Bambammcd Posted September 30, 2013 Share Posted September 30, 2013 (edited) Ok I'm try to put a shoping list togther for my franken motor build. I'm planning on putting it in my 1991 Subaru loyale. here is what i have been able to figure out so far. ej25d ej22e heads delta 220 torque cams. cometic head gasket. Im wondering what else ill need for the motor build, and also if all ej22e heads are single port or dual port. what ecu should i run? thanks for the help Edited September 30, 2013 by Bambammcd Link to comment Share on other sites More sharing options...
MilesFox Posted September 30, 2013 Share Posted September 30, 2013 Use a complete ej22e as your donor, and throw the 2.5 block in between. preferrable a 95or 96 legacy with obd2 and dual port exhaust. Or use the engine from a 90-94 legacy, and use an obd2 intake and harness from any 95-99 legacy Link to comment Share on other sites More sharing options...
Bambammcd Posted September 30, 2013 Author Share Posted September 30, 2013 Cool! So if i use the 2.2 from the 95-96 engine will that be sohc or dohc? Also which set up is preferred? Link to comment Share on other sites More sharing options...
MilesFox Posted September 30, 2013 Share Posted September 30, 2013 The 95/96 should be mostly dual ports. 95 for sure, some 96 and 97 are single ports. The dual port head is preferrable. The roller rocker cams in the single port heads are disireable. Putting the roller rocker cams in the dual port heads is the way to go for a torque cam. The obd2 harness would be the desired one (95-99) since you can use a code scanner with it. The obd2 intake meets all 2.2 phase 1 engines 90-98 legacy and thru 99 impreza.

Bambammcd Posted October 1, 2013 Author Share Posted October 1, 2013 So probably the best route would be to find a wrecked 95-97 legacy with the dual port head and buying the hole thing so i have the harness, the engine and the ecu. then buying the 2.5 block and the roller rocker cams. where the Imprezas' dual port as well?

MilesFox Posted October 1, 2013 Share Posted October 1, 2013 YOu will find dual pirts thru 96, the impreza is single port after 96/97 but kep tht eej22 thru 99 or maybe even 01. the legacy ent to 2.5 by 98 and 99. you will find 2.2's for later years with impreza.

franklinstower Posted October 7, 2013 Share Posted October 7, 2013 i disagree on the roller rocker cams. I was at Delta last week with both the roller rocker cams and flat tappet cams. Ken said I was limited to a 200 grind on the roller rocker cam, but I could get the 220 grind on the flat tappet cam. The roller rocker cams are hardened and have a different profile, according to Delta. They have to grind them much slower and cost an extra $40 for the pair to grind. But regardless of the cost, he said using the flat tappet cam gives you a better profile. For your 2.5 block, I would stay away from the '96 block unless you want even higher compression. The '96 2.5 had a different piston shape with higher compression and was the only ph1 2.5 that required premium. Link to comment Share on other sites More sharing options...
86BRATMAN Posted October 7, 2013 Share Posted October 7, 2013 Every 96 ej22 I've ever seen has been single port. And you don't want 99-01 ej22 heads, they are phase 2, larger chambered and will lower your compression when used on the ej25d(unless its a 96) 1 Link to comment Share on other sites More sharing options...
Bambammcd Posted October 8, 2013 Author Share Posted October 8, 2013 how high of a compression would we be talking about with the 96 2.5? Premium around here is only at 91 octane. Link to comment Share on other sites More sharing options...
suprunner Posted May 24, 2014 Share Posted May 24, 2014 What problems would I run into using heads/exhaust/intake/ECU from a 1993 Legacy? Will timing be wrong? Link to comment Share on other sites More sharing options...
