2.3 Ho Exhaust Manifold

[violentrapture]

Found a HO exhaust manifold - will this go on the 2.4L, and is there any gain to be had from doing it if so?

You might have a problem routing that around the steering rack on the car. I know most of the cars with the Quad4 HO (except the rare Cutlass Supremes) have the rack mounted on the firewall, where the Alero's is mounted to the cradle. It's definitely a tight fit to interchange the V6 manifolds between the two platforms (been there done that). I don't know about the 4-cylinders, It could be a potential problem. Also, if your car has EGR, this manifold will not support it. (that is, if it will even bolt up?)

What about this - does it actually help like it says?
