diesel conversion....
well, hello to everione here.
I wanna put transit diesel in my aero this spring and sell 3.0.
This van will be used like a small truck and for fuel economy I wanna do it. Later it will be easier to sell diesel van here. As donor I wann look for Transit 2.4 ore 2.5 TDI.
May be to put intercooler behind the radiator I will remove A/C. to use it in wintertime I wanna add fuel tank heating with coolant, electrically heatied fuel finters/separators and electrically heated fuel lines. It is Ice age here againe, -25 dgr C and a foot of snow!

Let us know how that goes, we here in the states would be interested, especially if the swap is fairly straightforward. The biggest issue in the Us is that small diesel engines are hard to get, and then you need a trans that can match them.

i am also interested your search for a good diesel swap for our aero's. i think it's messed up that more car's aren't diesel. it makes no sense to purchase a vehicle that gets crummy mpg's (trucks for example) when their diesel counter parts perform the same task much easier and with more mpgs.
aren't the new jetta tdi's supposed to be getting an upwards of 40mpg's? my friend always raves that you can chip/ re tune them to get lots of tq and h/p out of them while maintaining great mpgs.

Cheap engines are in UK JYs. There are conversions workshops here (RHD to LHD) and they use to sheep a lot from England and I wanna ask them to get for me diesel engine. But I do not want to get engine with VP44 fuel pump becouse it is too incomlicated (CAN controlled). CRD engines are better.

The new Jetta TDI gets great gas mileage while being one of the cleanest burning diesels made today. I think that must have been one of the problems with diesels of the past, too much pollution. It didn't help that GM's feeble attempts at building diesel cars in the 70's were such flops. The very word made people think of smoke belching trucks. If all that carbon lost to soot production were instead being directed to generating mechanical energy, the diesel engine would be even more efficient as well as clean burning. I think that's what VW/AUDI may have achieved with their new TDI engines. But any used diesel engine that you want to swap into your van will most likely be the "dirty" type.

Let me disagree that there are no small diesels on US market. Many Russian and Ukrainian van maker use Cummins ISB series motors. This engine with ZF 6st tranny easily fits truck of F150 size. For Aero Perkins 4cyl engine is good.
TDI is a good technology, but there are some hidden traps. For example one leaking injector drops rail pressure and engine stalls. There are some critical components, like two fuel pumps, pressure regulator, one way valves, limiting walves... All this stuff works under very hight pressure - 200-1000 BAR, so one failed component makes engine to stall. So I suggest PLD and MUI are better. Some companies like Cummins and Scania provide HPI (well known on ISX engines in NA), Cat provide HUI, but PLD amd MUI are more reliable. with one PLD pump ore failed injector engine misfires, but runs to nearest workshop, bad actuator on ISX - 3 cyl not working! HUI by Caterpilar is good, but oil controlled ingectors are temperature sensetive, -15 dgr c and we get in trouble....so.... my chois is not so easy.

dang you really know your diesel engines man. what if you had an oil heater? i'm guessing the promblem you face would be getting the engine to crank over if the oil is too cold to create proper oil pressure?

I use Shell rimula oil for diesel engines (good oil for gas. engine), fully syntetic, crancks any weather outdoors.
Yesterday we had -25 dgr C. And snow!!!!! more then enought, Hightways were closed. Today it is about -4 dgr C.

Any progress with your diesel aero?
I'm driving a 1985 MB 300D for the winter, pretty rusty car underneith and PO was afraid of it. I've driven worse
I was thinking about putting the 3.0 5cyl TD engine into an Explorer 2wd but this would be an excellent engine for an Aerostar and I'm going to look at another 3.0 aerosport shorty Monday morning.
I found a spare 3.0 TD engine/trans from a 1979 and its available locally for $200.
this got me thinking, maybe I should stuff the 5cyl into an aerostar instead of a 92 2wd explorer. hmmmm.
those 2.5 TDIs are a pretty cool motor, not available here in N/A but friends from Brazil love them

Well, about 5cyl engine I wanna warn you about some problems you will get. First of all, purchase engine with tranny. get mercedes/dodge sprinter DS to make one of two.
Prepare for oil pan welding/cutting. For aero... You are to make air intake a bit lower... cutting and argon welding. You will make new engine mounts on x-member to fit engine with mercedes mountings.
Find any dodge sprinter and look under hood to know how to do.

I have a 1.9tdi from a 98 jetta and will remove the electronic Bosch VE injection pump and will go with a non electronic unit. These engines are compact and give good mileage. The engine has ac and psteering. Parts are not too expensive either.

1.9 - weak solution, first of all what tranny will you use with this engine? my friend tried to use ford 2.0 turbo... van accelerates with pedal to floor.

Hi Pablo. From vw tdi forums these engines can put out the same hp and torque as a 4.0 with little modifications. There is a guy who put the whole setup into a Dodge Caravan!!! If I stay with the ecu and pump it can be chipped for increased fueling and timing. I am using a zf 4hp22 trans mission. This trans has a replaceable bell housing and is installed behind a lot of rwd cars giving a lot of choices.
