So I tracked down a 1.9td, Guy says he swaped it in from a 95, its got under 190km he wants 1300 for tranny and motor, I offerd him 500 for just the motor, he said timing belt/GP's/waterpump/injectors has been changed. I then asked him how the MPG is, he said GREAAAAT 700-800km a tank...and I'm thinking.. thats low...800km=497miles and his tank is 14.5gal, which is 34mpg....I called him out on it, he said "14.5 gal sounds right…. Yeah…34mpg sounds too low… you’re probably right. The fuel economy is up there though"
My question is, is the mpg really that low for 1.9td? all stock or is there something wrong with it...
-
mine isnt far off from that. if i remember right it was close enough to 46km per L. adn if i did the math right too lol
-
from what i've read the 1.9 td stock.. aren't good at all, compared to the 1.6 for milege in stock form.
But hey.. is 35 mpg really that bad? its better than pretty much 80% of people on the road are getting :P PLUS its got a turbo.. owner probably drives it with his foot to the floor to here it scream the turbo lol
itll improve with some tuning :) i think..? lol
-
well I mean, mines pretty quick, faster then tdi's thats forsure, and i get anywhere from 40-45 with my foot through the floor...I'm not going to dish out money for a motor that gets worse mpg, although I was going to put all my stuff from the 1.6 on it, Ive heard there monsters...but 34mpg...damn might as well drive a gasser....alot less *** to worry about lol
-
is this winter driving? City? I get over 40 regularly with mine. However the cold weather hampers that and I'm currently seeing roughly 750 km per tank. Keep in mind I don't regularly drive my car until it sputters and dies (and I'm sure most of you do the same :) ) so you're bound to be using a few litres less than the entire capacity of the tank.
Its not hard to get 46mpg on the hiway in the summer though.
-
he said summer o6, he said he went to ssmarie from here, which is 430miles, and he said another 30 miles into the states before he needed fuel, so 460miles total. I checkd and it was 34mpg excaulty what he said 700-800km a tank...which is horrible, I just figured the motor is tired
-
it could be that the engine is so restricted that its not that effcient.
i mean gtd 1.6td 70hp
1.9td 75hp.....
just a thought, but if you were allow the proper injection and turbo set-up SHOULD come with a 1.9, it would give better milage......
-
if you want mileage that is similar or better than a 1.6TD, then you need to get a TDI box.
it's all in the driving style. the 1.9 is a torque monster! after putting that into my mk2, i can drive in 5th gear, and still accelerate uphill without the turbo being fully spooled. of course i have an mTDI... if you drive it like you stole it, you'll drink more fuel.
most 1.9 boxes are like 1.6 boxes... the gearing isn't right.
-
I'm not a mileage nazi or anything, Its just I'm not sure worth it is getting the 1.9. I mean i have fun with my little 1.6 boostin beyond 30psi. I think thats what I'm going to end up doing, a tdi-m...always wanted one...got any hints or help in what to look for with the 1.9? other then lookin if the crank was replaced
-

whoa :shock: math must be a bit off :P that's like 2300km per tank
getting back to your story lildevil,
my 1.9 has a T3, 1.6 pin and uped fuel screw, gets hammered on every day through windy up and down mountain roads and I regularly get 40 mpg or 5.90 km per liter. also you are a bit off on tank size, its a 13.5 US gallon tank ( 50 liters )
if I am only hwy driving and keep it under 120 km/h I can get as much as 45 mpg but that's no fun :evil:
and jtanguay is right about the gearing beeing wrong on these trany's... at 120 km/h the tach is at 3000 RPM :cry:
-
my aaz is 39mpg city 49mpg hiway i have the sheet to prove it! thats est. i'm hitting around 45mpg city at -20 to -30C....
-
I can get 600 miles from a tank, nudging 60 mpg on a run and over 50mpg in daily use.
It's a standard 120K non-eco AAZ in a mk3 estate. :D

Is that in the Thunder Bay near Deluth MN. ? The shores of Lake Superior ? WOW, good for the coldness you have.

well the early 1Z/AHU (i have the 1Z) already has the crank fix, but mine wasn't a tight fit with the crank gear. extra material had to be welded and filed, but luckily it wasn't too bad.
i have a K24 on it right now, and it makes good power. to give you an idea, it will accelerate in 5th gear @ 50km/h up a decent sized hill. now thats with a 1.6TD box though... (my clutch isn't holding all the power at the moment... i might need a stronger pressure plate)
i got mine from someone who imported motors from Europe. it was in very good shape. even with just over 100,000km the clearances were still within spec, much in part due to the high quality oils they use. so i had it re-ringed with total seal, and new bottom end bearings with a crank polish.
i highly suggest a TDI box though... the car would accelerate happily with nice tall gears. even if you decide to go with a 1.9TD.

i dont wana throw this whole topic off but what is a "box"? it was mentioned as a 1.6 box and a 1.9tdi box. is this the computer?
-
they mean gearbox

yea as stated its the gearbox. the TDI box has a taller ring & pinion gear which really helps... AFAIK the 1.6TD & 1.9TD have roughly the same ring & pinion (i think there are two different ones only), and roughly the same ratio's.
pretty lame in my opinion... the 1.9 with the smaller turbo will easily push a taller gearbox and achieve better economy than a 1.6.

I'm sure they mean {Gearbox} just a slang word for transmission :)
-
So what your saying is, the TDI box(all years?) will bolt up to a 1.6 and 1.9? plug and play? just mess with the reverse light wiring

wouldn't that be the "***" eh?
-
so I'm guessing thats a big fat no? Cause I just watched a 1z video...and dude was goin 140kph in fifth at 3grand :(
-
it will bolt right up, but the shafts are different, and its cable shift.
you can swap over the rod shift junk into the TDI box though... converts it over to rod. but if you can get cable, its a good swap (its not as stickey)
the rod conversion takes the rod shift part out of your mk2 trans and installs it into the TDI trans.
as for the axles, the TDI ones are 100mm whereas your mk2 are 90mm. a solution might be to find 100mm mk2 shafts, but i think the length still might be off.
probably the best solution would be to swap the 90mm flanges over to the TDI box. i've swapped 90mm flanges into a 1.9TD box with success. now i didn't actually test it, but it worked. it just requires lots of patience, and a nice big c clamp (they are under tension). don't forget to buy the snap ring, and oil seal for it as well. the 90mm flanges will give the same protrusion as your old box, so you don't need to mess around. since your not putting out TDI power, then you don't need to worry about the 'weaker' :roll: 90mm stuff. maybe even install a shim kit while your at it??? :wink:
now... AFAIK your mechanical speedo will bolt right in as well, and you could sell the electronic speedo to someone on this board (hint hint)
a good used TDI box should go for about $500. if you do the el cheapo way of installing it as stated above, it shouldn't hurt the wallet too much. just keep in mind that you should clean the outside of the transmission as best as you can, to minimize any dirt getting in. plan on changing the transmission oil at this time as well.
oh and i almost forgot... you need a 228mm clutch... at that point i would just say f*** it and buy a prothe clutch, or a used one with flywheel. theres more than enough clamping power for your 1.6, and i doubt you would ever slip that thing!
edit: for an extra oh say... $900 you can also get the taller ring & pinion gear + taller 5th gear to make your car roll 140kph @ 2000 rpm or so? :lol: ah the joys of TDI boxes...
