The Z is definitely a very nice looking car. I did the basic mods I/HFC/CBE and tune. The car is definitely faster and sounds better then before but still not Corvette territory. I spent about
$2,500.00 for all the mods which includes the cost of installing the parts as well. I haven't been to the track since completing the mods but it should be good for high 12s.
I thought about FI but I am just going to enjoy what I have and buy a used Corvette LS3 Z51 6M in a few years when the Z has about 100k miles on it I am at 30k right now.
Now the Corvette responds very well to mods. I was actually cross shopping the 2009 C6 Z51 and the 370z Sport/Touring some times I think I should have coughed up the extra 5-6k for the C6. It's ridiculous how much HP they put out.
