Ok so I am semi interested in doing an ej20 swap sometime in the future. And i have to ask, doyou need to swap the transmission out along with the motor, or does the ej25 transmission work with the ej20 motor????

Thanks

 

check out the march issue of sport compact car. There is a very good article on the ej20 swap.

 

the ej25 transmission works w/ej20 motor. i-speed even recommends the shorter ratio gearing of the rs tranny.
