I have started the transformation of my 92 model dualcab NAV i have picked up TD27T auto out of terrano 40,000 on clock looks very new clean . How hard is auto to switch into manual?. Engine has arrived with cables galore suspect it is modern and computer accompanied will i need to go whole hog and buy comp as well? or can i run it without. Intercooler wont sit in mine where it is on engine will have to relocate. Any ideas on mods for extra power and highway capability as will be my main transport 4 days a week. What is a decent brand snorkel set up assembly?. Would love to hear any ideas no matter how slight really appreciate peoples time. Am really hooked now on making the NAV complete package , already have ARB and driving lights, is already lifted quite high , want to have 32" and paint white sunnraysia wheels black , already have custom cage fitted to tub with two locking points, want to fit tray instead for hounds. Will eventually turn tub into trailer. What size pipe for TD27T will be suitable for stopping back pressure and promoting optimum flow?. Is gearbow rebuild a big deal for these units?. will post pics very soon would love to hear peoples ideas thanks for peoples time.
Go the D21!!

Hi mate.
Need a box plus bellhousing and should bolt up, plus you'll have to track down and remove the extra engine controls for the automatic. Difficulty rating five out of ten.
If it is indeed a TD27Ti with electronic control, it will run like absolute **** if at all without computer, buy computer.
Hmm. Where is the intercooler located? The engine bay is the largely the same from D21 to D22, and the Terrano II is built on a D21 chassis, the next Terrano is built on a D22 chassis. Or is the issue that your bonnet doesn't have a hole and scoop to accommodate it?
Exhaust for power. Besides that all you can really do is up the boost and fuel following a bigger exhaust, it's already TDi so making everything on it bigger is your only option. You will see limited results from a bigger intercooler, you'd only see improved performance when towing etc, high load, wide open accelerator.
For the highway, change your diff ratios and/or fit bigger tyres. Getting a pair of crowns & pinions for these D21s is expensive though, sucks to be a 4x4 owner. What's your present axle code as per the data plate under the bonnet? The other option is to fit alternative overdrive ratio gears from a VL commonwhore or 4x2 Navara or a plethora of JDM cars, but the percentage improvement in cruise RPM is minimal via this method. Consider asking for these ratios if having your transmission rebuilt.
All the snorkles I've seen advertised for it are about $400 RRP and are all the same. They're simple and will work fine as long as they're installed correctly.
Can go up to 33s with a suspension and body lift.
Stopping back pressure? You'd need to have no pipe. 3" is overkill, 2.5" is usually enough, but the story is usually the bigger the better. To cut the cost of your exhaust, go with a bigger pipe size but don't bother with mandrel bends on anything below about 70-80 degree bends as they drive the price up. Also, shorter is better so get into reading those ADRs to work out what is acceptable on your vehicle, fit a side exit in front of the rear wheel if you like.
If you're prepared to cope with a little bit of awesome sounding snorting, go with no resonators or mufflers. The TD27 is not loud by engine standards and with the turbo, the need for a muffler is mostly mitigated. Run the engine without a muffler when the time comes and see how you feel. I've heard they can pass sound requirements without mufflers/resonators.
Yes. It's a big deal for all vehicles and this one is no exception. Try and get a second hand box from a 4x2 Navara, 4x4 Navara, Pintara, or steal bits from the tranny of a VL commonwhore with the Nissan motor in it. Do not labour the engine to the extent of revs dropping with the accelerator down with the transmission in fifth gear as you WILL f*** the bearings.
Keep us posted and get those photos up, I'm sure we're all very curious to see them. Good luck!

A suggestion: Most people keep abreast of all the forum topics they're well versed in and some that they aren't (I do that) so it's not necessary to post the same thread in two topics. It just gives people the ***** rather than increasing your question's exposure. Cheers!
PRO NAV your knowledge has been invaluble mate i really appreciate it saw my mechanic today and we were dicing up if we need to get a comp or if it will run ok without , the intercooler sits to the rear and there doesnt appear to be enough room along firewall it looks as though it will be to tight are you saying that it may infact need to make space via bonnet and not firewall? we were going to bypass intercooler altogether , i was goin to engineer pipe to bypass completely, and thought that comp was mainly to operate intercooler anyway. i will take photos of new engine and post tomorrow maybe that will clear up a lot once again thanks a lot great help
The only way the intercooler is going to be effective is if you can get some cool air flowing across it, so that the boosted air passing through from the turbo is cooled down.
If you mount the intercooler on the firewall, there is no chance of it doing its job. There are some good pics of how a D40's intercooler is mounted in this thread.
Sure, it's not the same as yours, but it's fairly typical of an automotive intercooler. Mount it in front, where it gets the coolest incoming air.
The intercooler works by passing hot air internally through the intercooler and cool air externally, so that the internal air loses temperature - and therefore volume - effectively increasing the amount of air in the combustion chamber.
If you don't have cool air externally, the thing is pointless - except maybe to catch broken turbo blades when they come flying off in a disaster!

sorry guys i should have beenmore specific it is not an air to air intercooler it is air to water that is why it is hiding behind engine along firewall , and we are wondering if we need to run it , i thing wiring is for pesky intercooler control hopefully not computer, finding out today from supplier ins and outs but will still post pics this afternoon. If i dont need to run comp it is all systems go just need to find new starter motor and design air intake as box didnt come with engine might need some serious thought with this one
It's an Urvan engine (E24) you've got there, the van's engine bay is very different to the Navara's. The intercooler is a calsonic water to air. Look in my gallery to see mine which is still waiting to go in. Your biggest issue is going to be locating a second (or third if you have air con!) radiator for the air-water intercooler, it's not plumbed into the engine's cooling system.
I had my doubts about it being computer controlled, "wires galore" may just be a perspective thing. If it was computer controlled, you'd be contemplating suicide looking at all the wiring.
New starter motors are available from Ashdown Ingram, don't bother with Nissan as the price is too high. Alternately consider wreckers, the starter is the same in the TD23, TD25, TD27, QD32 and ZD30 engines but confirm on site as the internet is a liar. Usually around $300.
pro nav your wealth of knowledge is second to none im very lucky to have you helping me out question can i bypass the intercooler , do i need it ? being its water to air ? can i just make sure i have pod system for air , because it is to tight against firewall , my mech has told me we dont need it i wont be looking to tow much at all, will it run to hot ?
mate i had a look at your intercooler exactly same as mine is this engine much chop i just thought it was a terrano engine, my unit is very clen pulled it apart a bit very very clean , is it a good idea to cut this intercooler out to make it fit?
It's the same engine, that's fine, as far as I know the only issue is that intercooler location, not sure about accelerator linkage but shouldn't be an issue. A lot of (all really) JDM cars and engines get a bit of a mileage haircut on the boat ride over, so take their mileage with many grains of salt, but if it looks clean then that's great. You don't HAVE to keep the intercooler, but:
A) do it all now and save yourself some trouble when you decide you do want one, you seem keen for as many ponies from the engine as you can get and an intercooler is a pathway to upping the boost as it will lower your EGTs; I say it's typically only for towing because the engine is rarely worked that hard, but you might be a race car driver or looking to sling serious mud!
B) if you don't fit it now keep that intercooler in a box somewhere! Water to air intercoolers aren't cheap!
C) if you choose not to fit it, your mechanic or a diesel specialist needs to adjust the wastegate to reduce the maximum boost as the intercooler is now gone, and subsequently the fueling will need to be adjusted and the rig dyno-tuned.
From my experimenting it seems the intercooler would fit on the passenger side of the engine in the engine bay with the fuel filter relocated. It would require a few 2" silicone bends and some stainless or aluminium pipe to route the intake air around the engine bay but nothing as gross as a front mount air-air.
Actually I've just realised, that Urvan engine might have a sump that's incompatible with the front diff. If your importer sold it to you as a Terrano engine, you might need to have a talk with them quick smart. They can either swap the engine you have for a 4x4 engine, or give you a 4x4 TD27 sump.
pronav how are you once again im tapping into your deep well of knowledge , im thikin of puttin an aftermarket radiator in somethin big , im really worryin about keepin this donk cool now i have bypassed the water to air intercooler, is there a decent air to air for the TD27T i can purchace is top mount better than front mounted? really thinkin i need to keep this baby cool if only to promote ample ponies as you said,
christ sorry mate i never noticed the second page to answer you question i found the motor at 4x4 spares at Kotara Newcastle and it was cheap as chips i live in bathurst nsw and it cost me $1650 deliveredto my mechanics door god i hope the sump matches up becuae this is turnin into a costly exercise.
Front mount is typically better than top mount as it's easier to convince air to flow across it. I've never heard of a kit specifically for the Terrano so it's a matter of finding a nice second hand air-to-air and going custom on its ass. Take a look at Dave's intercooler setup for inspiration and a budget.
As far as radiators are concerned, anything from a V8 you can afford and make fit, there are no hard and fast rules. Just make sure you keep the standard thermostat in the system so that it runs at the design temp. Cooler doesn't always mean better, there is a temperature the engine is happiest at, about 87 or so. Consider an extra electric thermofan with the existing radiator to save money.
Good luck with the sump.

Cheers pro mate is there anything governing what type of intercooler i can use ? what type is preffered ? could i adapt a 180sx or any other ? and touching on radiators what are the limits on what i can use ? i wanted to get a decent alloy one to encourage cool flow can i go to big? basically wanting a set up for the new donk being i have cut out water to air set up , also need new air filter set up , stock one never came with motor , am i heading in the right direction getting a decent snorkel pod set up , with new radiator , and front mounted air to air , will that keep the TD27T happy?
hi m8 pro-nav is dead on the mark about sump the terrano sumps are more highter than the standard td2.7 im lookin at do same job in my td27 95 navara .iv found a couple things out like i can use my 5speed if i change flywheel etc .good luck with navara m8 hope things go well
There aren't really types beyond air-to-air and air-to-water. You can use anything you want, just look at the measurements and see what you can squeeze in. It doesn't have to be huge. Try and keep it to a 2" pipe size though, makes things simpler and cleaner.
You can never go 'too big' with the radiator as the thermostat will just slow the flow down to get the right temperature, so bigger is better as long as your wallet and engine bay space can stretch that far. For increased hot weather cooling though to take advantage of a big radiator, you'll want to add a second water pump, look at Bosch or Davies Craig.
Consider an air filter setup from a commonwhore or a Landcruiser or similar, something with cheap plentiful filters.
mate i have bypassed without ecu do you think thst was a bad idea im not looking to do anythin extreme in this rig as far as off road maybe some mild crawling and very rarely some light towing mostly country miles with me and me hounds chasin some hogs nothin to heavy duty , but in saying that being that the TD27T and bits and pieces are so cheap i might as well prepare for the lot will post pics soon loging progression should be a wild looking rig that will be economy wise and not to sluggish cant fu>kin wait!!!
