I have had experience with not one,not two,but three of these damn things,and all of them performed the some way.It might of been just be bad luck,but im not ˟˟˟˟ing you when I say my 3.0 would run circles around that BLAZER.
By the time it was in need of another engine,lucky number three,I was hoping that the other two were just lemons,and if we just shoped around for a good quality rebuilt motor,that this thing would perform the way 4.3 litters should.
Well it didnt, it sucked just as much as the other two.Finaly my dad ˟˟˟˟ canned it,and got something else before this engine decided to die.

Anyone that dosnt believe me,can go buy an s10 blazer, "I dare you"

 

I'm gonna take a wild guess, but does the 3.0 maybe make 70 percent of the horsepower & torque that the 4.3 makes?

What are the specs?

Toyota 3.0 V6 3VZE - 150 HP, 180 ft-lbs of torque.

Chevy 4.3?

Also, the vehicle you guys were driving with the 4.3, what is it's curb weight in comparison to similarly equipped vehicles equipped with the 4.3?

 

I go to Spokane and back, so across the pass with hills and headwinds etc. with 396,000 mi on the truck and I don't have much if any problems I can easily stay at 75 the whole way with more speed readily at hand if I need it. Although it does take me 2 full tanks. and it does drink a little oil, and it is a PITA to work on but as long as its runnin fine...oh well

 

LOL, we have one. Its an 01, auto, 4.3 stock, and it runs like a scalded dog, and gets about 20 mpg on average.
You can see it in this pic.

 

I tell you folks. The 3.0 is a good motor. True it has it's problems and downfalls, but it's a solid unit. (No pun intended, LOL) I personally love my 3.0. It's not going to win any races, but it keeps going and going and going.

The Chevy 4.3 is a decent motor, but has it's share of problems, more so than the toyota 3.0. If you really want to drive a POS, then find a chevy with a 2.8 liter V6. Now that's a terrible motor.

If you think your 3.0 is faster than a 4.3, go race a Typhoon. Just dont bet any money....LOL

 

agreed on the 2.8 Complete Shiat

 

Now that's just comparing apples to oranges;I guess I'll compare my former 2.0 which smacked Vipers around.

 

yeah, thats compairing a properly designed engine that can handle boost to the headgasketless 3.0 yeah, the syclone and typhoon arent a fair comparison to hardly any truck, but the fact remains that since it's introduction in the s-series, the 4.3 has been a homerun in both power, and durability. the same can't be said for the 3.slow.

 

looking at the 4.3L specs:
90-91: 160hp, 230ft-lbs
92-93: 200hp, 260ft-lbs

for 90-91 at least the 3vze comes pretty close (minus the torque), similar weight between the 2 vehicles... guess depending on the gearing, the 3vze might come close?

mind you, im talking stock numbers only...

 

In this battle-ground state regular is $1.99 wherever I look, and its only tuesday. I found myself gazing longingly at a honda civic today....

 

Hmmm. Is that a 2wd? (important when you brag about mileage and performance) The 4x4s w/ the crappy 3.42 or whatever they are gears aren't any quicker than a good running 1st gen 3.0, btw.

 

the torque is what matters most though. also, a wide power band, where the 4.3 also wins.

 

crappy 3.42 gears, why so? the GM trucks are geared for power and economy in their powerband.

Have you any experience with a 4.3 S truck? If you did, I seriously doubt you would say it isnt any quicker than a 1st gen 3.0. :rofl:

 

I would!!!!!!!!!!!

 

I am an ASE Master Tech at a Chevy dealer. So yes, I drive a variety of them every day. There is one in my bay right now for an intake leak.

I also have an 88 3.0 4runner but it recently got 33s so it doesn't compare so favorably anymore.

And you never did answer my question about your 2wd blazer you are comparing to a real 4x4. I have only seen the wheels on your blazer on 2wds.

 

I think that one of the main problems with the 3vz is the PCV system. When people consistantly use high-wax content oils like Pennzoil, that ˟˟˟˟ collects in the motor EVERYWHERE and clogs everything up. Even recirculation of the PCV into the intake leaves a bunch of CRAP that chokes the motor out. After break in with valvoline, its all synthetic for me on the new block im building.

In addition, you have a poorly designed exhaust manifold and air intake system, not to mention the restrictive exhaust if your cat is a few years old. All of the bull˟˟˟˟ emission control vacuum lines need to go out - along with the EGR valve. The only vacuum lines you really need are for the fuel pressure regulator, brake booster and heater control valve..... The rest are getting capped...

The MOTOR really isnt a poor design. Its a very solid, reliable design. However, the complements to the motor could use some improvements.

The motor really isnt complicated to work on.

 

your observations about the 2wd wheels are correct, the wheel offset of the 2wd wheels would make them stick out about 3" or so on a 4wd.

Now, the curb weight of a 4wd over a 2wd isnt that much. About the weight of my cousin Bubba. Ill invite him along, and still ruin any stock 3L toyota.

I'm not 3.0 bashing here. I love my truck, but I'm just being honest. I've put alot of miles down in several S-10's, including towing some fairly heavy trailers, and I have alot of basis for comparison.

 

The 4wd adds a lot of drag too.............the 2wds seem a lot quicker to me. We will have to agree to disagree on this one. I think the 4.3 is a good motor, btw. I just think that when you add in the weight, trans and gearing advantages of a 1st gen 4runner, it does ok against the 4.3s in a 4x4. I wish I had run my 3.0 in the 1/4 mile before the 33s went on. Then we could compare.



3.0/ 4.3
150 hp/160 hp
180 ftlb/ 220 ftlb
4.10 gears/ 3.42 gears
3600lbs/ 3700-3900 lbs
usual trans 5 sp/ 4t60E AT

 

Well said I have had nothing but problems with mine, everything from a $1200 burnt valve to a massive oil leak, to a broken fan bracket and a bad knock sensor. I should have gotten the 3.4 instead. Besides it's so much more fun to go fast!
