i hav a 93 impreza l. it has a poopy ej18 and its a dam dog. i want to do performance to my suby to keep up wit my friends 91 nissan sunny super saloon. should d a ej25 swap or a ej22 swap??? i know a lot about gc8s and i hav no idea on how to do performance on a ej18. any help or advice would b much appreciated.. thanx

 

I have an EJ22, and I can tell you that even if I swapped from A/T to an M/T, it is not going to change the fact that it's only got 133bhp. With that in mind, if you are not going to spend the money to do an EJ205, EJ255, EJ257, or an EJ207, then I would personally go with an EJ25 swap from an RS. It will be far more worth your time/money invested as opposed to an EJ22 swap. That's my opinion at least.

 

alrite my pap owns a junk yard. i think he has a good running ej25 sittin around so ill check it out. now im not sure but will my ej18 5 speed tranny work on it or would i hav to get a 5 speed ej25 tranny?? thanx

 

You would be running the EJ25 ecu, so you should go with the RS 5spd, which is like a 3.90, or was it a 4.11? I can't remember. Either way, I think it's different from the earlier 93-96 5spd's, so you'd just want to look for the entire motor, ECU, and drivetrain from a 98-01 RS
