Lexus v8 into rangie

[shibby73]

Hi guys. I've been looking at getting a disco for ages and after test driving a few i've realised I must have a Range Rover HSE.

I've done a fair bit of research about them and I know ownership isn't without complications with regards to the P38A motors.

My question is (hope I don't get kicked off the forum)

Is it crazy to put a Lexus v8 into a rangie. 2001 HSE is what I want. obviously it doesn't have to be a toyota V8, but just something that is closer to bulletproof and has lots of go, and would justify the hours spent in the shed.

[Vern]

Ahh good luck getting the thing going, the ecu is rather complicated, better off working the 4.6.:)

[Pedro_The_Swift]

around 440Hp out of the crate though--
sounds sweet at 8grand:cool::cool:


I know someone thats played around with these if interested,,

[BigJon]

Do they fit? Lexus quad cam V8 is very wide across the heads.

[big guy]

I thought as much too at one stage.
I had a V6 Holden(3.8L) in a 2 door RRC.

On paper it all sounds fine but driving is another matter.
It was a professional conversion and i am sure its still around but had many issues like slipping out of low range, over heating and so many relay's it was crazy. You smile and say that can be sorted.
Sure and than the biggest issue, the motor likes to rev but off road you need the torque down low, even just getting away from the lights, it was just not a good match.

Other issues you will come across, is the HSE is a top ride, make no mistake but very complicated and to get all the electrics sorted will be big dollars.

I had the pleasure of driving a couple of p38's, one a 96 4.0L which was O.K and two later models, both HSE which basically means all the fruit.

Both drove differently, both had 4.6 motors and one a 00 and other last of them the 02 model.

All cars are different and I experienced it 1st hand.

I say drive as many as you can, as the 4.6 litre can be worked, different injection, head-flow work and extractors etc.
I actually thought they were pretty quick for such a large car and before changing anything, I would drive some and have it checked 100% before purchase. Overheating and slipped liners are a real issue and be ready to get 16-20L/100.

Nice cars though and I do believe the is a thread on here on a very low KM model that someone posted and said to be a real bargain.

Good luck.

Around 440 HP , rubbish , thats for latest 2009 5 litre motor ! you wont get one of them from Japwreck front cut boys ! try 250 hp for the 4 litre .Its torque curve is all wrong for a 2 ton plus four wheel drive . must add the right Turbo !!

[Bigbjorn]

They are a very bulky engine. Have you taken a tape measure to an engine and your available space? They are electrically complex and will be a nightmare to get properly interacting with another electrically complex (of notable unreliability) vehicle. Might be better to spend $5,000 rebuilding your Rover V8 and giving it a bit of a tickle up.

[stig0000]

shel fit,, do it,,, :D:Dwould sound prity damm good to,

[shibby73]

Well its not massive power I'm interested in, I just want something I can rely on, that makes it worth the conversion. How about a TDV6 then. or are they too expensive to buy in the first place.

What other motors would people suggest.

[Vern]

shibby, i said it in my first post, you'll never get around the computer side of it, far to complicated.
better off working the 4.6, they do strokers for these, the only main problem these engines have is the cylinder liners which can be fixed by putting top hat liners in.
to do a conversion on this car, if you could get around the computer side of it would be well in excess of $15k doing it yourself

1. It'll fit. If it fit's into a JZA80 supra it'll fit.
2. 8 grand is consetvative. Sounds better at 14000.
3. ECU CAN be hard, but if you get the right donor it doesn't have to be. The issue is the ignition, you need the matching ign barrel for the ecu security on some models. For how cheap you can get an engine, an aftermartek ecu is feasable. Trust me the toyo ecu security is crackable as well.
4. They are cheap and reliable. less than a grand for a replacement motor. Easier than rebuilding.
5. 1UZ 4.0lt alloy block (1st gen) 10:1 compression, 191 kW (256 hp), torque 353 N·m (260 ft·lbf)
2UZ 4.7lt cast iron block(2nd gen) 202 kW (271 hp) at 4800 rpm with 427 N·m (315 ft·lbf) torque at 3400 rpm (vvti model).
JDM versions produce 173 kW (232 hp) at 4800 rpm and 422 N·m (311 ft·lbf) at 3600 rpm.
Australian models produce 170 kW (230 hp) at 4800 rpm and 410 N·m (300 ft·lbf) at 3600 rpm.
3UZ 4.3lt (3rd gen Iron block) Output is 216 to 224 kW (290 to 300 hp) at 5600 rpm with 441 N·m (325 ft·lbf) of torque at 3400 rpm.

All have 6bolt mains and are as strong as an ox. Personally taken a 1uz to 11600rpm, and 550hp. And a 2uz to 14000 and 880hp.


This something I've been toying with for a comp truck and my own D2 for some time. 2uz with vvti and 200ser cruiser box/tfr so it bolts straight up.

There was a guy who lived on the Northern Beaches of Sydney who fitted one to a RRC several years ago.
He was on this forum but I haven't heard anything for years.

Zuffen on OL?

Edit: Just checked, and it is. Modded motor, 235 kw at the wheels. This is his quoted drivetrain, etc:

"Patrol 4.2 5 speed and full Patrol driveline.

I made the transmission adaptor myself and it has less than 2thou runnout.

Fully engineered and signed off by the RTA in NSW. The only "modified" item on the engineers report was the chassis everything else is listed as replaced.

The Autronic SM4 ECU was wired by Quickfit in Hornsby and has since been modified by me to make it work how I wanted.

Hijack over."

cheers, DL

Iive scoured the net on the topic of P38 engine swaps, there is lots of talk about what would be good etc but im yet to see any one who has actually done it. (apart from small Diesel, that is a common swap in the UK)

The LS3 Chev 6.2l is a good option, standard it has 430BHP, few hundred more gets the 480BHP version, new crate LS3s are around $7k.

Anther choice is to go V8 turbo Diesel, 6.6l Duramx or similar, 300BHP 11l/100km standard, has been done to a few late model GU Patrols, the out come was awesome.

The Becm is goign to be a problem, getting the computers to mate will be difficult but doable, then the drive-line will need to be strengthened, gearbox and diffs would need to be replaced, transfer modified/replaced, CVs and axles and brakes.

Im not trying to put you off, i would absolutely love to see it done and i believe it is possible, just expensive, i would say $20-25 000 all up if you do lots of work your self.

[clubagreenie]

Thats a good price for a conversion. The last 4.7 toyo I did cost 30K just to build.

[shibby73]

Many great opportunities out there obvious. some costly, some extremely costly.

Look, I like the 4.6L motor i think it sounds great and would have enough power.

I just want a reliable Rangie, tis breakin me heart! Dont really mind about fuel consumption, I have another car to drive to work.

Has anyone rebuilt one with the top hat liner fix? I would buy a crate engine and put that in, except they all from U.K. Hows the overall cost and end product, has somebody done it? Surely. speak up please, especially if you're in melbourne eastern suburbs!

[clubagreenie]

When I was looking (nneding) to replace mine looked at the top hat option. TR Spares (Syd) was around $3500- for a short 4.6 hatted.

Which option did you go with?

[pando]

Hi Guys,

Something I have learn't from this forum is supposedly "deal breaker" issues seem to be easy fixes when it comes down to it, especially when it comes to reliability SNAFU's concerning the green oval as most can be circumvented with a bit of time, asking questions and elbow grease.

Personally, if you're super keen on a P38, work (the 4.6) and address (electrical) the current and well documented issues and end up with an awesome bus "for all occasions".

Wanna a conversion? Would probably suggest a chev LS series if you're after a petrol V8. Can't comment on this directly sorry as I don't have one or have driven this particular setup but having driven both P38 and LS in a Patrol can surmise that it would be an awesome marriage.

FWIW, the dunnydore guys who have been flat out with this conversion for a few years now spruke changing the diff ratio upwards as the 1UZ-FE has poor down low pep against aussie and USA V8's.

[clubagreenie]

Ended up with a crate 4.6 short motor for $2200-

Where did you get that from?

There's no more, or I'd already have offered it for sale (at 3000-)

Did the 3UZ come in cast iron?:confused: Mine is ally.
Personally, I wouldn't fit one to a automatic RR of any description. Too peaky even with the VVti it would be wrong in a 2 ton 4x4. Great in a TR8 though...!

You're right sorry, transcruiption of information error. Major advantage of these engines are despite being oversquare, there's room to go further.

Also their big ends are larger than SBC so you can destroke and overbore, reduce rod angles and bearing speeds all in one.

The vvti can be played with (via Autronic) but you need to be brave and cut two sensor lobes off the cam. The lobes are at 0 and +/-135deg and it was impossible for to crack a solution with the guys at autronic. So we just used a single reference and it's simply on/off. You should see the curve change at 8000 when the vvti hits.

Yes, having had a 1UZ in a LS400 and now a LS430 I am very impressed with these engines. I am also very happy with their factory performance and efficiency, but amazed at how far aftermarket fiddling will take them:eek:

Any more info / pics etc on the 1/2/3UZ mods you have been involved with? I am interested in how 11,600rpm will sound:p:o

quick hijack for justin.....

I remember years ago in street machine mag that a yank put a 4L lexus in a home made kit car. He had a whipple supercharger with 50psi (yes 50) boost, making somthing like 2000hp. The bottom end was mainly stock too. If you search the interweb for it, i think it was called the GROUND FIGHTER LE1, as it had the windscreen from a fighter jet.


Hijack over......


P38, put a LS1 in it, heck john davis motorworks did it 10 years ago. Overfinch did it when they were new. Cant be that hard. I am told MARKS do a bellhousing between an LS1 and HP24.

I realise that you've purchased a crate motor now, but for the others who want to do such a complex conversion, then i suggest that you build your own ecu, might sound tricky but, megasquirt II is pretty good, and should cover all bases


factory 200kw in stock form is pretty good for the quad cam lexus v8's

i agree with that, megasquirt has been used to run many lexus v8's and can be bought fully assembled for a very reasonable price

The ECU s not an issue IF you get the right donor. Not all the toyo/lexus models have the same ECU security. Look on ToyMods Car Club (http://www.toymods.org.au) and Toyota 1UZ-FE & 2UZ-FE V8 Technical and Performance Forums (http://www.v-eight.com) and you'll find info on what donor to ask your local engine importer for.

You use a crown, not a soarer, then you can utelise the factory ECU much easier

[andyrover]

If you really want a V8 Rangie, have you checked out a nice L322? Now going cheap and no conversion required...
