I am considering the purchase of a dedicated event car to take to HPDEs, Time Trials and Hillclimbs. I will most likely contest a Street Prepared class during the timed events, but have not made a final decision. The value represented by the 4th Gen F-body is attractive. I have yet to uncover a single source buyer's that details perfomance affecting year-over-year changes and options. Is there such a thing? Any links or attempts at putting together a brief one here would be appreciated.

Well, this is as good of a place as any to piece together a buyers guide. I'll start with some changes that I know, and some that we need years for (when they did it), as we get that info, we can build it into a sticky or at least a concise post.

1993 uses an eprom, not a flash programmable memory.

1996 (was it 1996?) was the first year of OBD II, some LT1 guys are switching back to OBD I computers.

1998 is the first year of the LS1.

2001 and 2002 LS1 cars got a smaller cam but also have the LS6 intake from the Z06. Some claim that those years dyno stronger, but mine didn't. They also have no EGR valve and plumbing on those years.

SS's (from all years as I remember) had the 32mm front sway bar (you'll want a 35mm anyway).

Somewhere they swapped from an Auburn limited slip to the Torsen (I'm thinking it was 1998, but I may be very wrong).

If anyone sees any errors in that, let me know.
