Well, that is unfortunate.
So now I need to source a number of different parts to make this EJ25 long block work in my application. Obviously the simplest solution would be to source all parts off another EJ253 and use that harness/ecu as well. Unfortunately, this leaves me with two vehicles in 1999 to work from as the 05+ vehicles have the I-Active valve system which my long block does not have.
First question: Is there another variant of EJ25 (251 or 252) whose components will mechanically work with this long block? If I am going to have to transplant a different harness and ECU into the vehicle, I don't have any problem switching to MAP instead of MAF.
Second question: Will the exhaust manifolds from the EJ22 fit this block? I have a custom header for this application that I need to use.
