    Hi, I have a JDM-spec K20A swapped in a Lotus Elise Mk1 in 2009 here in Germany by Komo-Tec. The engine is stock with changes that come with the swap. It has different headers for the application, a cat and a Janspeed exhaust. I used the OEM ECU for a long time and then had – in hindsight -...
  2. General K-series related talk
    I am planning to swap the engine in my Honda Accord VII CL7 to the K20A FD2. In the plans I have a short intake, throttle with cruise control from DC5 67mm, suction shaft K24Z3, exhaust shaft K24A3/K20A FD2. I plan to use the AST5 box. Is this gearbox really gonna kill my performance? This car...

    So I have an 03 Honda Accord Ex coupe, five speed, 2.4i. The K 24 A1 that’s in my car now. The question is can I use that computer with a K 24 JDM a2 rrb with the computer I have or do I need the TSX computer? What computer do I need to run that JDM motor? All answers will help.
  4. General K-series related talk
    Hey guys. I k24a1 swapped my auto ek. I purchased a manual PPA ecu with key and immobilizer . Also purchased a k tuned immobilizer bypass and installed it using KTuned’s instructions since I couldn’t find a wiring diagram for the PPA ecu. I spliced the auto trans cable to show its in park. For...
  5. 8th generation Civics 2006+
    Hello all, I am doing a swap on the above car as the valves are all bent and no compression at all. I know the exhaust header is different and the oil dip stick but other than that what else should I be concerned with when putting this engine in. I have done an R18 to R18 but never a JDM K20a...
  6. All Motor K series Technical Discussion
    Hey y'all! I am new to the K series entirely. This swap will be my first swap that uses an engine from a different manufacturer than the chassis and I really need help understanding wiring.

  8. Wiring and Electronics
    Not 100% sure if this belongs here so please move if another spot fits better. So I'm planning on doing a K24 swap into an older classic car (not a Honda). After planning a good bit out I came to realize that I don't know how I'm going to know my speed, revs, engine temp, fuel, etc since I...
  9. All other models (mr2, mini etc)
    Got my JDM K24A engine a while back that is supposed to be out of a 2006 crv or element, and I got a harness from jackspania racing. Now that I’m trying to work on my swap into an 88 s15 (gmc) I’m realizing that none of the sensors on the engine or plugs on the harness match up. The engine came...

  11. 2001+ Civic EP3 / RSX DC5 / EM2
    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...
  12. 1988-1991 EF Civic / CRX K-Series Swap
    New to K-Series, Swaps, and Turbocharging. Been learning and have come up with a rough build, advice? Planning to K-swap an 89' CRX Si, the purpose is daily driving/weekend autocross. Power Goal is 300WHP to at very most 500HP. I plan on using an all-stock K20a2 with the RSX-base 5-speed...
  13. 2001+ Civic EP3 / RSX DC5 / EM2
    I have an 03 RSX Type S and I plan on swapping a K20A into it to but i'm concerned with whether I absolutely need to get the motor from the DC5-R or if I could put the CL7-R motor in. Only reason i'd rather get the CL7 K20A motor is because it is siginificantly cheaper than the DC5's K20A. What...

    Hello I am relatively new to hondas , I purchased a k24z7 transmission thinking it was a k20z3 trans only to be lied to. I plan on putting this trans on my k20a2. Will they bolt up? And will I have to change anything about the trans to fit my Rsx? Such as the shift selector or the speed sensor...

  16. Wiring and Electronics
    So I've got a question... I have a 1961 MG Midget Can be seen here and I just recently purchased an 03 Accord (auto) for a good price solely for the motor.

    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...
