a 1fz powertrain in a piggie? i know evan did that bitchen lexus v8, but has anyone done the venerable 6? i've got a line on a complete setup with trans and transfer, but am looking for ideas/help/whatever on a possible swap.
anyone done...

I too have been wondering what is involved there. The ECM can't be sent off to be reprogrammed? I know there are companies that do that type of work for the more popular muscle cars sportin late model fuel injected motors...What are the power/ economy specs of that motor?
w/numbers like that, I'll stay in the f family of engines
till I can swing a diesel

Gumby is doing this in an LV now and Gary did it in his 45, why would it need a PCM flash if you're keeping the entire drivetrain? Should be just like a 3FE swap, you need the ECM and complete engine harness plus a few connections out of the body harness. You will have to marry the scaled down harness, but it's not really a big deal.

Gary did a body transplant. I'm doing a 1FZ/A343 swap into a 45LV body. Some stuff is the same.
Gauges and speedo are going to be interesting. Most of the other body stuff won't need to interact with the engine and trans. You'll need the inside and outside harness though. I don't know why Toyota put the CDL relay clear on the driver side kick panel, but they did.
The motor fits really nice, but it's a bit long. I had to open up the firewall a little for the bellhousing and the floor for the bigger transfer case. I'm not sure what I'll end up doing with the radiator and fan, but it won't be that hard. The axle clears the pan fine on the 45. It'd be worth taking some measurements off the marshmallow. The 55 axle sits back further than the 45 I think.
You gotta do it, 'cause nobody else has yet. It looks and feels right. Even more than a 4.7 iForce pig.
I wish I could get going on my 45 to stay ahead of you and help you out, but it's not looking good for getting moving on mine soon. I've gotta get the tow rig and wheelin rig back on the road first.

I was quoted $20k I think for the 5.7L from the dealer!
I'm not familiar with either 3FE or 1fz. But a lot of vehicles have gone to incorporating security features into the PCM(ex: GM's VATs system) The GM system is not a simple "12v source security" but a signal generator type deal(key resistance feeds a "security" box that feeds the PCM)
Just to put some comparison numbers:
2F - 125hp, 200ft-lbs
3f-efi - 155hp, 220ft-lbs
I've gotten to ride around an FJ60 and FJ62. Both seemed a little anemic
I'd love to see a Tunda 5.7L swap... THAT has to be a fun rideOf course, all the measurements I saw said big block Chevy sized
I considered it briefly over my 6.0L Vortec... but the 2x+ price tag was a bit bad
5.7, like the 4.0 V-6 is intricately tied into all kinds of systems you probably don't want to have to deal with, like wheel speed sensors and yaw sensors. Unless you could go stand alone aftermarket ECM, they look to be a ton of trouble.
But then I'm sure people used to say the same thing about TBI.
If the 1FZ security system is tied into the ECM, I'm sure it can be disabled. I really don't think it is.
Small blocks are easy, cheap power. Every time someone talks about building a 2F for power I always argue against it. There's too much work and cost for too little gain. The 1FZ is a great motor. All the sins of the 2F that can be fixed are. The ones that remain, the size and weight, are an easy justification for the rightness of the engine. Yes, a LT1 engine can make way more power, but how much power do you need in a pig?

i had a v8 40 and yeah, it was fun but it was also a hassle, mainly because of carburation.
this all evolved because on the 71 pig (which is setup for a sb chevy for financial reason....i had an extra v8 and adapter, and the pig had no powertrain) one bellhousing bolt is broken off in the block and no matter what i try, it refuses to come out. i'm at the point of pulling the motor so i can fully weld it up, drill and tap it again.
then, what do i find for sale? an lt1/marks adapter/full howell setup witn 4spd cruiser trans/tcase from a 77 pig. and i just so happen to have a large chunk of change from the insurance company for a bunch of stuff that was stolen that i really don't care to replace. while discussing this with a friend, he tells me that for half the price, he'll sell my his 94 fz setup with harness, trans, transfer and driveshafts.
so i start thinking....i'm happy with the 1fz in my 80, which is about 1000lbs heavier than a pig. it gets decent mileage, is pretty much trouble free, and it's toyota. plus, since i have an 80 also, and no other v8s any more, it cuts down on extra parts stash stuff.
i'll have to look into the security system. i don't know if it's tied into the ecm...it is tied into the ignition somehow because i've ried to remove the brain and the marshmallow won't start without it.
todd, how much clearancing did you have to do on the 45? that could be an issue, since squeezing a v8 into the pig required reconfiguring the ebrake setup on the pig and it fit into a 40 series engine bay with a ton of room to spare.

Nuclearlemon,
What do you think about the fulltime 4 wheel drive? Is that a pro or con for you? I love the idea of an all toyota pig, but sometimes the cost can be outweighed by the benefit depending on your use. I know if I would have really sat down and more clearly laid out my intended plans for use on my 55 I would have ended up in a much different place then I did once the ball started rolling.

I'm going with a 3FE in my 40 mainly for the fuel injection, it has a little more HP and a little more friendly power curve for the highway ... but it's still a tractor motor. The a440f is the main culprit behind the lack of power in a 62, the 3FE is pretty peppy with a H42/H55 behind it.
The I6 vs V8 debate can go on forever, the are just really different engines that make power and torque differently. I think the 1FZ is fine in my 80, I don't think a cruiser should be a race truck either. It would be a good upgrade in a 55 if you were inclined to do it IMO. These came in trucks that are old enough that the electronics are not really an issue (actually not until the VVTI engines for Toyota).
Do what you like, be happy with what you did

BTW: I think your Vortec is sweet as well ... as would a 5.7 Toyota.

both. great traction, but no more spinning donuts
won't be an issue with the pig since it will still be on 60 series axles and for mileage/breakage reasons will be going away on the 80, then i'll let ya know when i can compare a part time 80 to a full time 80. fwiw, a lot of the 80 part timers say they love the part time
there would actually be a significant cost savings going toyota...the toyota setup is almost 1k less than the lt1
There is an initial cost savings of $1k, but you have a lot of labor to redo all of your motor mounts, trans mounts, wiring, etc. If you are doing all of the work then it is a non issue, but if you have a shop do it, that will be gone in no time. Not to mention everyone one works on SBC while the Toyota motor will be a little harder to support depending on where you are/live. I am not trying to dissuade you, I really like the inline 6 motor, I am just asking the questions that I didn't ask myself when I did mine.
Yes you can run a part time kit, but that will also eat into that $1k advantage the Toyota sees up front.

A couple of inches up the firewall, but I don't know how much that was needed. It's an easy fab for more room behind the engine though.
I cut the floor out straight back from the widest point of the trans cover all the way back to behind the transfer case, but the case is tucked up tight to the rear crossmember for maximum ground clearance.
I really hadn't looked in the 45 for a few months. I have to get it back in the heated shop. The garage is just not keeping it dry enough.

I liked the AWD in the 80. I think I'll like it even more in a vehicle that I'm not going to be out power sliding. If I don't like it, then a CDL switch and lock out hubs is easy enough.
I liked the power in the 80 just fine too. If I get bored with that I'll get a supercharger for it.
I'm also interested in finding out the mounting differences between a A340 and a A343. If it's the same or could be made the same there's no reason why 4runner case can't fit, and if that's the case then there's a ton of gearing and doubler options as well as part time options.
Not that I'm interested in doing that to the LV, but I can see myself doing this swap again in the little pig or a 45LWB

I think you've already got a line wanting to buy that lv, cool conversion for sure. I thought the 4Runner transfer dropped on the wrong side?
