Re: lowering compression ratio for turbo

[Jeff Toomasson <jtoomasson@yahoo.com>]

I have 9A 2.0 block (mileage to low to justify ripping
it apart) sitting in my carport begging me to do
something, anything with it. Need to sell my M3 for
funds before I can afford to do anything though.

I'm just still struggling with the dilemma of going
with the "traditional" bolt-on's or do something
that'll turn heads. The idea of having to feel my way
through tuning a turbo'ed system makes me slightly
uneasy - it's supposed to be a daily driver....(Please
pardon the whine)...

Happy Turkey Day, everyone!  JT
