Default 05RS Intake Manifold on 98 Legacy EJ22

So I heard that he intake manifold from a 2005 RS is the best flowing one. Will it bolt up to my EJ22?

Not if it's a 1998 EJ22.

It's a phase I motor and has a different bolt pattern for the intake manifold.

Also, the 05 is drive by wire, so you'll have to fabricate a cable stop for the throttle.

Other than that....it's a great manifold.

So which intake manifold could I bolt on that I would benefit from?

Also is the intake manifold and throttlebody from a 96 legacy EJ22 the same as my 98 legacy ej22? As I know where I can get them for cheap and i'll port them myself.

There isn't anything currently out there that will be of measurable difference. It would be different if the motor were a 99+ EJ22. At that point, you can use many different manifolds.

I suppose if you found a spare manifold, you could have it extrudehoned for some help.

The porting in the '05+ manifold is indeed huge. There is a problem that I see though. Because the ports are so much larger that the transition area is mismatched too much. There is not any way to get the port sizes close enough to get good transitional flow between a newer manifold and an older set of heads. Just my opinion here. Also, we put one on a flow bench. It did flow more air but did not have any more velocity. Which is crucial to a N/A application. Has anyone gotten hard dyno data from adding one of these manifolds yet?
