I have a Patrol 4.2 diesel no turbo so it probably has the same general charactorisitics

depending on your k's it probably requires an injector service as they will be clogged up.  For my 4.2D patrol I had a mobile guy come out and do this for $500.

A K&N air filter will make a slight difference and save you money in the long run on air filters 

I also fitted extractors and sport exhaust after my exhaust had a couple of holes in it for about $1100 this made a decent improvement and it sounds like its going fast now lol

Your injector pump once again depending on the k's could maybe do with an overhaul but this can be quite$$$

The next step is a turbo but facts are facts non turbo straight 6 diesels are never going to be a speed machine but will go all day and all night without skipping a beat.  If its an older motor I would be a bit cautious about bolting a turbo on it.

maybe the new V8 troopy could be on the cards? If only they didnt have leaf springs in the back end!!

CHIPIT in balcatta did one for a freind of a friend i believe for about $1800 with a 3" non stainless exhaust with the egt display to

Assumming every thing else is in reasonable condition any motor will benefit from air flow both in and out.  High flow air filters to let more air in and are pretty cheap (in the sceme of things), if its a Cold Air Intake all the better. Easy to do some mods yourself which will get the cooler air in from outside, get a high flow filter and makesomething up so the air going into the filter box comes from outside the car or air flowing in from around headlights or from in front of the radiator etc. and not sucking hot air from the engine bay (not sure if you have a snorkle fitted but for a fourby this would be the go - particularly if you might go through water as the standard CAI built for normal cars might suck in water and cause damage crossing creeks etc).  Airflow out = extractors, high flow cats and a better flowing exhaust that the standard ones - see an exhaust shop..

Other than rebuilding the engine I don't know there is alot else you can do other than the turbo route,  do the sums first though as it may be cheaper to buy another car already turbo'ed.

Might pay to check some of the 4x4 forums I'm sure plenty of people on there have had the same problems and would be able to provide some good info

A mate has a 100 series , United fuel inj aftermarket turbo, and lpg fumagation,

and its still no speed machine.

In saying that it tows a 6.5 m heavy boat no probs, and still goes very well compared to a stocker.

Same question must always be asked , whats your budget?

The whole box and dice could cost heaps turbo $3-5000,  lpg $3000 hd clutch $1500 fitted etc etc

or if moneys a issue as others have said filter , snorkel , new injs and a exhuast for a mild increase.

I went from a 308 ci fj45 to a td42 gq patrol and have just learned to relax and enjoy the trip

( you dont have a choice ha!)

good luck.

You have to be careful bolting a turbo on to the 1HZ motor it will go a heap quicker  but your longevity will be gone also. A turbo adds a heap more heat to this block and its internal componenets which arent really designed for it. More fuel ,more bang ,more heat. If you do not thrash it it should be fine but i would say in heavy sand or dunes and a big right foot and i would say you will snap something pretty quick.

 I have this model and did a heap of research on it but ended up just having the reliability to run all day and night towing or not and not getting speeeding tickets. One day ill get a turbo model, one powerball

Grayzee i have the same LC and have been researching this for a while. For the 100 series as stated above chips are a no go, bigger exhaust filters etc will improve a bit. The only way to get more go and realistically you would get around 25 to 30% more power and torque is to turbo. You can buy the kits yourself but its better to get them fitted by a pro,warranties and all that. From what i have researched most turbos are pretty much the same and as long as you dont wind them up to max you should be right. I have narrowed it down to a Safari Turbo system fitted with 2.5 exhaust $3850 fitted or a DTS Turbo system fitted with 3 inch exhaust for $4500.The Safari systems have i think been developed mainly for the Toyotas but the DTS systems seem to be the ones most insstalled by the more hard core 4x4 crew,they give out a little more power.In saying that i have been warned that if you power up to much you risk diff and clutch damage but you can mess about and upgrade them as well.All depends how you drive them,you are never going to win the quarter mile but overtaking will be safer and you wont have to crawl up long hills with the boat or caravan on the back like a slug. Oh have also been told that an intercooler would give you another 8 to 10% but for another $1500 to $2000 dont think its worth it unless you live in a hot climate where your engine might overheat also if you go this way would recomend you intall a turbo timer and exhaust temp gauge and drive by them.

Id be looking around for a second hand 1-hd motor.

i recently helped fit one up to the same non turbo 100 series you have, power went from buggerall to around 150kw.

the engine code is 1-HD -FTE, All non turbo Diesels are slugs, and just fitting a Turbo kit is not good for that motor you have now

Good idea about the fte engine ,but (1) as long as you could find one (2) getting one

at a reasonble price and condition.

Heres a interesting link for swapping one out with a 1hz

Coming to the conclusion that I will just leave earlier , relax and try to enjoy the trip without overtaking anyone.

That bloody hill on way back from Jurien kills me every time. 2nd gear slog.  Oh well.

whoever built that hill owned a petrol car

I have heard good things about Dgas !

 i've been running a dieselgas australia system on my 4.2td for about 6 years. runnining 25% gas 75% diesel mix and have a range of 1400km towing my boat and 1600km with out it. thats 180L of diesel and about 35L of gas and it's a powerhouse go to united fuel injection in Redcliffe and i'll bet you a carton of Bundy you'll walk out of there with a smile from ear to ear and a truck that pulls harder then a 13 year old 

Redneck where does the lpg tank go ?

Mines on a ute so lenght ways from rear tyres to taillights one on each side and it a patrol also but as far as i'm aware they can go inside the wagon bit the tank is small so it takes up bugger all room and they also make a wheel shaped tank now that can go where your spare lives which is fine if you have a rear wheel hanger/bar setup 

 and if i knew how to upload a photo i would 

I have a mate have the lpg conversion done on his patrol and hes is spewin he wasted his money.He wishes he just turboed it.

 Meersy i have done both when i looked at first doing the lpg i got told to do a tubro upgrade first, so i did and a 3 inch exhaust which did make one hell of a differance the lpg took away almost alll the turbo lag and i and going to do it again for sure  

 Make the exhaust bigger and you will get improvement. If thats not enough then aftermarket turbo.

Hi Grayzee

Sounds bumb but dropping from 285/75/16 tyres back to 265/75/16 (or 275/70/16)will give you a whole lot more power. I forget the actual figures but in my old patrol (on the dyno) I lost about 20% of my power and torque when I increased the size of the tyres.

May not look as sexy but it will give you an instant bang for your buck.

After that, unless you are really in love with the Cruiser, sell it and spend the money on something that already has the power you need.

Spending $5000 on a turbo and 3 inch exhaust will give you great power, but depending on the k's on the motor you may not be able to turn up the boost as much as you want to get the best power.

Cheers

 i did and with a 3.5" exhaust mine goes pretty hard when it needs too....... i think too its the way you drive it sometimes but im happy with extra 10-15% power.... at least it just keeps going.....good old toyota diesel!!!! oh what a feeling
