LoyaleWithCheese* Posted April 30, 2017 Share Posted April 30, 2017 (edited) how is everyone? i had a jdm question. Has anyone had experience with this issue?? lately i swapped the blown engine out of my 05 forester XT for a JDM ej205 turbo. my buddy & i used the stock USDM Intake & ECU to get around Colorado emissions. After getting it done we hauled it to the Tuner where we were told the cam sensors were not reading the cams. after mapping everything the tuner said he could pickup the passenger side cam somehow when he shouldnt have been able to. they gave me the OK to drive it 30 min home. just drive it like a grandma until it was fixed. that as far as its gone, it drove great on the highway @ 60. After talking to some Techs about the problem, it was either merge the USDM & JDM harnesses so the JDM cam sensors could be used with the USDM 2.5 Intake. OR it could also be fixed by swapping the cams in the JDM engine to USDM cams so the sensors would read. i was about ready to order Kelford cams & find a shop to do the work when i called around a lil more & i was told that stock USDM cams would work just fine. has anyone worked on or know of any other issues that i could run into by putting USDM Cams in?? i'm dropping it off next week @ the shop & hoping to track down any other tweaks that would hender the finish of this engine. i hope that will fix it. any info will help thx Edited May 1, 2017 by LoyaleWithCheese* Link to comment Share on other sites More sharing options...
matt167 Posted May 1, 2017 Share Posted May 1, 2017 Is this a turbo EJ205 or a N/A SOHC EJ201,202,203? You can swap USDM 2.5 SOHC cams into a 2.0L SOHC engine, yes that will work. They are not much different though.. What you need to do is swap the crank pulley and the drivers cam pulley and then they will read right 1 Link to comment Share on other sites More sharing options...

86BRATMAN Posted May 1, 2017 Share Posted May 1, 2017 Assuming this was a forester xt, use the usdm cams, ocv's (will have to us a spacer between the ocv body and its mount point), cam sensors (will have to mod the sensors slightly to get them to sit flush in the 205 avcs heads), and full 255 intake manifold and harness. Done a few of these (and talked people through several others) and aside from tuning the ecu there are absolutely no issues. 2 Link to comment Share on other sites More sharing options...

We ground away part of the casting on & around the JDM head & cam sensor location & nearly impossible without the intake off. we also deleted the TGV's while the intake was off. We werent able to get a good O-ring to fit in the hole so we did our best to get 1 close enough & trim it down to fit the cam sensor hole. We temporarily FUJI Bonded the senors on because the hole for the bolt would not line up & was off by just a smidge! I now know that the little metal bushing/gromet inside of the plastic that the USDM sensor is made of needs dremeled to get enough clearance to get the small bolt in to hold the sensor for good! Yes, once the work is complete it will not go anywhere besides a tuner. what would you use for a spacer on the OSV mounting point. i cant really picture where a spacer would go & why. thx for the help Link to comment Share on other sites More sharing options...
86BRATMAN Posted May 1, 2017 Share Posted May 1, 2017 On one I used nuts from a spare driveshaft, the ones that hold it to the rear diff or at the split of the two halves lol. It was what I had laying around and it fit perfectly. You could also use a group of small washers. Just anything really, if you allow the metal body of the ocv to bend it will end up leaking oil. 1 Link to comment Share on other sites More sharing options...
LoyaleWithCheese* Posted May 7, 2017 Author Share Posted May 7, 2017 I was talking to a tuner the other day & he mentioned that the sensor hole location on the 205 vs the heads from the 2.5 is just a lil different. He was conserved that the sensor might only read part or 1/2 of the timing marks on the cams & would give a constant 5 volt reading instead of dropping voltage between the marks. I took my forester to Suba Performance on Friday. I have the 2.5 cams that I'm taking to them on Monday. I'm crossing my fingers I don't have to buy Kelford cams to fix the issue Link to comment Share on other sites More sharing options...
86BRATMAN Posted May 7, 2017 Share Posted May 7, 2017 With a few mods to the sensor itself, mainly the bolt hole and shaving the side slightly so it clears the casting of the head and sit flush they will read perfectly fine with the stock ej25 cams.
