Build of Australia's FASTEST PATROL ...Potentially, Using RB26DETT Goodness :)

Nothing but high rpm will get you through the mud. Remember, where Mudslut and i live lol, mud mud mud mud.........

Same story here. Power > torque when it comes to mud. Pretty much everywhere else though I'd rather the torque.

But you drive like a granny anyway winnie!?? lol

Ok from what i have seen in seriously big mud holes the opposite occurs high power at high rpm makes them bog down dig into the mud further and that's when they get stuck.
High speed entry into the mud works for me though the momentum helps lol.

Some more videos,RB25 in snow , RB25 in mud

That is Bl00dy amazing! That trol is off its head. If yours comes out like that, you'll be whoopin @rse all over the coast!

Not offroad lol, the Party Bus turns into a different beast once it leaves the bitchy

That's not mud

[taslucas]

I know what your saying 97_gq_lwb, but im talking more about greasy hard mud, muddy hills, ruts, clay etc.

heres a mate at my place last winter. TB42 33's, 3" lift, rancho adjustables.. I had a bit of a time trial day.
You gotta rev 'em in the mud

…The first 2.6 L RB26DETT featured twin-turbochargers and produced around 280 hp (206 kW) @ 6800 rpm and 260 lb•ft (353 Nm) @ 4400 rpm. The last series of the RB26DETT produced 280 PS (206 kW) @ 6800 rpm and 289 lb•ft (392 Nm) @ 4400 rpm. } The reason for this discrepancy is a gentlemen's agreement between Japanese automakers to limit the advertised horsepower of any vehicle to 280 PS (276HP). It is widely known for its strength and extreme power potential. It is not uncommon for 600 hp to be achieved without modification of the engine internals. With regular maintenance, many of these engines have been driven well beyond the 100,000 mile mark with a few heading toward 200,000 miles. With extreme modification, the RB26 motor is capable of power in excess of 1 megawatt (or over 1,340 hp)…

Seems you have your goal set on the RB26. Don't be too quick to believe what wiki or some 'review' website tells you. The RB26 will not make decent (READ inexcess of 300kw @ the wheels) relaible power stock day in day out the way you and it shoudl be driven, and that is hard!

First the cercamic turbo's will fail due to heat at high boost and you wont get a lazy excess of 300kw @ the wheels without a cam, larger injectors, turbo upgrade and some forgie's for safe keeping and of course a decent ecu, hopefully one that goes mafless and a good tune. RB26's have the capacity to make crazy bullshit power for such a small capacity motor. But you just ain't gunna keep it for long unless you build it right the first time, or drive it like a pussy, and you ain't gunna do that.

You will find by just turning up the wick (boost) will net you easy gains in HP but you only need look at a RB26 the wrong way and not have something done correctly and it can and will cost you big $$$.

How much confidence do you have in your mecho? How many RB26’s they worked on? Don’t let them tell you “it’s just an engine, same as any other engine”. It ain’t and there are some specific tings that you either just know or you don’t when working on them. I used to drive nearly 4hrs to a one of the tops workshops in Sydney (Silverwater Automotive) to get my GTR worked on and motor rebuilt. One rebuild was simply because another workshop didn’t put together the harmonic balance assembly correctly and the keyway thrashed out.

Don’t get me wrong I am not a hater but don’t be too swayed by what you read on the net about the RB26 pumping out big power out of the box. Stock GTR's RB26' are not particularly fast or awesinspiring. Also, I thought TAS didn’t have PULP, or at least that’s what some of us mainlanders have been told? The RB26 only runs on PULP.

…I'm going to be keeping the rb26 twin turbo with stock turbo's or slightly bigger turbo's. doing everything I can for response like short as cooler piping most likely water cooled, tuned exhaust manifold, external gated turbos, twin filters and a custom 3" or 4" snorkel, along with a well tuned ECU. The Patrol is currently getting Low ratio diff gears installed along with a front locker. It is usually used in mud so I reckon it will be in 3rd gear and on the limiter a fair bit. I reckon it's going to be ok for what I want it for.

Don’t bother too much with the larger turbo’s if you after response. Nissan didn’t pour huge amounts of money into R&D to cock up on turbo’s. They are well mated to the engine for response and minimum turbo lag. Go bigger if you intended upgrading other go fast bits too otherwise they won’t produce significantly more power over stock for the price.

Cooler piping – keep it down sure, keep the bar and plate stock cooler too, you don’t need bigger for you application it may just end in lag. GTR’s have the best stock cooler by far. No idea for a air-to-water cooler thou. Just another expense possible for not much gain. Also then no one will see your stonking great front mount if you just have some pissy under the bonnet air-to-water unit.

Exh Mani – HKS make a tops one, stainless with a separate pipe for the wastsegate. Which brings me to my next point don’t waste your money on an external gate (you don’t need new turbo’s) and you certainly don’t need external gates, they will grant you no power gains for your application, only some wank factor when you pop the hood or drive on the limittah. Plus their illegal because they vent exhaust gasses to the atmosphere

Twin filters, sure I guess, but try loose the twin MAF’s and perhaps streamline it, let it suck as much air as possible. You could loose power in air restrictions here, more than you would gain with some of your other proposed mods. If you don;t loose the MAF get the 300zx 70mm MAF X2.

ECU – I’d go a MOTEC.

Now go forth and build this monster….

Monster Hp Is N1 block , Big $$$ crank and so on, so go easy.
No extreme hp engine is stock block, the N1 block new still available ex Japan and local.
Frankly The last guy Dune is giving you alot of good advise so take it on board.
No one here is as keen as me to see you finished, grinning from ear to ear as me, as I drive both these you intend to Hybrid GQ & R32GTR.
I sped read thread so bear with me.
I hope you remembered good sump baffles RB26 have a habit of losing oil pressure and there goes all your $$ in 1 bang.
N1 turbos or similar is the go for 300 kW, water and oil cooling is needed also.
Do not use standard ceramic turbos, as Dune pointed out, this will only end in tears if you do, guaranteed.
remote filter & oil cooler will help cooling and added capacity.
Low speed and High revs will need good air flow so extra cooling will be required also, guaranteed.
The list is endless so I'm stopping here.
Frankly I've pondered this myself.
Recon RB has pretty good low torque considering size R32 =1500kg and gearing of gtr.
dont forget gtr good for over 250kph so gear that down to low gq ratios and F###@@#@
low down gearing to spin up turbos you should be busy and changing gears alot.
Good luck and carefull
