I've been trying to learn more about Volvo since I became the owner of a new
S80 two years ago, and I'd swear that's the same thing I've heard and read
myself. D'ya suppose we BOTH got it wrong?
Mebbe. Somebody tell us. Me 'n ol' Rob may be confused here. Straighten
us out.

You still missed the point.......
(info taken from my Volvo service docs)
Volvo 960 engine: B6304F and B6304S + various derivatives over the model years. Bosch
Motronic
Volvo S80 T6 engine: B6284T Bore 81 mm, Stroke 90mm, 8.7-1 compression using ME7 ECM
remapped for turbo., CVVT added (variable valve timing on the exhaust)
Volvo S80 naturally aspirated 1999: B6304S3 similar to 960, different bosses for engine
mounts, etc.. transverse application 83mm bore, Stroke 90mm, 10.7-1 compression using ME7
ECM. CVVT (variable valve timing on the intake)
Volvo S80 naturally aspirated 2000: B6294S
I didn't say that the S80 engine wasn't a derivative of the 960 engines, that wasn't the
point. The T6 is different, with smaller displacement, don't you think there may be
something different?!?
ECU is different (ME7), intake plenum is different, ummm T6 is twin turbo, can you see
where there may be troubles in the first year of manufacture?? You should also read more
about turbo vs naturally aspirated, they decrease the bore and compression for turbo
application, we are talking forced induction here, the combustion pressures do not pose
any critical forces on engine components in any other way than a naturally aspirated
engine. ie: turbo is much lower compression, na is much higher., you're just trying to
ram more air/fuel into the cylinder for the given time that the intake valve is opened.
The Volvo S80 in 1999 had a very high rate of electrical failures, some of which included
engine control management, it also uses drive by wire technology.
Also here is a brief excerpt from Brickboard about the new B6284T and other S80 engines
compared to what your car has:
"A large number of components are new compared to previous version of this engine while
visually these engines are almost identical about 90% of the main components are new."

My single point was, how could you not believe that a 1999 S80 T6 could not have
problems?!? hesitation?!?! missing?!?You should re-read the post I made before you hit
"reply group" next time.. hmmm, you're quite ignorant to think that a car with so many
upgrades since your 1993 960 would contain the same electronics as the S80, does the
B6304F have variable valve timing in your 960? ummm, I don't think so, does it have drive
by wire? also, no, I am sure it doesn't. I do know however, that with some mods, the T6
engine can fit into a 960.
We aren't comparing apples to apples here, we are comparing the S80 which is a much
different car than your 960, just as much as the 960 is quite different in many respects
to my '87 760 (chassis wise, the engines are completely different).
Anyhow, I've made my point, you should do some more research before you make incorrect and
uneducated statements, time to move on to other posts that make more sense.
