    60 or 67mm for 1jz

    I"m curious which turbo you guys think would be the most responsive and have better spool, a 60 trim with .82 ar or a 67 trim with a .70 ar? I'm trying to decide on which dm kit to get and need help picking which turbo and hotside to go with. Thanks in advance.

    it definately could be now that i can't even run at stock fuel without it cutting out. Have to run it at -5 percent for it not to cut out. I have a walbro in my wrx that i might take out today and put it and see what it does.

    ok here is the first vid with safc on all stock settings. View My Video I did a pull w/ -5% fuel taken out. It did not cut out once. anything over -5% taken out it cuts out bad. I tried +5% and it was even worse. I used to be able to run +10% all the time with no problems.

    i swapped ecu's with an auto 1jz which i was told are the same but my car would barely idle. Makes me think my ecu could be modded or reflashed when i got it. The swap came with a 3inch downpipe and intake and it looked like it had previously had a piggyback wired in. I think i might have...
