Hi:

As the topic say, Does anyone know if a STI V2 cams could be a good upgrade over the WRX V2 cams?

Are they worthy?

Thanks in advance

 

dont know the difference between duration and overlap etc, but I think the wrx has hydraulic lifters and the sti have shims, so if the cam profiles are different, then to take advantage of it you would need to change the whole valvetrain as I dont think the hydraulic setup is really suited for a more aggressive cam (higher rev limit assuming the sti cams are more aggressive if you see what I mean)

 

Regarding what I have read, the STI v2 does have hidraulic adapters, but the STI RA v2 have shims...

Maybe a interesting question should be, Is possible swap the hidraulic lash adapters for Shims? What will be neccesary to do this?

Thanks

 

STi V2 RA has Top Hat Inner Shims,different Valve Springs,Spring Seat,
Top retainer and different Codes on the Valves.
