I said that if you had a long enough track the S2000 would eventually catch up to the Firebird, not that it would walk past it.
Well, its been said in a later post but I'll add some factual information to this post. All LS1 powered F-bodies are electronically limited to 168mph. Thats right, they are LIMITED to 168mph. Top speed is slightly higher than that. The speed rating is in place due to the tires maximum speed rating.
I recently started buying parts for my GTA. So far I have the induction, cam, and exhaust sitting in boxes waiting for the last parts to arrive. The last part are the heads which I haven't bought yet because I'm still shopping around. I'm looking at some Iron Lightning 180cc heads that flow 268cfm on the intake and 194cfm on the exhaust, and leave plenty of room for porting. The Dyno 2000 simulations are showing roughly 400hp @ 5,500rpm and 486lb/ft @ 3,750rpm with an upgraded tuned port induction. With a tunnel ram the numbers shoot to 440hp and about 460lb/ft torque at the crank.
I don't trust my transmission to stand behind such a monster so I'll have to do something about that when I put the package on my car.
