Hi guys, i got a 05 Honda CIvic SI EP3 that has rod knock currently so i'm assuming it needs a new engine. From my research its a K20A engine, I found a place online that sells JDM engines that they claim have no more than 65k miles on them, its $600 shipped to my door, i was wondering if anyone had any experiences with buying engines online? this is the direct link to the product here , would i be able to drop this into my car as a plug n play?

thank you

Should be a plug and play, check their reviews, if your satisfied with them, go for it.

Looking it up, it appears the K20A was JDM only, the 2002-2005 Civic Si appears to have received the K20A3, significantly less power. your ECU will not run the JDM K20A properly. The compression difference will be more than the ECU can handle and the fuel maps are built for the 9.8:1 CR not the 11.5:1 high performance engine. Even your intake manifold isn't tuned for the JDM engine.

Hello, thanks for the reply, i'm not sure if you clicked the hyper link, but the engine says 02-04 ACURA RSX (BASE) 02-05 HONDA CIVIC Si 2.0L i-VTEC ENGINE JDM K20A K20A3. I dont believe its the type R engine you're talking about. but let me know if i'n wrong.

Thank you

I cant find any reviews on them, do you know of any website that sells JDM engines and have good reviews? i was not able to find any.

Thanks

Yeah, seems wikipedia may be incomplete. Your site also has the K20A type R and it looks like my K20Z3 in design while your K20A looks like the CRV K24 motor so is very likely your replacement motor.

I also noticed they have a B20 listed cheap and state low compression. So it appears they compression test and will indicate if it's low in the ad.
