Sti Spec C Type RA-R
#2
It doesn't say anything about a different throttle body, unless I've missed it. Like the S204, the RA-R comes with the larger STI turbo inlet pipe (and the larger VF42 turbo). When they say different ECU, I would imagine that it is physically the same ECU but with a bespoke map as the cars are running more bhp out of the factory than standard.
SFS Performance do the largest turbo inlet pipe, I've seen a Samco, STI and SFS pipe in the flesh together and the SFS is definitely larger of all three. Got one fitted to mine.
