Everything You Need to go R18 to K Series (K20 or K24)

Everything You Need to go R18 to K Series By Brian Gillespie and Aaron Gaghagen Looking for a quick list of parts you'll need to do a K swap in your R18 powers 8th Gen Civic? Look no further. These are the parts you'll need if you're swapping your R18 for an 8th gen Si engine and transmission. 06-11 Civic Si exhaust header 06-11 Civic Si catalytic converter (to be legal) 06-11 Civic Si or better exhaust (so you aren't limiting the engine) 06-11 Civic Si radiator hoses 06-11 Civic Si heater hoses 06-11 Civic Si air fuel sensor and secondary O2 sensor 06-11 Civic Si ECU 06-11 Civic Si engine wire harness and charge harness 06-11 Civic Si shift cables 06-11 Civic Si intake air tube, airbox and MAF sensor We opted to installed a K24A2 from a TSX so we also grabbed these parts. Some needed more than others. 06-11 Civic Si intake manifold (optional) 06-11 Civic Si throttle body (optional) Hondata FlashPro (to get full potential of the K24A2) 06-11 Civic Si oil pan (this is where the rear mount attaches) The deeper than normal K-series oil pan found the 8th gen Civic Si needs a deeper sump. One option is to modified an 8th gen Si oil pump to clear the K24 crank pulley. It can be used with the K24 oil pump chain, guide and tensioner. Some people have gone without doing the pump with the deeper sump, but I don't recommend that, especially if you plan to bring the car out the track. We opted to use a JDM FD2 oil pump with chain, guide and tensioner. Lastly, there a couple of other custom parts we used. We opted to keep the hydraulic power steering so we had a high pressure power steering hose made and used a TSX PS pump with it. Also we used some PS fluid resistant bulk hose to make a feed line for the pump. To get the Si ECU to work with the non-Si cabin harness we made an adapter harness. Parts to make the adapter harness were purchased from Corsa Technic. For more information on building your adapter harness, check out this video. /watch/Usl1xpADSMzD1 Don't forget that you will need to have a dealership reflash your ECU and MICU to get your key and car to play nicely with your new swap. It's kind of a pain, but it also gives you an extra layer of security to not allow someone to start your car without the real key. Watched all the videos and still have a question about this swap?
