V53 Detroit anit many 8V53's running & that good of shape ..
my hats off to job well done of keeping a piece of history alive
What was this engines application...hets...henmmits...arty peices...m109 ect.......what?...its only a 53 inch per cyl engine?
That is soooooo AWESOME!
nice Engine, sounds cool and wild. is it 2 stroke??
i wanna strap that thing to my snowblower..
He's right it is.
Why are Diesel engines governed to such low rpms? Is it so they always make max torque or am i way off?
Hi grigg, read a post on the 4bt site you were in but haven’t been able to register to the forum. Saw that you at one point owned an 8v53, do you still?
ok thanks what is this going in and how much power did the turbos add and where did you get them
No flywheel, just a flex plate with a ring gear. Flywheel or torque converter will slow it down some...
Will it fit my prius
I have two 8v53's in my boat. The engines sort of growl.
can break any driveline hooked up to it thanks to savage 53 series power delivery
most modern deisels are only running 15 to 1800...and those detriots....only run about 2000 in practice. They sound like 4000 because they are cracking every stroke insted of every other stroke.
@o56kid...It was General Motors Diesel Engine division until the name was changed to Detroit Diesel.
Don't know what year DDC was sold, but it went to Penske Corporation before they sold it to Daimler AG who now own and operate the engine manufacturer to this very day.
Hey grigg how much diesel and hour does a motor like this use?
that camara dosnt do it justice. let that GM Power sing.
Does that include all the military ones?
Best I can tell.
Of course it's two cycle!
Is that the two stroker out of an M-113?
Wonder if one of these will fit in a old Chevy c-30 minus the turbo
If you can fit a 6.9l engine in it and strengthen the frame then i don't see why not.
I'm doing a 6v53 is an '81 c-30. I'm keeping the truck stance low and to this I'm replacing the A arms with a drop axle on leaf springs. If I could find an 8v53 I'm sure there could be room for it with this setup. I don't think I will be cutting the fire firewall for the 6v, however an 8v might need to sit back into the cab some. These are rare as heck to find so I just decided to move forward with the 6v53.
2800 for a vehicle
2500 for industrial, usually continuous
the excessive smoke is due to the large n 80 injectors
@jaggass plus the 53 series are aluminum blocks, not cast iron.
That isn't true at all... only some of the 53 series is aluminum and even then only in specific applications and are relatively rare. Most are still cast iron. Some of the 71 series are also aluminum.. but yet again uncommon.
N80 dont make it hard. Its the lower comprssion turbo pistions.
My high preformance 353 will move my PU fast.
A 853 would be a dragster. cool motor to put in a PU truck
Sounds like its revving up to 7000rpm but its only 3500rpm.
What are the dimensions of that engine would it fit in the same space of a caterpillar 3208
yes it will fit
Detroit diesel used to be Owned by GM. the @ stroke diesels are General Motors Diesel
what is he saiding at the start of the video
Detroit is a Gm motor noobs is a
Two SSsssTRooke Motor haha too nice sound
Is this for sale?
between18.51 to 22.1
Sounds like Eric1978 needs to do a little research before he shoots his mouth off...
It should be governed at 2,800 rpm
2,800 rpm max governed by the factory. Some folks run them faster, I would not.
does anyone know the hp and torque ratings on these turbo and n/a
The 8V53 natural was 247hp @2600 RPM with 45mm injectors. God knows what this thing puts out with a turbo and N80 injectors. Somewhere around 300 + hp.
throw it on to a load cell make around 200 hp but about 1000ft-lb.
Sorry bro, not here. Im an 11 yr. Detroit Tech. The two strokes have not much bottom end. Its all hp at the top. FYI the factory gov will load up to 3200 rpm.. you can safely get 3800 rpm with adjustment and about 4200 with stiff valve springs. Like i said its all up top thats why Detroits are always operated to the top end. they are not low end torque r's
+Andrew Karpinen Why do 2 strokes only have all the power at the top end? is it to do with the cycle of the engine?
Andrew Karpinen the fuck are you talking about? and yes you can get them in a high RPM band but they dont make more power at higher RPM.
+Trent Nelson yes they do.
+michael jagger yes sir, to put it simply as possible here in the comments the Detroit type two stroke is very inefficient at low engine speeds. As they require a blower. ( yes this is the original Roots type and it is where people used to get them off of to put on top their Chevy. ) This Blower is simply used to purge the cylinder of spent gasses to allow for start up. They are not desighed to supercharge the engine, only build a positive air box pressure. however on our Dyno they do usually produce 2-4 psi boost pressure. As the engine revvs higher the exhaust velocity is then able to effectively scavange the cylinder gasses. Fyi, a non turbocharged engine even with a blower is referred to as a "Naturally Aspirated Engine" . ...Now on power production, (and of course ther is an upler desighn limit and physics of course ) to put it simply the mor "Putt's" You can get out of an engine per min. the more power you will make. Also note I said Power not torque. The power produced is proportional to the amout of fuel consumed over a defined period of time. Great example is Formula 1 cars. spin the engine 18,000RPM! and you will make all kinds of power. on the subject of 2stroke diesel vs. 4stroke diesel, basically a two stroke diesel is able to breathe very efficiently the higher you revv it. to a desighn limitation point of course, the 4 stoke power curve is entirely dependant on the camshaft profile.( mostly, fuel curve and profile 2nd. which are desighed/programmed around the cam profile ) hope this sufficiently answers your questions. Glad to explain it.
as in miles per gallon.
No, it is not my engine either
How can they breathe and inhale all that toxic poison exhaust fumes???!!! 😷😷😷😷
Wrong again, princess.
General motors FORMED the company known as GM diesel in 1938. In 1965 the name was changed to Detroit Diesel. in 2000 they were bought out by Daimler/Chrysler.
GM DID make that engine, because GM was the parent company of Detroit, just like they are the parent company of Chevrolet, Buick, Pontiac, Cadillac etc. The ID tags of Detroit engines have a big GM logo right on them.
Like I said before, do your research before spouting off about shit you know nothing about.
Its a detroit diesel not made by GM.
My God, that sum-bitch sounds just like a warmed-up Chrysler 440 big-block!
What's max (governed) rpm on those? I've heard some say 2800, others have said 3200-3600 (that last would be very cool, to say the least!)...
