Minor Obstacle x 8

Solved a mystery that has been bugging me for a while. Since the swap work, i've always suspected that my flywheel bolts are too short. If they are, that's bad news for the coming turbo conversion. The extra torque might shear the threads of them and left me with bigger problem. Today, i went to check if my suspicion is correct.

Picture above was taken during the swap process. You can see there aren't many threads left from the bolts. I don't think stock bolts are only that long so i went browsing for a picture of a stock bolt and photoshopped it next to my current bolt pic which i conveniently took before it got installed. Here's the result.

Left is the shopped pic and on the center is mine. Definitely mine is too short! Probably my 4A-GE originally came from an auto trans. Flexplate bolts are shorter than flywheel's so that could be why my bolts are too short. The one to the right was a failed attempt at trying to replace the short bolt. The bolt head was too big and just bump to each other on the flywheel.

For the record, 4A-GE flywheel has 8 bolts and the bolt size is M10 x 1.25 thread pitch. Shank plus thread length should be around 26mm. Here's some measurement pic taken from Toymods.

A set of 8 new flywheels bolt would set me back around $40, excluding shipping and the labor cost to replace them. There goes my plan of cheap turbo conversion. I might as well go for a set of ARP head studs then.
