Rear counterweight for the FD
hi Guys,
a few months ago i ordered a rear counterweight for my Fd because i wanted to fit it with a light weight flywheel. i ordered the N351-11-521 counterweight and i received a counterweight with the N3Y2-11-52X part number. for my litle research i found that this counterweight is for the 86-88 model. what is going on? do the 86 counterweight fits the fd or it is a mistake? can someone please let me know what the two counterweight weights? thanks i apreciate any help achiles |
Do not put the S4 CW on your FD engine. It is not weighted the same and will cause your rotating assembly to be out of balance.

Mazdatrix.com has a guide to all the counterweights with pictures of them so you can tell them apart.
Hit up the 2nd gen for sale section, the '89-91 auto tranny counterweight is the same as the FD's counterweight and they go cheaper :). Dale |

Or get a micrometer and measure the flange width to be certain....
