I just got my rx7 about 2 months ago. It came with a racing beat header, and supposedly rebuilt motor. It ran ok when I got it. So, I order Bonez K&N kit, custom 2.5 header back to magnaflow, Satisfied motorsports GS5 pads and shoes, new ignition coils, plugs, cap n rotor. Then I heard the "crunch" and it started shaking and idling weird, and lost alot of power. SO, I'm guessing the apex seal went. I would dump money into it and put a 13b in it, but I'm taking off for Marine Boot Camp in May, and I don't have much time or money until then, so me and the RX7 need to part. It is gunmetal color but the paint is rough, and it has a sunroof that doesn't leak I'm taking offers on this car, so anyone shoot me an offer please. email me at madskillz1599@yahoo.com, or PM me here I guess. thanks
