I wondered about this. The auto, is the same style as the Surf Auto, so I suspect it would bolt up with a combination of the 1UZ bellhousing. Having said that, I dont know if it is ECU shifted or not.

I think the best way to do it would be adapt the 1uz auto to the transfer
basically using the adapter and maybe the output shaft from the auto if needed

the reason being is the 1uz auto is electronically controlled by the ecu or ect (depending on which 1uz you are going to use)
it will drive much more nicely if the 1uz has the auto behind it that was intended
putting autos behind engines they were not set up for causes head aches ie 4cl diesel >v8 petrol the shift is going to be set at diferent rpms and loads
if you need help with the wiring i have built many standalone looms for these engines so its just a matter of hooking up a couple of wires
pm me if you need

Yeah the actual housing on my dads is the same as the gearbox housing in my 1uz.
sooo... it is doable.. but yeah... Effort.

Whats this replacing in the 120? 2.7? TD? I reckon you'd be crazy to replace the 4L V6 with a 1UZ. The V6 is a sweet motor and really well matched to the vehicle. If anything you'd be better off trading your TD or 4cyl on a V6 one and save lots of $$$$ and headaches.

3.4l v6 im just thinking out loud that the moment

[RAY185]

not all 120 prados had the 4ltr some early ones had the 3.4 v6 its 2005 and after that had 4ltr

3.4l v6 im just thinking out loud that the moment

Oh ok, I was under the impression that the 3.4 ended with the 95 series in 03 and the 120 came in in the same year but only in the 2.7, 3L TD and the 4L V6. I own an 04 with the 4L V6 btw.

I can see why you would want to replace the 3.4L.

You are correct Ray, the 120 series never had the 3.4l

95series = 5VZE -3.4l
120series= 1GRFE -4.0l

First appeared in 2002, this model included a re-designed front suspension to address reliability concerns of the previous generation, and an all new body designed at Toyota's ED2 design studio in France.

In August 2004, the 3RZ-FE was replaced by 2.7 L (2694 cc) 2TR-FE and in July 2005, 5VZ-FE was replaced by 4.0 L (3955 cc) V6 1GR-FE with 5-speed automatic transmission available in late 2005. In North America, this model is known as the Lexus GX 470 with the 4.7 L (4663 cc) V8 2UZ-FE engine.

Not sure what market they are referring to wherever you copied that from but I don't think its the Aus market.

Looks like another country specs.

Hey Ray, some early prados (90) series, had a 4 cylinder petrol too.

Yeah they sure did champ.

My wifes 2003 has the 4.0lt

[mmaaxx]

I can confirm that NO 120 series Prados in Australia ever came out with the 3.4 V6....they had the 2.7 litre 4 cycl for bout 2 or 3 years before it was dumped and they had the 1KZte early on before the D4D got put in. The 4 litre v6 has always been standard fitment on these.

ok my one is a 2003 it has a 4.0lt

Turbo that!

[killalux]

If you were gonna do it I would use the 2UZ, make it worth the effort. Also they may be a little strict using a early model engine, in a 03 model vehicle.

I also own a 120 with the 4.0L and had the 1uz in my old Lux. I wouldnt bother changing it. IMHO for the amount of work, effort and inherent problems any engine conversion brings it wouldnt be worth it. I also think the 2uz is not as good an engine as the 1uz and the fact that it isnt an alloy block the extra weight and again hassle wouldnt make it worth it either.

There are supercharger kits for the 4.0L that claim up to 280Kw if you want extra performance that is the way I would be going.

[mutilated]

Short wheel base VZJ125 had a 3.4l V6 and also LWB VZJ120/121 had the 3.4l V6 the 4.0l V6 was in the GRJ120 2.7l on the RZJ120 3.0lT/diesel was in the KDJ120/121 and the KZJ120.
