i have a 05 4eat and i have been looking at full jdm ej20t v6 complete engine w/ transmissions. it comes with complete motor, 5 speed tranny, ecu, starter, sensors, etc. i have found one for about $5000 without shipping. would this swap be worth it? will i need any other parts to complete this swap? will a cobb accessport work with the jdm ecu?
