Thread: 12 valve /24valve

Toyota landcruiser vx 80 series turbo
I don't understand the 12v/24v thing
Could some one who knows explain this in simplemans terms please, ending with which one is better.
Thanks.

Mines a 24 valve and it goes pretty good. I'll be following this too. I've wondered what the deal is

The 24v has tiny bit more grunt as standard but if you mod them harder with a bigger turbo etc the 24v delivers more grunt.

Also bragging rights/snobbery

24v (1HD-FT) has about 6Hp more and 20Nm more torque that the 12v (1HD-T)

Thanks for the replies so far.
so , is it a deal breaker, 6hp/20Nm doesn't seem that much in the big scheme if a bloke wasn't going to go away from factory consideration?

Not its not, considering how much extra some people want to charge because of the extra valves

less than 5% more.

They also redid the big end bearings in the 24V so you don't need to change those every time you do the cam belt like the 12V.

That one is the deal breaker.

Or every 20 thou if the engine is making power.

Ahh, so gadgetman if buying one, a bloke should indeed buy the 24valve model if only to avoid the cost of bigend bearings every cambelt change?
I'm guesssing that would be every 100thou?
Also at what cost Big end bearing replacement please ?

Every 20 thou? Truely

Having sunk many many thousands of dollars into a 80 my advice would be dont buy one unless you know its owner and service history and you would trust him not to shag your wife if for some reason they were stranded together for a year.

The 12v can easily be made to make much more power and tourqe but the bottom end is weak and they will crack pistons if over fueled. Autos are big dollars to fix and most of em have done 5-800k km regardless of what the speedo says.
Every part on a land cruiser is 1.5-3 times the price of the equivalent part on the same era hilux and having twice the power and weight wear them out with alarming regularity.

Dont get me wrong I loved my 80. For a 25 year old diesel 4wd it went like fuck was comfortable quiet handeled heated seats fridge and ice maker etc etc etc but matainace costs and running costs were astronomical.

Guess thats what I wanted to hear VC from somneone who has had one
A couple of recent threads lately had me wondering so..
I was looking on t/m andf there is a green one at priceright cars in Auckland that they say has done only 142k and looks good etc, thought I might sell the shagger, buy that and never have to worry about anything else as long as I can drive
However.
it appears it doesn't quite work like that, its a 12 valve one for a start.
it aution number 1001755982

If anyone wants to look.

I would have another if I was in a position to just have it as a weekend truck or project non road legal off roader.

As a daily driver it just made no sense.

That one seems very expensive and its age and low ( like ridiculously low!) Kms raises question marks to me.

cheers.Seems it could be , "better the devil I know'
though there nothing in particular wong with mine
Ha, that I know of.
