  2. The DIY Garage RSX
    Hi! Last week I bought an RSX cause' my last car blew up. I was looking at tuning options but I see everyone saying that the multiplex unit is a bitch to work with unless your using hondata or something. Would anyone be able to clairify what the unit actually does specifically if it needs to be...

    Hi All, I'm currently in the process of doing a k24a2 swap into my base 03 RSX. The engine is from an 04-05 TSX. I fully realize and anticipate some will tell me to search the forums, and I get that, I really do. However, I have searched extensively, through this community and many others, and...

  6. Bolt-On Basics: RSX (Base)
    I was wondering if anyone knows if a k24a2 head will go onto a k20a3 block without any issues? Some people say something about valve to piston clearance but that doesn't make sense to me. I know the k20a2 head will work and they are almost the same but k24a2 head is about half the price in my area.

  8. Problems & Solutions RSX
    While handling the timing chain tensioner the pin I was using fell out and the sprocket fully extended. How do you reset or compress the tensioner? On YouTube, I have seen people reset tensioners for other cars using a screw driver.

    Is this swap possible? My gf totaled my 05 but my engine and trans are solid with very low miles and I found an 03 shell but I’m not sure if everything will line up? I have all OEM parts on 05 needed for the swap. Any help will be appreciated thanks!
  10. Problems & Solutions RSX
    Hey guys. I am in the process of replacing my RSX engine with another k20a3. When I removed it, I went out the top after dropping the tranny out the bottom, like spaz did in his videos. I used a long tow strap that I was able to wrap around the engine 3 times to lift it out, and when it was at...
  11. The DIY Garage RSX
    Hi, I have purchased a K20A3 (and clutch kit) to replace the K20A3 (and old clutch) currently in my base 06 RSX that has a cracked block. All of the sudden, the mechanic that was going to do it is too busy to do the swap anytime soon. The next best quote I got was $700 CAD more. So I started...
  12. Problems & Solutions RSX
    I reinstalled the cylinder head on the block on my K20A3 engine and would like to run a leak test before proceeding further. What are the connection points and the specs as far as air pressure bleed? Thanks.
  13. Turbo RSX
    Hey I have a quick question, Building a turbo K20a3 obviously. Would I be better off balancing the beefy ass rods, pistons, and wrist pins to my stock a3 crankshaft ( since I know it's not balanced from the factory ) or just getting a good used a2 crank and rods, pistons, and pins instead? I...
  14. Turbo RSX
    Hey I just have a simple question, I am getting a parts list together for a 2004 base RSX K20a3 engine turbo build. I already know I'm going to go with a set of 10 to 1 pistons ( haven't decided which brand yet ). My question lies with the decision of what millimeter size to go with? And yes...
  15. Problems & Solutions RSX
    Hey all, Does anyone know if there are any differences between the K20A3 power steering pump and the K20A2 power steering pump? The Honda part numbers are slightly different, but it seems aftermarket power steering part numbers don't differ between the two engines. I have searched on Google...

    Quck question. If you switch out the roller rocker assembly and the valvetrain is there any difference between an A3 head and an A2 head?
  18. Bolt-On Basics: RSX (Base)
    Im looking for a fuel rail for the K20a3 base model and i don't see many options for stylized aftermarket fuel rails for this engine. Are all k20's the same for fuel rails or is the A3 needing a specific setup?

  20. Transmission & Drive Train RSX
    Debating on possibly adding a LSD to my K20a3 transmission, currently a little over 100k mainly because the transmission is out as I'm doing the clutch/flywheel and I'm not entirely sure it's worth it for just daily driving but I'm researching just to cover my bases. I run 225/45/17 Toyo...
