cmmc Posted December 3, 2013 Share Posted December 3, 2013 Hi guys, I am new to subarus but not to cars and have some q's that i was hoping you could help me with? I am working on a 1998 Forrester with a 2.5 and bad motor, and a 92 legacy with a 2.2 and am in the process of swapping in the 2.2 into the 2.5. i am assuming that i will need the ecu and harness form the obd I and put it into the odb II car is this a doable thing or am i asking for trouble?

idosubaru Posted December 3, 2013 Share Posted December 3, 2013 of course if you do a complete wiring swap it's doable but that's tons of work. there are a couple of easier options: 1. find a OBDII EJ22 intake manifold (95-98 EJ22), bolt it on top of the 92 EJ22 and it's plug and play into the 98 with zero wiring work. that is what i would do, and have done before. 2. you could attempt to transfer the EJ25 engine side wiring harness onto the 92 intake manifold - i *think* it's possible. the west coast folks should know as your early EJ's haven't all rusted to oblivion like ours years ago.

cmmc Posted December 3, 2013 Author Share Posted December 3, 2013 Thank you, I will go look and the manifolds Link to comment Share on other sites More sharing options...
86BRATMAN Posted December 3, 2013 Share Posted December 3, 2013 You will need to use your ej25 throttle body at the very least. Best bet would be to swap over everything between the two manifolds. The simplest way to do this conversion would be to find a 95-98 ej22 complete intake manifold, with egr because your ej25 has it and the 92 ej22 does not. There is a thread in the USRM section outlining how to work around that problem, check it out http://www.ultimatesubaru.org/forum/topic/137829-using-a-non-egr-engine-in-subaru-with-egr-exhaust-gas-recirculation-valve/?do=findComment&comment=1160910 Link to comment Share on other sites More sharing options...
cmmc Posted December 4, 2013 Author Share Posted December 4, 2013 (edited) k i have been looking at the manifolds and they look like they will swap but i am finding a cam sensor that goes on the block that will not swap any thoughts Sorry feel very dumb was just looking at the harness plugs on the back removerd and found them to be identical so just swapped them over am now starting on the maniforld swap will keep you aprised thanks for you help so far Edited December 4, 2013 by cmmc Link to comment Share on other sites More sharing options...
cmmc Posted December 4, 2013 Author Share Posted December 4, 2013 ok guys I have just completed swapping everthing over between the two IM including the the throttle body and all the sensors on the block as well just need the specs to tighten down the IM again could anyone out there help me with the numbers and also the seqence. thank you once more for your help it has been invaluable Link to comment Share on other sites More sharing options...
ocei77 Posted December 4, 2013 Share Posted December 4, 2013 18.1 +/- 1.4 ft lbs. Just do the inner ones first, after snugging them all down. O. Link to comment Share on other sites More sharing options...

86BRATMAN Posted December 4, 2013 Share Posted December 4, 2013 If you're talking about using the ej25 manifold on the ej22 it won't work. The only manifolds that you can use are 95-98 ej22 equiped with egr. Link to comment Share on other sites More sharing options...

The only manifolds that you can use are 95-98 ej22 equiped with egr. he's not. he installed the EJ25 intake manifold wiring harness onto the EJ22 intake manifold so he's retaining the manifold with the engine.

cmmc Posted December 5, 2013 Author Share Posted December 5, 2013 k was putting on the new clutch this morning and torquing them dowm and bang the first one snapped i am used to american v8s and thought that the cutch would be around 65lbs that is not the case i got the bolt out of the flywheel quite easily but am now searching for the right spec.

Gloyale Posted December 5, 2013 Share Posted December 5, 2013 23~28 ft./lbs. is what I shoot for. Snug and even is more important than drasticly tight. remember, they are just M8 bolts. Subaru Head bolts don't even see 65 ft./lbs back off a bit muscle man lol Link to comment Share on other sites More sharing options...
cmmc Posted December 6, 2013 Author Share Posted December 6, 2013 wee haa the engine fired right up on the first try and purred like a kitten. took it for a drive yesterday down to napa and almost got stuck right off the bat(stupid winter storms). lol it ran very well with no drivablity problems that i can tell other that the check engine light is on (no egr so is going to stay on). To any one else doing this swap you will also need the alt and the ac compresser off the newer 2.5 motor as the r134a compressor will not fit in the r12 compressor bracket. just need to adjust the coolant and install the block heater cord (it was -25F here this morning) I want to thank you all for your help.

ocei77 Posted December 6, 2013 Share Posted December 6, 2013 Glad it all worked out. If you need the CEL off for inspection, do a search. There is an egr workaround using a t from the intake manifold. O. Link to comment Share on other sites More sharing options...
