    Just recently got an EP3 and my uncle had previously installed his weapon R intake but there is a hose that is not connected to anything or plugged up, is it a concern? Im pretty sure they have been driving like this for however much of the 170,XXX miles.

    So just got this EP3 and the a3 is still running well enough minus some vtec solenoid issues ive been fighting with. But I know this engine isnt going to ever be what im wanting it to be without spending a ton on it and with 215k im sure its not worth the upgrades/cost to do them. I really...

    Hey guys I just got an EP3 Si trans with 140k miles. I’m planning on putting a k20z3 LSD in it. I was wondering if while I’m in there I should just bite the bullet and install some new diff carrier bearings.

    I'm typing this out to document all of the things that I've had to do to my 05 EP3 to make a 06 RSX Type S powertrain completely compatible with my EP3, including making it PA safety and emission compliant (which is very difficult to do in my county). I'm also a tech working at a Honda...
  13. 2001+ Civic EP3 / RSX DC5 / EM2
    So, I swapped a 06 RSX Type S K20z1 and trans into my daily EP3. I used jumper harnesses to make the speed sensor and the ecu from the RSX plug into the car, and I'm using my stock EP3 engine wiring harness to run my car. Before I wired the K-Tuned VSS Converter into place, the harnesses did...

    Hey all, new here. I'm not a big Honda guy, but my dad always was so sorry if i sound un-educated because i am lol. In September 2014, my dad passed away in a tragic motorcycle accident and all that I've had left of him is his old EP3 he bought brand new in 2003. As we all know the K20a3 is junk...
