Re: 2000 vs 2001 3.8 Firebird

i really have no idea, the only thing i can really think of is the different style exhaust manifolds, but im not sure when they switched them

Re: 2000 vs 2001 3.8 Firebird

Re: 2000 vs 2001 3.8 Firebird

well, i think its just a number they put on it to make it look better. like how the tubular manifolds would give more hp, but the same 200hp number is kept til the end.

More weight due to more standard options maybe?

This EPA thing is never accurate. When I bought my Firebird the EPA reading was similar to a V8.

The same thing goes for my 89. The EPA was exactly the same as the V8.
