Attempting the next best engine swap for 80s IMO (8 Viewers)

My post above was meant to shed some light over the low RPM torque while being off road.
In low range and first gear the RPM won't stay low on any type of engine.
If one wants to take advantage of a 40:1 (or better) gear ratio, it will only happen while in first gear. Once you go to second or third that ratio will quickly drop.
I have to disagree. With enough torque you pick the a gear low range first gear or whatever and let it idle over the obstacle.
 
When you say these engine transmissions are priced reasonably and readily available, what price are they selling for?
 
$5-6K US equates to way more in Canada.

So for you Americans with your large population that’s reasonable.

I’d say in Canada you would be lucky to get it for $10K because of our smaller population. Then there are adapters required and other stuff so probably $15K Cdn in parts.

Lots of gasoline for my 1FZ.

I can understand the appeal for you now🍻

Drive it to US, have the swap done here, drive it home.
 
If these engines and transmissions are rock solid bulletproof without any problems- As we all know all new GM stuff is always perfect (no class action lawsuits or anything like that lol)- I'm sure the price of these will stay very low for a long time to come.

They are already on 2.0
 
This 3.0 LM2 makes 500lbs of torque at 1500rpm. That’s what is so nice about it compared to gas engines. With the LT1 I took out needs around 4500rpm to match the torque numbers. Which will probably never be seen on slow speed trails. Baja maybe a different story

Did some googling on the LM2, sounds interesting for sure.
95% of peak torque is available from 1250rpm.
Long (ish) stroke I6 is gonna produce more usable torque than a short stroke V6
Common rail injection changes things too. Super high injection pressure!
Solenoid injectors capable of 10 injections per combustion cycle is cool

Torque curve is pretty flat, then drops off a bit of a cliff after 3500 ish rpm. Gives you usable 2000rpm spread of torque off road, more than enough to get moving and shift up a gear, or hold the gear you're in

That's why the 10 speed tranny is a good match to keep the RPMs low in the usable powerband.

Nope, I do all my own work!

Exchange rate is 30+ cents on the dollar. Not feasible. Secondly I would be dinged for GST and duty taxes at the Cdn boarder.
 
With regard to the gearing, I suspect with a much wider range over the ten speeds, these would really shine offroad with 3.1:1 transfer case gears. Get that first gear down to around 60:1 and you've got a really usable range all the way up through the higher overdrive gears.

According to your signature, your 1FZ is getting up there in miles. Many need a full $$$$ rebuild about 350K miles.

I think the question is, when your 1FZ needs a rebuild, what do you do? Spend $$$$ to rebuild it or do you swap in a more modern motor? I personally think the 1FZ-FE is a s*** motor...there I said it. 😁

I know what my answer was when I had to make the choice: L96/6L90e. IMHO, the best engine/trans combo one could swap into a 80 series. IMHO, the 80 series is begging for a V8.

I don't disagree with what many have posted about the LM2: Timing Chain, Oil Pump Belt, Limited Production Run and the questions of overall longevity and reliability.

To be fair, are we putting another 200K miles on these vehicles? Probably not...My LX450 is not my daily...

So, in hopes of nudging this back in a tech direction and out of the gutter of comparative politics and the equally pointless brand oneupsmanship...

@Drewthecarguy
I'm curious about a few other odds and ends. Maybe they got mentioned and I missed it, or maybe you haven't tackled them yet.,,

Cruise control? Is that being handled via the LM2 engine management, or are you using the Toyota actuator? Using the stock controls, or something different? Or is it not addressed yet?

AC? Same sort of questions, i.e. is it working, and if so did you use Toyota or GM parts and if so, which and in what combination?

heck yea some questions instead of opinions lol

Cruise control is doable. I don’t think the factory stalk will work, but swaptime makes a cruise control module with buttons you can mount on your dash or center console. What I am going to try to do is buy a modern Toyota steering wheel (2020 Camry to be exact) and use Trailteq’s adapter (whenever he can ship to the United States) I’ve already been in contact with him about it. And I want to use the radio controls and cruise control on it. I think that would be awesome

AC is easy, GM compressor everything else Toyota. I had it running in the LT1 and it was great. I just got to finish making the hoses. I’ll probably get that done next week or so
