Fw: Reference to turbos....

[Mihnea Cotet]

Agreed about the wear factor that the turbo engines have and that might be
higher than on NA engines, but man, most of the I5t's I know of have higher
mileage than the i5NAs I know and they also use less oil, so which one is
stronger???
His point might be true about the fragile Bimmer engines but with Audi's
engines I don't think this could be true as they are pretty
overengineered...Ever seen a 3.2l M3's headgasket after hitting the
rev-limiter a *single* time with a cold engine? I can tell you for I've
seen one once, it doesn't look good anymore :-))) And I know hitting the
rev-limiter on a cold engine but at least on the 20vt I5 engines it's
absolutely harmless... a friend of mine has been doing this for over
150.000 miles with his 3B converted 90q20v (and it's also MTM chipped for
286 HP) and he never had a single head gasket failure, and he always pulls
in 1st and 2nd until the rev limiter, even with a stone cold engine that
has been sitting for 6 hours in -10°C temps... so the point here is that
the bimmer engines and Audi engines aren't comparable from a
reliability/strength point of view...

Just my 0.02 Euro,


Mihnea, happy 20vt driver
