1KZTE Hilux vs Surf

[sabre_01]

What is the difference between the 1kzte in the hilux utes and the one in the surf. The figures I have seen say the surf has a higher kw output. The reason I ask is that it is hard to find a manual 1kzte surf to do a engine swap into a 2.8 hilux ute. Most 1kzte hilux utes I have seen are manual which would make the conversion easier. Is it just a mater of tuning the hilux engine to gain the same figures as the surf.
Also as another option, does the manul 1kzte gearbox and bellhousing bolt up to a auto surf engine.

I think the surfs like the prados have intercoolers

only some of them do so you've got to watch that. Surfs with a scoop do and surfs with none dont

[IcedJohnno]

The 71 & 78 series Prado's don't have intercoolers either sadly.
The 90 series ones do, not sure if all do though.
Lineside were offering a kit to fit the factory one including ALL the bits necessary including rocker cover and throttle cable for $600 early last year, was cheap. Did not have the money Dammit, had just got a mortgage.

[sabre_01]

The figures I have are hilux ute 85kw
surf (non intercooled) 96kw
surf ( intercooled) 103kw
So are the ute and surf engines exactly the same with a bit of detuning for some reason?
Does the ute run a R-series gearbox and if not is that the reason for the detune.
Just trying to get options for a engine swap into my 2.8. and the best way to run a manual box. Heaps of manual utes out there and if it is just a matter of changing a chip or computer tuning to gain the higher kw of the surf then that looks like the best option. Any help welcolm.

As I understand it the 1KZ Hilux's run a solid flywheel unlike the Prado, Van and Surf. This would make that motor worth getting cos otherwise the first thing you need to do is replace the two-piece flywheel and solid clutch assembly with the conventional type. (Two piece ones all fail)
I suspect there is no difference in engine design but may be in electronics, but don't know this. Others will though.
The early Prado like mine is also 96kW.

If you are keen, big gains in the mid range torque can be made through some careful head & manifold porting. I also welded up the exhaust recirculation entry point into the inlet butterfly bowl area and ported all that too.
My truck now gets from 100 to 140 km/h about 0.8 km sooner. Have yet to mod the exhaust or the turbo outlet housing or put on the much needed intercooler.
Haven't yet played with boost pressure, fuel pressure or fiddled with the 'tronics box either.

your best to get a 94 /95 kzn130 weather its manual or auto its a mater of luck at what comes up , one thing i do know is its getting harder to get a low milage one, if you get that model they are the same truck as the 90 s hilux every thing bolts in ,thats what i did i would nt get to hung up on a auto the guys that have them love them .

i've got a surf with the 1kz 5 speed and a cruiser with the 24v turbo, had a race and the surf surprised me, could just about keep up with the cruiser, took the surf 4 wheelin the other day and i love the 3litre, it would be my favourite diesel engine

[lexlux]

dont quote me but i think at about 1996 the heads changed they are bigger with longer valves ,one thing i do know is the later model ecus eg kzn185 dont run the earler models kzn130.

Thanks for the info on the solid flywheels in the hilux utes IcedJohnno. There must be someone out there that can answer the kw issue. Thanks for the replies so far, we will get to the bottom of this issue sooner or later.

The 03 hilux utes (last of the old shape) did run the R151 box with the 1KZ-TE.
If you have an earlier 1KZ, watch out for head trouble. I heard rumours that toyota redesigned those heads four times before they got it right.
Increasing power increases cylinder pressure which will bring on any trouble sooner. So make sure you've got the spare $3k or whatever extra if you're increasing fuel and boost.

Shame they delayed bringing the 1KD engines here for soo long. Same block but direct injection and common rail. Fuel economy and power both seem about 20% better.

[sabre_01]

Has anyone put the new KD engine into a LN106 yet. If they use the same block as the 1KZ-TE then engine mounts would be the same Suspect the worst of it would be the wiring.

hi, i done the conversion my self just before xmas but i managed to get 2 surfs cheap from turners damaged auction one manual one auto and should hopefully be able to recope all my cost when i finished wrecking them out, i put the manual one in and love it but you have to get the kzn130 as the kzn185 gearbox has front drive shaft on the wrong side. as for the kw difference it may be due to the auto box but i'm just gessing as i know subaru had different cams & ecu's in the auto models to make up for the power loss in the auto trans so you still ended up with the same kw at the wheels may be the same with the hilux's but i'm just guessing. if you need any help or tips with you're conversion give me a call on 0211055850 simon

[sabre_01]

Thanks for the offer Simon, I will ring you later in the week and set up a time for a look under your bonnet if thats ok. Just trying to get all the info and options I can so that I can get all the bits before I start and limit the time the vehicle is off the road. Your idea on the kw rating seems to be the best (only) theory yet. Makes perfect sense. Can anyone confirm if the 1KZ-TE hilux utes all run a R-series gearbox.

I can't confirm that they all do. But I can confirm that my brothers one does.

[sabre_01]

Is there an adaptor plate to mount a LN106 gear driven transfer case to a KZN185 manual gearbox. This would then put the front driveshaft on the correct side and also allow me to continue running my transmission brake. Also if the dual mass flywheel fails and I change to a solid flywheel can the same factory clutch be used or does this need to be changed also.

[1rugger]

try marks adapters in aussie.

i've been told that the chain triven transfers are weaker than the gear driven cases so i was look at the same thing but bit to expensive for me to bother at this stage. .

don't know about the flywheel but would imagine it would.

[sabre_01]

hey Simon, havn't forgotten to ring you, just been busy. Whats the best time to get hold of you. Sounds like you have already done and looked at all the things I am looking at doing already. Do the KZN130 and the KZN185 transfer cases have the same bolt pattern with the side the front driveshaft is on being the only difference. Whats the best radiator set up to run. Keep the 2.8 diesel one, use the one from the KZN185 or buy an alloy one and run an electric fan

Hi there, The import 90-95 series Prados had the intercooled 1KZ-TE with 102.97 kw and 333 nm, The intercooled 1KZ doesnt have alot more power but the extra torque makes them preform alot better than the older wagons without the intercooler and the auto/1KZ combo that most of the Prados/Surfs is a sweet combo and works so well. 90-95 series imports also had a larger radiator to help with cooling issues/cracking heads etc

The nz new Prados didnt have the intercooler and are usually manual.!! And as said in a previous post some of the 185 series Surfs had the intercooler and some didnt and the bonnet scoop is a give away for the intercooled models

Cheers

[haydgq]

And forgot to add that the 71-78 prados with the 1KZ had 95kw/289NM.

best time to get me is usually between 2pm-6pm. not sure about the bolt pattern on the transfers but the kzn130 auto & manual are the same pattern but run different shafts so i would imagine the kzn185 would be the same with different shafts again. as for the radiator i was running the surf radiator but it stuck 50mm est out bottom of chassis so not surprisingly i took it out on a rock so i am now running the 2.8 radiator but you need to get it modified which is only est $100 to get done by race radiators. how ever if you want to spend some coin a custom alloy radiator with electric fans is by far the best way to go.
