The family is about to grow by one more, its time to upgrade the 2.8D Hilux duel cab on an 80 series 'cruiser. My heart is set on a turbo diesel after a test drive in a standard 4.2 diesel. I reckon my Hilux (extractors/finer filter) had just as much punch off the line, so came away dissappointed at my first drive. Go the turbo I hear ya'll say.
I reckon I will buy a standard 4.2 and fit a Garrett turbo. Question is....is the standard 4.2 the same motor as a 4.2 factory turbo diesel.
I figure I can get better value for money with a better condition standard 4.2 diesel and spend $3k on a brand new turbo/mandrel bent exhaust than buying less of a tired turbo diesel...hope that makes sense!!
Comments appreciated.

And no....I don't care what you say....I DON'T want a Patrol...go the Tojo...!!!

It is a different engine(direct injection) the early factory turbos had big end problems and needed them changed every 100000kms so they didnt let go of the bottom end.
The std engine with after market turbo is not as quick but you dont need to do the big ens as often.(150000kms pulled some out looked like new).
I would like to find an intercooler for mine to give it a bit more punch but at $1800 to $2100 bit to much for a bit of alloy.

Hi, yes they are different engines. I bought a 91 GXL Diesel at the strat of 2001 with 149 000 ks on the clock. In Mar 02, I had the injectors done and in Feb of this year I bit the bullet and had a turbo fitted. Best decision I ever made. Certainly saves money doing it that way.

Firstly yes, the engines are different.

I've had my '91 80 series turbo diesel since new and reckon its the best investment I've made. It's got 270,000 on the clock and just replaced the big ends for the second time. The old ones still looked pretty good according to the mechanic but having done 150,000 k's on them, thought I would change them out. I too tested a standard cruiser before testing the turbo. Once driving the turbo though, there wasn't really much of a decision to make. The difference between the two where to telling. Go the TURBO. I've replaced the turbo once only after the immobiliser shut the engine down at 110kmh, not alowing for it too cool down. Besides that, couldn't be happier with it.

Thanks every one for your replies...
To change the big ends...how much did that cost, and did the engine need pulling or could the sump be dropped and done in the vehicle?

i remember in about 1990-1992 my old boss bought a diesel landcruiser and got an after market turbo fitted to save some money.
something went wrong and toyota wouldnt waranty motor as it had an non genuine turbo.
acording to the boss as i remember turbo diesels have decompresion holes(not as in a hole ) in there pistons.to lower compresion.looking foward to september(landcruiser park/fraser island)

Hi
If you can afford a factory turbo, go that way, the motors are more efficient design being direct injected, and if you can get a 95 or later, will be multivalved and no more bigend problems. Things like the clutch- twice the size etc.
However, if you cant afford a factory turbo, i would do as you suggest and fit a turbo to the 1hz.

Hi
Theres the bigger clutch to begin with, then the gearbox has different ratios to a 1hz, but thats not really a problem, just a difference. All else mechanically is thesame, bigger inlet to air filter, bigger fuel lines. If you compare GXL 1hz(normal aspiration) to 1hdt(early t/d bigend problems) or 1hdft(multivalved no problems) the only difference is the ability to get a turbo diesel auto where as the diesel was 5 speed only. Other than the turbo boost lights on the dash, they are thesame, some t/d autos came with ABS standard aswell.
All in all, many people have turboes a 1hz and been happy. I have put a turbo on all the diesels ive owned because they make the vehicle that much more driveable without loss of economy and sometimes gains.
If i could have afforded a t/d auto, i would have bought one, but settled for a petrol auto for 10k less. (thats alot of fuel)
I wouldnt be put off a 1hdt for the price of a bearing change in the maintenance schedule every 100k kms.

Can someone explain the 'big ends', are you refering to the bottom end crank bearings, or turbo bearings etc?

The big ends I am asking about are the bearings on the crank/conrod, they cop a bit of extra hammering with more power from the turbo.
