Here is the motor with it's Toda pistons before the tragedy:


After an unfortunate 3-2 shift at 9,000 rpm


Finally, after Dan Benson resleeved the motor and IB Jeff hooked me up with some pistons


Car is up and running as strong as ever. Time for a trip to the dyno

Yes, hit second instead of 4th. I figure the engine hit at least 12,000 rpm.

It is funny how the piston hole is the perfect shape of the number 1.
Anyway, that is terrible. Hope the new motor works out well for you.

how long did you run the motor after the mis shift? or did it just die right away.

From the looks of it, death was instantaneous

i've seen plenty of burned and shatered pistons before, and to me it looks like he drove it home, then to the bank and then to benson's, i'm suprised the wrist pin didn't pull out and shater the piston,
ohh well the new motor looks awsome

lol. I wish. I am down to only three blocks.
Two for the Civic and the motor pictured above for my Integra. And I only have two good heads left, three if you count the one Brad has. The head that was on the car when I mis-shifted is scrap.
And you know I will post numbers when I hit the dyno, Jason

Death was instantaneous. Huge cloud of smoke and the engine died. Would not crank. Clutch was toast too-would not shift. Was in South Central LA when it happened

Looks like the we-todd salute to me! Man that is one ugly piston.

A rev limiter is no use on a miss-shift. The ole motor looks good as new though.

Mechanical over-rev. Shifted from 3rd to 2nd. Rev limiter only cuts fuel, while going into the wrong gear puts the weight of the car into the over-rev. I've done it, probably most road racers have at one point
