DIY: K20/K24 into 2001+ Civic **Updated 4/20/2008**

xproductionz · 09-08-2005

As i go along let me know if i missed anything so i can add it in
Also if anyone has some pics i can add then that would help too

**note- this is for anyone.. im not on here everyday. So if you need help or something im on my site everyday XproductionZ.com :: Ver. 3.0 on the forums if you need it.

UPDATE 1/7/2007 (Slightly Updated)

**also note that the same thing applies to people who do the k24 swap. Just remember that if you use a k24 that the passenger side mount is different from the k20 passenger mount. If you already have a k20 in your car and wish to use a k24. Hasport and i think Hybrid can supply only the k24 passenger mount so that way it sits the motor lower so it can fit in our cars

**If you need a relay to do the the wire harness for the O2 sensor i can get those for you

Mods done to the car in the swap
Hondata
Type S manifold and Base TB.. (took out the dual intake runners)
Megan Race headers
Megan Race Downpipe
Custom 2.5 Piping
Megan Race Exhaust
Custom 3in Intake

and the Dyno

UPDATE 4/29/07 - Read Below

An RBC manifold on a K20 and/or K24 using Hasport mounts will fit the 01-05 chassis. Just did the swap yesterday. Took out the K20a and put in a K24.

However you will need to trim away at the upper radiator support area to make it fit. You have to trim about 3/4 an inch away just to make it clear.

Minor UPDATE 11/24/07:

For those of you who use a relay other than the type listed in the DIY. There are aftermarket relays but they all use a universal number to identify the pins..

Some of you might remember this image of the relay pins..

Heres is what each number stands for:

1 - 30
2 - 87
3 - 86
4 - 87a
5 - 85\

updated with more k20 specs found on the net

and i also put in a story(article) that discusses the whole theory and idea behind the k20 motors and swaps. In one of the sections the author even talks about our EM cars and the swapping of the k20's into it

xproductionz · 09-11-2005

updated again today. Now it goes more into the engine bay prepping.. i stopped at the radiator fan wiring
