Hello Everyone, I have a 2015 Civic Si sedan. Im currently in the process of getting all the parts together for this build. I will post parts list along with pics and details of whats needed for the build as I go along!! I understand it has been done before but NO one has shared any concrete info with photo evidence of the process. Its Not very difficult but does require some detailed modifications! Any questions feel free to ask! I may leave somethings out but ill do my best!! Car is going to be built by a reputable mechanic and shop in my area, KBuilts Nelvin Performance in Aguada, Puerto Rico!
some of the pics used as reference belong to yadifb6 who has completed the swap thanks to him he encouraged me to start my build and share with you all along the way

First you will need a K20/k24 cylinder head preferably '06-10' k20z3 the head will need to be modified or it will leak!! Ill post pic for Reference: note use k24z7 headgasket

You Will need head studs. InlinePro makes the kit for k24z7. These are a must have!!

Another Must Have is the PRL Type-S Oil Pump swap kit! This makes the Type-S Oil pump a simple install! (I bought kit seperate from pump, Im still waiting on my 4 piston pump)

Next you will need an 8th gen Civic Si header. I chose a PLM Tri Y header (V1) it has not come in the mail yet so I cant post pic. The Header needs to be modified to fit! (Unless you want to buy a Hytech header which is a direct bolt on for the swap with no modification needed from HPD) note any 8th gen header will need to be modified
Heres a list put together of OEM parts needed!! Somethings you may not need depending if you purchased the head complete!

Heres a list and some pics for reference of what needs to be modified or changed!!
**You must use your 9th gen valve cover along with the upper timing chain guide from the 9th gen.
**The Exhaust Cam pulse plate must be used from the 9th gen so the VC can fit!
**The intake cam VTC bolt must be cut/modified in order for the 9th gen VC to fit correctly!
**You must use an 8th gen vtec solenoid the 9th gen housing is different but you have to swap out the spool valve and pressure sensor from the 9th gen!
**You can use the 9th gen fuel injectors with p2r spacers on the Rbc intake manifold, you can also use the 9th gen Throttle Body with PRL spacer for rbc manifold
