    new headers

    "Tuned Header" is specific pipe lengths/diameters to produce power in a certain rpm band ;)

    pulled over 1.07 g's today in my car

    Needs to be done on a skid pad under controlled repeatable conditions to be valid ;) "sustained" will give different results depending on radius.

    tach problems, one more time....

    Using an NA Tach here Mark, when I went standalone I had to take the tach to an instrument builder to have it "tuned" so it was happy with the Tach signal from the new ECU. Turns out Toyota tachs are very fussy and will only read in a narrow range.

    installed new clutch, vibration problems

    Most machine shops have a balancer? (at least here they do)

    O.E.M/Factory .05 over pistons 7mgte

    LMAO even the biggest oversize will add very little capacity to a 7M ;) (hence power) I'd put your numbers down to a good build with correct specs :)

    new headers

    x2 this has always been my understanding of the distinction between the two.

    O.E.M/Factory .05 over pistons 7mgte

    Ahhh I see! Should be a +20 thou motor then! :)

    This may be so on a motor that's not 0 balanced ie:454 chev but ours are so he's feeding you incorrect information. If the Flywheel and Pressure plate have been balanced as an assembly soon as you change either part it needs to be done again.

    O.E.M/Factory .05 over pistons 7mgte

    Yep correct but as always physically measure them to be 100% sure! (the machinst should do this before touching the block)

    O.E.M/Factory .05 over pistons 7mgte

    .05mm = 1.9 thou If it's a OEM piston it's marked in metric.

    O.E.M/Factory .05 over pistons 7mgte

    I've never seen a 2 thou oversize piston for anything.

    O.E.M/Factory .05 over pistons 7mgte

    Stamped .5 would be half a mm or +20 thou.

    Need help with 1.5jz build

    Mark: I'd like to see the maps in use when it died. Anything else is useless. Motor's don't just eat parts for no reason and it would be nice for J to have a 100% answer so it doesn't happen again.

    George: This is why I asked to see the maps, all this speculation is useless without some data/evidence to go on.

    Hey guys

    Michelle: You can do better :D Welcome to the insanity!

    Need help with 1.5jz build

    J: Ok if you're sure it's never leaned out on power that narrows it down some. Bent/stuck/incorrectly adjusted valve is my guess. Can you post your fuel and ignition maps? (hi res screenshots will do)
