3B vs 1HZ

[crushers]

sorry, i misunderstood.

nope, i have to admit my experience is just with the old 3B, i have pulled apart a few 2H and one 2LT so that is not enough to make any form of judgement...
oh and lots of the F/2F engines...
cheers

Thanks!

In Norway there are many 2L-Ts and 2H engines, but only a few 3Bs. Anyway, there is allways a short of 2L-T heads, because the old ones cracked. The 2H seems to have very few problems, despite more kms. The 2L-Ts typically have 250-300 thousand kms on them.

3Bs are not known to have any problems, but I guess there are not more than around 100-130 cruisers with this engine here. I know of about 40 of these, the one with the highest mileage beeing a bj75 rescue veichle with 700 000kms and a worn out H55F.


A friend of mine who is a cruiser-enthusiast and a Toyota mechanic told me to mount an intercooler at the same time as I turbo my 3B. The reason was that this engine was sensible to heat he told me.

i forgot to ask him how many heads he had sold during the 85-89 mine run...
;^)

probably very few. if underground, they turn them way down on fuel(no smoke underground if possible). there is no overheating period. They idle forever at time,

They are not running at high rpms. Or on long hills under highway speeds.

I would be suprised if any heads were bought up during that period.

Natural progression does go to the 1HZ engine.

3B are very underpowered for 5000lbs trucks. But I am not switching yet.

When the time comes it will get a 1HZ, or I will buy a JDM with one.

For now the fuel sipping 3B is the best choice..........

I will drag this post up again to beat a dead horse once more.


If I were building a truck and had to choose engines, no brainer for me it would be the 1HZ.

Now if I had a budget and had to pay 3000.00 for a 3B H55 split case combo(lets say over 200000KM) over a 7500.00 1HZ H55 splitcase(usually with vacume shift)(80 000KM), it may be a deal breaker.


Now if a customer came to me and asked which I would use, I would push real hard for the 1HZ.

After driving the 1HZ for a month now in FJ45, I just plain love that engine, smooth and very quite. Cold starts are little more than a almost invisible puff of smoke.


Also after standing beside Waynes 75 series at Pismo, I was floored at how unreal quite his rig was, not sure if it was the turbo or PI???
