I bought a jdm k20a swap over the weekend, sold as a dc5. But, I dont see any indications of a dc5 motor. Looks more like a ctr? Can someone let me know what motor I have? It has rsp head stampings, rsp intake manifold

 

Wiki lists the K20Z4 as having the RSP intake manifold. Accordingly the K20Z4 is from the ‘07-‘10 EDM Civic Type R.

Hope this helps.
