Good point on the dollar.

I want to hear more about how your projects are going. Any writeups or pictures? Are you driving them yet?

Another possibility is to look for a Komatsu 4D95 engine which is the same as a Cummins 3.3.

The Cummins is made in Japan and today the dollar is down against the Yen at its lowest since 1995. Prices on the engines are not going to get cheaper anytime soon. I am sure the dealers are going to raise prices. Fuel costs are also causing shipping costs to rise.

Al's Diesels Only on Ebay has some great prices and he doesn't require a core charge as some other sellers. His current Cummins is new and not rebuilt.

I suggest you be patient and look on Ebay. The economy is tanking and people usually sell toys when they need the cash. I bought my Cummins new last year for $2300.00. It had some minor damage and the seller needed the money. I had to buy a longer flywheel housing that put me at $2700.00 total. I also bought a new Daihatsu 3 cylinder last year for $2000.00 for my Geo Metro project. The engine was a test engine that the company gave to him via a raffle. The seller works for a commercial lawn tractor company.

Just an update. I finally got my turbo back from the rebuilder and it works much better know. The turbo was definately damaged when I got the engine. The exhaust and compressor housings were knocked out of line slightly. No more annoying whine at no or low boost. Also filled up with fuel with timing advanced 1/8" and bad turbo got 34.6mpg so was pretty happy about that. Will see if it gets any better with properly working turbo.
When the turbo was bad I could only build 12~13 psi of boost (no wastegate).
After the turbo was repaired I can get 21~22 psi. Looks like it is time for an intercooler.
Also from some of your questions above I used the shallow engine side bellhousing adapter. It just takes a different flywheel adapter from phoenix castings which was more expensive but cheaper than buying the different housing from cummins.
I chose the nv3500 because it was the stock trans that came in the s-10(4.3 v-6 only). And did not require any other special bellhousings or adapters. NV3500 has integral bellhousing cannot be changed.

Nice!

I'm assuming since you're building 20+ psi of boost that your wastegate is not hooked up? Are you worried about damaging the turbo with it making that type of boost?

So you went from 31 to 34.6 mpg with your timing advance. That's more than the 10% I was seeing with the slightly less advance that what you're using. I may have to follow your lead on this and advance mine a little more . . .

Bell Housing

Help me out. What would be the prefered set up? The SAE 3, or SAE 4? and what depth flywheel housing would cause the least amount of adapters?

Thanks, I think you guys are doin a great job. I hope to get going on my swap this summer.

The best advice I have for you on SAE 3 or 4 is call Phoenix Adapters (PA). Bill is the Guru Jim is also very knowledgeable.

If you go with the SAE 4, I like my setup (shallow SAE 4 with 1.12 spacer) this route saves 50+ lbs off the engine and 15.4 lbs off the flywheel. (If were still discussing the 3.3 Cummins)

The guys at PA have a 1.25 Spacer in stock therefore cheaper (215.00) but you have to have it machined. To have a custom cut to 1.12 their quote was over 400.

How much did that cost

Just curious what your mpg's were like with that same commute on your gas engine.

I only ran one tank of gas through the truck with the gas engine in it and it got about 22mpg. I filled up this morning (first fillup after turbo repair ) and got 34mpg. To your question earlier yes I have the wastegate unhooked at the moment. When the turbo was repaired the company put a wastegate on that was supposed to be good for 12-13lbs of boost but on the first drive it would only build 8-9lbs of boost which made full throttle acceleration sluggish. So with the wastegate unhooked I try to limit the boost to about 15lbs with my right foot.
As for the other question about adapters the shorter flywheel adapter was about $160 more. For me going to the longer engine side bellhousing was not an option as it was going to make a lot more work to get the whole package to fit in the truck.

So it looks like you've gained >55% improvement in fuel efficiency on winter blended fuel. That's good stuff. Now if only diesel prices come down closer to RUG . . .

please explain to me how a komatsu 4d95 is the same as a cummins 3.3. i'm not trying to be smart. i dont know anything about komatsu. just curious how the komatsu is the same as a cummins. does komatsu make the cummins? is the komatsu identical? if it is, that is very useful info. or do you mean that the komatsu is similar in size, weight, dimensions, and horse power? it would be great if you could tell us some specifics.

p.s. if anyone knows of diesel engines "similar" to the cummins 3.3 in size, weight, dimensions, and hp please post them. i would really like to find an engine that has been out long enough to have accumulated in rebuild shops. every penny i can save on this project i can spend on the next one.

This probably explains it a little better...
http://findarticles.com/p/articles/m...66/ai_69493996

You could always use a VW TDI motor, a toyota diesel, isuzu diesel, etc...

Maybe we should start a new thread titled "Possible diesel engine choices or engine specs..."

Anyone that has info on any available engine can post it there for everyones use.

thats a great idea. i think this conversation has definitely strayed from TDI's conversion. if you start one put a link to it in this thread.

as for vw, toyota, isuzu, etc...... the data would be interesting to me but im looking for a brand of engine that is serviced in my area. i live in a rural farming area quite a ways from any metro area. to get good service (advice and locally available parts) i need to stick with cummins, cat, john deere, or kubota. i have friends that work at all of these dealerships and they have been sent to school to repair these engines. ive looked on the company websites and the only one with an engine that fits the bill is the cummins b3.3. (havent found any data for kubota yet) cat and deere offer engines comparable to the 3.9. the problem is that those engines weigh 750 to 900 lbs. (b3.3 weighs about 550) the problem with the b3.3 is it is very rare to find a used one. i realize that in the end there is a 90% chance that im going to shell out the cash for a new 3.3. im just trying to rule out other possibilities first.

thanks for the links TDI. i emailed the seller of the one on ebay that didnt sell but they havent responded yet. how did you find those engines on ebay? i searched several times and didnt come up with anything. i tried several different search terms, even just "cummins" and never found a 3.3.

i checked out the link posted for komatsu/cummins. it said that they had an agreement with large high HP engines (1900 HP+) for komatsu's mining division. there might be small cummins engines in komatsu equipment, it doesnt say.

I see what you're saying. A VW motor might work, but I guess that depends on how knowledgeable the VW guys in your area are.

I just thought of something else. What about a Deutz motor? Bobcat uses some pretty high power motors in their more modern machines, but pricing might be a major limiting factor. Also, first thing we'd need to do is see a chart for the engine you'd be considering and look at the power band.

If the power band isn't practical, can the motor be tweaked to be practical?

Just something to consider...

Does this link work?
http://www.deutzamericas.com/webgate...AL-6HPJDX-EN-p

Looks like deutz makes some autmotive engines...
