1) Trip computer in the EMV and I think maybe dash will be run from the ECU from memory so could be hard to wire up. Aircon, radio, tv, seat memory etc, should operate as per a normal UZZ31. You're going to need to study the wiring diagrams on Lextreme to make sure everything hooks up correctly, although they won't include the diagrams for the digital dash. The dash could possibly be swapped in with a 1JZ loom - might be the easiest option.
2) I don't think there were any VVTi 1UZ Soarers. Dad's '97 UZZ31 isn't VVTi unless I'm missing something.

Thanks for the replies. Does anyone else know? I can live without trip computer but dash would be hard . Has anyone ever done any conversion on a uzz? I want to put a deposit on a uzz31 but I want to know I can swap a 1J/2J in later.

Hi Josh, I am sure you can swap the engine over, but will be a big project. I am not 100% sure but I think any V8 soarer over 1994 has a higher compression motor, on the dyno day the newer V8's got more RWKW, so something has to be different??

The 1991 V8's had a compression ratio of 10:1 the 95 model was 10.4:1 and the 97 models were 10.5:1. The 95 models came out with an extra 4kw (195) only because of lighter internals, then the 97 models had even more with 216kw with VVTi. Wouldn't worry about the differences too much, Mine is a 1991 and it pulled 240rwhp.

WHat exactly are you after Josh?
Daniel, I really want a turbo soarer but after sitting in a uzz31 I also want all the V8 luxuries. Plus I have seen a cheap uzz31. So if I had the uzz31 and converted to turbo I would have the ultimate cruiser with performance.
So Jason you are positive the 97 v8's were vvti. Anyone have pics of a vvti 1uz-fe motor in a soarer or otherwise.

The VVTi 1UZ didn't come out until 1997, while the last series of UZZ31 came out in 1996. So you won't find a VVTi UZZ31.
Ask Damian Ware some questions - he is one of the most qualified to answer the questions on electrics and dash. There are lots of people doing much harder engine conversions - your conversion should be pretty straight forward since the Soarer comes with both engines in various forms. I'm not saying it will be dead easy.
This alongside what Phil says leads me to believe v8's were not vvti.

There were about 100 '97 UZZ31s
Does this mean they are rare and special like a lesser equipped uzz32?
This v8 is nice compared to my jzz31, however its white and my 31 is black on black and far better looking I think. That, the fact that it has coilovers replacing the airbags and also that the 97 update front bar has been replaced are what is the holding me back at the moment.

The lexus engine badging is like the pics I found above.
Dave, it has the black cover like the first pic, dont know about the "S2" though?
Also Dave what else can you tell me about the 97 uzz31's? It looks like yours ie sunroof etc. Your 97 uzz31 and the green one on www.carsales.com.au both have LSD's. Is this a common feature for this late uzz31? Anyway to tell without lifting the car?

There is nothing particularily special about the 1997 V8s other than being the last of the model. They dont have any major features that earlier cars didnt have, just the usual improvements you get with late model vs. early.
post '95 cars might feel a touch more lively due to the engine tweaks, i dont think there would be much in it though.
And they shouldnt be any less suitable for low-boost charging than earlier engines. They will be less suitable for higher boost though.
That engine on the crate is not from a Soarer, and as i said any Lexus badging has come from a previous owner and *not* the factory.

Josh as Neal says there are a few small differences..different AFM...sequential injection instead of in pairs ..but lose a few things on the EMV! calendar,service ,etc but you do get a nice Japanese voice...DR
