I figured there is probably a need for one of these here. Plus it'll cut down on my PM's
If mods deem it worthy, sticky it.
Q. What motor will fit in my 2001-04 Civic?
A. As of right now mounts are available for the K20 (A2 - RSX-S, A3 - SI, A - DC5 Type R, Civic Type R). Hasport is working on mounts for the K24 (CRV, TSX, Accord). They might also do mounts for the B series.
Q. Where can i find a motor?
A. Look around salavage yards, salavage yard websites, ebay, motor importer websites, k20's don't seem very hard to find anymore.
Q. Where can i buy the mounts?
A.

Q. What parts will i need for the swap?
A.

Q. What has to be modified to work with my car?
A. If using a Civic cat-back, you have to have a exhaust shop modify the mid-pipe. If using a RSX cat-back it needs to be lengthened (once again by a exhaust shop, unless your handy with a welder).
The bracing under the hood also needs to be cut away for the power steering pump to fit . A carbon fiber hood might work to (fiber images does)
Q. Will my immobilizer still work?
A. Yes, you can have the RSX/SI ECU re-flashed to work with your key/immobilizer.
Q. What will i need to have my ECU re-flashed.
A. You have to bring the car to Acura/Honda (depending on your motor) with the motor in it, helps if you've had it running. For paper work you'll need a bill of sale of some sorts (title, receipt) and the vin number of the car you got the motor from. Acura/Honda will run a check to make sure the motor isn't stolen.
Q. Can I put the RSX 5 lug brakes on my car?
A. Yes, you’ll need a few things off the RSX to do so.
For the front you’ll need the RSX struts, the knuckles won’t bolt up to the Civic struts.
The ABS sensors from the RSX, the Civics won’t fit (found that out the hard way). You'll also need the front tie rod ends off the RSX.
For the rear you’ll need the e-brake cables from the RSX, the rear brake lines (they unbolt in the inner fender)
Q. What axles can i use?
A. If your doin the 5 lug conversion you can use the RSX axles. If you stay 4 lug you can use SI axles.
Q. How long will the swap take?
A. Me and my friend put about 30 actual hours of work into it, it can take less time if you have everything, and have more than 2 people working on it.
Q. How much will it cost me?
A. It all depends on what you plan on doing. Motors can range between $2,000 and $7,000. Then you have to figure in the cost of new parts purchased (mounts, harness, radiator, etc.) And then labor. If you get a doner it can be cheaper because there will be alot less to buy.
I personally recommend a doner car.
Q. What shop can do the swap?
A. I'd look around for any import tuner shop that has experience in motor swaps. It should be an easy swap for experienced swappers.
Q. Can i do the swap myself.
A. If you have access to a lift and power tools yes, it can be done. I don't know if its a driveway project, but its very possible someone can, and has done it.
Q. Is this all worth it?
A. Most deffiently, i can highly vouche for it, and you can ask anyone thats done it.
Thats all the questions i can think of, if anyone has anything else to add pm me and i'll add it.
