Anybody ever think of doing a turbo diesel conversion to an ohv? I've been thinking all day I'd like to do something like that to save gas on my sunfire. I spend $30 a day on gas... and into the summer it's going to get up to $35+ a day.
I'd like to see 40+ mpg. using 18-20:1 CR.
This has never been discussed before... surprisingly enough, not even by newbies.
I don't expect to see much HP at all either. like 120bhp (pretty much around stock)
I think in the states... you guys have some legal reasons and such.
What do you guys think?

1) That's because you're in the boost forum. Using a 2.3 as a diesel was discussed in either the performance or tuning forum.
2) You're being downright silly. Buy a diesel. Don't try to kill a poor OHV engine by asking it to do a job it was never intended to do. Think Chevette (Isuzu) 1.6, Isuzu P'up / Chevy Luv 1.8, or Toyota 1.8 for a source for your engine.

converting a gas engine to diesel is one of the worst ides ever. just ask GM. they did it with the 6.2L v-8 back in the 70s or 80s. it was nothing but trouble, and has been listed as one of the 10 worst engines ever made. nuuf said right there...

get yourself an older jetta TDI, it'll be cheaper and more reliable you can pick one up for around 2K if you get a mid 90's or earlier.

so you mean to tell me you drive upwards to 300 miles a day?
You won't be able to convert your vehicle to diesel. You would be better off buying a flex fuel conversion, swapping the motor completly to a diesel motor, or buying a new car with a diesel motor.
Easiest, is to sell your car, and buy a VW golf/Jetta with a diesel motor.
Moderate, install a flex fuel conversion. that way you can use regular gasoline, or E85 blend.
Hard, swap the motor with a diesel motor. You can buy adapter plates to mount a diesel 1.8L Chevette motor to the Getrag tranny. Then you just need to fab up motor mounts and a fuel system. If I rememeber correctly, the 1.8L motor was actually a Isuzu truck motor, which was pretty durable. You should also be able to make the 2.2L Isuzu diesel (from a 83-85 Blazer/S10) work, if you can find one.
Along with installing the diesel engine you'll have to figure out what to do to handle the vibration in both the drivetrain and the car. Diesels are really harsh that way. And with a 3rd gen J you'll need to figure out what to do for gauges since the pcm will now be worthless. I once wanted to convert an 82 Cav to diesel using the Chevette powerplant, but that car was a carbureted simpleton compared with today's vehicles.
Besides, there are plenty of ways to save fuel even with a gasoline engine.

Ummm actually it was a 5.7l engine built from an Oldsmobile gasoline engine. They also built a 4.3 V6 diesel. Both were self destructive. The 6.2 was a gutless pig, but it was much more reliable than the 5.7L engine.

ah, i stand corrected on the displacements, however..i was sure that GMs gas-diesel conversion was a major flop.

I think the VW diesel and the gas motors are the same except for the heads. but then again they converted from diesel to gas and not the other way.

Well, interesting to note is that although GM failed miserably to convert the Olds gas engine to a good diesel, Joe Mondello and a few others built killer drag engines converting the converted Olds diesel engines back to gasoline. And the farm boys figured out that they could pull the diesel heads and intakes from stock engines, replace them with normally low compression gas heads, carb, and intake, and they'd have really strong gas engines which would live for years.
Which only helps show how diesel and gasoline engines are really different animals.
-->Slow
Slow took the words out of my mouth. The best block for a killer small block build IS the diesel blocks. The biggest problem with the small block diesel was blowing head gaskets. Many people put in arp fasteners and they make for a reliable diesel engine, gutless? Yes, but they are fairly reliable.
I was just pondering about it... and obviously i don't know much about diesels because I was never able to work on one. but I did drive my friends sierra 1500 diesel. I was like: "hell yeah!" I actually felt like I was the king of the road, and could run over all the small cars under me.
my manifold-downpipe gasket is crap on my sunfire. it souned like the truck... so while i drove, it just got me thinking if anybody could do it.
when i seached yahoo all i got was stuff like this: "can i convert my XXXXXX to a diesel" answer:"buy a car with diesel"

diesel engines usually are very strong, internally. they have to be, they run enough compression to ingite the air/fuel mixture from pressure alone. 17:1 compression is not unheard of. and add 20+ puonds of boost to that...takes some strong rods, pistons, and crank to hold that kinda pressure.
and i know what you mean about the chevy 1500's. we have one at work..regular cab, 2wd, regular bed, 2500 duramax diesel with the allison automatic. im sure its around 4000 lbs, but 510 ft-lb of torque makes it jump on the low end...falls flat on its face around 70 though...
but on the other end of the spectrum...i beat a dodge cummins diesel in my girlfriends old escort gt automatic...guy drivin hated it, his buddy in the passenger seat was crackin up though...

But on the other hand I had my arse handed to me at the strip by a Cummins diesel running 12's Couldn't see the track for all the black smoke, but when it cleared he was at 12.2, 12.3. They're winding those engines up a whole bunch these days.

The diesel chevette ironically was the Isuzu 1.8, and the Olds diesel was based upon the gas engine
arcatechture and pretty much perfected by '81 with the addittions of a fuel/water separator, fuel tank heater to prevent
low-temp fuel parrfin separation and hydraulic roller cam to prolong oil change intervals by reducing cam wear
caused by a combination of corrosive diesel blow-by comtaminated oil and flat-tappet lobe/lifter surface loading. But the die was set by poor diesel operation/maintainance understanding by most end-users and dealer/shop servicefolk topped-off
by 2-yrs of owner problem/complaints on a large scale. Buick also toyed with a diesel in the same time period with
the same results. It should be noted that the block/crank combo of the Olds and Buick V8s & V6s make the basis for
durable reduced-cost hi-pwr gas engines for which they make conversion kits. As for the GM/Isuzu 6.2, Banks makes a
turbo kit for it that improve power and economy.
P.S.: If you find a Buick diesel engine, block and/or crank w/or w/o rods,
GRAB IT! They're worth gold to old-school Buick guys!
Go beyond the "bolt-on".
Oh, one last thing...
The S-10 platform came available with a 2.2L diesel from '83-'85, which was also a Isuzu design I believe.
But not the same as they placed in the Chevette, available only during those same years. Finding one will be
just as difficult as finding any other diesel assembly I mentioned, except perhaps a GM/Isuzu Truck 6.2L, as
america's common driving public had mostly developed a distaste for the nature and quirks of diesel prior to
those model new-sales years. And the Chevette, well... do this math:
Gasoline 5-spd 2-dr model: 65-70hp x 2600lbs. Diesel 5-spd 2-dr model: 55hp x 2600lbs.
Only two choices, so which would you go with? And by the way, none of the aforementioned engine in this post
or my last came with a turbo from the factory or had a kit mad available to it in the after market, unless noted.
Go beyond the "bolt-on".
you will have to have diesel engine to run diesel, cavalier engine will work maby a day on diesel,

Buick diesel? I've never heard of such a thing. The 4.3 diesel is the only other one I know of from that time period and it wouldn't tolerate any funny business. Are you thinking of the 4.1 Caddy V6 which the GN guys love to get?
Olds diesel also had problems with cranks breaking which was never addressed, and cyl head durability was always an issue. Worse yet, Chevrolet was still trying to fix the 700R4 during that time period. The trans was problematic with gas engines but didn't stand a chance on the 5.7 diesel. The poor diesel was blamed for the trans failure more often than not.
I know someone selling a banks kit for a 6.2.

this question is kinda stupid.
the answer is buy a VW.
Working on obtainting an M-Class license... ?? Hint: 2 wheels.
the answer is dont have a heavy foot. dont rev it all the way to redline to shift. and your an auto. just take it easy on it and you wont waste a lot of gas.
