Hi guys - yesterday was the end of this adventure for me. A quick trip up the road to a wrecker landed me a suitable 24 spline input shaft transfer case. After calling around 10 wreckers the price quoted ranged from $695 to $165. I headed to the cheapest option first and all is well and good!!! The T-case is off a TD27 turbo Terrano.
I am still none the wiser why there is a mix of 30 and 24 spline T-cases out there across the Z24, TD27 and maybe VG30 boxes - but hey - second time lucky. 30 minutes after getting home the T-case was on my new manual box with the low range lever in place.
The only thing I had to do today was buy two bolts because two bolts were 10mm shorter than needed on the manual box compared with the auto (another strange thing!).
This weekend will see some quality time in the shed and hopefully a box - bolted up!!
Cheers

there are some members with this information; I think I remember someone covering it.
Please try searching for it, and look in the TD27 section that we make just for all the lucky people that have them.
That is where I am going to move this so hopefully it gets more attention from the people in the know. Feel free to PM or email members that seem knowledgeable. sw may be able to help.
Anyway, tell the wife B said not to worry, we are working on it...

Thanks for your help - dropped into a Jap gearbox wholesaler this afternoon - he looked at me sideways when I told him that the input shaft on the transfer case which was mounted to the auto box had 30 splines. I will call a few wreckers and see what they have to say about it. Might look at a Z24 pathfinder transfer case and see how many splines it has - hopefully its got 24 splines and all will be solved!

Hi - I am 3/4 of the way sorting out my auto to manual gearbox change. I have paid for and received a TD27 re-conditioned manual box minus transfer case. The problem is that the diameter of the gearbox output shaft is smaller than the input shaft of the transfer case.... What gives??
Do you need a different transfer case for the manual box compared to the auto one?
Is there a difference in output shafts between the older and new model Terrano's??
The wife is going to kill me. First I bought a Pathfinder box but the bell housing is different for the petrol motor compared to the diesel one so that was bought and sold and now I have got more problems.
Any help would be great so that I can get te beast back on the road.
Cheers

well your t-case wont bolt on the gearbox. 720's have divorced t-cases, so the back of the gearbox would have a drive shaft style output.
Cheers - looks like I will have to keep my eye out on the real thing. I assume that a pathfinder petrol gearbox would fit fine and dandy - no mods?

Hi guys - there is a five speed trans from a diesel Nissan 720 4x4 on the net. Does anyone know if this will bolt straight onto the back of my TD27T and onto my transfer case?
Cheers

have a quick read here:
it only 2 pages & explains a few things
the comments i would be paying attention to are by 'old mav', 'tracteur tom' & 'its a ford not a nissan'
the last comment by old mav sums it up well
Cool - I will print all of that out and have a good read! Cheers!

The TD27 is a great engine to improve performance.
Things that you can do.
The exaust has been said before.
The air filter, remove that filter and is box, i've put a Land Rover box and air filter with twice the size of the TD27 one.
Turbo, mine is just at 1 bar, i don't wan't more, because probably would brake faster.
The fuel pump, here's is the master mind, mine is just tweaked a little, 2mm of advance, a little more fuel, but a good fuel pump house, can modify the fuel pump, and tweak it, and the TD27, can reach 160hp with that.
Mine has only 134hp, but soon it will have a modified fuel pump, to reach about 150hp , its more than enough, and it will reach 6000rpm
I looked at boosting mine - but the boost had already been wound up to around a max of 11 - 12 psi....

My IC, from a pagero/montero
Hey thanks for your pics! I had seen them previously - must have been in some of your previous posts. Do you have any pics of what you did on the turbo exit side of things?
Did the intercooler make a considerable difference in performance?
I have a 13B turbo - rotary engine top mount intercooler sitting in the shed. I know that air pumping through a rotary revving its head off far exceeds the TD27 but I was thinking the unit might be a little bit on the small side given the capacity is like 1.3L or so...
-
Hi guys and gals, does anyone have any photo's of front mount intercooler locations? Running the pipework is not totally impossible with some mods to the existing inlet manifold and piping exit the turbo but there is bugger all room for the cooler. Any thoughts / successes or is the less efficient top mount pretty much the only / best option to keep the length of piping to a minimum?
Cheers

wow this is an old post
3. fit a holley red fuel pump near the tank. helps with power, km's and lower egt's
Quick question, what is the performance adder of putting the elec fuel pump? Is that to remove the need for the mech pump and the hp to spin it? I have been pondering this since you raised it and seems a little out of the box.
I have replaced the rear muffler with a piece of straight pipe and under the advice of another I am running some of that lovely biodiesel (from your side of the border) from SAFF. I have only driven around 90k's since adding it but the thick black smoke has already pretty much disappeared from the exhaust pipe under heavy acceleration and kick back of the auto.
Looking forward to your response - cheers!

Hi Guys,
Love Pathfinders and located in Melbourne.
Looking to converse with other Aussies on this site about this much underrated 4WD.
Message me or leave something on this forum so we can get the conversation started.
Thanks guys,
Michael.
Hey Michael - i'm from Melbourne. I have a TD terrano. Do you head out much? I'm searching for a manual box and looking at options like an RB30 etc. Need to get the measuring tape out to see what would actually fit tho....
-
Yet a Holden motor is?
j/kFunny how the old commodore motor was the same as the Skyline motor from the same era (Staight 6 one).
Thanks guys - I have some quality food for thought.
First things first (today) is my alternator.
Second is the exhaust
Third is looking at fit my intercooler (in the shed at the mo)
Fourth - timing / tuning.
Fifth is continuing to sort the manual trans - keeping an eye on this RB30 manual gearbox and transfer case - cause the auto is so crap!
Sixth - with the above box and checking out mod's two to four in place, either the RB30 / RB30ET (i think) or spend the money on the TD (inj and pump).
Have a great weekend to all
-
forgot to mention
have you ever checked you valve clearance
as with any motor incorrect clearance will give crap consumption & crap power
Cheers SW - some good advice there! That's funny - the first thing I thought of when it came to ordinary fuel economy was getting it tuned by a pro and seeing if its running rich etc or not.... Since then I have been hunting around for someone to look at my timing - no joy so far... I see your in South Oz, but do you have any thoughts / recollections of reputable tuners in Melbourne at all?
To be honest, I just love the sound of the turbo and wouldn't like to see it go in place of the V6. I do also love the torque off the line from the diesel motors...
I think this weekend I will look into my exhaust and cut off the muffler and see what diff it makes in terms of noise, performance and economy. The misses will hate it but its my rig so she doesn't drive it!
My alternator died a week and a bit ago so this Sat will be ripping that out and replacing it with a newbie.
Thanks for your advice and waiting to here your feedback regarding the economy of the V6.
Just thought of another question, do you think anyone will have any drawings of the TD27T gearboxes (manual and auto) and the petrol gearboxes. Does anyone know what the part numbers are for the different boxes and whether the petrol 2WD boxes will bolt onto the TD27?

one conversion i think would be a-goer, would be a zd30 from a patrol (its a different setup to the zd30 navaras), i have learnt a lot about why they have a tendency to self destruct, thanks to patrol4x4.com, so a few key mods and i think the zd30 would hammer in a d21. its direct inject and twin cam, with the right mods i reckon it would make the 3.8L look a bit drab.
What's the economy and power like with the 3.8 V6 conversion?
A guy has a 5 speed and transfer case for an RB30 out of a Patrol for sale at the moment - could be a good option?? Thoughts?
I am in two minds, if I go to the hassle of a conversion with say a V6 motor, then why not go the whole hog with say the all alloy 4L toyota V8 - 1UZ? The thing I like about the commodore is that there are so many of them around that gearboxes and rebuilding motors etc is cheap. I spent years driving European cars and you get burnt mega $$ for parts.
Too many options!

Hi guys - I have been looking at options for an engine swap - has anyone bolted an SR20DET motor and transmission into a WD21 before? I want to keep 4x4 so the trannie would need to bolt up to the transfer case. I have heaps of access to tools and materials and SR20DET half cuts are fairly common. My TD27T needs injector cleaning, fuel pump etc and even when all that stuff is done it won't come close to the power of some other motor.
The four door 4x4 suits me down to the ground but the stocker TD is all no go.
I have the three speed / over drive auto and its wearing out so its time to assess other options.....
I saw pics of the VH45 but that's too much work to put in.....
Would welcome thoughts!
Cheers from Oz (Melbourne)

wel its been way to long since i started this post but ive finaly got some things done and some results:
first thing i did was fix the leaky fuel pump to deal with the sulphur content in the diesel and with that i notices an improvement in both economy (duh) and performance (only just)
next i replaced the water pump (no real improvement other than it ran cooler)
then i put togeather a custom air in take with a kn air filter* (large improvement in performance giving the pathy a nice burble in the exhaust)
i finaly saved enough to buy a sports exhaust, a mandrel bent 2.5 inch straight through (no muffler). )ha ha ha it now sounds like a mac truck and the turbo whisle is extreemly lould, verry large improvement in performance, noticable improvement in econemy )
ive also been useing a fuel additive which after a few tanks of fuel it has lived up to its prommices (more power, better econmy ect ect)
my stats so far:
fuel use- before: 400-450ks per tank
-after: 700-800ks per tank
performance
Before: will not spin wheels,
traffic light drag
yah maby against ... scrap that ,just wouldent try it
after : will spinn wheels un till mid, high 2nd consistantly , with new tires.
traffic light drag: any thing up to heundy exl spec is a good chalange
After much reaserch and speaking with local 4x4 stores and both kn dealers and compeditors i have come to this conclusion about dust injestion: the kn filter only becomes a problem with dust when it is washed repeatedly at to close a intervals the cotten degrades and allows is reduced in affectiveness .
so aqs long as i main tain the filter at the spesified intervills i should be right.
next up in gunna give the motor a rest and work on the audeo system 4 a while
Does the new exhaust make that much of a difference? I love my TD27T over the TD27 and the crappy petrol and my fuel economy is lousy. I have been thinking about a motor and trans transplant from a VN to VR commodore but its kinda out of financial reach at the moment. The V6 motor isn't really that smooth but at least has a bit more poke. How noisey is the exhaust without a muffler??? I did that in my old land cruiser - sounded awesome hearing the turbo spooling up!!!
TD27 turbo terrano / Diff Ratio's
in Diesel Engine Discussion
Posted
Hi all - does anyone know if the auto and manual gearbox versions have different diff ratios?
Just got my rig back on the road after doing the auto to manual conversion.
Its near on 3000 rpm at 100 kph in fifth gear.
Runs smoooth and all gears shift nicely but rev's too high.
I spoke with a guy a while back and he said that his TD27 turbo rig rev'd to less that 2000 rpm at 100kph.
Does anyone have any thoughts?
Thanks
