G'day all,
Im the proud owner of a 2002 1hzzzz Lc105 std wagon. Im looking to do an engine power up and after much research on bolting on a turbo, (Vehicle done 37,000) was at the wreckers looking at some seats, and after seeing a one year old GXL TD 100, started to think... What if I bought engine from a wrecked TD100 with 151 Kw turbo deisel, and bolted that in instead???

Anyone researched/ done this one ?? wondering about will it fit, gearbox ratio's diff ratio's radiator size, engine management etc???

I'm considering this because it will be a factory engine turbo instead of the worry of blowing the 1hzzzz, and will be 151 Kw, newer technology, as apposed to 120 or so Kw the turboed 1hz would be.

Anything else I should consider?? Looking at ball park of 10,000 for the new motor, with about a 4 grand trade in on the 1hz with 37,000 on the clock.

What do you reckon???

I've asked Toyota about this before and they said it is posible.

I wanted to do this to a GXL 1hz diesel last year.

You'd have the best of both worlds. Ridged front axel with the mighty TD.
Whack a bent mandril 3'' exaust, bigger intercooler, and a Tunit or the like and you'd have close to 180kw. Sounded bloody good to me at the time.

So yes It's possible but from what I found out bloody expensive. Altough I wanted tojo to do this conversion in house and with a new GXL diesel and a new TD engine. So mabey hence the qoute I got was alot.
Too much money for me to spend at the time so I didn't go ahead.
Don't listen to any nai sayers mate. If you can afford it..........Do it.

Just turbo the existing engine. Don't go making a rod for your own back!

I know of 6 vehicles (from 75 series, to standard 80 series to standard 100 series) that have pulled the 1hz out and put a 1hdft in.
This motor came out as a multivalve t/d in the 95-98 80 series, and is non electronic. One of these said vehicles is a hzj105 like yours. The conversion is a bolt in affair, with your motor being worth x amount to sell afterwards. ask the question on www.lcool.org and you will get replies.
Putting a turbo on yours will increase power, but nothing like the spread of torque these motors have std.
The 1hdfte in the 100 series will be too hard to fit, though essentially a 1hdft with electronic pump, they wire into alarm systems and electronic pumps in the tanks, and it is all too hard.
Good luck, there are inporters of these motors(from japan) at the gold coast.
b4 you bag me out, walk a mile in my shoes, then your a mile away and have my shoes :)

Do the sums again.

A 1HD-FTE (from a 100 Series) engine costs about $11000 and the loom+ECU is about another $5000. The gearbox in your truck (R150F) is the Prado box and won't handle the grunt, so you'll need an H151F box (the H151F in the 100 has different ratios (taller?) to those used in the 80 Series). Even turboing your 1HZ will push the R150 to its limit (which will be shorter).
I can't recall if the transfer case used with the R150 will bolt straight up to the H151, so watch that too. The transfer is not quite the same between 80's and 100's although it's the 'same' model.

Maybe a trade of your engine+gbox+tcase for the 1HD-FTE engine+gbox+tcase+loom+ecu is the best option.

A turbo intercooled 1HZ will never equate to any of Toyota's 1HD motors. Mind you, a turbo 1HZ is still heaps better than a std 1HZ.

The older 1HD-T and 1HD-FT motors from the 80 series didn't use any ECU and will still start quite happily in cold weather without using glowplugs/heater screens. They don't make as much power as the 1HD-FTE either.
