I did not know that, thanks for the correction. Every day is a school day! I figured that the 500cc drop was done by losing a pot and it was the same 5 pot 2.5 whiteblock in the 850/V70.

Any ideas as to why the 2.5 models were made/what market they were aimed at? It seems like a lot of effort to re-engineer the six cylinder engine with smaller bores, longer rods and shorter stroke when the 3.0 came first and the 2.5 produces 30hp less and seems to return similar fuel figures.

Not 100% sure really. The 2.5 was introduced in model year 1995 and seemed to be more commonly mated to the manual box.

Probably Italy and/or Japan or similar countries with tax-breaks for having engines under a certain size. Something in the back of my mind says it around 2.8L at the time the 960 was made that made for an ŁOUCH tax bracket in Italy.

In such a big car it is the torque figures that really give that feel and the turbo has some major torque when it gets turning.

You know its quick when the biggest problem with accelerating is that the g forces give you neck ache...lol
Maybe so but my 960 is a killer at overtaking the 50 to 80+ is epic and leaves many behind wondering what the green brick shaped blur was and the straight six is smooth..

IMO they were introduced for the caravanners, especially as it was offered with the M90 'box, and everyone knows the slushmatic seems to poo itself if towing anything heavy (like a caravan) up a long incline.

Slightly sneakily though, Volvo fitted the ridiculous 4.1:1 diff, meaning 0-60 times weren't too much slower than the 3.0's, however at the expense of being at 3,000rpm at 70mph.
For comparison, my 940 Turbo would sit at 70 at a more reasonable 2,250rpm.

Cheers

It actually has two listed

B230ET
182hp @ 5800rpm
260Nm @ 3420rpm
9:1 compression
98/4 star octane required
Motronic

B230FT
156hp @ 4800rpm
242Nm @ 3300rpm
8.7:1 compression
LH-Jetronic
91 unleaded

I assume the FT would be LH2.2 and I don't think we got it over here.

It also says at the bottom that all Volvo engines can be ran on unleaded and that all Volvos that can run on it have green fuel caps.
You now know the B230FT was sold here Luke!

Everyone knows though the FT (and FK!) should be run at 12-13psi for a nice ~185bhp

What's under the bonnet of your blue 765 Turbo Luke? Does it have a cat and a Lambda sensor?
