I did a quick look at the Hondas, and the small and mid size cars did
not seem to even offer a v6. Just a 4 and a turbo 4. I don't care for
the turbos on a street car.


Why?
My last car was a 2.0 turbo. I was quite happy with the performance.

Today's turbos are a far cry from the Corvair or Jetfire of the
sixties, or the old SVO Mustang!!! Rven the Saab turbos of rhe
seventies and eighties were very crude by today's standards and were
considered consumeables. Today's turbos should last the life of the
car

I admitt that I do not understand the whole thoughs on the street
turbos. Back in the 1960's many engines had a compression ratio of
about 10:1 or more. Then came the air polution acts and the compression
ratios were droped to well under that. I know there is a practical
limit on the compression ratio for engines.

Wouldn't the turbos on the low compression engines be just about like
going back up on the compression ratio ? Forcing more air into the
engine is all that the turbo does doesn't it ?

My thinking is the turbo is just more junk added to an engine to beat
the polution rules.

All this is for stree cars and not ones ran on the tracks where even
with the high compression ratios are not good enough to produce the
maximum power.

Not checking out the turbos, do they require the higher octain (higher
price ) fuel ?

While not really the case, my thoughts are like one I read years ago in
that there is no subistute for cubic inches.



Turn out there is a substitute for cubic inches. My 2.0 engine is a
mere 122 cubic inches. Puts out close to the same power as the old 283
Chevy block. Remember when it was a big deal to get 1 hp for 1 cu in?
My Sonata was 245 hp.

My Genesis is 232 cu in (3.8 ltr) and puts out 311 HP with no turbo but
you can get a 3.3 liter turbo with 365.

In spite of pushing the compression up, turbos today run just fine on
regular 87 octane and regular oil. They don't have the turbo lag of the
past. I had a '83 Mercedes with the turbo diesel. It took a few
seconds for the turbo kick in. I live on a holl and it was an annoyance
when I turned out of my driveway to go up the hill.
