JDM Engine Swaps for EK9 – What’s Actually Worth It in 2026?

[Blueysengineshop]

Hey EK9 crew,

Been diving deep into JDM engine options lately and wanted to get the hive mind on what’s actually worth doing in 2026.

I’m seeing a lot of:

• B16B / B18C Type R engines
• K20A / K24A imports
• Even some wilder stuff like H22 or F20C transplants

Questions for you guys:

1. What JDM engine swap have you done (or are planning) on your EK9 and how has it been on the street/track?
2. Reliability vs power – are the legendary JDM motors still holding up or are they getting tired?
3. Budget-friendly vs dream builds – what would you do with ~$3-5k vs $8k+?
4. Any horror stories or absolute wins with wiring, mounts, ECU, etc.

Drop your build pics, dyno sheets, or opinions below. Especially interested in real-world experiences from people who’ve been running them for years.

Let’s make this the ultimate JDM EK9 engine thread!
