i wanted to know, i kknow the tail lights are diffrent what else?

 

Your kidding?

 

Ok, here's one because im in a good mood.

The steering wheel in an S4 has two spokes and the S5 has three

 

not kiddin, i ask cuz i wanted to learn i just got in to the rx7 scene i used to build hondas before this.

 

The shifter on the S4 has a bigger thread than the S5 shifter.( I think someone is Going to Mention "that word' again)..so..let me start....S.

 

e

The engine is different.

Pay it forward.

Also go to the bottom of the page on this topic. I see 3 separate topics about the differences.

 

a

The trim on an S4 is black, trim on an S5.... body color

 

The taillights are different.

 

rotor weights giving higher redline, AFM, pressure sensors, injector plug design, VDI on N/A's, 6 port actuators move different directions, body side moldings, front and rear bumpers, mirrors, turn signal controls, gauges, thermostat housing, radio surround, shifter, shifter surround, height of the turbo spoiler, umm, let me see, i know theres more.....

Oh yea, Turn signal lenses, foglights, wheel designs, and i think thats it....

You could try reading the FAQ though, or even the FSM in the archive...

 

not to mention 10 blades on the S5 fan, and only 8 on the S4. The radiator is different, and even more stuff.

 

Ball joints on the S4 are removable, S5's are not

muffler bearings

 

Interior radio/vent/logicon surround bezel is different, S5 has round gauges in the instrument cluster where the S4's are more..erm..triangular.

 

s4 is 86 to 88 s5 is 89 to 91, just thought i would throw that out there...
also i think the resivoir for the turn signal fluid is bigger in the s5....

 

s5 has a supercharged option from the factory, s4 is only turbocharged option

 

Don't forget the turbonium and the blinker fluid.
