TB42 vs TD42

[MQ MAD]

Why do a simple question of whats better between two engines does the mention of snails get thrown in the equation ???

My GQ is the TB42 EFI Auto
100% stock nissan and it has enuf power to do everything i need
Heaps power , pulls large loads up hills
Only donwside is the economy (or lack off)
But its 3 tonne ,aerodynamics of a brick coupled with an auto
Wasnt certainly bought cause it economic thats for sure

Diesel Vs Petrol
Personal choice

[YNOT]

I'm just asking out of curiosity; a few people have mentioned that the TD42 engine is more grunty than the TB42, but looking at the specs, the petrol put out 129kw @ 4000rpm vs the diesel 85kw @ 4000rpm and the petrol produces 330Nm @ 3200rpm vs diesel 264Nm @ 3200 rpm. So the petrol would seem to produce significantly more power and torque at the same rpm than the diesel. Only the 4.2 diesel turbo (GU) puts out the same torque but at lower revs. Is this the one that's being refered to as 'more grunty'?


The original question did mention turbo's, and you know how easily we get side tracked!

Yep
We have ways of making you "Torque"

Id certainly be interested in a seat of the pants 4.2 TD GU Vs GQ TB42 comparison

And we all no figures on paper dont mean much in the real world

You are exactly right about figures on paper not meaning much. On paper the GQ TD42 naturally aspirated motor and GQ RD28T have very similar power and torque figures, but driving them reveals them to be completely different.

I always thought one drove a TD42 and towed an RD28T

[MQ MAD]

Waha waha waha
Thats absolutely gold !!!!!


Seriously the RD28Ts are alrite
They beat walkin i suppose
But i reckon if ya stepped up to maybe a brisk walk
Well thats different

My TB42E has extractors and 2.5 inch exhaust , i have fitted 4.375 ratio and run 265/75/16 tyres

The lower ratio has certainly woken the big behemouth up a bit , it almost takes off a standing start like a V6 Commo and loves to rev through the gears , more torque is felt through the rev range and is heaps responsive its better for towing , on inclines , headwnds , offroad 4wding and better engine braking on declines

It does not use any more fuel than before with the 3.9 ratio as it doesnt labor as much as before and only revs approx 250-300rpm more on the highway in overdrive with torque convertor locked , still get 400-420 highway km from 88litres LPG

I love it on the highway when overtaking , manually kick it down to 3rd and floor it and she just revs and pulls away .
Also with the 4.375 ratio it makes the extractors and larger exhaust do their job a lot earlier rather than waiting for the revs to build up with the lazy 3.9's

hi guys... i have td42 diesel with my nissan patrol at the moment. the reason diesel make lots of noise. my friend ask me to swap my td42 with his tb42 carburetor.. so do you guys think it will be worthy to swap with him... plz let me know.. i will highly appreciate you guys valuable advice... i m just confused which 1 better tb42 or td42 thanks

Pretty much all the differences have been listed above. It really comes down to personal choice and the type of driving you do. You should just have a drive of both and feel any differences for yourself. Some people swap but moast are happy with what they have. I got a petrol with auto because thats what i wanted when i was looking for a patrol. I am happy with it

Hey mate what was rough cost of changing the diff gears?
