Compression

Erik-
  Just don't let Jeg's forget the VW's when they are gearing up for the
Sport Compact Scene!!  (yeah, like the high-volume mail-order houses care
about a few Volkswagen owners....even with in-house lobbying)

> I am a mad scientist.  (hope I spelled that right) J/K  If the time table
goes according to plan, I will have one of the more refined 16V in the land.
And with my "connections" through work I can get pistons and what ever else
I think of built for alot less than what some of the "tuner" shops are
selling them for.  I just can't see spending a grand-two grand on forged
pistons.  It's not right.  Plus If I put this thing together like I want
maybe just maybe, Jeg's will open their eyes to the whole "Sport Compact"
scene.

up aboput 6 years ago, they figured it would pass.  Now it's crunch time and
there are, 3 people including myself that know about the little boogers. As
all of the dinosaurs call them there.  Don't get me wrong I love my Olds,
but I grew up with V-dubs.  It's a labor of of love sort of thing.  Other
wise I wouldn't sweat the details so much.  Call me crazy.  Give my Soap box
to another.
