NO they will not fit. The heads have to be the same model as the intake manifold. If you put wrx heads on your car, then you could use a wrx intake manifold.

A 99-01 GC8 intake manifold should be ok but double check on that.

IIRC, an SOHC manifold should work.

You need to decide which injectors you want to use. 99 manifold will only fit 99 injectors. WRX manifold will not fit 2000-on injectors. They will fit 99 injectors by just widening the top of the injector pocket. THe WRX manifold is larger than the RS intake ports, so is not really a long term solution to begin with.

You need to purchase a 2000-2004 NA 2.5 manifold to use the more common injectors. THe plastic manifold will work, but will need a few things to work.

Greg

I have a 2001 2.5RS manifold extra at home. If someone needs it, please let me know. I have idle control motor, fuel rails and injectors too.
