EJ205 into GF6
I've owned a few early model STis. Built a few EJ's for said cars and done my share of performance automotive work but I'm venturing into a project a little above how intricate my past forays have been. I've since sold my last two at the behest of a lady who is since out of the picture and I'm really wanting another EJ rumble box for the DD. I bought a 1995 sports wagon EF6 for 400$ from a friend and have since swapped/replaced a few parts(JDM STI struts, wheel bearings, all suspension bushings, seats, ) and the motor has a gaggle of miles and needs replaced. Needs? I want to replace it I should say. I have a 2002 USDM long block in the garage that needs rebuilt. Complete with all accessories/turbo/etc. I also have access to an 02 ECU. I also am going to run this gearbox until it explodes just for fun.
My question is how far off am I from being able to drop this in sans the swapping of ECUs if I am non-AVCS. As far as I remember the 02' has TGV's but those will be gone and CEL tuned out. I'm assuming there a multitude of wiring issues I'm approaching-connector compatibility, wiring orientation, and I'm sure other things. It would be good to get some thoughts and opinions. I'm stubborn and severely overconfident in everything I do and have another 2j/e46 track car project that is taking all my money so it has to be a cheap DD-but either way its going down. Any help is much appreciated. Cheers!

i belive it wil drop right in, but you will need a turbo cross member to drop into the gf gc or gg body, and the wriitng is the other big problem, I know you can send your harness to Iwire and he will merge them together but im sure you can do it yourself just a matter of having the pins out and the diagrams

along with the turbo engine and cross member.
sounds like all u will need is the turbo engine side harness, turbo bulkhead harness and the ecu and u should be set. |

I think I’ve got the wiring path just about squared and am
About to get started on the melding of cobwebs. Does anybody know crossmember compatibility across the different models? Will the member for the same model of WRX my EJ came from bolt to the frame of my 95’? Cheers |

Update
Trying to keep it cheap and simple-reliability is for my other cars
I've got the motor in the chassis after splitting it and adding some forged bits. I've went the poor person with too much time on his hands route and I'm trying to reuse everything I can in the old harness without doing full on merge, just using the 2.0 engine harness and adding wires and a relay where needed. I've added the runs to the ECU for the newer Denso style MAF, two coils as the old 1.8 was batch fire, sensor power for the newer TPS, IACV, and MAP and a few others as I go along with my test bench and OHM test net to reuse what bulkhead harness stuff I could from the 1.8. I'll also be stuck with having a simple indicator I\O light for overheating conditions, as I'm simply not going to pull the dash to make the old style gauge work or replace it- I'm far too lazy and this is already far too much wiring ha. One question I have that is a little beyond my understanding of automative wiring is with the ignition ground setup and the whole ground setup to the ECM. The grounds are grouped into their respective connotations on the pinout I have. But the way Subaru routed everything does not make complete sense to me, coming from industrial automation type stuff. I wonder- Is it paramount that each group (injectors, ignition, Sensors, etc) ALL are routed correctly to their designated pins? I think I have everything figured but this is a little above my knowledge, which can be lacking in all facets of life anyway, and I wonder how this might affect start up/break in. I have an amalgam of wiring diagrams and pinouts in front of me as I am working with an OBD1 chassis, JDM EJ205 and an ECU of a different year of which I am using the plugs for the pinout until I start re-pinning them after everything is hopefully operable. Secondly I have a JDM forester ECU (for AVCS) from what I believe is early 2002 that I'll be adding whatever ROM I decide onto and I've been working off a JDM FSM for the engine harness but I couldn't find a JDM ECU pinout so I've been using a 2002 USDM WRX pinout- What are the chances that the ECU pinouts are completely different for those years in different markets? I'm of course not talking color, but actually pin locations. I'm reeeaaaaaallly hoping the answer is they are not different, but if anyone with more knowledge and a larger brain could chime in on why I'm an idiot for not thinking about that sooner and what issues I could have, that'd be great. I welcome all opinions and if there is another place this would fit better please let me know. I'm just a NW Redneck that hangs things from ceilings in arenas, I'm always down to learn more in this realm. Jah A pic of my disaster- |
