Hello there New to the Club..Have a few questions though..I have an 03 WRX with a blown engine..Now should i replace the Engine with a Ej205? or should i go with the JDM engine and have an Ej207? I understand that i will need to install the AVCS wiring as well as a JDM wiring harness and ECU. However my quetion is. Is it worth it? and can it be done quicky? I will have 10 days to make the swap.. Where could i but either a JDM or USDM Long block? Is it worth it to swap and make a JDM engine? and if so..which version V7. V8. or V9?
