on the wiring, i was told 800-1000 by a local shop who has done MANY subaru motors in other cars, and full sti swaps into non wrx cars ect ect. he said that about 1000 would get all the wiring for the whole setup, wired into the stock obd2 WRX ECU, ect. should I expect it to be much less? if i could take that expense out of it, i will, but the fact that wiring harnesses, and all that **** just absolutely boggle me, id like to leave it up to someone else. i plan to wire in a stock OBD2 port so I can read fault codes, and also, plug in the obd2-usb connector, and tune with it. go to
www.openecu.org (i think thats the name of it) and take a look at what has been done. people have cracked the subaru ECU, and are able to basically tune it for free. it takes about 79 bucks for the usb-obd2 connector harness!!! thats the hugestbreak through ever really, with the WRX ecu, because untill now, tuning that ecu would cost upwards of 1000 bucks.
i would be happy to give you lots of feedback on the subaru motor you plan on buying, Ive got alot of built up knowledge from my days as a subaru guy. email me at
geezer_jay@hotmail.com if you would like any other information. I love exchanging information, and really need lots of help getting my bug to the point i want it at.
