What patrol for max power ?

[muddylux]

Looking at getting a gu Patrol, but am undecided on what engine to get.

I want Max power, the more the better, and I don't mind modding it too the max, but i'd like to keep it sane at the bowser... say economy of around 15l per 100km in most conditions.

I don't want to do a engine transplant, or go LPG only set up.

What engine would give the best base to start from ?

And from what year GU patrol currently available ?



Hopefuly crossing over from the Toyota world to Nissan.

4.8 petrol is what u want, not the most economical engine around but with a big turbo and a decent amount of money thrown at it, there really isn't a limit to what they can make. Just search turbo 4.8 patrol into YouTube and u will see what I mean. I imagine if driven gently u could get average economy, but u can't have both. But like I said, an insane engine when built to the eyeballs

Not to sure when they first came in but I imagine around the 2004 mark? Mostly autos, but some rare manuals.

Hey mate,
Max power and 15ltrs/100km don't go together....
I get around 13 to 15 around town in my GQ TD42 and 18 on fraser, however, I took my GQ down the quarter mile last year and it ran 23 seconds at 92mph...

A GU was there, he got 16 seconds but he said he is lucky to get 18ltrs/100km around town, and on the beach 30ltrs/100km is not unheard of.

Cheers.

If you planning on big power from the tb48 enginened patrol would recomend you go a manual the 5speed auto's don't seem to take a lot of abuse. The 4 speed autos can be tweaked to take big power.

......... say economy of around 15l per 100km in most conditions.

How long is a piece of string. I've seen 13l per 100 and 35 litres per 100 out of the same Diesel engine driven different ways.
15 per 100 in a 2.5 ton car is only achievable (in average driving conditions) with a diesel or by boring people.

Air + fuel = horsepower. you can't have horsepower without burning fuel.
There is a bit more power per litre of diesel than in a litre of petrol.

Big horsepower and small weight = good performance.
Your weight is pretty much fixed at 2.2 tons and upwards with a patrol LWB and a shorty isn't much better. Fully kitted out for touring with a winch barwork two spares long range tank dual batteries fridge recovery gear etc etc can easily put you over 3 tons.

Max power without going insane? depends on your definition of sane.
HERE ARE YOUR FACTORY GU ENGINE OPTIONS
TB48 twin overhead cam 24 valve petrol 4.8 - 1000hp can be got from the 4.8 with a stroker kit and turbo and all the fruit. Pick of the lot for power, potentially the worst for fuel consumption for the same reason.

TD42 old school side cam 12 valve 4.2 diesel both turbo and NA, these cost a bloody fortune in a GU for good reason. Can be tuned for 300hp at the wheels with a TD42 with fuel pump work big intercooling and decent turbo. If you buy a naturally asprirated version intending to put a turbo on you cant get as much power as a proper turbo motor due to the weaker pistons mostly. These go forever, a few have done a million km if looked after. Servicing costs are high, 11.5 litres of oil and two oil filters every 5000km. 300HP will cost a bit to achieve - about the same cost as an LS-1 chev conversion.

ZD30 (3 litre modern turbo diesel) go allright but forget about improving them much. Have a habit of self destructing but there are simple cheap mods to make them reliable. very affordable but not exciting.

RD28 2.8 litre sohc non crossflow 6 cylinder turbo diesel...well its under 3 litres of old technology hauling 2 and a half tons.. you can get more out of the ZD30. Very cheap and go ok with some minor mods, even less exciting. run a smaller gearbox than the rest.

TB45 4.5 litre petrol 12 valve, pushrod motor. not as good as the 4.8 but a lot cheaper. lower tech design. driven in exactly the same way you would use slightly less fuel in a 4.8

TB42 petrol. 4.2 litres, average. cheap. reliable. common.

THE MOST COMMON ENGINE CONVERSIONS:
All of these require engineering which adds a bit to the cost, all of these I think you are better off getting already done. They don't add as much as you think to resale.
GM 6.5 v8 NA diesel. Limited usefulness. good for boring people with really big horse floats. Spend half the cost of one of these conversions on a TD42 and you can not only run rings around one, you can do circle work in 4-high around one. But for certain limited applications they are the goods.

GM 6.2 turbo diesel. a bit better. still not worth it IMO unless you're towing at max GCM more than 50% of the time. in which case you should have bought a small truck.

GM 6.5 diesel with bullet supercharger - immense cool factor. go allright, a bit expensive if you consider $ per horsepower. If the cool factor is important you dont care what it costs.

6.6 litre LBZ duramax turbo diesel, now were talking, still pretty rare and take a lot of work. they absolutely hammer chipping and tuning you can have a reliable and economical 400 horsepower. conversion will cost at least 40k to do properly. If anyone has one they wont be selling it.

LS-1 chev petrol 5.7 litre. go pretty good. professional conversion people have done so many they are as good as factory. but look out for poorly done ones. cost about $10k to $15k to do right. SOme have the GM auto. dont touch unless the auto has been beefed up. Parts readily available. Make a really nice car out of it because the motor isnt working so hard to get it moving. plenty of performance options off the shelf for this engine.

LS-2 chev. 6 litre petrol. better than above. not so many done as the ls-1 so just look closely at the wiring etc.

Thanks MarkH for all the info.

Looks like I'll go a 2005 series IV manual with a 3.0l and chip it for a daily driver, as I don't want a big fuel bill every week...... Nar fark that sheit, i'll just grab a 4.8 and bomb it for at least 300 atw's

HA HA HA.Maby you could just go the turbo boost like knight rider!
Max power here we come!

[WarioGF]

For those of you interested in when the 4.8 petrol motor started, I don't know the definative answer to the question but I have a GU Ti 4.8 built in December 2002.

[roberts]

i wouldnt buy a gu unless it had a 4.2

HA HA HA.Maby you could just go the turbo boost like knight rider!

Homer Simpson: Kids: there's three ways to do things; the right way, the wrong way and the Max Power way!
Bart: Isn't that the wrong way?
Homer Simpson: Yeah, but faster!

Hmm. Didn't know the simpsons knew about max powering 4.8's in 1999

[roberts]

its old gregs mangina

I would and did! Got a 4.8 put it on injected gas and can't get the keys off the wife... She tells me its nice to drive and i know it changes gears smooth i just don't get to steer it.
