    Re: EJ257 Rebuild questions

    If you remember my thread from a few years ago Dave, I basically did the same thing that you want to do here. (but to a honda)

    I went with Wiseco pistons, Manley rods and ACL race bearings.

    AMCO bored my block out .020" over, honed, resurfaced, and assembled the short block to my specs... Ran about $1400 in machining and labor all said and done.

    I will be forever hesitant to have another block built in tbay. (even though mine has held up good so far *knock on wood*) Sending it out and having it professionally done by a shop that has done hundreds of high performance engines of your exact motor type is worth its weight in gold. Even if it costs $1000 more... the peace of mind is worth it in my opinion.

    But, Curtis is pretty current on the old subaru motor as of recent... maybe he can hook up up. lol

    I think the biggest thing is knowing what you need to get done at the machine shop....general boring and decking doesn't require the most talented machinist in the world but if you were getting into sleaving or plating your block you might go with a shop that does it everyday.

    If you can do all the measuring and checking clearances yourself then you'll be ok.

    Re: EJ257 Rebuild questions

    k so this may be happening... I had to drive the car to work once while my girlfriend was back from school for christmas. Anyways on the way home i noticed my A/F was bouncing around more than it usually does, didn't really thing anything of it. I stopped at a set of construction lights and it was idling like a tractor and wanting to stall out so that sucked other than that it drove fine so I made it home and it threw a ACVS code on me. I did some research and found that shitty oil can cause the solenoid for the intake timing to not work right so i flushed the oil out of it and put fresh stuff in seemed to idle fine cool! Drive it to breakfast the next day A/F started bouncing around again and idling like a tractor again so shit made it home and it started throwing misfire codes on me then. I pulled the 2 timing solenoids swapped them side to side and checked the coils and plugs. I borrowed a compression tester from shawn and checked that as well it came out 100-95 on all all 4 cylinders so its definitely low but it is pretty high mileage. After i threw it all back together the codes cleared and it idled fine but would "burble" (for lack of a better word) every once in a while and my A/F would dive. I haven't had a chance to take it for a drive since I put it back together so I'm not sure if its better. Can anyone think of anything else I should check before I expect the worst?? Got nothing but time now as Seija is back in toronto now

    Curtis...

    This may be better suited for a subie forum Dave

    But in all honesty... pull that motor and send it down to the states for a REBUILD OF EXTREME FORGE-NESS!

    Read a few how tos and watch videos on YouTube. There should be lots on pulong Subaru motors. Especially considering you might as well pull the motor to change the plugs. Damn sideways motors

    Re: EJ257 Rebuild questions

    If you end up pulling the motor you can use my hoist. Fold-able. It can fit in the back of your truck.

    Do your research and buy all the parts for 600HP and text me when you are ready for it haha

    Just get Curtis to rebuild it. He can do it while drunk, with his eyes closed and a small Asian gently cupping his balls

    Re: EJ257 Rebuild questions

    If you plan on pulling the motor out and need some help, let me know.

    Also, Have you changed and gapped your spark plugs recently? I'm pretty sure if that were to cause a misfire, it would still shoot of the same codes.
