    Ouch! I just priced both an M Class and R Class and the M Class starts at $40K and the R Class at $48K... Don't think I can afford that or just the engine itself. Why are they so expensive? I think a VW TDI is the best route for you to be honest, since they're quite modern, easy to find, and are really reliable. I'm still looking for an iMark 1.8L diesel though since I'm not sure if a TDI can be easily adapted to RWD and lateral mounting.
    edit: The following question was in reference to the Isuzu diesels, not the VW ones, I know they're reliable. Does anybody know if they're reliable or economical though (the Isuzu ones) and what MPGs can be expected in them?

    Couple links for you, for the VW diesel. Lots of options out there from the basic Samurai tranny to using a Toyota one as well:
    http://www.rocky-road.com/diesel.html
    http://www.acmeadapters.com/index.php

    Isuzu Diesels are pretty easy to find, just look in any refer trailer and odds are that's what's running the cooling compressor. Tranny's are a bit harder to find, not a lot of those diesel Chevettes, I-marks, or '84 diesel S-10's around. One of our European or Asian friends should be able to get you a tranny without too much fuss, though. The Trooper was available here with a diesel v-6 as well, and from information I've dug up I'd say it's 75% or so it uses the Northstar/Catera/Isuzu bell housing bolt pattern, which would make the tranny search much easier.
    Lots of Opels, for a long time.

    Sorry to bring this back up again, but I came across a VW Rabbit in the papers over here the other day for $800. Supposed to run and everything. Its a diesel of course, so how do you all think it would work in an Ascona? I'm not sure about its power or anything, but know its supposed to be extremely fuel efficient. (Comparable to the TDIs.) Also, if it won't work in an Ascona, what about just taking the entire Rabbit and fixing it up? Ideas? its supposed to be in good shape. Any ideas on how much to get the engine itself running and reliable? MB might not appreciate me being late for a car breaking down...

    i dont think you can put VW and a question about reliablity in the same post ?? can you ,they seam to go forever

    it still has the same problems though
    fitting a transverse fwd engine into an inline rwd body means you have to find a gear box that will bolt to it and there are none in the Volkswagen Audi Group
    untill you get up to the bentleys and you can run an ascona for the rest of your life on what they would cost

    wasn't there a time when some of the VW diesels were laterally mounted? I have a friend that changed the crank in his and used an adapter to mount a Rabbit diesel to his Suzuki Samurai (I think using the stock Samurai transmission).

    Economy!

    "Economy" = NOT spending money!
    Putting any sort of diesel into a GT will cost far more than getting a running CIH opel 1.9L motor and plugging it in without having to do any modifications.
    Use the money saved to buy gas - and be driving your Opel a couple of years sooner!

    I would agree if you're talking about buying and running dino-diesel. But IF you factor in that in the US you can make biodiesel for about 70 cents per gallon versus the current price of about $3.09 per gallon (in Western PA at least), AND the fact that the car could approach 50+mpg, the curves cross over much sooner. Granted, that's a big IF. As mentioned before, there are also ways to get a diesel engine up and going on FREE waste oil for those so inclined (I have a friend with a diesel jetta that runs on waste veggie oil from restaurants). I don't think it'd take all that long to recover the costs of just the used diesel motor, the adapter, and the transmission for a swap into an Opel, but I'll likely never do it because I dont' have the skills or time required to make it cost-effective. If one were to have to pay someone to do the fabrication for the swap, then it's all tossed out the window.

    For some folks on here with excellent fabrication skills however, I think this would be a very nice swap. Not only could it be a cool car to show off one's skills, it would be very efficient, green-conscious, and not all that heavy on the pocketbook. Come on, someone tell me a Sportwagon with a VW diesel wouldn't be utilitarian enough for you?

    If I ever were to try my hand at building a diesel vehicle, I think I'd try a Jeep and import one of the International HS2.8TGV engines. The same Acme Adapters folks have a reasonably priced adapter to tie to the common GM trannys, and there are even pre-fab'd motor mounts, etc. for such swaps. No electronic stuff to have to hack together either. Fairly pricey, but still less than buying a new Jeep - and it'd last forever.

    all are laterally mounted (transverse ,side to side) after the air cooled engines ,only the audi has an inline engine but has fwd so the box is no good for us. the problem is getting a box to fit for inline use (as our opels are with the crank inline with the centre line of the car )
    the idea of an adapter plate and another make of gear box is what i was saying when i said " it still has the same problems though
    fitting a transverse fwd engine into an inline rwd body means you have to find a gear box that will bolt to it and there are none in the Volkswagen Audi Group
    untill you get up to the bentleys and you can run an ascona for the rest of your life on what they would cost "

    jim i can pick up running rabbit diesels or opel diesels with rwd for $100 US so with the $60 i would get back from scraping the shell how would $40 not come under economy even when you add the cost of new fuel lines and fabing mounts i can do a change over for $50 granted it may cost more in the states to do it and with diesel 1/2 to 2/3rds the cost of here it will take longer to recoupe but not that much longer

    A customer just came in today with an old willys jeep. He swaped in a diesel from a toyota, a 25L motor I believe he said. Intake was on the driver side but the exhaust was on the passanger side. It also was not very tall so it looked like it might fit in an Opel.

    1971 opel GT diesel engine swap out

    Hi I am new here. I have been scouring the internet for any info on what would be the best diesel engine to swap into my 1971 GT. I have redone almost everything in and on the car. The engine is going and I would love to go diesel with it. Any one have any info? :banghead:

    The TDI Turbo Direct Injection engines of new,.... that would be a good choice.

    But the older I-Mark / Isuzu diesel engines or the older VW diesels, no way.

    Diesels trucks are definitely great. My 7.3L Power Stoke in my Super-Duty F250, 5 stick shift speed 4x4 and gets 18 mpg towing 7000 pounds of trailer and Opel at 70 to 75 mph.

    vw engines

    Hello;

    I just saw the topic and I am able to provide some info.

    The vw Passat, the early models have longitudinal engines, but they are still front wheel drive. They are the same generation with Golf 2 or Golf 3, the ones I assume are known in US as Rabbit ('80's generations).

    If you want economy, why not use etilic alcohol or LPG on the gasoline engine? Both allow higher compression, as they are greater octane-graded than gasoline (LPG: 105 - 110 octane rated).

    Also the 80's Opel Astra's have some engines: C20NE (85 kW) or C20XE (DOHC 16V, 110 kW), 2 liter both, transversal mounted, about which I heard (not verified) that they bolt on the gerbox with no problem; you have to manufacture one bracket and the exhaust...

    VAG group - volkswagen+audi - are, in most cases (except the old Beetle - rwd with the engine on the back) either front wheel drive, either all wheel drive. Rwd you can find on VW Camper, if I remember well...

    Manta A 1.9 TDi

    Wow.....has it really been 3 years since I posted this topic? Time sure has flown by and work has gotten in the way. It was not all wasted tho - I spent the last 3 years making biodiesel and running it in my Nissan 4x4 DTi and learnt a lot / had a great time. But the Nissan is now going and I have room for my new project. The biodiesel has worked fine (but not without its problems) and although the fuel drying (homebrew) is still hit or miss at times, I can now get a good mix w/ dino and lean out until I get the optimum blend. I just don't like 4x4s that much and prefer lighter cars.

    I like classic cars, but there are very few classic diesels apart from MBs (and the very respectable power you can pull out of those if you spend the time), but they don't do it for me and I figured I should go ahead and make what I want. I always liked the pretty little 70-75 Manta As ever since I was a kid and have 90s~ Opel / Vauxhall 1.9 TDi to adapt into a 70~75 Manta A. My brother used to own a dark metallic green 1.6S in the early 80s and have fond memories of an enjoyable Xmas Eve in 1983 (damn, was it that long ago)doing donuts in the shopping center car park. I like the size / shape / balance of the Manta A and I am looking for a vehicle to push biodiesel / alternate fuel that is not the same lame collection of VW Rabbit / Jetta / Volvo etc. (apologies to the above fans), but a 'crossover' car that combines both beauty and practicality. I also like the diesel torque these modern mini diesels offer.

    The last 3 years have pretty much consolidated the fact that a certain amount of $ need to be spent and fabrication completed, but nothing that is not doable. Like any project, you address it in small stages, do what you can yourself / learn and delegate / pay for the stuff you cannot.

    I hope to find a suitable Manta A through this forum while I find the half-cut Opel Vectra etc. 1.9 (loom / goodies etc. elsewhere). Most importantly, I have my better half's blessing to go ahead and make it all work.

    Hopefully will be able to start the ball rolling in 2008 as time allows and parts are collected.

    Rather than start a new thread, I thought I'd resurrect an old one. New diesels are starting to appear here and there - anyone running one of the Bluetec diesels yet? I recently read where Honda just completed construction of a new plant to build their diesel engines for Accords, Civics, and CR-Vs, but there are still no plans to offer them in the US, despite the fact that they'd offer nearly 50mpg and nice torque compared to the gas versions.
    For my long commute, I'm now driving a '92 Mercedes 300D. Diesel is only $2.25 a gallon (similar to premium), and I'm getting between 35 and 40MPG on the highway - that's hard to beat. There are good things happening on the fuel front as well with things like this:
    http://www.newscientist.com/article/dn17066-plastic-cups-could-boost-auto-performance-.html. Who knows if it will work out long term, but it's still interesting. A few years ago I took a class on Biodiesel, but I haven't fooled with it much because I don't want to handle Methanol and Lye with an 11yr old around. More recently I've been reading some info on the waste vegetable oil systems like Frybrid, Vegietherm, and others. Any WVO or Biodiesel folks on here?

    In Europe you get the Opel Omega (rwd) with a 2.0 and 2.2 DTi engine, I have a 2.0 wagon and while I wouldn't describe it as a sporty engine, especially in a heavy car like mine, it's fairly compact and unless I'm mistaken it shares external dimensions with the rest of the "ecotec" engines so it would almost be a "bolt in" (yeah right) as long as you get an engine with transmission

    The Omega 2.5 diesel is a 6 cylinder BMW unit though and while interesting from a perfomance pov I doubt it's very practical

I know you can get it with the VR6 and a few more Audis have it. Just a thought
    2 down sides to this
    1: the vw engines are all transverse so wont go in without major body changes
    2: if you pull the front shafts it will not run as the drive trys to go to the missing wheels <img src="https://www.opelgt.com/forums/images/smilies/frown.gif" border="0" alt="" title="Frown" class="inlineimg" />
    you would need something like the european ford system (from a merker /granada ) where you have an inline drive and a take off box to put the drive to a front axel that almost matches the layout of a gt

    That isn't necessarily true vw tdi can be adapted to an inline, it is quite common in jeep swaps
