sacrilegious? yes, but one hell of an entertaining read

my track car is a nissan 240sx with a cammed LS6 motor. You can't beat the feeling of NA 470whp/430wtq
They are wonderful engine but I wouldn't put one in my 997

 

I actually think that 996 C4S with the LS3 is an amazing project. If it weren't for the fact that I live in California and it would take an act of God to get it past a smog inspection here, I'd be tempted to embark on a project like that. Not with my 997 mind you - but with an older 996 that can be acquired cheaply.
