Re: (Insider)
It appears to be a different part number. Some one would have to call
to be sure.
The funny thing is their notes regarding the 003 C30 T5 manifold when
they mention the S60R exhaust manifold being a "wall"
It is so true and ridiculous when you compare the cosworth manifolds etc
to the OEM S60R design.
Also when you then look at the stock head itself on a port flow analyzer and see how bad that is also well this is why we do what we do. The improvements that can be made are staggering, probably 30% at least
with decreased pre turbo backpressure, and lower EGT
