vanman281 Posted May 19, 2010 Share Posted May 19, 2010 I didn't search, but I found a ej25 DOHC whcih i would like to swap in with ym ej22 SOHC, Is there any way my ecu will be plug and play? I am looking at the motor tomorrow the 20th. If it is a plug and play deal i will get it, because i currently have bad rings on ym 22 just put 2 k into everything but the shortlbokc and it's still missfiring in the third cylinder. Rather than me putting new rings ona motor i've beat on i would rather buy this 25 with updated HG's, timing belt, new water and oil pump and be on my way with a 2.5. Please let me know if they will merge, or if i will have problems because of the head difference. Link to comment Share on other sites More sharing options...
