***** DISCLAIMER *****
The following is an analysis of the USDM OEM Part List for the 99-00 CIVIC 2DR EX (MT, non-ABS)
, and the 99-00 CIVIC 2DR SI
. The differences discussed herein are BASED ENTIRELY ON THE USDM OEM PART NUMBER DISPLAYED AT AN ONLINE RETAILER
, so any noted differences do not necessarily mean that one absolutely needs to swap or use something (i.e. Prop Valve, Nuts, Brackets etc.). Use your best judgement when drawing your own conclusions, and understand that I take no responsibility for any damages or injury to property or person as a result of one using this information. This is not a How-To. It is merely a comparison between the two models' parts list, with comments. So, to the best of my knowledge...
The differences between the Brake Systems of the *USDM* 99-00 CIVIC 2DR EX (MT, non-ABS) and 99-00 CIVIC 2DR SI are as follows
EXACT SAME SETUP. You don't believe me??? Then double-browse and toggle, bitch!!
The Rear Brake Hose for the EX is actually split into 2 smaller hoses. The SI uses a single hose from the Hard Line outlet, and uses 2 extra bolts to mount the Rear Brake Hose. The end fittings of the hoses are different as well, as the Disc Brake Hoses attach to the Banjo Bolt on the Caliper, while Drum Brake Hoses attach to the Drum's Hydraulic Cylinder.
: 46331-S04-000, 46361-S04-000 (R/L Hose - To Drum); 2 x (01466-S04-000) (Hose - To Hard Line)
: 01466-S04-900, 01468-S04-900, (R/L Hoses); 2 x (93403-08020-08) (Bolts)
The Proportioning Valve IS DIFFERENT. **Whether or not a swap is "needed" is debatable.**
Read more about it in the links below...
Nuts... For some reason, the EX uses a "Special Nut (6x18)", and the SI uses a "Paint Cutting Nut (6mm)". It's #22 in the upper left corner of the following diagram.
Chassis/Master Power (Hydraulics)
The entire Brake Booster & Brake Master Cylinder system is identical except for the "Master Power Tube Assembly". I don't know for sure what accounts for this, but it is not considered a "need for swap" item. The only thing I can think of that accounts for this difference is in the spacing of the Engine Bay. Maybe the B-series requires a slightly different route for its Brake Hydraulics. I don't know, since I've never had either in my hands, but anyway...
Chassis/Parking Brake (E-Brake)
The difference here is in the end fittings for the cables, and the associated hardware. Some people have claimed you can use Integra cables, DelSol cables, blah blah blah. Go away. Re-read the Topic Title...
The good thing is, we know SI cables will FIT PERFECTLY!!!
(Cables); 2 x (43471-SD2-930
) (Clevis Pin); 2 x (90705-SD2-931
) (Cotter Pin); 2 x (90651-SV1-A01
) (Cable-to-Caliper Retaining Clip)
Chassis/Rear Lower Arm
There are actually a lot of PN differences between the "Rear Lower Arm" assemblies, but a lot of them are the result of the SI actually HAVING an Anti-Sway Bar (Spring). For this Topic's purpose, the "real" differences are in the Brake Hose Brackets and the *** SPINDLE *** (Trailing Arm). Some people don't switch the Brake Hose Bracket, or choose not to use it. The Spindle is what makes the OEM 99-00 EX to SI Disc Conversion possible
. In fact, you don't need to swap the Trailing Arm out. You can swap from the Spindle outward... The only way around it is to fabricate a bracket onto which you'll mount your Calipers. AEM used to make a conversion kit, but they don't anymore. In fact, they're not even in the Brake business... Anyway...

Chassis/Rear Brake (Drum/Disc)
The part differences here are too numerous to list, as some of the "Assemblies" are listed as individual parts. The best thing I can do is provide links to their respective systems. It would help more to list the parts they have IN COMMON
EX & SI Use
: 2 x (42324-SB2-020) (Hub Washer); 2 x (42326-SB2-000) (Hub Cap); 2 x (42326-SB2-000) (Bleeder Screw Cap); 8 x (90113-SA0-006 or 90113-SA0-025) (Lug Studs); 2 x (90305-692-010) (Spindle Nut (with raised shoulder))

(<FONT COLOR="red">EDIT: Correction...!!!</FONT>)
The Disc Brake Hub/Bearing Assembly differs from its Drum Brake counterpart (see 2 posts down).
There are also some bolts that are commonly used, but in different ways...
Other than that, ** THERE ARE NO OTHER DIFFERENCES IN THE BRAKE SYSTEMS BETWEEN THE 99-00 CIVIC 2DR EX (MT, non-ABS) AND THE 99-00 CIVIC 2DR SI **
. I suppose you might also use this information to do a Disc to Drum Swap if you wanted to take your car back to stock...

Don't ask me.. EDUCATE TYSELF, MY BROTHER!!! ETYMOLOGICAL ROOTS, BABY!
I want to thank HondaPartsDeals.com
, BREMBO Brakes For their downloadable OEM Replacement catalog (if I can find a link, I'll update..), and the many contributors to and moderators of this great site. I hope I have been able to help guide those who were wondering the same things I was when I started out. Last but not least, I want to thank **YOU** for taking the time to fully and carefully read what was written. I only hope it was worth it... ahem...
, take this time to contemplate the Title of this Topic, and understand how much it would help others who might need this information to not have to wade through: posts unrelated to the Models and Systems mentioned above; trivial interjections; tangential escapades; "My Cyber-Dick is bigger than Your Cyber-Dick" arguments; and the mindless dribble of the Original Poster relating to the frustrations of the above... I welcome corrections provided they are detailed and provable (pix!! linx!!), and while the comparison is complete (...?), there are some differences I can't explain. Feel free to contribute in that regard.
Hope this helps...
