well lets see...
2000+ eclipse GS=2.4-liter SOHC 16-valve 4-cylinder engine with 147-horsepower
2000+ eclipse GT=3.0-liter SOHC 24-valve V6 with 200-horsepower
I'd say there's a slight difference. </sarcasm>
there's no way ur gonna beat an eclipse GT with intake and exhaust unless it's automatic and/or u have more mods than just i/h/e. Especially considering that the GT eclipses also have more torque than the SE-R, unlike the RSX-S
The GT eclipse was actually the car I wanted to get but it was just a little outta my price range and insurance was too high, so a good deal came up with the Spec and I grabbed it
but I can't complain...i love this car!
And back to the topic, the only differences performance wise between the base SE-R and Spec is a free flow exhaust on the Spec to give it that extra 10hp, and 6-speed transmission. Now granted the 6-speed is very nice, if the 2 cars were to get an identical exhaust system (header and catback) they should be identical in power, right? then it's all up to the guy driving the 6speed to know how to drive it.............
