YES! also

I'm also planning to do this conversion into a 260Z (although a 2+2), and I've been doing the research for this swap for a couple of months now, and so far it looks good. Are you in Aus or US? I've also seen a photo of a GTO replica like the one zxgts is referring to (yellow?) and I've spoken briefly to a guy that has put one in his zcar (a 240Z i think) on another forum. Well done, it looks like a really good option for a transplant for the reasons zxgts mentioned - like the trans kits available and the new s/c kits also available over here (http://www.forcedairtech.com.au/lexkit.htm). So, are the results as good as I'm hoping they are?

i am in australia. mine is a 2+2

it is a pretty easy ( every thing is relative) swap well it fits and the mounts are not to complicated. does need full custom exhaust. the wirring is the hard bit i am running wolf. If you run an auto there is no place to put the gear shifter.

i will try and post some photos, soon.

i had it running but the tailshaft let go on the dyno not pretty a couple of photos here if you are boored

Isn't there a 4.0 lexas motor in one of the Z's featured in the JTR book?

 

Is there?? I might consider buying one now if they have some useful info on it ...

The JTR book doesn't have any info on it other than to say it was more expensive than a SBC swap and had less potential for HP than a SBC. They showed a picture of the engine bay, clean looking swap.

 

Do any of you who've done this swap have any pictures of how you mounted the engine and other information such as transmissions used, radiators, sumps, etc.

 

I live in the states and these 1UZ-FE motors can be had at very reasonable prices. I'm in the middle of an LT1 swap right now but a friend of my son wants me to build a car for him and I've decided I want to use the Toyota engine if I do it.

 

Thanks

The 1UZ has potential there are plenty of 350 RWKw twin turbo and supercharged vehicles. this motor takes forced induction really well. It would make a good NA motor as well with cams and flow work. check out lextreme.com if you want to know the potential of this motor.

 

i will try get some photos if i email them to someone can you post them for me. i will try and do a detailed write up as well. early next week.

Shame on everyone here. As many times as I have pointed you all to the photo documentation I did on the very first? Lexus twin cam 32 valve V8 engine into a 240Z back in 1998 and ya'll can't remember it? Tsk tsk! Two of my photos of it have been linked into my ZPARTS.COM home page for over 5 years now!

 

ZP home page is at http://www.zparts.com/home.html Scroll down toward the bottom of the page to a links that mention Lexus V8 in a 240Z and Corvette tail lights in a 240Z (Note: It's midnight now and my hosting company is working on the web server so you may have to try the link tomorrow?)

 

OK the drill is that the guy who did the first swap, that some of you have seen the black and white photo of in the JTR manual, is located in the Joaquin Valley of California. According to what I remember him telling me the first time I met him was that he started his project back in 1990 or 1992?, sought the help of JTR along the way, but became disenchanted with how JTR "treated" him and his project.

 

Guy told me that he was an engineer in a specialtly field in Silicon Valley and that it took him something like 5-7 years to complete his car. After much care and planning he dropped in the Lexus V8 with original tranny, chopped the top and reinforced it with 45 degree tubing between along side seats that made it awkward to climb in to get seated. Back end was customized to have something of a Corvette look and used large, round, Corvette tail lights. The car idled and accelerated ultra quiet and smooth. Owner characterized the car's feel and acceleration as reminding him of driving an Acura NSX.

 

All that said, I now want to see what you other Lexus swappers come up with. Send me some project photos for my engine swap feature if you want yours included. Please submit any photos to me at photos@zparts.com

 

Thanks,

Whoa steady up there SleekZ dont want you falling off any high horse.

 

I have that pic in my collection of info, many thanks, but one pic shows no more than that it can be done in LH drive as well as RH drive as we in Aus know.

 

Yes we need someone to provide more tech info.

 

On the issue of sumps, the later engines now available in half cuts have the forward sump, are other sumps available?

Because a 280zx has the rack behind the front cross member and clearance could be a problem.

I was going to get my front cut through Toyospares in Bayswater and the guys there have offered lots of help with any additional parts I may need,

has anyone else dealt with them?

Quadcamz what was the issue with the auto shifter, because that yellow GTO convertable runs the toyota 4 speed auto.

 

Someone has actually used one of these engines in an aeroplane.

 

Good to hear some Aussies in the forum. Neil

Found out a little bit of information about this swap,

 

The 1uz comes in front, rear & mid-mounted sumps, depending where you get them from, front cuts will set you back about $2200-$3000AUD,

 

The engine mounts are bang-smack in the middle of the 1uz block so unless you want the engine sitting right over the crossmember you would have to figure out something eles,

Like welding new mounts that come directly off the chassis rails so you can mount the engine as far back in the engine bay as you can get it,

Or,

Something like that bloke in the USA who is doing a 2jzgte conversion in a Zed, where he is welding in a brace from the crossmember back to the TC rods and the engine mounts sat in them, do a search on this site, there is pics of what he did,

 

As far as gearbox's go, lots of people do complete conversion kits to run the W58 type supra boxes or the R154 boxes, not to sure about the Getrag 6-speed though,

Dellow, Castlemaine Rod-Shop and there was a mob in NZ aswell, but i dont remember their name - if you do a search on google and localise it to Aust/Nz there should be lots of results - Dellow quoted me about $2500AUD for a complete kit minus the gearbox,

 

There was an importer in Melb who specialised in 1uz conversions and he said that he always used the stock factory ECU even when a manual transmission was used in conversions, he said he just modded the ECU, didnt really want to go into any more detail than that, so if you want to you could probably use the factory ECU if you ran a manual transmission
