^Good engine - too old - overrated - good engine, but so overrated it's as much a joke as a good engine.

That enough?

82-83 5MGE's had the dual v-belt drives. 1984-on 5MGE's and 7MGE's have the serpentine belt drive. I've had both. The 82 5MGE's had the lowest compression ratio, making them the friendliest to turbocharge. Check out www.celicasupra.com for more info on the 5MGE and 3liter 6MGE!

The 5VZ-FE is overrated? Just curious why you think that after saying this:

"The 5vz-fe was the next logical step for trucks. Combine proven Yamaha design heads, the VZ block family & new OBD-II mandated electronics/emessions packages."

Bumpin' Yota

He's right.

At least on this site from hearing people talk you'd swear it was better than the son of god engine, the LS1...

Sure the 5vzfe is better than the 3vze but I believe that is ONLY the case due to the heads...

You get a company to comeout with some 24v turn key heads, MLS HG's, and some aggressive cams and I think people's mouths would be on the floor...

5vz-fe - good engine
7m-gte - too old
1jz-gte - overrated
2jz-gte - good engine, but so overrated it's as much a joke as a good engine.





You misread.

Go with the 5M over the 7M any day. It has bigger valves which handles boost better than the 7M-GTE.

Toysrme

Ya. I mean 7m-gte's are good engines, not to take away from them. They can handle 400 easy, but... I have to ask the question, why seek out an 18-20 year old engine, when you can just buy something with less wear one it.

Then again you can completely rebuild a 7m-gte for the same money as a jz-gte & have a practically new engine.


Orrrrr buy an 89-95 1uz-fe used for like $500-1000.

It's hard to complain about any of the engines you mentioned. Anyone would be hardpressed to tell me that my forged-internal'd and metal headgasketed 7M-GTE isn't a bulletproof engine at just about any power level. 2JZ-GTE handles even more power but the cost of obtaining these engines puts them pretty far down the list when it comes to cost/benefit ratio. I have driven many 2.5L 1JZ-GTE twin turbos--what an awesome motor, but 2.5L is a bit small for any truck application. The 5VZ-FE seems to be very dependable, makes decent power and gets pretty good mileage, internals seem strong enough to support larger power goals in the future. 1UZ is very affordable and makes good power out of the box. If I had an older 4Runner, I would have a difficult time deciding which engine option to pick.

Now I'm finding myself wanting a Toyota Epic boat with a factory 1UZ.

7mgte is one of the most under rated motor's form toyota

there the cheepest motor to get power out of period i whould know i have bena playing wiht them for years

500 is joke in the 7mgte world now

only down fall to the motor is the head it can't flow to what the 2jz does
7m has more turq as well

teh 5m/6m is umm really old and umm junk motor's the 7m is just better

Tsoock

How hard is it to change the valve seals without pulling the head on the 5VZ-FE? I'm burning oil lots of oil on startup with my 2002 Tacoma and would like to self-repair, if feasible. How difficult might this be for someone with some mechanical experience? Or should I have a shop perform the deed?

So, as a late reader to the discussion, my apologies. The benefit of dropping in a 92-93 Camry XLE engine over a 5vzfe conversion would be not needing all the extra fuel system conversion parts? And does the 3vzfe have that same cold start injector? Otherwise I'm leaning to the new idea of just switching to an FE 3.0

You wouldn't consider cutting the intake manifold right at the mounting flange and re-welding it 180° for the throttle body to be in the front with an electric fan conv.?

KistCustoms

I know... I'm new to yotatech. But its something we've been considering. Just tryin to get opinions from more VZ experienced owners

MudHippy

It's not that it couldn't be done...in theory. It's that there's SO many reasons why it's the most extremely impractical swap imaginable. Which is why it's 2013 already...and NOBODY has managed to swap a 3VZ-FE into a PU or 4Runner(or any RWD/4WD vehicle). Trust me...the further you research the subject...the more you'll realize how totally impossible it is, and why it's pretty much a dead-end street. I even gave up the notion of just swapping FE heads onto my 3VZ-E years ago...simply not feasible.

FYI, the throttle body being in the wrong spot is the least of your concerns.

BTW, the engine in my avatar(400HP 3VZ-E built by TRD for Ivan Stewart to race in Baja) is the ONLY 3VZ-E to EVER have twin-cam heads. And they were one-off castings(never to be duplicated). So that can be done for sure...but for more money than you'd ever want to imagine.

KistCustoms

I don't mean to sound nieve, or hung-up on a dipstick idea, that hasn't been built for clear reasons. I just devour any info I can get a hold of. but isn't the block exactly the same? (i know the crank is forged in FE) but it really seems like just that throttle body/intake manifold is the only problem. Otherwise an engine, computer, harness swap? What else can get in the way besides maybe the steering shaft? don't wanna annoy, just very curious

HighLux

Its a bad idea. That engine is designed for a fwd car. Is this all because you have one on hand? If so...sell it and get the proper one.

You will not be breaking new ground and starting a trend. You will be the only one stubborn enough to do it, no one will follow suit.

You are forcing a square peg in a round hole.

KistCustoms

I do get what you're saying. Like I said, don't mean to waste post space with a dumb idea. No, I don't have anything on hand except a 2nd gen that needs the heads rebuilt. I just try to keep as similar a motor that came in the vehicle as possible. (like, I hate Mustangs with Sm block chevys) Obviously if there is a potential to convert a sohc to dohc, I want all info and opinions. Point taken though, I see you all over the boards and trust your experience. But come on, whats the first thing you wanna do when someone says "impossible"

ThatGuy1295

I could be way off here. But somebody should mention that truck motors are usually designed to move heavier vehicle's without consuming as much fuel as fast little race cars would if they weighed 5,000lbs. And to stay on topic, im sure the 3VZ-E would consume less fuel while towing anything then the 3VZ-FE would. Or we would all have gone V8 along time ago. But mostly im sure the mpg difference would be large between the 3VZ-FE and 5VZ-FE while doing any kind of towing, even without a supercharger. And towing/hauling is a factor since we are talking about trucks here. More ponies doesnt mean much in the pulling/mpg world. More like torque and economy. Or at least thats what I always thought.
