|  recently i read some thread here about lighten flywheel.. I would like to share this with everyone with what happened to my engine... I have a B18C 4.4tranny stock flywheel in my Civic SiR EK4, swap a 4.785 tranny and Toda lightweight flywheel in... I rev the new swap like before.. n tis wat happened... dead head dead CTR piston with that swap, accelaration is faster, your revs drop fast too... this swap's good for 0-60 or 0-100, but lose out on holding on to top speed... |

| stock ITR cams, springs n retainers.. CTR 81mm pistons, ITR 4.785 tranny, should be getting about a 12:1 compression...?? used to be able to rev til 9000 before the tranny swap and toda flywheel... It happened when RPM was about 8000-8200 on 3rd gear... |

| how the fuck did that happen? it almost looks like that piston got cherry red to where it was molten and slammed into the head. and how could a lightened flywheel and short tranny do that? |

 your mechanic is a retard... its not like revs are read from your speed sensor.. something else happend, i dont see how revving to 8200 would cause that, maybe revving to 9K you run the risk.. but no way changing gear ratios in the tranny is going to change your rev limit... did you maybe downshift making it rev it to 9200? | |

| sounds more like the outcome of reving an engine too high stock parts cant hold to 9000+ on a regular basis i would put the fault on over-reving looks like you had some insane valve float and it fucked everything up |

|  Those pics are of valvetrain failure. Your tranny/flywheel had nothing to do with it. |
