Outer Limits 4x4 Board

I recently purchased a 4BD1 that I am intending to place in either a FJ45 UTE or FJ45LV wagon the weights on these are 3800 lbs. for the 45UTE and 4,070 lbs for the 45LV wagon.

I wanted to know what the weights of these Rovers were that had the 4BD1 stock equiptment???

I do not know to determine what year my engine is to know whether it has the newer pistons suitable for turboing...I guess I'll see how it goes NA and decide on that later.

I also do not yet know what transmission/transfer case/differential set-up I will need as well. I believe these 1965 toyotas have 4.11 differentials and they had a 3 speed transfer case. I know for sure the 3 speed transmission has to go for one with overdrive.

thanks for assistance

The motors were designed for small trucks to carry up to 9 tonnes.

I have 4.11's in mine with a 5 speed santana box and 35" tyres and it is spot on for me.

I think you misunderstood my question......

What is the curb weight of the Land Rovers with the 4BD1 engines???? are they 4000 pounds....not what payload they carry.

I thought he was helpin you out with this bit.

My 110 county with NA 4BD1 weighed about 1900kg last time I weighed it with 2 people, half full fuel tank and has bullbar, side rails and winch. Is this what you wanted to know?

The lightest vehicle to have a 4BD1 was the Series 3 Stage 1. The standard (Aluminium V8) Stage 1 was about 1500kg kerb weight, and more like 1700kg with 4BD1. As stated above the later 110s were more like 1800-1900.

Plenty of people have turboed an early model 4BD1 in a Land Rover without problems.

My 4BD1 weighed about 320kg on the workshop floor.

I haven't put the vehicle over the weighbridge yet.

Maggots gearing is about right, his overdrive is about 26%.

If you want a simple instalation, get a Santana (LT85) transmission and LT 230 transfer ex 1986 onwards diesel 110 county. That is what went into the maggot mobile.

These engines will take turboing well, you don't need the turbo engine, as they were over engineered for truck use, and the duty cycle in a 4x4 is nothing like a truck, in which these engines will do about 1 million km.

I turboed my standard 4BD1 and I'm running 10 psi at the manifold, it is intercooled and has around 500NM at about 2200 rpm. This engine had done 430,000km prior to blowing it, and uses 1 litre per 10,000km of oil.
I'm very happy with its performance, economy and despite what some may say, the extra weight up front seems to be no hindrance whatsoever to its offroad performance. Go the 4BD1 with a turbo.

Boaty - it would probably be easier to sell/swap your 4BD1 for a toyota 3B diesel. These engines go and sound a lot like a 4BD1, but will bolt straight to your toyota running gear (and can be turbo'd also).

The 13BT and 15BT are also options that will bolt straight in, but I have heard they are relatively light-duty compared to the 3B and 4BD1.

Good idea Ben, but every B series toyota diesel I've pulled the head off has been cracked, and all precomp chambers had to be replaced etc. I honestly believe the performance and lifespan would be so much less than a good 4BD1 for me to want to fit one.

But, the gearbox and transfer fitting etc would be easier with a B engine...

Your call.

I see you have it fitted to a NP435 ? - why not go a NV4500 ?

don't know if they have the same bellhousing mounts - but chances are???
