The 'tested' 1996 EJ22E that I got for my '99 SUS turned out to have a seeping head gasket. Not much coolant was getting into the chamber, but it was enough to clean the spark plug and get me to pull the cylinder heads.. Now I'm at a crossroads. I'm considering an EJ22D conversion using the 25D heads and intake from the car. I know it works and I would be able to keep my original Y pipe but I don't know the 'cost' to having the heads done. The 2.2L heads are good. I'v checked them for cracks. If they need cut, I could do the old sand paper on a pane of glass trick for free, or it would be $40 at Napa but the machinist there goes on his own schedule nowadays, so who knows when I could get them back..
Are there any gotcha's with the 25D heads? The 2.5L runs like a pile of crap because it is ingesting so much coolant into 1 cylinder that it has a consistent miss once it's warm. Oil is clean, and the coolant was actually pretty clean also, so it has to be all going thru the cylinders, so I'm afraid of bent valves.. How much power does the EJ22D swap aid over a normal EJ22E? Most of my driving is country back roads if that makes a difference. Low end is where I'd like any gains to be. I know the 22E swap drops 30hp from the 25D motor
