I just picked up a 94 Civic CX hatch to swap my K20 in(sheds tear over totalled RSX-S ) and I need a little help in knowledge before attempting the swap. Just a list of questions I've been pondering over for awhile. I will update post if anything else comes to mind.

1. Do I need to use the RSX subframe in the swap? I remember hearing somewhere that I would, but can't remember the source at this time.

2. Would I be able to retain the use of the immobilizer? I have all the part necessary from my RSX, as long as the wiring harness supports it, would it be a possibility?

3. Has someone made a harness that supports the electric reverse lockout? If not, is it possible?

4. To those people who've done their swap already, what did you do for piping after the header? And what header did you use? Cat/Catless?

5. I really liked the post on intakes and the pic's with the Prototype Racing velocity stack. The stack though is just the straight section of pipe, correct? If so, would anyone be able to suggest a good place to look for similar aluminum piping? Or could I just get two vel. stacks and mandrel bend one of them?

I had another question which I can't remember right now, but I'll post up later if I can remember it.

no to 1, just need new mounts. im not sure if you can use the immobilizer, but you will need kpro. hasport has released a header for k swapped cars, dtr or you can mod a tsx header. if you have a exhaust on it, it must be shortened wether use a cat or not, even shorter for use of a cat. dont use your stock civic piping though. you can just buy a short ram for a civic and it should work aslong as its short and straight. the other ?'s i cant help you with. chime in...

Thanks for the response k20spooner. I still haven't taken the K20 out of the RSX yet, and I need to pick up another throttle body for it. Other than that it's just going to be getting the parts necessary and finding a place to do it. Thinking I might have to card the parts(I hate plastic!) and pay it off when tax return time rolls around( to being a student). Hopefully the swap will go relatively painless and be done by spring.

1. You do not need the RSX subframe.

2. You can use the immobilizer from the RSX you just need to wire everything in. Let me know if you need help with this.

3. It is possible to wire it in.

4. We used a comptech header with a custom flange and no cat.

5. I didn’t see this post. Where was it again?

Let us know if you have any other questions.

Thanks,

Will, the topic title is "Re: K20a Intake?". There's some pics of the intake(gray in color) a few posts down.

nope sorry - what you are referring to is the intake piping NOT the velocity stack. as I stated in that thread...the piping was custom made by the shop that installed it

the velocity stack looks like just a horn - its the piece on the right

here is what what it looks like attached to the intake tubing

you can basically buy a large sized K&N filter that will fit over the stack

what is an immobilizer???

 

[hybrid racing]

What is the Immobilizer?

Honda has installed a new immobilizer (type 3) in there 02+ model cars. The immobilizer system has 4 parts: The Key, Immobilizer system indicator, Immobilizer control unit, and ECM. All of these must be in place for the car to crank. The key is coded with a transponder id code. The immobilizer control unit is located around the ignition switch. It uses an electromagnetic induction to power the transponder in the key. The key then sends its ID code to the control unit. Once received it is matched against the code in the receivers’ memory. If the code matches, the immobilizer will send a coded signal to the ECM allowing the car to crank. If it does not match it will not send a code and the car will not crank.
