2002 Civic Si kept the 4x100 bolt pattern. in 2003, they changed to a 5x114.3. That said, try and find a knuckle assembly from a 2002 Si
RSX e-brake cables will work, but it's a tight fit. You'll have to open up the supporting brackets to take up basically any slack in the line to get it to reach. EP3 (02-05 Si) e-brake cables are too short for the coupe/sedan.
Yeah ive seen quite a few vids on this and it isnt too difficult. My only problem is that im in the U.S. and live in the PA/NJ area. Even though there are junkyards in every direction people around here mod hondas day and night. Going to these junkyards are not gonna yield good finds so its kind of a last resort. Lol and with how they are with hondas here chances of me finding an RSX or even an Si in the junk bin is very slim. Oh and thanks for the tip about the VSS from the drum working with the disc knuckles! In all the vids i watched and research about the disc swap i never came across that info.
-Slotted front rotors $200
-high end street pads $100
-braided lines on all four corners $150
-dot4 high temp fluid
Sounds good to me. First thing i actually want to do is that rear disc brake conversion. I dont know how to replace drum brakes nor do i want to seeing as how its considered to be obsolete. Besides what point is there in adding any extra hp if your brakes cant handle it...
Hey guys just went to a junkyard and im getting the A2 head off of an ES2. Can you guys tell me exactly everything i have to get pulled off of this so that it runs properly with my motor? I can upload pics if needed.
Make sure you grab the ECU, the wiring harness, and obviously the head.
when you take the head off, loosen the head bolts in opposite direction of torquing them. Apparently, you risk the chance of warping the head if you don't...

Thanks. I havent gone to pick up the stuff yet cuz i was just having them remove it for me because i was getting a lot of other stuff with it and dont have the tools for everything. They were closing at the time and shooing me out the door. Im supposed to be going to go pick up everything but i have a feeling its going to be a problem. I told them i needed the vtec head and everything required for it to run. When i told them i needed the the entire head and the solenoid and the egr and ecu etc; they looked at me like i had 6 heads. On the receipt it says COMPLETE ENGINE HEAD. So if all the parts arent there ill tell them what i need and if its an issue ill just get a refund.
My goal for now is to at least get the vtec up and running. Next would be to get a proper ecu for tuning and the kpro. That might take a while due to the price of the kpro but in between those i plan on doing the rear disc conversion. In my junkyard search i actually found one that had the disc trailing arms but they were actually in the process of being ripped off by 2 dudes so i was SOL cuz that was the only one i found from the yards i went to.
-head
-header (best to buy a new performance header, no point buying an old ugly rusty header)
-O2 sensor wires need to be altered to reach the new locations.
-vtec ecu
-engine harness, or you can try to pin in a wired connection from the ecu yto vtec solinoid
-reflash the vtec ecu/key at honda to work with your original key/ignition
(You will be able to drive the car with the original ecu, down to honda. Then remove the glove box and unbolt the ecu but leave it wired up, to save money and time. They'll recode everything and you're good to go)
The junkyard visit didnt go so well. I showed up and asked for my stuff and when i saw the valve cover with no other parts i knew it was gonna be a bad day. They didnt even have the head, just the vavlve cover and some poorly taken apart interior panels i wanted. When i asked about the car they had already crushed it! I argued with them for about 30 mins until they issued a FULL refund.
I visited a few other junkyards but didnt find much. I might be stuck having to order parts from online which i didnt want tondo because they will be vastly more expensive.
You can, but then you will have 5 bolt in the rear, and I don't know if the 5 bolt hubs for the front will work with the d17 axles
Im really just worried about fit. Ive been looking around on forums and getting mixed answers about this swap. Have you actually done this particular swap before with 02 rsx to 01 civic spindles? Btw if i can do this ill just do a hub swap back to 4 prong for the rears.
This thread has lots of info, unfortunately the pics are gone
Im not so sure im fully understanding what im reading in that thread... Do i only need the front spindle parts swapped if im doing a k motor swap or do they mean i have to swap all 4 in general? I know that if i get the rears it saying i have to upgrade the wheels to 16" but why cant i keep the fronts as is?
You can use the RSX rear knuckle/hubs if you want disc brakes, but you will also be going to 5 lug. I've never heard of anyone saying you need larger wheels to do so. The Civic Si has the same size rear disc brakes and comes with 15" wheels. If you want rear disc brakes and 4 lug you have to find a '02-'03 Civic Si (USDM).
As for the fronts the RSX Type S has larger brake rotors which may require a larger wheel. However, these hubs will not accept the Civic's axles. Base model RSX would be a direct swap and give you 5 lug hubs.

Its expensive I know but it will cut out the cost of having to do the 4 prong hub conversion from pulling the rsx spindles not to mention not being able to get them off due to them being seized and rusted. Only problem im running into now is trying to figure out how to order a brake set. I gotta get calipers rotors and pads and also heard i should upgrade the master cylinder. How do i find out what size calipers these things use?
Yes, i did actually. The problem is that on that thread all the info is in regards to parts swapped from other cars. This particular piece from my last post was made specifically for the 01 civic so i am in uncharted territory with this. I will make a few calls. One to Carid and one to mevotech(if possible) if i dont get results from carid. If i dont get much info from them then it'll be trial and error from there. I really dont want to waste time doing that but if it comes down to it ill post results for future references...
On the hondata website regarding the kpro there is some info i found that states there is a base map built in for a non vtec d17 turbo. Does that mean i can turbo the D17A1 and use the kpro to reflash and tune from there?
If you are looking for a rear disc conversion I have all the parts you need for the 4 lug version off an EP3. They are currently at another house right now and I was planning on getting pictures to sell them this weekend. When I get all that I will PM you everything or you can PM me your phone number and I can text you the info.
Im pretty sure I have a DIY with pics saved somewhere on one of my computers for this conversion as well.
This is from a different forum but a good thread to read through for boosting the D17. Speedfoos and Andyman were the resident experts on boosting the D17 back in the day. Ask Foos your turbo questions here
Here is another thread from Andyman talking about the different Turbo Kits that used to be available. His second post lists prices for his own build and he talks a little about his build as well. d17 Available Turbo Kits
If you decide to turbo, there have been some reporting of 35+ HP gains from porting and polishing the head. So a small turbo kit plus PnP'd head should get you close to 200 HP I would think.

Yeah, you shouldn't have an issue running the kpro for the D17A1.
You have the option of setting when the vtec kicks in...just set the RPMS way past your revlimiter so it won't kick in.

Thanks for this! I must say that the hondata website needs to be updated. There is information on it that is contradictory and downright wrong. It is very confusing to someone who is just getting into this. For instance, it first tells you that a stock D17 cant be programmed and in the same section a few bullet points later it say it includes base maps for a D17 non vtec AND a D17 non vtec TURBO. If you turbo the non vtec D17 and load the base map then have a tuner configure it from there isnt that the same as programming it to do what you want?! And if they did that why not just add a base map for D17 vtec and D17 vtec turbo?! Also the thing i found was wrong is when it came down to the donor ecu's it says that a crv 5speed ecu can be used and lists its PPA-A0 status for any 5speed crv made from 02-04. I found one in a junkyard yesterday PPA-A04 and found out it cant be used even though the site says it can.... Glad i only paid $19 for it.
FYI the D17 ECU can NOT be programmed.
The base maps are loaded onto the programmable ecu.
Oh ok. Thanks for clearing that up. So i still need to get a proper donor ecu. I just dont understand why they list the PPA-A0 as a proper donor ecu and then it doesnt work. I got pretty lucky with finding that one. It seems the ONLY one that will work are from an rsx manual and thats like looking for a needle in a haystack.
I'm currently running an Element ECU with a special conversion wiring harness utilizing Ktuner software.
I think i'm the only one currently doing this in the world....
For Hondata i do believe the rsx is just about the only way to go.
You may be able to try an Element ECU with Hondata, but you will need a special harness.
