Outer Limits 4x4 Board

looking at buying a duel cab just after info on the 3.4 v6 petrol and the turbo diesel just want fuel econ figgers as a 500klm day trips would not be out of the question and also how do the turbo diesel engins go on road keep up with trafic etc compared to the v6 petrol

also will only be looking at running 31inch rubber




sorry if this is been brought up before i have searched just direct me to the links

I can help you on economy of the 3.4 v6 petrol with a set of extractors fitted. I get over 500km out of every tank. Apprently without the extractors its a struggle to get more than 400 out of every tank. So if you want the v6 one budget in a set of extractors and a matching exhaust system.

My friends 3L diesel in his 2000 model gets him over 600km out of every tank its on 32's but other than that its standard. His isnt turbo diesel though so its pretty damn slow.

cheers for the info so what size tires do u run to get 500km from a tank

other than the exhaust and extractors my car is still normal mate so its running a set of 31x10.5's Im sure the economy will be going out the window once ive fitted the SAS kit and 35's but for now its good.

just FYI my old 2000 model with the 2.7L 4cyl had 33's and used to get 430-450 out of a tank and all that had was extractors as well. I got about an extra 50 km's out of the tank when i fitted the extractors. And heaps better performance.

In my opinion every car should come factory with decent extractors they improve fuel economy and performance. And who doesnt want that??

how did the 2.7 go on the beach sand dunes etc i bet the v6 shits on it, i had the 2.4 petty running 33s so im after sumthing with a bit more go im thinking of selling the 33s for 31s cause to affaired to run them with the ifs

the 2.7's go better than you'd imagine, lots of torque, i cannot comment as i did not put extractors on my 3rz, but from having a good look at the standard 3rz headers, they looked like toyota had put a fair bit of work into them, they are not your average junk cast headers.

Throw some 4.5's or 4.88s in the diffs when you get 35's and economy will be near where it was.

The 3l with a turbo fitted would get a good improvement in economy again.

What are the k's based on, highway, round town, or a bit of both?

2.7 was mint mate very torquey it will pull itself up anything. Beach no worries rocks/mud anything i tried no worries in fact the only thing i didnt like about it was on 33's at 110km on a pretty un aerodynamic vehicle (mine had 3 inch bodylift and 2 inch suspension plus the 33's plus with my quad and another mx bike on the back and camping stuff) it sucked trying to over take people.

The 2.7 i believe is under-rated its very very tough as i say it just sucked on the highway when it comes to off road it was as good as anything else out there. And mine had 230km's so it wasnt low km's and still going strong.

Yes the v6 is better its got more power and im hoping to supercharge mine one day to produce even more but dont discount the 2.7's they are tough little engines. Id choose one over the diesel engines anyday.


:Edit due to new post: ( Dont forget both the 3.4 and 2.7 were fitted with extractors before extractors on my 3.4 i dont know because they were the first thing to go on and the 2.7 before extractors take away about 50kms per tank) The diesel is standard - these are just mine and my friends car im doing camparo's on perhaps other people have more to add??

the 2.7 highway was 400ish
around town 450ish ( dont ask my why im guessing the aerodynamics of a brick)

the 3.4 Highway over 500
Around town over 500 ( cant be more specific sorry)

the 3L diesel highway 650ish
around town 600ish

hope this helps

( Oh and i bought 4.88's when i bought the kit so im hoping your right - And if you think your 2.7 is torquey now fit some extractors!! I think mine cost 200 dollars i fitted them in about 2-3 hours and it revs like nothing else once your done i left the normal exhaust in place and still got significant gains in midrange performance)
