I'm looking for a new truck as some of you would be aware. I'm considering various options. One is an
old truck and transplant a Chevy V8 disel in it. The other is a new Toyota Troopy.
I've had a look at some 2002 and 2003 model Toyota Troopys and they seem to have the HZ diesel motor in 'em. No turbo as standard. And fair bit noisier than the GXL HDT motor. I do long distances and I've had enough of noise with my Ford Maverick ute.
I'm given to understand that the current TURBO diesels in Troopys have the same motor as the GXL Turbo Diesel - the HDT. First question - is that assumption correct?
Given that is correct, why is the power and torque lower in the Troopy engine than it is in the GXL Turbo Diesel? I've been told that's because the Troopy turbo diesel doesn't have an intercooler. Is that also correct?
Assuming that is also correct - why doesn't it have an intercooler?
After talking with my son's mate that specialises in performace cars and coupling that with what little I remember from my early days a diesel mechanic, I reckon I can get the same power as a GXL TD by fitting an intercooler. i.e power & torque up by about 15%.
That would be nice Troopy.
It's no good asking Toyota. They just wanna sell me one. The salesman just look at me with glazed looks. Ya can see thier little brains asking 'What's he on about?" 'What's an intercooler?" "My head hurts".
My rig, with caravan, would then be able to pass road trains like an arseshot greyhound as did my lost lamented GXL turbo diesel did, oh so long ago - about 5 days ago actually!
Wonder where it is? The Barstewards!!!
They'll be arseshot if I catch 'em!!

Bilbo,
Both the troopie and GXL have the 4 valve 1HD-FTE motor, with GXL having the intercooler.
A cheaper way to bring the troopie up to GXL specs, is to put a Safari engine management chip in it, about $1450. Think the intercoolers run up over 2 grand, and there is no extra plumbing with the chip.
Only been in a few troopies, but think you'll find them a bit noisier than the GXL.
2nd hand troopies, and utes, with the factory turbo, are as rare as rocking horse poo, and expensive. Feel there could be an increase in numbers of these vehicles in the future, because many of government depts are buying them. eg national parks, railways etc.
2002 turbo utes are $29,100-$33,600, on Redbook at moment. Troopies would be a bit dearer.
No word on the GXL?
Hooroo...

Hello Bilbo,
As I responded in your earlier post, I have an RV Troop Carrier on order, in fact the salesman told me yesterday morning he would have it yesterday and would ring. (Think I'll need to arseshoot the salesman, haven't heard from him yet)
To get the factory 4 valve 1HD-FTE Turbo Diesel motor you need to
check out the RV Model Troopy. They come in 5 and 11 seater. I've ordered the 5 seater.
Troopy's don't have the intercooler. Official word from Toyota is the GXL intercooler won't fit behind a Troopy grill.
To me the lack of an intercooler to get a live front axle and turbo diesel was
well worth the compromise.
Davoe pointed out in an earlier post the Troopy and
Table Top are 500kgs lighter than the GXL's. Also talk to Denco Diesel, they do a very neat water to air intercooler for the 78 series.
Another suggestion from this thread is the Safari DTronic chip.
I found the factory turbo diesel quite a handy performer for a vehicle with the handling characteristics of an ocean liner!
Geoff.

I found some figures from the Toyota website. The Kerb Weight figues are averages. These depend on what options you have fited.
GXL:
Weight = 2500 kg
Power =150 kW
Torque = 430 Nm
Troopy:
Weight = 2200 kg
Power = 122 kW
Torque = 380 Nm
Ute:
Weight = 1950 kg
Power = 122 kW
Torque = 380 Nm
I rekon I can make my own intercooler. The design considerations aren't that hard to understand - air flow, heat exchange etc. My sons's been making 'em fer years out of truck intercoolers and puutin 'em on Nissan Skylines. But I maight blow the warranty with a
home made intercooler on a brand new truck eh?

"But I maight blow the warranty with a

You may, I'd suggest Toyota would tell you anything they didn't make qualifies for "
home made" and voids the warranty!
I'm thinking about the Denco air to water myself.
Just had a call from the salesman, he must read ExploreOz and was worrying about being an arseshot greyhound. My Troopy is on
the wharf in
Sydney, whooo hooo.
He says he'll have it tonight or tomorrow.
I should be Troopying next wekend at the latest!

Get a troopy, you'll feel like you're driving a real 4wd again.
I've got a factory turbo (2002) Troopy 11 seater, not an RV. It was the dealers own vehicle and I don't think he really wanted to sell it to me - or did I fall for that old chestnut.... They are difficult to find. Was one of only 2 in Qld for sale at the time.
Yes the motor is missing the intercooler from the TD 100s. Maybe could use a bit more power when towing but we plod along anyway. Less stressful driving and you see a lot more.
These later turbo models have a stronger gearbox as
well to cope, earlier models had trouble with the trans. The yahoo troopyoz
forum is good for info.
