    Default Discovery 4 Lexus conversion

    Dear All

    The recent thread re Discovery for sale refers.

    I have just spoken to Dan, ex Roverland and now Landy Guru, in CT. He built a Lexus into his D3 Tdv6 a few years ago but only in 4x2.

    He has just bought a D4 V8 in mint condition with a blown engine. He is currently planning to fit a Lexus motor keeping the std LR gearbox and transfer box. ALL LR functionality to remain as std. In order to do this he is consulting an ecu specialist in Russia to help the systems talk to each other. He is also designing a master plate that will bolt onto the adapter plate that will allow him to have a choice of conversions. Dan is highly experienced and innovative. I have asked him if I can post updates of the conversion in the new year and he has agreed. This is an exciting development and definitely makes me reconsider the D3 and 4 as a viable option.

    Let's see how it develops.

    But will it work with a TDV6?

    The V8's aren't the problem.

    Why, when ever someone does a conversion, do they opt for a Lexus V8? Are the Lexus V8's that reliable, or just easy to come by? Or cheap? It seems to be the "go to" for conversions. Serious question ....

    Dan will be doing both the V8 and the SD/TD V6.

    All of the above compared to most engines. On top of it all you get a crapload of power with fair economy (for a petrol V8).

    Agree, this is good news. Now I would consider buying a high mileage diesel knowing that when the crank goes I have options. I have kept my D2 (probably for too long) because there just was no other option. The diesels have the crank issue anf the v8s are not without their issues, which is why Dan is not putting another Jag v8 in. There are issues with timing chains and these motors are known to occasionally give up the ghost; I have seen this for myself in the workshops. The other issue is that the cost of repairing or replacing the Jag v8 is very high...

    Imagine if we could get a low mileage Lexus conversion into our Discoveries for under 100k? Suddenly becomes a bit more doable.

    If he fully succeeds he will be very busy from here on.

    A D4 v8 with a blown motor is most likely down to the timing chain tensioner fault, if that is the case a repair will be around 60K worst case, then you will have a new 5.0V8 with a shed load more power than a lexus will ever get close to at around a similar price. No electronic issues and the correct engine for the vehicle.I find it strange that a lexus with tiny Japanese horses is always seen as the silver bullet?Sorry but I just cant see the logic

    I have to agree.

    I am sure that the bulk of the conversions going forward will be diesels with broken cranks... I think Dan is using this D4 as a test bed, as he picked it up for a song.

    Even so the diesel opens up even more issues, a 2.5t vehicle designed with 180Kw and 600nM low down now being powered by a Lexus V8 with 150Kw(at around 5500rpm) at best and an optimistic 350nM(at about 5500rpm). The gearing will be all wrong, the lexus will spend its life on the redline, it will have a serious drinking problem and will spend life in the slow lane.I love all things mechanical but just cant see this as an option - I would rather source a second hand TDV6 or a new sub, spend the 120K and be done with it for another 3 years.I know somebody who did this swap in a Touareg, took 3 years and over 120K, it had 4wd but no traction control etc, made lots of noise but didn't really go anywhere except eventually the scrap yard...

    Let's see what Dan comes up with. I will report as the conversion unfolds.

    You can also do the fix preventatively, as soon as you start hearing the timing chain noise.

    If you buy a 10-15 year old D3 TDV6 with a broken crank for a song there's no way you'll fork out R120k+ for a proper long-term fix. Then a proper Lexus conversion for less than half the money makes a lot of sense.

    Not arguing with you, but lexus options are not as bad as one thinks, especially for what you pay.

    The
    3UZ-FE, is a 4.3 L; 261.9 cu in (4,292 cc) version built in Japan. Bore and stroke is 91 mm √ó 82.5 mm (3.58 in √ó 3.25 in) [2]. Output is 216 to 224 kW (290 to 300 hp; 294 to 305 PS) at 5600 rpm with 441 N⋅m (325 lb⋅ft) of torque at 3400 rpm.


    The 1UZ-FE was voted to the Ward's 10 Best Engines list for 1998 through 2000
    In its standard, original trim with 10.0:1 compression, power output is 191 kW (256 hp; 260 PS), torque of 353 N⋅m (260 lb⋅ft).[2]

    The engine was slightly revised in 1995 with lighter connecting rods and pistons and an increased compression ratio to 10.4:1 resulting in peak power of 195 kW (261 hp; 265 PS) at 5,400 rpm and torque of 365 N⋅m (269 lb⋅ft) at 4,400 rpm.
    In 1997, Toyota's VVT-i variable valve timing technology was introduced along with a further compression ratio increase to 10.5:1,[2] bumping power and torque to 216 kW (290 hp; 294 PS) at 5,900 rpm and 407 N⋅m (300 lb⋅ft) at 4,100 rpm. For the GS400, output was rated at 224 kW (300 hp; 305 PS) at 6,000 rpm and 420 N⋅m (310 lbf⋅ft) at 4,000 rpm.
