sondat Posted July 9, 2018 Report Share Posted July 9, 2018 Require 1 flywheel bolt. Converted 521 from L16 to L20b, L20 has 6 bolt pattern, not 5 like the L16. Quote Link to comment
Stoffregen Motorsports Posted July 9, 2018 Report Share Posted July 9, 2018 Junkyard or Nissan dealer. But yes, someone here on Ratsun will probably come through for you. I would replace them all, to be sure they are of the same variety. There are at least three different flywheel bolts that appeared on L motors over the years, the strongest ones coming off the L28T.

sondat Posted July 10, 2018 Author Report Share Posted July 10, 2018 First off, I apologize for posting this here but couldn’t seem to get it posted in classifieds. I will check some junk yards. If I changed all 6, are the thread patterns and sizes the same in newer Nissan’s? Quote Link to comment
Crashtd420 Posted July 10, 2018 Report Share Posted July 10, 2018 Not sure if they are the same as newer or which ones have the same threads.. You can always go with arp... they make a specific flywheel bolt and washer.... I can try to find the part number in my notes..... Quote Link to comment
sondat Posted July 10, 2018 Author Report Share Posted July 10, 2018 Looking at ARP’s web site, the closest match to a L20b is kit# 102-2803. The kit looks like 8 bolts, not 6 and don’t see the built in washer/flange like my original bolts. Kit is for Nissan 2.0L (SR20DE/DET). I will check local auto wrecker today. Thanks Quote Link to comment

Thanks Those list as m10 bolts.... I was reading somewhere that the flywheel bolts are m12x 1.25 for the L series.... that needs to be verified.. I don't think I bought a kit specific to the L series ... I couldn't find the info in my notes.. I would have to look for the package at home.... if they are in fact m12x1.25 thread this kit would work... Has bolts and the special washer, but I would make sure the length is good... Also thought I saw a Toyota had the same size flywheel bolts... Not sure what model.... that might take a bit more searching.... 1 Quote Link to comment
datzenmike Posted July 10, 2018 Report Share Posted July 10, 2018 Flywheel and flex plate bolts are different length. Quote Link to comment
Stoffregen Motorsports Posted July 10, 2018 Report Share Posted July 10, 2018 (edited) All L motors have the same thread on the flywheel bolt, but as Mike said, there are different lengths. The reason I like to use the newer bolts is for the strength, which increased as the years passed. I believe the later ones were marked with a T.
