Type R's don't have a secondary butterfly.
JDM b18c has no secondary butterfly and VTEC comes on at 5800.
no higher, no lower.
This is the case with AUDM vtir & JDM Sir-G.
They both have the dual stage intake manifold.
Vtec comes on at 4200(I think) and Secondaries at 5k+.
REPEAT - TYPE R'S DON'T HAVE DUAL STAGE INTAKE!!!!!!
then you don't have a type R motor.
sorry.
