Turbo Diesel 100series "Low Torque"

Hi all,

Firstly I would like to introduce myself. My name is Geoff, I own a 05 TD "manual" 100series fitted out mainly with ARB extra's. I've just moved back from Borneo Indonesia after working over there for the past 6 years (hense the user name). Currently planning for a trip to the cape in May.

Now to my question, I purchased a TD 100 series mid last year & have only managed to get 8000k's on the clock until now, the cruiser has been great, but I have only recently noticed that the vehicle has a severe lack of torque. On a steep hill (car empty except driver) I find the only way to get going is to rev the engine up to around 2000rpm & ride the clutch until I have enough momentum to enable the engine to pull away with 2000+ rpm. I have to ride the clutch that much that you can smell the burning clutch material everytime I get stuck on the hills. If I try to let the clutch out any sooner or with the engine down around the 1000rpm the engine looses revs & dies. I have found the only way to get up the steep incline going to my childrens school is to put the car in low range, which I found outrageous. Can anyone else out there with a TD manual 100series give me some light on this issue. Is this a product problem or have I purchased a lemon?
Cheers,
Geoff.

Take it back to the dealer and let him fix it. If you try, you could lose your warranty.
It should not need to ride the clutch to 2000 revs to get mobile.

There is something seriously wrong with your car. Turbo lag is evident even in my auto, which are a far better proposition in a turbo diesel, but certainly not to that extent. Your car sounds like a 2.8lt Patrol which is the worst off boost vehicle I have driven. A normally aspirated 4.2 would be stonger below 1500 revs. Possibly you are in limp home mode or a vacuum pipe off for such poor performance. Cheers Rob

Currently going through the local Toyota dealer, Toyota's first comments were "yes" this is a big issue, but this has changed over the last 2 month until today when the service manager tried to advise me that "this is normal operation". I asked who was going to pay for all the clutch replacements after warranty. So the saga continues until I find an other TD manual 100series to compare with."Should have gone with the auto".

Cheers,
Geoff.

Turbo diesels and autos are a match made in heaven. The torque converter compensates for any turbo lag. Drive an auto and be amazed at the difference in driveability. Cheers Rob

Just came back from Tassie. Worked at Mount Stuart Primary School. Mate, they have some hills there. My old bus with it's new 1hz motor with after market turbo.... took off up the hills without much problem. It weighs 3 tonnes unloaded... but was loaded! I think you have a problem! Maybe the dealer needs to get in and have a drive!

Wild Man,

The symptoms you describe are outrageous for a 100 series turbo diesel Cruiser. I've just had one stolen but when I WAS driving it, that truck was a veritable thorougbred racehorse. It was a Ferrari of a 4WD. Up to about 1800 RPM it was eminently driveable, pulled OK and was flexible with little or no turbo lag. After that it was a missile!! It simply took off! The pulling power and torque were unbeleivable for a vehicle that tips the scale at 2.5 tonnes. I used to pull a 19 foot caravan weighing 2.8 tonnes at 110 khm and pull out to overtake a 3 trailer road train at 130 kmh without a grain of concern. (Yeah - I know it'a naughty, but the road was up near Carnaravon - dead straight, see fer miles!). I never had a problem going slow, off road, uphill with it either.

Tell that Toyota Service Manager that he's a tosser.

Or gimme his number and I'll ring him.

But first, tell me - how steep is that hill??

Geoff,

Drive a 79 series ute, for work, that only lacks the intercooler of the 100series. It pulls like a train, even from idle.

Been a bit wet here recently, and have been caught in some heavy silt at times, but a big squirt on loud pedal has saved the day.

Sounds like you have a fuel problem, or the 'puter is on strike. No hill in suburbia should need low range, not if it's near a school!

Where'd you buy the 100? In Borneo?

Hooroo...

Bob,

Thanks for your input. I had a TD 79 series troopy over in Indo & as you said, went very well. That's why I can understand how Toyota can get it so wrong with the TD 100series manual. Purchased the vehicle in OZ. I think Thommo has got the fix with the Dtronics " It's a shame Toyota cant fix there own issues".

Good Morning Geoff,

I have a TD 100 manual first of the new 2003 models brought out and have suffered the exact lack of low down torque you are suffering in high range except mine was higher than 2000 rpm.

It would not pull skin of a custard let alone my boat up a concrete launching ramp in high at all. Stalls going up hills as per yours etc etc.

After months of frustration and regret from getting rid of the manual 80 series, still kicking myself, I finally went and purchased a Dtronics chip, Intercooler and exhaust which solved the problem to a large degree but however still did not pull like the 80 series uphills, boat ramps etc, but on the flat went like a rocket.

Only got a month to go and the 100 series is getting sold of and replaced by the H2.

Not much help I know but good luck

Regards Thommo

Thanks everyone for the replies on my saga.

Bilbo / Thommo,

Any chance of having a chat with you guys over the phone regarding the low torque issue? My e-mail is gboyle3@bigpond.com

Cheers,
Geoff.

Geoff,
I've got a 78 Series Troopy, same engine but no intercooler.
Basically I let out the clutch then think about what comes next. It'll pull from idle no problems.

Sounds to me like there is something not quite right.

One thing that I found with my 2000 100 series TD was that 1st gear was low. So low in fact that often I didn't use it. When I did use it I was into 2nd gear in an instant, so fast was the torque delivered.

There's a serious problem with Geoff's truck.

"Roachie" - I'm still waiting. It was due to be finished on Wednesday and Brunswicks are still wiring it up today. Should be here tomorrow. It's a bit like a kid finding out that Christmas Day keeps going back a day and Santa just WON'T turn up!! 'Kin reindeers -I hate 'em ;)

This sounds wrong to me, but if you have only done 8000km's then the car will be under warranty. On the other hand I find it hard to believe a new TD like yours would have anything wrong with it, they are virtually bullet proof. Have you put bigger wheels on it..?

Currently running 285/70/R17. Toyota tried a set of standards while doing there checks & said the difference was hardly noticeable.

Thanks for the replies. I'll keep you posted on the out come. Is there a fair trade dept that I would be able to refer to on an issue of this matter? Priced the Dtronics & 3" exhaust today. I was told that this would increase the "power" & "torque" by 25% to 30%. I hope Toyota can sort the problem & save me the $2750 on more upgrades.

Cheers,
Geoff.
