it helps to make it breathe better

the engine may be under-powered but that's what helps with it's longevity. the small displacement.

3vze's are definitely a love-hate thing

just my 2⊄

I have 3 rigs with the 3vze... and i can say, i think most of the fuel economy issues r with the auto... my auto has always got 17mpg avg... and i have had it for over 175k miles.... my 2 5spds however get over 20mpg... the runner gets about 21 w 31" tires..... and my p/u gets between 20-25 w 33's depending how i drive it, and where...highway gets me close to 28 mpg... in town closer to 14....

Bahhhhhh. I still dont like em. 22r FTW.

I have a 90 runner 3vze with 273,000 on it. The thing gets terrible milage and its very weak! I live in the mountains of NC though. This is just my personal experience, no flamming please. As soon as finances are availavle it will have the 1uzfe installed. Cant understand why toyota didnt put this in from the factory. The 4runner is alot heavier than the sc 400. Would have been an awsome option!

The 3.0 can never be more than it is...

If you want more mileage, then swap in a 3Rz...

If you want power, then swap in a 3.4.

rebuilding a 3.0 for economy/power?

End of story.

UH..no it wasn't! The 3 in 3VZ-E stands for 3rd iteration or 3rd generation or 3rd version(whichever suits your fancy, as they all mean essentially the same thing). So it would actually be the 3rd in the line of the VZ series V6 engines by Toyota. The original V6, that all later versions in the VZ series V6's that would follow it were based on improvements to the design of, was the 1VZ-FE. Those improvements were made for the purposes of adding overall performance in the later iterations. There was continual progression in this manner, one step at a time, all the way through the production of the last engine in the VZ series, the 5VZ-FE.

1st: 1VZ-FE
2nd: 2VZ-FE
3rd: 3VZ-E
4th: 3VZ-FE
5th: 4VZ-FE
6th: 5VZ-FE

Listen to him. He's right on the money.

I can add to it by noting that the 22R-E has most of the same issues as the 22R and even more due to the increased power output(post-85) without any significant strength increases in the engines components to handle it. The 22R-E is also just as prone, if not more so, to head gasket failures as the 3VZ-E.

The 3VZ-E is not a "bad" engine. Most of those who claim so have never owned or driven a vehicle with one. Those that have must not have ever driven a vehicle with the 22R(E). Their comparison performance wise is staggering. Or stated more correctly, there is no comparison. The 22R(E) is not even in the same ballpark.

What's more? The 3VZ-FE is considered by some to be the best V6 Toyota has made to date. Even better than the 5VZ-FE or any of the MZ's or GR's, because of it's comparable strength and the ease for which performance enhancements can be achieved. No OBD-II to deal with and after-market upgrades to it are alot cheaper than those for any of the later production V6's.

PS: I've worked on my sister's 98 Eclipse so I can vouche for that statement being true as well.

Oh, and the term your searching for is "bank-fired injection" vs. "sequential-fire injection". The difference being all the injectors are simultaneously fired for one side(all 3) and then the other side(all 3) of the engine on a bank-fired injection system. As opposed to each individual injector being fired one-at-a-time for a sequential-fired injection system.

The claim that the 3VZ-E once, or at any time during it's production, was equipped with a bank-fired injection system IS AN INTERNET MYTH. TOYOTA HAS NEVER USED BANK-FIRED INJECTION SYSTEMS!!!

this should go in the "dumbest thing someone has told you about cars" thread

I stand by my turd statement. Worst ever toyota engine.
The guy asked what we thought....not for us to jump on each other and try and be internet genius's. Asked for opinion. I gave it. I own it. Its mine.
Your opinion is yours. You own that. Dont attack my statements...make your own.

MudHippy

You go right ahead and do that friend.

But first...Why don't you try counting the number of 22R(E) blown headgasket threads on this site first. Then subtract that number from the number of 3VZ-E blown headgasket threads.

THEN see what kind of statistics you can generate from it!

Don't be too suprised to find out whose the "dummy"!!!

tried4x2signN

I'm sorry, but a 22R is nowhere near the 3.0 in head gasket territory.

Again, back to how vehicles are treated...

About 90+ % of the 22R repeat head gasket customers I've heard of, can be traced back to terrable machine shop work, or none at all.

Ppl just ran them till they couldnt anymore, then expected $20 head work, or none at all, to hold.


Whereas the 3.0 was inevitable. Plus, the 22R didnt have materials change, a close to the head exhaust pipe (#5) design, and a reduction of head bolt size like the 3.0 did.

MudHippy

What exactly does that mean?

How was I attacking your statements?

The statement you made was incorrect and I corrected that. That's called teaching and learning and should be appreciated for what it is. I'm not always fortunate enough to be the teacher, and frequently learn things from others on this site as well. I accept such teachings in a grateful and respectful manner, as I would expect from others. And, BTW, that's what the quote button is there for.

Furthermore...Just because I am an "internet genius", doesn't exactly give you the right to hate me for it either. But go right ahead...if you must.

TOYOTA 1

whoaa, idle down chainsaw.. i was just messing around..

do i have your permission?


for giggles i just typed in "22r blown head gasket" and got around 70 threads pertaining those words. then i searched "3.0 blown head gasket" and got around 170..

last i checked the 22r never had a recall for hg issues.

to each there own

yotaman85

maybe not inevitable, but most likely. i have seen a bit of factory 3vze HG failures and have seen relatively few from the 22re. this is not an internet search statement, this is from real life experience. tried4x2signN is correct about people just slapping the 22r(e) back together thinking its bullet proof. this just equals fail...

MudHippy

Really?

I searched the terms 22RE blown head gasket and got 191 threads.

Then searched the terms 3VZE blown head gasket and got 90 threads.

Nice try though!

Are we through here?

TOYOTA 1

wow tough guy.. why such the attitude??
try searching 22r blown head gasket, then 3.0 blown head gasket.

i see that your taking this a lil to personally, so ill just leave it at that.

i apologize for striking a nerve, i didn't mean to.

BackGateYota92

haha another toyota owner vs toyota owner thread. lol cant we all just agree that every motor toyota ever made is amazing?!?! lmao jk

94toyota

thanks for clarifying that for him before i had to mudhippy

JDS1992

wow i get about 16-18 but i mostly am driving in town, about 90% of the time..and I have pretty small tires right now, the ones i bought it with, they're 235/75/R15's how big of I tire can I get with just stock ( no lift)? I heard I could get 30x10.50 but idk Its on my 92 4Runner SR5, my 99 has 265/70/R16's on it ( limited edition)

JDS1992

Thanks for the feedback, I appreciate it, from What you guys have told me Im more confident in my Engine..I treat it pretty well..I dnt stomp on the gas everytime im stopped and leaving an intersection...I shift around 2700-3000 RPMs..I think I treat it pretty nicely..I run Plus Fuel in it and I put Injector cleaner in pretty much after every oil change..

MudHippy

tc's got 33x10.5's on his 2nd gen. 93 4Runner with no lift.

Oh, sure thing, though I probably didn't give ya exactly the advice you were asking for. I'll try and answer any questions I can for ya in the future.
