Where did you get that from?

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

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.

All your answers are at Toyota 1UZ-FE & 2UZ-FE V8 Technical and Performance Forums

Did the 3UZ come in cast iron? 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

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

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.

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

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
