has anyone here done this? ive got a 66 starfire that would prob fit that pretty easy ? and I would like to turbo it any thoughts????I see these full size trucks going 11 to 12s easy and getting high mpgs.....

As a matter of fact, Oldsmobile did it and it did not work out too well.

Its not a walk in the park but the 4bt cummins or maybe even a 6 bt would be do able. The 4bt's in delivery trucks came with th400's so the bellhousing adapter could be used for the 6bt. If you use the older 4bt\6bt with mechanical injection your electronics would be kept to a very small minimum. Anything is possible its all what you wallet and mind allow. My friend did a 4bt in a k5 blazer. It makes enough power to tow a car with ease and gets 29 mpg city and 33 hwy that's what he claims.

Fastest thing at the racetrack last year was a farm truck diesel
Huge clouds of black smoke, much fast go.

I will venture to say it was very turbocharged, and you won't get that from the Olds diesel, for long.

For the cost and time involved it would take ages to get your money back in saved fuel. Plus you would have a non standard car worth less than when it was in original spec.
A late DX olds diesel will drop in without many mods and should be reliable, but not a lot of use if you are ever in any kind of hurry........

To be honest you can pick up a 6bt with appx 180k in my neck of the woods for about 1800 with the injection pump.In reality those engines will run well over 450k with no issues . I had an old dodge ram with a 6bt I bought it with 170k and sold it with 320k and broke even.

I have read that the cummins 5.9l (which I think is tha same as the 6bt) is capable of making up to 1200 hp with no bottom end mods. You could easily get 300+ hp and probably over 500 lbs.ft of torque with bolt on mods. It would sure turn heads at the strip.

That would be a fun project, lots of fabrication. You'll need to beef up the front end.

If you're making room for a bigger, heavier engine, why not just go for one of these:



Only 1,400 pounds!

You are not thinking about olds 350 diesel, are you???

steve walker

no not a older one . but like a 2004 or newer duromax with turbo

coppercutlass

The older 5.9 6bt cummins with the p pump would be a much easier swap to be honest. No ecu needed to run it . Same for the 4bt . Imo the cummins will make more power and hold it easier than the duramax will in terms of modifications.

chadman

I disagree on the Cummins making more power than the Duramax with similar modifications. I do agree though that it will hold more power reliably in stock long block form. That said, I have a buddy with a 650rwhp stock long block Duramax that kills all of the Cummins trucks in his class at the local pulls. That is about the limit though without upgrading rods, head studs and head gaskets. Here is a video of him winning a local pull back in August:

While those GMC V12s are a gnarly-looking engine, they got about 3mpg is why Diesels supplanted them for OTR tractors. There's several youtube videos of them running. Nasty sounding beasts.

coppercutlass

chadman I phrased that worng lol but you essentially explained it better on how the cummins will hold more power in stock form internal component wise .

Hey Steve just saw your [post.
I'm Presently putting a 2007 Duramax LLY motor with a 4L80E in a 61 Dynamic 88. They aren't as tough as some might think. There are 2 companies the make a stand alone wire harness for them. Its certainly not a cheap swap but these motors when dialed in with moderate tunes run awesome.
We were originally gonna put a Ford ( International ) 6.0 from a Super Duty because its not as tall as a Duramax but the wiring was a nightmare.
Cummins 6 cylinder are too heavy but do run great.
The Duramax are considerably lighter. Only 85 pounds heavier than the original 394

steve walker

hi kx1233 that's what im talking about . Ive seen one in a chevelle ran high tens and got 22 mpg stock bottom with mild work done .the new stock gms are about 400 hp and 800lbs tq .. so what kind of price range are we talking about ???

kx1233

Steve,
Cost are $4000-$6000.00 for motor and trans,$1000-$1200.00 you should also try to get the all of the original wiring harness from the bulkhead connector back to motor as you can, there are some items that may be needed when you have the standalone harness made to your specs, its pretty simple.
Also the gas pedal will be needed for the drive by wire setup. There are also a few streetrod companies out there that cater to gas pedals. You should also try to get the intercooler if you dont want to upgrade to an aftermarket one.

Supposedly the later Olds diesels did have most of the bugs worked out of them. One of the many problem was the factory head bolts were not strong enough but rebuilders solved that problem with higher strength bolts.


Of course it didn't matter what GM did to fix that engine, its reputation was destroyed forever.

cherokeepeople

alot of the 5.7 problems came back to bad fuel.and using the customer as a guinea pig.after they went to the dx block pretty much all lower end problems were solved.but still had bad fuel the water separator was a joke.last one we went thru we replaced the head bolts with studs,which they should have done in the first place.if you want one a buddy of mines dad just died he has my old 79 toro we did the head gaskets and bolts on it bout 7 to 8 yrs ago.has a beautiful 84 buick lesabre 2 dr with probably 80k miles.has an 82 park ave 4dr,and he also had an 82 toro don't know if he still has that one.located n.w. iowa i'm sure they will be getting rid of them as for when?
