I've got an opportunity to purchase a 1fz-fe driveline (complete with all electrics) and swap it into my 66'FJ45LV project. Having never had the opportunity to actually drive a '80 personally, how much more umph is this gonna provide? Is it worth the time/effort/and $$? I know the 2F isn't that great with a 3spd, but it is nice to be vintage.

I'm going to use the 2F (originally planned for the LV) into my '74-FJ40, and this left me with an open engine bay for the FJ45LV....figured a full-time 4WD LV wagon would be pretty cool!

Any known hiccups with the 1FZ-FE drivetrain?? I know that the electrics will be a fun challenge, and I think the ECU will fit nicely under the dash.

I've considered finding a 80-series thats been trashed around and just throwing the LV body on the chassis of the 80. This would give a very nice suspension under the LV, but it would cost nicely!

I think the driveline of the 1FZ-FE would fit nicely under the body of the LV, with a similar wheelbase. Does this d-line have a full-time 4wd on it?

I'm also looking into options to incorporate the original 3-on the tree style shifting.....more on that later :)

Some details/personal opinions about this drivetrain would be helpful!
 
If you want raw speed, put a 350 in your LV. 80s are powerful, but are not a rocketship. There are big issues about fitting the 80 series guts into your frame, and if you use the 80 axles, they'll be quite a bit wider than you might like. So, don't think of this as a small project.

Someone at the Rally in Denver had a 45 LPB body sitting on an '80 frame - I'm sure some lister knows who that is. Might be worth seeing/driving that rig.
 
search for Waggoneer's thread in the hardcore section for the 45 lpf on the 80 drive train and frame. Also Mikesta is 'slowly' in the process of putting an lv body , with some modifications onto an 80 frame and drive train.
as cool as it would be I would hate to do all the work. I have an 87'2f in my lv and am having to solve issues with getting it to fit and work luckily others have done this before so I am able to use what they learned like which motor mounts. you will need alot more than just the engine. I am doing the fuel lines and tank stuff right now and am having to add a return line into my tank but am thanking God I did not go with a fuel injected engine and have to deal with a fuel pump in the tank and all the pressure isues that would come with it. if you could grab the tank too that would help.
Again it would be cool but as said before the v8 would be far easier and cheaper.

My plans were for the engine/trans/xfer from the 80 series, and the axles originally from the LV. I can see that the fuel system could be a challenge.

I'll check around for Wagoneer

I am thinking about this very same thing. I bought 93 that had been rolled
and it still running and is drivable. It also has lockers a plus. I have a 45 short
bed truck or 45 wagon just sitting around waiting to be built. So many projects
and not enough time.
Keep us posted on how this works out for you.
 
I saw your post on my thread, I have a drivetrain in my FZJ45LV donor up for grabs.
 
I've seen Waggoneer's truck (pictures only) quite the buildup!! A little bit more intense than I'd like to go! I will keep the LV frame...and drop in the motor/trans/xfer along with all of the accessorials needed for the 1FZE motor.

Mikesta, you have a PM
 
Nuke-

Haven't heard from you or Mike D. in quite some time!! Hope you're doing well! Guess its been since the 'snow-run' with my tacoma....shouldn't get so stuck this year!! :)
 
I think the 1FZ drive train would be cool and should have plenty of power. My trucks runs really good and not short of breath. The electronics and harness are very simple. Lots of wires, but after you weed out all the caca, its pretty basic stuff. I don't think you will be disappointed. I am thinking of doing the same thing in my 83 FJ40.
 
Gary-

Having never seen an 1FZE up close, to do the measurments, where are the placements of the engine mounts?? I'm assuming with that massive trans there is a cross-member supporting the weight.
 
Does anyone have any other suggestions BESIDES SBC 350 in the LV?

I've decided to build it for comfort and driveability rather than purist. Pure/factory is great, but just not driveable on a daily basis.

iForce V8? 3.4l Tacoma (S/C'd of course) FJCruiser drive?
 
Like I mentioned elsewhere... Diesel. A toyota diesel (like a 1HZ, 1HD, etc...) would be awesome. I'd bet an LV with a 6 cylinder turbo diesel would get 25 mpg or more, and the benefits of a diesel engine are many. Especially when it is a Toyota diesel.

If you haven't driven a Toyota diesel, you just haven't yet experienced how well they operate. I really think an LV with a diesel would simply kick butt. If you could get a diesel 80 series drivetrain, then all the better...

Cons are: cost, and rarity of parts. If I need much more than an oil filter, I'm probably going to Australia for it.

Pros are: you can burn bio, torque like nobody's business, they're super cool, and no ignition system at all. They're also fantastic for crawling, as they will idle all day long at low RPM without stalling.

I am a huge diesel fan myself but my 61 with a 12HT only gets about 17 combined MPG, which makes it barely better than a gas engine as far as fuel economy goes. The parts are easier to find obviously with this combo because as long as I can get my parts guy a part number, he can get the part.
The 350 is an easy swap, decent MPG and parts availability is great, but this combo doesn't have the cool factor to me as everyone has done it.
The 1FZ's issue while in the 80 chassis, is where Toyota placed the drivetrain. It is moved very far forward making a front radiator install difficult to say the least. If you moved everything back, you could make it work.
I like the all Toyota conversion, so if it were me, I would do an iforce drivetrain from a Tundra. All Toyota, so it has the cool factor, and the shorter V8 will fit with a a radiator in the stock position.
 
I think I'll stay gasoline on this build. Thanks though :) I have only driven Freightliners and Volvo diesels.... tractor/trailers that is :) I love diesels for their torque and longevity, but just not in this LV. I'll certainly consider it for my troopie buildup when I'm done with this though!

I'll definately be staying with the LV's frame and axles, as I've already restored them! (pics attached) I love the iForce V8 idea....just costly getting one for starters!!

The 3.4L 5VZFE does have plenty of power when supercharged...as on my 02 Taco. Really like the smaller size of that one, along with a double-cab taco's automatic trans.

A major kicker is the location of the differential in the LV rear. Being off-set, a newer Toyota x-fer is centered...This isn't going to be a rock-crawler...just a daily driver for my wifie :) No dual-xfers going under here ;)

Take my input with a grain of salt, but I like the 1FZ-FE! I totally agree with the sentiment of staying toyota, but I like to go one further & always try to stay with Landcruiser parts. Just because I always feel like they were designed to work with the weight, etc... Landcruisers.
I especially like the idea of the 1FZ if you can get ahold of a supercharger or trubo kit to stick on it. Then you have a super cool drivetrain, that has even more power that stock 80's, but also is built for the abuse that Cruisers are made for...

Not sure what to do about the centered transfer. I never got that far into the planning on mine. I wonder what the other people that have done this sort of swap did? Perhaps the H151 5 speeds from OZ are set up with the off-center diff in mind...
 
Abe, I certainly agree with the all-cruiser stuff! Thats the major consideration when you brought this to mind.

I've never driven an 80 series truck, so I can't compare the power they have. I bet the 80 weighs close to the 45LV.

Again, any idea on the 'full-time' 4wd issue? I don't want to be spinning the front drive while I'm on the highway! That kills fuel-mileage. I'm sure there is a way to disengage that feature of the stock 80 drivetrain.

Anyone know the trans/xfer case numbers/type on the 1FZE?
 
I went with Ram Jet 350 crate matched to a H55 trans, this is in a FJ55 and this puppy is fricking fast and can cruise all day at 75. It's pricey but in the end I could not see spending all the money for other mods and have a truck that could not get out of its own way. The Ram Jet has three wires to connect, carries a palm size computer mounted on top of the motor. Here's a little teaser for ya: Check out this video link!
