Outer Limits 4x4 Board

how do the non turbo 4.2 diesels(02 model) take to being turbo'd... i want a good relable ute but the turbo ones are still rather dear in the same age. was looking at 02 model with 170k on the clock. would turbo down the track...

regards kane

seen this on ebay the other day http://cgi.ebay.com.au/Toyota-Landcruis ... hId,cheers mick

It would be a 1hz engine your talken about?

A mate and i have turbo'd 3 of his 1hzs in the past and latest 105 series just the other month, each one for a $1000 complete and $160 for a proper tune if you want

thnks fellas.it will be awhile b4 i buy one,but was wondering if i should just safe for the turbod factory as there quiet bit dearer

hi just wondering how you turboed the 1hz for that price, i have an 80 series i want to turbo soon, just looking at my options for now

If it were me I'd save for the stock turboed motor. You'll getter better fuel economy and more power out of it than a 1hz will and it'll actually last a pretty long time compared to a 1hz with a turbo strapped to it.

you will get less power due to the compression being lower on the factory turbo in comparing the single overhead cam diesels

$380 for turbo manifold and gaskets(only change the front half 4 port)
$300 for a second hand CT26
$200 for the braided water and oil lines
$100 for plumbing the intake rubber bends and go to a exhaust shop for their cut offs to use as well
weld a flange to you old exhaust to bolt up to the dump pipe
i think thats about it

Can the stock 1hz N/A manifold be used with a adapter plate? in other words, can i strap a ct26 or something to a stock manifold?

The 1hdt will actually last for over 50,000kms and will easily take a lot more power. They did lower the compression for a reason too.

Compression is the only thing important to make power. 1HD-T has lots of different components to the 1HZ, particularly the head.
1HD-T is direct injected and capable of more power than the 1hz while still staying reliable,
Boost them both and the 1HZ may make more power psi for psi ?? I dont know, but I would bet on the HD-T holding together longest at high output.

I'm not saying the 1HZ isnt capable of high output, it should be easier to acheive in the 1HD-t ie bang for buck and reliability etc.
The 1HD-T engine is still being built, but as a marine engine by Yanmar and they put out roughly double the power that it does in the Toyotas



The turbo in the Ebay link is a chinese copy, location Shanghai, USA???

Also the number cast into the exhaust housing is incorrect for a landcruisser CT-26, there is lots of different versions of CT-26, its anyones guess what that one has been copied from.

Kitika, I think you dropped a zero

I know of several 1hd-t with over 500k on the clock and still going strong.

Hi all...Thats the smartest thing you could do,Is to save up and buy a factory turbo'd engined cruiser.I learnt thru experience.

That's what I mean the 1hdt will last over the 50,000 which is all a turboed 1hz will last! I've had a supercharged 1hz which had low EGT's low boost 8-9psi and it still sh@t itself after about 50,000kms. Bad idea turboing an N/A diesel when you can get a stock turbo built engine for about the same price of a turbo setup for the N/A motor.

yes a factory turbo motor will last longer but a turbo hz in my experiences will still last ages if done right
a factory turbo has less tourque than turbo 1 hz untill in boost due to the low compression thats why fact turbo patrols are so gutless untill in boost compared to a aftermarketd turbo patrol
after market tubo kit you still keep your high comppresion motor so you still have good low low tourqe and when boost comes in its even better

Hi all...The Patrols mite be like that.But a stock HDJ 79 compered to a HZJ 79 with a turbo with EGTset at 550 deg c max doesnot go as good as a HDJ79.The 1HZ suffers from running hot in extremes with a weak gearbox to go with it.To set the EGTs on the 1HZ down to about 520 deg c Max they still run hot in extremes and are awfull to drive,real laggy.

I'd say its more to do with the factory exhaust on the Patrol. I just changed mine the other night and the factory dump pipe is so restrictive its not funny.

As i posted above in comparing the 1hdt motor and turbod1hz the 1hdft and hdfte not even close to compare power etc they are are way better motor speacialy with their double overhead cam etc

in comparin a mates aftermarket 4.2 turbo patrol and a mates fctry turbo ute the after market pisses all over it from top to bottom and the ute has a 3" exhaust and fueld up a tiny bit and its still gutles and over heats on cold winter nights when off road

i assume these are expensive? purely for curiosity's sake, could you buy one of these and put it in a car? ie, compliance wise and fitting up to a gearbox etc?

I think they produce that much more power is because they are intercooled by the ocean so they can turn the boost right up. I read that somewhere on here I believe so I don't know if that's true.

my 1hz has had a turbo on it for 100,000 now and still going VERY strong. so im not sure where this 50,000 stuff comes from.

its running a dts kit with 15 psi, i do around 1000k`s per week.

Finally someone not dreaming!

1hz can put out 150% for yonks as long as the cooling system and EGTs are kept in check.

Too many people dont look after their cars and ask over 100% of them... thats why they blow...

Cooling system as in radiator and intercooler etc?

i just bought a quad core fat mother fucker of a radiator, 800 buks and its all soldered brass! preparing for a boosted 1hz..

X2,
I had the the HZJ75 ute turboed, it had done two engines prior to me, had a good engine fitted and lasted 50k with me, i liked the power but like reliability much more, opted for a 79 RV and so far havnt looked back,
Yeah cost a bit more in the short run but i bet im a long way ahead of what the old one would have owed overall

The hdfte is not double overhead cam

so are you trying to tell me they have 4 valves per cyl x6 running off just one cam ...... i wonder why there rocker cover on the 1hdft and 1hdfte is twice the width as the 1hz and 1hdt ... i think you will find its wider to hold the 2nd cam mate

Hi all...Im just wondering if you guys have pulled down a 100 000 klm turboed 1HZ ?

Fuel is the catalyst...

Too much unburnt fuel, high the EGT's... High EGT = Kill engine (ANY engine)

Shit oil, shit 1hz donor and too much boost running through a untuned engine will kill it.
