What engine should I go with in my Cruiser ? 3B or 1HD-T ?

[YoYoHo]

I am building a 40 Series MWB Cruiser and have the option of going with either a 3B, a 3B with a Turbo or a 1HD-T (1990 ) in it.

The aim of the build is to make a reliable daily driveable Cruiser.

It is sitting in a 1964 FJ40 Chassis which is running Custom Suspension so fit and finish is not an issue and I have the matching 5 speed for whatever combo I go with so it is all factory fit and finish so to speak.

I realise it is a bit of a weird question but thought I would put it out there and see what those with more experience on the engines has to say.

I like the simplicity of the 3B but the 1HD-T is hardly complicated and I am guessing parts for the 1HD-T will be around for longer than the 3B.

I struggle to see how you can compare them. One is a smaller IDI 4 cal known to be gutless. The other is a flagship DI factory built for turbo and capable of large and reliable power. Despite what reports on here my indicate 1Hd-ts are known here to be long lasting reliable engines. Change the turbo, time it up and they really fly. The 40 series engine bay takes a Toyota 6 because it was made for it.

Why would you not put a 1h* in it?

Any idea which would provide better fuel economy, between the 3b-T & the 1HD-T? A trubo'd 3B with just so-so boost produces more than enough power for a fun 40 series. The 1HD-t would be cooler, but I don't think you would need the extra power to be happy unless you are planning on tons of regular long road trips in it maybe. So if the turbo'd 3B is cheaper/easier overall to get & install & also gives better fuel economy, then the turbo 3B wouldn't be a bad choice. But yeah, if the economy is the same & money is no object, then the 1HD-T would be far neater to see in there.

I think there's no question the 1HDT is a better motor. But what it really comes down to is: what is your budget? A 3B can be found a built on a budget. A good shape 1HDT will command some $$. In a 40 series the economy will be similar. Generally though direct injection wins in the economy department.

Yeah that is what I am thinking

 

[Varty Yo]

Budget and whats available to you. I love my turbo 3B but would gladly swap engines haha.

The 3B will use less fuel. Because you'll be driving slower everywhere.

If you drove a 1HD-T at the same speed as a 3B, there'd be little in it.

What about a 1pz?

 

[gerg]

alh? A guy in the 40 section did one and it looks pretty cool. Those Mercedes engines work well too.

 

[Dougal]

What about a 1pz?

All the downsides of a 1HZ, plus it's a dead end for parts.

 

[mudgudgeon]

Is this really a question?

HD-T is far superior. They are long lasting if you do the appropriate maintenance. 500k km plus is totally achievable with the right PM

A HD-T in an 80series will get 12-13 litres or better per 100km if driven for economy, it'll do better again in a light weight 40.

It will have plenty of power for a 40, and let's be honest, too much power is never enough!

All the downsides of a 1HZ, plus it's a dead end for parts.

Plus it's missing a pot. Really no upside

I’ve only ever driven a 13BT (3B turbo) in a 60 series with springover and 35s with factory gearing. It had plenty of pep. In a 40 with appropriate gearing it would be fantastic. The 3B runs on the smell of an oily rag, so hard to beat for economy. The 1HD-T is a phenomenal engine, but as stated, almost overkill in a 40, and will cost way more up front than the B engine. I’ve owned a bunch of NA 3Bs in 60 series, and I actually enjoy driving them. It’s definitely not for everyone, but it’s nice to not be in a hurry all the time. When I get in my 375 hp / 850 ft-lb Cummins powered rig I tend to drive like an ass. Fast everywhere. I’m a much more relaxed driver in my old rigs.

 

[joseywales]

Yeah that is what I am thinking

I just read you are in SoCal. That changes things a bit. You will NEED the extra power of the 1HD-T just to survive down there. If you live in a small beach town like Dana Point and just drive a few miles up or down the PCH, the turbo 3B will be fine, but if you plan to get on to the freeways at all, go for the power. I’ve driven crazy roads in Australia, South America, Europe and Central America. The craziest driving of all is the Central and Southern California freeways!

Thanks for the feedback. Situation is that I have a 1990 80 Series that is factory Manual / Turbo Diesel / Part Time 4WD which is JDM and I recently got written confirmation from CA DMV that due to rule changes I can no longer run it with CA Tags without getting a Lab Test that runs $10k.

So I have the option of using the running gear in my Project Build or selling it on. I have a 3B for the project at the moment with a garret turbo etc and I was looking at the 80 thinking man maybe I just blend them together so I would have an FJ40 Chassis with a BJ46 Body on 60 series diffs with an 80 engine and transmission .. sounded like a good plan lol.

That left we weighing up if it was worth the hassle to go from the 3B and H55F to the 1HD-T with the H150 .

I figure $$$ wise when the dust settles It will be a few $$$ extra to kill the 80 to use its engine but if I sell off the 3B and H55F it will offset the $$ some what.

The H150 seems to be about 8" longer than the h55 which will need some magic but as the wheel base on the 40 is 12" longer than stock I figure it will still have a rear tail shaft that is 4" longer than a stock FJ40

DO NOT GET A 3B. The 3B is a great and reliable little engine, but parts availability is a joke and it can be a nightmare to maintain and/or repair any engine troubles. Also, as you well know (you have a turbo setup after all), the 3B is absolutely gutless.

I say this after having spent countless dollars and hours in sourcing a replacement head for the cracked one on my 3B Bj60. I ended up getting really lucky and scored a used B head on ebay....

 

[YoYoHo]

Oops it has the H151F not the H150 so 1st is a bit higher and the T-Case low is a little lower

These 2 aren't comparable in any way and there are 5-6 other diesel engines in the toyota range in between these . The 1HZ goes quite well in a 40 and so would a 14BT or 15BT and I have always hoped someone would try a 1KZ T

What do you mean they aren't compatible at all ? I realise they are different engine and have different transmissions . I am not planning on sharing anything between them

 

[mudgudgeon]

comparable

compatible
