Has anybody attempted to swap a 6.5 into a fiero. Does anybody know the dimensions of said engine. a buddy of my at school has one for sale pretty cheap. would be a fun swap if it is possible
Heh...I don't want to discourage you, but it will be more trouble than it's worth. You would most likely have bragging rights for most displacement in a Fiero, though.

You would add a lot of weight to the Fiero, the 6.5 has got to weigh 500 lbs all by itself. I have a 6.2 diesel and it was all my hoist could do to lift it. Also finding a trans to work with a diesel they only rev to about 3500 rpm.

Alright...WHY do you want to do this? If you're wanting big HP somethign that makes 2/3 the power but revs much higher may be quicker. I know I would go CRAZY if I had to shift at 3.5k, no matter how powerful the engine was. That would be VERY short intervals even on my 200whp engine, and on a diesel it would be just horrible. You would basically have to use a 6spd or somethign and only use gears 3, 4, 6, and 6. Maybe not even 3.
Once again not trying to rip on you because it sounds awesome, I just think it's a bad idea with all the "better" options out there.

I'd have to agree with penguin here. I'd love to see a diesel in a Fiero. Personally I've pondered the idea of a VW 6 cylinder diesel or even the V10 diesel both from the taureg. I think either would be good and definitely unique. Plus there's beneficial trade offs going from a gas to a diesel engine. Diesels make less hp but can make at least twice that in torque. And torque is whats needed to get off the line quick. For example, my dads '03 Jetta TDI makes 90 hp and close to 180 ft-lbs of torque. The jetta is quicker off the line and thru second than my buddy's turbocharged Sentra SPEC-V that can run mid to low 11's. Don't know if that's what he looking for or if he just wants to do something different, but I'd say go for it.
Also even though the engine may only rev to 3500 i believe the gear ratios in the trans could be bigger than in a gas engine trans due to the greater torque, which would cause you to be in gear for a comparable amount of time. Cuz i know on my dad's jetta it only revs to 4000-4500 max and it seems like it's in gear for a normal amount of time. Don't quote me on this cuz it's just a theory as to why its in gear a normal amount of time, but i know he wouldnt have to shift every other second.
Just my 2 cents.

If you manage to install a VW or Audi 2.7 or 3.0 Turbo Diesel engine with chip tuning, you can be sure that you will leave many v8 fiero behind you! These diesel engine are awsome, power full and low diesel consumption (6 to 8 L/100Km!) You drive them like a fuel car (max RPM close to 5000!)

This is my plan. however those 3.0 diesels cost around 6,000 here. Hoping that Euro keeps on dropping.

Lots of good points made on it not being a great idea. Add this one; with our engine being where it is, it's real easy to feel it running behind you. Put a desel there and you may need to hold onto your fillings!
I say go for it, but I would suggest getting a newer engine for the project. The 6.5 is a very good engine, but it is a wider engine than the 5.7 or the 6.2, and is much heavier. If you could overcome the weight and width issues, you should be good. Also remember that the 6.5 has a deep oil pan, so there would be fabrication there as well. If I was you, I would almost look into a Duramax. It is a 6.6, a little more compact than the 6.5, and much more fuel efficient, along with being more tunable. Go to some of the diesel forums and read up what people are doing with them. Their are some very quick diesels out there that are putting high HP gas engines to shame. Just do your research, plan ahead, and go for it. I realize they naysayers have some valid points, but with enough inginuity you can accomplish anything you set your mind too.
The transmission issue would no longer be an issue if you could find a transmission that has very, very long gearing. Even a 3.32 may not be long enough for a big diesel, and you can bet it will split in half pretty quickly. Basically...you're going to have to find a transmission outside of the Fiero world. Other than that and finding a clutch that will fit it, it's just cutting, fabricating, welding, and nuts and bolts. The transmission is the only huge problem I see being that you want a manual if I remember right.
Darth Fiero (Sinister Performance) is in your city, so count yourself lucky. He can probably help with many of your problems. If you ever accomplish this I'm sure I'd be willing to drive an hour from Muncie to see it.

If you want diesel at any price, snag one of VW's new Twin Cam 2.0 TDI engines and matched transmission. Not sure if they're available with a traditional stick anymore, or just the DSG.

right now i am in the early planning stages, i would like to have a standard but an auto would be ok, ive been contemplating a CVT tranny bu im not sure how easily they would be to get a hold of. Mostly i want a diesel that has good power, doesn't have to be mind-blowing, and get better than 20 mpg. i chose 20 because that's what i am currently getting in my duke

If you're Duke is only giving you 20 mpg, there's something seriously wrong. Fix that problem. Don't fantasize about a ridiculous engine swap because your current engine needs a tune up.

I don't like diesel ( anyone his likes and dislikes ) but if I had to put one in a Fiero , I 'd go for the v6 4.3 Olds , too . Not very powerfull but lighter . Plus you 'll have a free massage at each trafficlights ;-)
I believe most of GM's diesels have the SBC bellhousing pattern, so maybe a 4T65e-HD would bolt up? With the different chain and final drive ratios available on the 4T65, you ought to be able to make a good ratio and then adjust the shift pattern on the controller for the diesel.
Sorry, I don't think you'd get the award for the largest displacement. Didn't someone do a Cadillac 500? 500cid = 8.2L. But, who cares, a diesel Fiero would be awesome.

I know my duke has a problem, Its got bad rings. and in order to fix it i have to drop the engine anyways, so i figure might as well swap the engine while im at it

And, it would fairly easily fit into a fiero as well, when it is released. The engine is the same size as a Small-block, but it cranks out some 300HP, and over 520ft/lbs! Plus, it weighs half as much as the afore-mentioned turbo-diesel, as it's made of compressed graphite instead of steel.
The only thing is, when are they gonna start selling the bloody thing >_>

Dukes are cheap. Replace the duke, then think about a real engine swap.
im going to school for high performance / diesel mechanics at the university of northwestern ohio. and im turning my fiero into my project car while im there, im not planning on doing the whole swap in one weekend

toyota has a composite graphite iron diesel engine in some of their vehicles.... i think the landcruiser has it... they weigh less than most diesel engines. i would go with that.
ford and gm havent released it yet from what I understand. the range rover in australia and britain have a 3.6 v8 diesel. its composite graphite iron too. i would love to have that.

The Mercedes-built 3.0-liter CRD produces 218 hp (160 kw) of power at 3,800 rpm and 510 Nm of torque at 2,000 rpm�33% more power and 28% more torque than its 2.8-liter predecessor previously offered in Europe.

I had thought about using that engine, it also comes in dodge sprinters. I decided against it due to the fact that I would have to buy a transmission adapter for the Mercedes vs with the VW 3.0 their transaxles bolt right up to it.
Comparing those engines from both articles, . . . they look like the same thing. Just different displacement. 72° V, variable pietzo injectors, exhaust out the top, variable vane turbos, I see more alike than not.
Except that one is a 3.0 Mercedes 6 cylinder currently in production to be used by Chrysler and one is a 4.3 vaporware 8 cylinder touted by a still-failing General Motors.

I think a smaller diesel would be a better fit for our little FIeros. Once I'm out of college I plan on installing (or having installed) a VW 4 cylinder TDI with matching manual trans (yes the new ones still come with a 6spd manual). They have been around for years so shouldn't be too hard to find but won't be cheap. It shouldn't be more complicated then BMWGuru's VR6 swap.
Those who mentioned the 3.0 V6 TDI, remember that engine was just released in the states so you're going to pay an arm and a leg for one!
