Looks like Petrol 3rd Gen prices are on the up!

There is always the water thing and the torque thing, Andy.

There's only 15 less torques, though they develop higher up the revs. It's not really noticeable (might be in a towing situation) because the autobox map is matched to the engine characteristics. I was surprised to find that if you're easy on the throttle it maintains lockup down to about 40mph.

Water. Well, we'll see. It's coil on plug though so waterproofing wont be too much of a problem. As I said the other day, any deeper than half way up the doors and you get close to floating and having to open the doors - and I am NOT doing that with my daily driver!

I suppose if I was going to build a Surf as a pure offroader, then I'd choose the diesel for reasons you say, but for a truck that will spend 90% of the time on the roads, the petrol IMO is a better compromise.

Ahhhh, but Mark's problems were carb based, not electrical. We are allowed to change our minds in the light of better information though

I've been thinking quite seriously about a Petrol 3rd Gen and the thing that keeps swinging me back to the 3.0 Diesel is that you can get about 160bhp and 260+ lbs/ft out of it for about £250. Another thing is that the Petrol motor really wouldn't like having 40 litres of Tesco's Vegetable oil poured into the tank which saves me about £10 on every fill-up.

My turn to be enlightened....Is this an intercooler thing?

[si tate]

Sparks don't like the damp and I assume torque is a lot less on the petrol equivalent...

... mind you, to have a free revving, tunable petrol lump, I'd happily forego a few towing torques....

can always get 'em back with a blower!!!

I don't know!!!! all this petrol/diesel lark, think i might just buy a prius.

No intercooler required although it will bump the figures up a bit more. Diesel Bob and tunit both do a box for the 1KZ-TE and quote 160 to 170bhp and 260-280lbs/ft. The Diesel Bob one is £240 and the tunit is a bit more expensive but they do good discounts.

I'd be pretty sure that the 3.0 diesel would be in 3.4 petrol performance territory with the box fitted and healthy injectors.

More power comes from more fuel - especially on a diesel, so your power and torque would come at the expense of much reduced mpg - and forget the veg oil as it doesn't have as high a specific impulse as diesel so you'd actually lose power rather than gain it.

All that money and extra fuel to get similar bhp to the cheaper to run, cheaper to buy 2.7. Worth it?

The Veg oil was just standard vs standard Andy, in which case it makes the 3.0TD cheaper to run than any of the other engines. You are correct in that the power comes from additional fuel but it does not negatively affect overall fuel consumption unless you drive on full throttle constantly. I've had a few diesel vehicles with boxes fitted and there is no noticeable reduction in fuel economy unless you cane the ar*e out of it all the time. If the additional power is used for getting up to cruising speed and overtaking, you won't feel any pressure on the wallet. You may be using more fuel for a given throttle position and engine speed but you'll be off the throttle sooner and many times this actually equates to a net increase in economy. Its a fact in many applications that aggressive acceleration to cruising speed is more economical than a gradual acceleration.

I'd argue that the 2.7 is not cheaper to run. Like for like on an A road cruise, it may be marginally cheaper. Around town (where I do almost all of my driving), definitely not.

There will be flag wavers and doom sayers for any product or idea. From personal experience, I have always found the boxes to be well worth the money and have never had a single mechanical failure related to the box in over 100k miles of driving with one fitted.

My 3rd Gen 3.0Td will have a tuning box and new injectors fitted in short order. 3.4 performance at 70% of the running costs and useable torque from very low revs sounds like a win-win to me.

Keep us posted on how it performs.

If everyone wanted the petrol one, I wouldn't have got mine for the price of a decent holiday

Will do, I think at 130k miles, the injectors will probably be past their best and they're cheap and easy to replace.

I had a Bobbox fitted. I installed it high up under the bonnet - next to the diagnostic socket. It worked well. It gave more power, in a thump/surge kind of way. However it was not waterproof. After a short wade a couple of weeks ago my surf went into limp home mode, with the check light on. After a bit of roadside faff I disconnected the Bobbox and pulled its fuse. Normal service resumed. When I got home I opened the removed box - it was sodden and corroded to buggery! If I was going to install another one I would splice it in next to the ECU to try and keep it dry. However, having had one, I would rather spend the money elsewhere.

Just my opinion.

Can I just remind everyone that we don't like Diesel Bob.

Remember, he doesn't want your custom. Boooooooo!

Well im pretty much sold on one when i comes to replace mine, shame nobody near me has one that i can test drive.
