the engine is not the same.a base rsx comes with the K20A3specsisplacement: 1998 cc Compression: 9.8:1 Power: 155|hp(115 kW) @ 6500 rpm Torque: 141 lb·ft (191 N·m)* (191 N·m) @ 4000 rpm Redline: 6800 rpm a 2005 type s rsx comes with the K20Z1specsisplacement: 1998 cc Compression: 11.0:1 Power: 210 hp (154 kW) @ 7800 rpm (SAE net J1349 Rev 8/04) Torque: 143 ft·lbf (194 N·m) @ 7000 rpm (SAE net J1349 Rev 8/04) Redline: 8100 rpm they are not the same at all. they are from the same engine family but design/parts are not the same.the intake manifold is diff also the rsx come with a plastic one and the type is is alum i think.

engines not the same

Intake is different, exhaust is different, engine compression is different.

you mean base model vs the type s model? base model is k20a3.. its for fuel economy.. it has 5 gear ratios for the transmission. when you engage in vtec its not that must improvement.. the cam lobes are not made for higher lift. the manifold is for daily driving and saving gas.. headers are different.. now the type S is made for racing.. I have a k20a2 or type s motor right now in y 97 civic hatch.. its amazing! just go with type s man.. you wont regret it.. plus it responds better to bolt ons like air intake, manifold, headers, etc..
