I am not.concerned with friction surface diameter but outer diameter... I have a custom built 7.25" twin/triple plate flywheel for my SR but I am currently in the middle of a 700rwhp vg30dett converted to single Turbo build for my s13. I know the tt flywheel is 11.9" of at the ring gear and I know the SR is 11.8". If the tenth of an inch is a big.deal I will just slot the starter holes... as I already have my triple plate setup and am hoping to use it for this build. I am not adverse to fabrication and machine work.
Thanks
