Has anyone ever done a lab analysis on the 3vze head bolts to see if that is a contributing factor to our headgasket failure problem?

 

I have wondered the same thing.

Just to clarify, the headbolts themselves are fine--the problem was Toyota didn't torque them down enough for the bolt to stretch and properly clamp the HG. I bought my Supra with a blown headgasket and one of the headbolts was so loose I could have removed it by hand!

I know everyone is gung ho about the supra swaps, but about swapping in another 6 cylinder into a second gen. i.e. the 3vz-fe or 1mz-fe. The 3vzfe may almost bolt directly in and has 50hp to boot. Just some thoughts I wanted to put out there.

 

I would be interested in a kit for 1st gens.

So will the 2JZ-GE engine bolt onto the W56 tranny with a N/A Super 7GTME bellhousing?

 

No, you need the 2JZGE bellhousing, and you can bolt up your W56.

And about swapping a 3VZFE, isn't that the piece of crap 3.0? I yanked that pile of crap out of my truck at 70,000 miles. What a waste of a motor. Don't even think about that swap...I forget engine codes sometime, what is the 3.4? That is a good motor.

Reasons to swap on a 7MGTE

Cheaper than most other swaps
Much more power than most other swaps 300hp and 300ft/lbs of torque with easy to get 450hp and 450 ft/lbs of torque.
Extreamly hight and flat torque curve which makes it killer for acceleration, will surpass any V8 running similar power.

 

Wow i didn't realize it was that much of a power increase. I should pay more attention to this thread. I didn't even realize the runner could handle that kind of power.

 

Well, the runner really can't, but it is on all how you drive it.

The only thing I havn't broken is the T-cases. Everything else I have blown up, inluding my Dana 60 rear 6 times over.

My R151F I acutally only broke a shifter fork, that had nothing to do with power.

 

SuperRunner so I guess the question is. How much HP and Torque can the drivetrain on a 4runner take? For instance a 2nd gen. that has the 3.0 with the 5 speed??

 

Well, to use that tranny, you would have to make a custom bellhousing, but the tranny can handle 400+, your rear can handle around 350 unless you abuse the clutch and break everything by revving it up to 4000rpm and dropping the clutch. Which is what I do on a daily basis almost.

 

Yeah i hit high rpms on my current engine. I can't imagine adding that power and not wanting to fully take advantage of it... What can we do so that we don't have to worry about that? I can imagine it's a good amount of parts and a few modifications.

 

wow, Sherrigirl came back, temporarily at least.

 

Can someone answer me how the 2JZGE is better than the 5VZE as far as practicality goes, aside from the fact that one is a V6, the other is a I6 that was never meant to go into a truck.

On a side note, will the 4.5 I6 Landcruiser engine fit into a 4Runner/Pickup?

I have 190,000 miles on my truck, and whenever the engine goes (knock on wood) I plan to get a 5VZE (non SC) just because it seems to be a lot more practical and has been done many times, and as far as I know it's not much more than a 3VZE, and it's been in the 4Runner/Tacoma for 8+ years now.

The 2JZ sounds cool, just a bit impractical because it's such a new idea. Whoever does it though gets a lot of respect from me.

 

updates?

 

the kit sounds like a good idea, but i am gonna swap in the LCengineering 2.6 22re. I just like the little guy to much to try something else.

 

Are you serious? I've got a MK IV Supra w/ a 2JZ that dynos over 600 rwhp... and that's not even breathing on it hard. I can point you to SEVERAL (actually a few hundred) 93-97 Supra owners making 500-1000hp on PUMP GAS. That said, I know that too much hp and torque are bad, but I don't subscribe to the theory that you can have too much of either. You've got control of all that... it's called your right foot and common sense.

I've got a LC and a 4Runner... just by looking at it, NO. It won't fit. Maybe w/ a BFH and some cutting, but it certainly won't just drop in...

A motor is a motor is a motor... doens't matter what kind... just takes a little bit of inginuity.

 

Inline 6s are the best engine design IMO. There are a lot of reasons to go I6. They do not necessarily make less torque than a V6 OR a V8, especially at varying RPMS. Just because a V8 makes lots of torque low in the RPM band doesn't mean it's better than an I6 with slightly less torque (but spread through the whole band)

Inline sixes are:

1) the smoothest and most balanced engine design (okay I think V12s (two I6s at an angle, right?) and another funky one are just as balanced, but they are much less common)
2) make lots of torque low in the rpm band, so they aren't necessarily just for cars, remember the Supra is freaking HEAVY for a sports car.
3) very reliable (even 7mgtes, after you fix the headgasket bolt issues)
4) get as good mileage as anything else

 

I was going to pronounce the rotary as the smoothest running engine, but then I read this...

I guess my trusty ole' Wankel in my 3rd gen falls into the catagory of " funky ".

 

ok so who is doing the 22re/3vze to a wankel engine swap?

Seriously though, any updates?
