Well here is the Race Elite RBC swap by RCautoworks for the 2012-2015 Honda Civic Si.
K-Tuned RBC swap Cold air intake
K-Tuned RBC swap coolant delete
K-Tuned ZDX TB adapter with 2 map plugs
Ported TB 70mm
ZDX DBW TB
DW 550cc or Grams 550cc injectors with PNP clips (contact us for different injectors)
All hoses and hardware for install
Please note, manifold will need to be cut for the coolant adapter, this lets the RBC run at much lower temps due to no coolant flowing through the manifold resulting in more power. The nice part also, with the K-Tuned Tb adapter you will hide all hoses and wiring and map sensor under the Tb for a much cleaner look.
Make sure to also add a K-Tuned fuel rail to your order to complete the look of the RBC swap
