Civic Si w/ RSX Type-R swap
Iight, I'm thinking of getting rid of my 93 del Sol and getting a 02-05 Civic Si. When I get the Civic, I want to put a K20 in it (RSX Type-R). How hard is that to do?
Thanks,
Lambert

many people have done it. id say most people go for the k20a2 swap(type s) because then you have a civic type r. i havent seen too many k20a swaps in ep3 civics. search around im sure you'll find some.

If you plan on doing the sway ... save some money and buy a K20A2 motor over the JDM K20A ... use the saved money to buy a LSD. You will come out ahead ...
A2 motors with I/H/E and a good tune are putting out similar numbers as the A with the same mods. The A2 motors are strong
It's just a waste to get the K20A unless you are all about JDM Bling

I would have to disagree because it comes with cams and higher cr. plus the fd and shorter 4th, 5th, 6th. By the time you install all the parts on to a a2 it would be the same or more. plus you can count on the reliability of honda more then anyone else in my opinion. o yeah I forgot to say that it comes with a PRC manifold which alot of people want on their a2.

lol ebay!!! haha just playing...no look around man, call a few performance shops in your city and see what they got and who they can recomend. go look on jdmshit.com etc....there r plenty of websites out there where u can find it.
To answer your 1st question, it's not hard to do the swap...all ur gonna need is some extra mods to make it fit. GOod luck with that, i hope u do it...u won't regret it.

The JDM CTR has the same K20A, I'm pretty sure... but the Euro-spec CTR has the K20A2.
The DC5 ITR is the one with the shorter tranny ratios and LSD, plus it's got the 4-2-1 header and Brembos (although the Brembo brakes might be just on the JDM version, but I'm not sure).

Re: (BarracksSi)
i dont really think there ever was a true JDM CTR seeing as how even japan got all of they're CTR's imported from Europe, to add to that im pretty sure they all came with the A2 , except for or Us poor excuse k20A3
as for motors, why not looked for the new K20Z1 from the 05-06 type-s, not only does it have the final drive gear of the DC5 ITR, but it has the intake manifold, exhaust components and intake components, very stong motor.....just my thoughts

Saw a K20A2 with I/H/E and K-Pro come within 5-6hp of K20A with similar mods on a dyno last weekend. Power wise they come very close ... go buy a thinner head gasket with the money you save and bump up the compression ratio a few points for a couple hundred bucks. Yes the tranny is a little better ... you can pick up a new DC5-R LSD for under $700. As far as final drive goes ... that is a person to person thing. Just comes down to how much you want to spend ...

Re: Civic Si w/ RSX Type-R swap (LambertdelSol)
you'll need the motor of course and an ECU to go along with it ... you can send your stock EP3 ECU to Hondata and have reflashed as a K-Pro (that would be your best option for tuning flexibility) ... you will also have to send them your key and immobilizer. You may want to get stiffer motor mounts. You'll have to do something with the shifter (forget what it is exactly, something getting cut out to get reverse to work) since you will be going to a 6-spd.
If you get the Type R motor you will need to get the Type R front sway bar in order to clear the header.
You may want to get some better axles depending on your power goals.
I think that really should be about it ... the motor should drop right in. Not sure if all the hoses are routed the same, but I am sure you can massage everything to fit.

I'm just going through the info I remember that's over at ephatch...
The JDM and European CTRs are differently spec'd. Honda, as usual, kept the best for their home market.
For the header, you don't need the Type-R header; pretty much any K-series header will bolt onto the motor, and fitment concerns are limited to the swaybar and the rest of the exhaust system. I've got a Type-S header & cat on my stock A3, for example, which bolts onto the JDM CTR-spec Fujitsubo catback with no adapter or cutting.
For a front sway to clear the 4-2-1 ITR header, you could use the aforementioned ITR front sway, but you'd need ITR lower control arms because the endpoints are different. You could also use the Toda front sway and fit it onto the stock LCAs, or you could use an '01-era Civic front sway (thinner for better corner exit traction, and with a bigger center hump).

Go to ephatch.com It has all the info you need about this swap. And FYI, the K20z1 is a damned hard swap because of the drive by wire throttle system.
An A2 swap is easy peazy. Just be sure to have K-Pro ready to go.

FYI there is no drive by wire system on the RSX, i think your thinking of the 06 FG SI civic which has a k20z3
the k20z1 and k20a2 found in the RSX-s has a standard throttle cable
so a Z1 would be just as easy as that A2

The K20A(*) [DC5 ITR and EP3 CTR] motor and the USDM K20A2 motor are both pretty easy, drop in solutions.
You can use the stock USDM EP3 Si five speed with them too, if you want, and the USDM EP3 Si has a better axle ratio than the transmission that'll come with the K20A2 swap.
Hondata K Pro is perfect, and you should probably count on using that computer. However, if you get the K20A(*) or K20A2 ECU, they will also work. You will not get as much power out of them as you would with the K Pro.
Remember that it's not a given that you are getting a Torsen axle with your swap. It was never offered on any USDM K20A2, and it depends on the market whether or not it was available for the K20A(*) motor that you'll be buying.
You're not going to be satisfied with just the motor swap. I can bet you that you'll be keeping your eyes open for a five bolt suspension and brakes swap from a USDM Type S.
A 200 HP EP3 is a nice car to own. Don't get too carried away with spending the money, and you'll end up with a right speedy little thing that'll still get you 30 mpg most of the time.

Re: Civic Si w/ RSX Type-R swap (LambertdelSol)
i bought a complete swap (k20a2) for $3625 from emmanuels used cars in houston, texas. i got the harness, ecu motor and tranny, stock mounts fit, i just but energy suspension motor mount bushings in, and for the shifter i used the buddy club short shifter, it has 6spd and reverse so u dont have to cut or grind n e thing, the swap went smooth, but if u want to run the stock type S ecu, you have to take it back to an acura dealership and have them program ur keys to work with ur ecu or ur ecu to work with ur key.
