10 most bulletproof motors ever made, ever. Not necessarily in order

The 4.3's are better in pretty much every way except for the spider injectors. There's way more 4.3 astro's and safari's left than grand am's. with 3800's.

Redblock reporting in, B230FK. Bulletproof.

Vote for the 4.3
Still blurst in class

>lists B series but not the superior K series engines
Are you even trying?

5vzfe

The lima 2.3. I have 3 in my driveway and theyre all over 350k

i had a 22R Toyota Hilux, just sold it this morning actually. nice truck but holy fuck i had issues with that engine. first and last carb vehicle i'll own

>carburated engines
Surely you can find alot more bulletproof engines than those.
>What are Toyota diesel engines?
Most bulletproof engine i know is the 3B.
Also Mercedes had alot more god tier diesels during the 80's- 90's

To be honest, I don't get the hype around the K-series engines. They seem so un-Honda like.

didn't grand ams only come in 3.4L ?

>10 most bulletproof motors ever made
>list includes american engines
pick one

Cummins 6BT (5.9 12v)
1UZ-FE
N54 (for making big power on stock block/internals etc, not for reliability)

Carb > efi for longevity

You forgot the M30 and Redblock.

Also a few of those you listed have issues that crop up over time that could potentially kill them.

Longevity? You mean they are all mechanical, but carbs never work as they should, they are too unreliable.

You leave a carbed engine to sit for more than year, and try to start that bitch back up.

Then do the same with EFI.

Now tell me which will start immediately.

they are even sensible to air pressure

ayy

They got a sexy tone to them.

>tfw 3sgte
am i invited

just drain the gas before you let it sit,

Yeah. Had to pick 10. 3stge is notably less reliable than 3sge

The diaphragms will dry out and crack regardless.

Yeah well all the gas will evaporate in a week, you might as well drain it out so that you at least don't have varnish.

Disgusting lack of 2ZZ-GE and K20A in this thread.

i assume likely due to the 3sgte being almost identical to the 3sge with the addition of boost pressure.

Both those engines have major issues
>performance engines
>reliable
Pick one

>comparing longevity in the event of negligence to maintain the vehicle properly
Come on now

This, EFI cars if let sit, will have trouble starting because it needs power to control the whole EFI system.

Neither carb'd or EFI vehicles should be let sit for more than a week at a time.

I havent seen a diaphragm carburetor in forever. Float bowls can stick but its really a non issue

"Reliability" in the automotive world and low maintenance are synonymous.

Carbs are not low maintenance compared to Efi, they have to routinely be cleaned and adjusted many times before an injector has to be cleaned or even replaced, in addition they have issues running in varying atmospheric pressure and temperatures whereas your average EFI system never has a problem.

Don't get me wrong, carbs have their uses, namely being a easily tunable and cheap way of getting power on an older engine, but don't try to say that they're more reliable than EFI.

>they have to routinely be cleaned and adjusted many times
While this is true, it's easy as shit to do both.

>atmospheric pressure and temperatures whereas your average EFI system never has a problem.

Bullshit. EFI can't compensate for lack of air, just like a carburetor can't. The only thing that can cure altitude richening is forced induction.

I've had EFI cars sit for years and start back up.

I've had carbed motorcycles that won't after sitting for one season.

And both of them were push started.

Funny, i've had the opposite happen to me.

Ive never had to routinely clean a carburetor even on my off road vehicles.
However carburetors suck for driving up steep grades, i will admit that much

Yeah, fuel starvation is a cunt.
I wonder how they eliminated it on bikes?

>Bullshit. EFI can't compensate for lack of air, just like a carburetor can't. The only thing that can cure altitude richening is forced induction.

Both lose power at altitude but with EFI it can at least sense the change and adjust ratio so the car will run smooth.

>B series
>reliable
I think you meant d series

Serious lack of 5VZ-FE here, dissapointed in you Veeky Forums

>The only thing that can cure altitude richening is forced induction

plenty of vehicles have altitude compensating bellows

Upper intake burnt through at EGR passage. Pic related. Happens all the time. Fix is a new lower intake that has a smaller diameter EGR passage that won't melt the plastic upper but most people say fuck that and just put a new upper every once in a while.
