    engine mounts are in. passenger side looked ok but was starting to separate, driver side was completely separated. i found these 2 links helpful:

    thanks to corytomo for quickly making me a bracket for my AEM intake since i don't have power steering, as well as an EGR block off plate

    and the header is finally in! it was a breeze since it was the second time installing it not a huge difference in sound but i am getting a kind of annoying rattle/rasp around 3k rpm. other than that i love how the car sounds the way it is.



    best mod of all, recently did evo school phase 1, 2, and challenge all in one weekend!

    picked up some Bride LF-Type seat rails from jerryscherry

    the bride LF-type seat rails arrived and they've since been installed. the sonicmotor VS3 bolted up to it without issue and there are holes on the brackets to mount the seatbelt receiver and that works well too. the front is mounted at the middle of 3 holes on the brackets. if i put it on the lowest setting, there is no room for the slider handle to move and thus you can't slide the seat. this leaves the front end of the seat just about as high as it was when the VS3 brackets were bolted to the OE rails. the rear can be mounted on the lowest of the 3 holes on the bracket and that drops the top of the seat down about an inch and a half, but since the front is roughly the same spot, i basically got more reclined which I didn't really want. I would have preferred to sit more upright so that i can give my legs more room as they're really cramped and get my body closer to the wheel (more bend at the elbows preferred). the setup is not any lighter than the setup i had before. the only real benefit is that it brings the seat away from the door and no longer mashes the door card.

    if i could go back in time, i would not do this over

    so recall here's a pic of the header installed. there is a bracket built into the header that doesn't appear to go anywhere...



    so i designed a bracket and a friend of mine helped me cut and drill it



    after some final filing down by me to get it to fit the bell housing appropriately, plus some hardware from home depot, here it is installed. sorry about the poor photo quality.



    i may add a split washer between the nut and the flat washer if i get un-lazy

    have been thinking about a lightweight battery and found this thread on mnet:
    http://forum.miata.net/vb/showthread.php?t=323624

    lots of options there, plus a little more reading elsewhere, i decided on...
    Ballistic Performance Evo2 L 12-Cell LiFePO4 Battery (100-012L), 410CCA, 2.44lbs!

    new battery, stock battery (~20lbs) which i believe is the original battery and running strong, plus some brackets i designed, drilled, a friend help me cut, and my gf helped me bend.



    here's all the rest of the hardware to complete the job. some long bolts fully threaded, fender washers, bottom bracket, washer, nylon lock nuts, more washers, split washers, wing nuts. also, big thanks to corytomo for donating the battery posts! i learned when hooking the battery up that the posts are actually different sizes. who knew??



    so here is the foundation all bolted down. drilled new holes for the bolts to go through. it does not wobble at all, even when it was not yet bolted.



    view from under the car



    and here it is all done! didn't even need to extend the wires.

    Nice build you have here. I think I'll check out those batteries.

    Your next mod should be a radiator, whether it be an OEM or aftermarket is up to you. That nice green color of your radiator is the black plastic giving up the ghost. I have seen them explode at autocrosses.
