shoebee2 Posted May 15, 2015 Share Posted May 15, 2015 I picked up a really nice 98-99 lob limited last week for the cost of moving it outa the guys yard. I was told it had rod knock and sure enough it went bang bang. Pulled the engine, short version is the block is junk, heads are marginal. Looks like done material for future projects. Bought a JDM 2.5 for my year and model from JDM-Alliance for 950. Less than cost of rebuilding a core. Compression is good at 142 across the board, plugs are clean. Pulled front covers and timing belt looks new, idlers are all bright and sparkly. the engine is SUPPOSED to have less than 40k on it and by looking at it I would agree its possible. Upgraded head gaskets and upgraded rear oil cover installed. Im going to run it. The swap engine is not egr equiped so I "should" swap out the intake, drill and tap right head yada yada yada. Questions: Do I have to swap out the intake at all? Will it work without an erg system? The exhaust was left on. The down pipes wrap around the front of the block tucking under the front with an exit pipe to the rear on left. Way different than my lob which drop and go directly to the "Y" pipe. Clearly I won't use that exhaust but does it indicate anything I should be aware of? Any gotchas I should look out for? Cover me Hoss, Im goin in.

bratman18 Posted May 15, 2015 Share Posted May 15, 2015 Either the exhaust is aftermarket, or its a turbo motor. Link to comment Share on other sites More sharing options...
shoebee2 Posted May 15, 2015 Author Share Posted May 15, 2015 its not aftermarket, at least I don't think it is. Got Subaru stamped all over it. Maybe the exhaust is from a turbo engine, no idea myself, but the engine has no turbo or plumbing for a turbo. Link to comment Share on other sites More sharing options...
shoebee2 Posted May 16, 2015 Author Share Posted May 16, 2015 I read through some posts and it looks like I don't HAVE to swap intakes. The EGR work around sounds like just the ticket. Honestly a cel doesn't bother me as long as I know it's not a problem. Anything else I should be looking fore? Opinions welcome. Link to comment Share on other sites More sharing options...
Olnick Posted May 16, 2015 Share Posted May 16, 2015 A point of perspective . . . the CEL may not bother you as long as you know it's not a problem. But what happens if it's trying to tell you there IS a problem? Just something to think about!!! Link to comment Share on other sites More sharing options...
shoebee2 Posted May 16, 2015 Author Share Posted May 16, 2015 Point well taken. Wont the EGR work around cancle out the cel for the egr? Link to comment Share on other sites More sharing options...
Olnick Posted May 16, 2015 Share Posted May 16, 2015 I think it will. Maybe someone with more knowledge about it will confirm! Link to comment Share on other sites More sharing options...
86BRATMAN Posted May 16, 2015 Share Posted May 16, 2015 The exhaust manifold and water pump are stock. The jdm/audm market ej25d had a very turbo like exhaust routing, and thus needed the turbo style water pump to match. Use your exhaust system on the jdm motor. The egr bypass will work, just look on the forum for threads about this. I think there is one in the USRM for using a non-egr ej22 in place of an ej25d, the egr bypass will work the same as detailed in that thread. 2 Link to comment Share on other sites More sharing options...
