1HZ to 1HD-T/1HD-FTE Conversion in 80 series

[The Fish]

Has anyone done this conversion before? Would think it wouldn't be too hard as I already have a H151F gearbox from a 4.5L tray.

Reason for doing so is the 1HZ has 180K's up and I'm a bit hesitant to spend the $$$$ on an after market turbo with intercooler on an indirect injected motor that is limited in power increases without sacrificing motor longevity.

Hopefully I can pick up a 1HD-FTE at a price that would make this conversion a viable option considering the initial power increases that would be gained let alone the potential power increases possible down the track. Also once I have the $$$$ to further enhance 1HD-FTE, after it's been in a while, it will be still relatively low k's and not old and tired.

What do people think? I'm sure i wouldn't be the first to go down this path!

Does anybody know of any 1HD-FTE or 1HD-T prices?

I'd stick with the H150F from your 1HZ, the lower 1st gear provides better off road crawling performance, and 2nd gear is low enough for most on-road take offs.

180,000 isn't that high km for a 1HZ and if you shop around you can get a turbo installed for not much more that 3k, for a 1HD-FTE including wiring and coumpter I'd guess you'd be looking at around 8 - 10k, plus the drama of getting the electronics right.

the 1HZ with turbo makes a strong and reliable motor so long as you don't go overboard - 9psi without intercooling yields up to 135kW /390Nm which exceeds the 1HD-T in stock trim. 12psi with intercooling obviously yields more impressive results but the gains above that are severly limited by the indirect injected engine design.

of course if you want 200kW + then you'll need a direct injected donk to start with and if you want to go that way go for a 1HD-FT (E) now and start saving for intercooler, bigger turbo, tuning etc.

the fitting of the motor is a simple bolt in, you'll have no drama with engine moutns, drive line lengths or shifter positions.

Thanks for the reply dumbdunce.

All points you make are relevent but I think if I'm going to get away from the stock 1HZ I'm going to want to do it properly. I don't want to turbo the 1 HZ only to find I want more KW's and already spent the $$$ on the 1 HZ and have it at its limit.

In saying that I like the 1HD-FTE option with H151F gearbox as it has the larger clutch to handle the greater power. I'm not much into slow rock crawing so i don't think the higher 1st gear would be a problem.

Also have heard that I could change the 1HD-FTE pump back to mechanical and thus eliminate most of the drive by wire electronical dramas. Less economical but I'd be after KW's not economy as much.

Any idea where I could find the specs on the 1HD-FTE and where I could start looking for one

Also what would you expect I would get for the 1HZ and gearbox

[dumbdunce]

if you're going to go mechanical injection then best off getting a 1HD-FT (1995 - 1998 80 series multivalve turbo), will be cheaper than the electronic injected 1HD-FTE and you won't have to source a mechanical pump, or ditch the electronics.

start with importers in your area - I'd start with 3WJ here in sydney but you should be able to find one down there.

you can use the R150F gearbox with the big clutch from the 1HD-(F)T(E), but if you like the R151F, go for it.

should be able to get at least $3k for your 1HZ and gearbox, maybe more if t's all in good condition.

good luck!

Hi
On the 80 series list www.lcool.org there are a few 80's and 1 105 with transplanted 1hdft motors, from japan. All bolt in using the 1hz starter and not much else is different. One 1hz with 5 speed was selling for 3500, so 2800 would be a good starting figure for the 1hz.
The h150 would be a better box if you want to 4wd. Foe some reason, the turbos got the higher first that the petrols ended up with. Unless the h150 is pre 9/92 i would use it over the h151(synchros on early boxes are sus). Also, you can buy an off the shelf clutch plate with the h150 centre and the 12 inch outer diameter that the hdft motors use. Flywheels are drilled different for clutch from 1hz to 1hdt, otherwise interchangeable , Bellhousings r same, etc etc. You could put a Daycon h/d clutch behind the hdft with 1hz flywheel (done b4) and the hdfte can be turned into a hdft using hdft pump, why would you do that??? just get a hdft, look at the importers in gold coast area, 8k for a motor.

you mean daikin don't you

Andrew

my guess was pretty close then eh

[The Fish]

Thanks dumbdunce and dow50r for your advice, I can now go ahead and start chasing some prices with a bit more understanding of what I'm after.

[NICK]

Does anybody know of any 1HD-FTE or 1HD-T prices?

both motors no exchange,

1HD-T 9,500
1HD-FTE 15,000+

i sold a FTE, well 2 of them to a place in PNG both with less that 20,000 on them and got $36,000 for the 2. You want one out of a 78-79 series as they dont have the security coded pump like the 100's.

As a conversion you will need everything down to the instrument cluster, the 3 computers and probably the 2 wiring harnesses. thats for the FTE. the HDT is alittle more straight forward.

We currently have a 1HZ with a safari after market kit front mount etc if you are interested.


NICK

[NICK]

and if you can point me in the direction of a FTE for 8000 i will take 3 tommorrow.

part out the intercooler kit (not the turbo)? $$? (80 series kit?)

looks like I was a bit low on my guess then. ah well - it's not my money. what's a 1HD-FT worth then?

That's what I would be interested in - a 1 HD-FT

most places will sell them for around 10,000 with a rebuilt bottom end, exchange only, seen as there is no exchange you can add about 3000. Im sure if you shopped around you could get one down around the 8 mark but that would be a JAP import with really no history and high Km's. Honestly it is hard to place a price on them as it depends on the above and what is available at the time. some people will buy on price and some will pay more to know that they are dealing with a good business and getting a warranty that will stand up. To a 1HD-FTE cheap you would be best to buy a complete vechicle from the auctions, most with 80000-100000 on them will go for 12-15grand, once parted out you should make back about 5 grand but then do you want the hassel of not be able to sell the parts?

Personally if it was me i would buy a BRAND new 1HZ from toyota, reco my pump and fittings and buy a new turbo kit. this way everything is new and you well send around the 10 mark but atleast you know what you go for your money.

If your after power, put in a chevy motor or holden 5 litre V8

Although what I'm after is a reasonable increase in power I don't want to totally forfeit economy for it. Converting to gas only reduces ground clearance. This way I can get the power I'm after from a factory motor (with improvements) and still retain as near as possible my current economy.

[Goodsy]

Just put a chev in it thomo. You know you want to.

You will never retain near that current economy once you change over to the petrol engine.... i've heard a lot of my friends who own petrol 80 series wished they didn't go that route. So bascially you want your fuel figures to be similar to now best option i would go is a rebuild then slap on a turbo kit plus intercooler now that'll give you plenty of power. Just like what the others said here

Mad Cruiser - I meant going for a 1HD-T or 1HD-FT option and still retain close to my current fuel economy.

[deRanged Rover]

If you're interested I still have my factory turbo motor, turbo instrument panel and wiring loom all for sale as well as most of rest of vehicle.

email me on golenia@kooee.com.au

[The Fish]

For all those interested I just got some prices from Southern 4X4 Dismantlers here in Melbourne

1HD-T $7,500 Rebuilt (To what extent I didn't ask) & Change Over

1HD-FT $8,500 Change Over

Which donk gets better results (kw/torque) from extra work to the turbo/intercooler?

[dow50r]

The 1hdft get best results as it has more air in the head, and the injecter placement is better for (upping boost) getting rid of heat.
Also there is vertually no bigend problems with these over the hdt.
check out www.lcool.org/technical
Andrew

[deRanged Rover]

Compare that with my price of $4500 outright for a motor that is guaranteed to be running as good as new - you can still listen to it running in the vehicle!

[dow50r]

Did u get my PM DeRanged?
4500 is a good price and the hdt - it is a good strong motor to boost to 11 psi.

No no PM has come from Andrew! Try again or email me please.

brand new 1hdt from toyota for $8690

price list last updated 03/08/2003, might be even cheaper if they have any left

this certainly makes the quote i had for an imported 12HT for $8500 seem rediculous

[deRanged Rover]

short or long or long complete

May need to add $1000s to make it a complete long motor?

that price from toyota would not include anything but the long block - no fuel pump, and probably no manifolds/turbo.

[slowhilux]

Priced up a COMPLETE 1HD-FT about 2 weeks ago, from Castle Hill Toyota

$14980

includes manifold, turbo, pump, injectors, inlet

does not include alternater, AC or PS pump

vac pump? given the choice I'd leave the toyota turbo and put something decent on there - like - ANY other turbo.

[slowhilux]

I hear ya brian. Garret DO make a direct bolt on, or you can also choose the option of getting the std Toyota one rebuilt with Garrett internals, wheels, etc. Cant remember whether or not that was with a vacuum pump....
