Has anybody done the conversion?

lots of mixed info on the net, hoping to find someone who knows how to best get it done

from research:
- Need to grind bellhousing
- may need to use S12 CA18DE starter motor (doesn't have a housing over the throw out gear)
- Some flywheel brands are beeter than others maybe... (im looking at using a light weight fly)

i want to use the SR20DET clutch becuase it's 225mm instead of 200mm diameter, which I'm hoping means i can hold 180rwkw with an organic type clutch palte

but also read, s12 starter has the wrong number of teeth. some flywheel dont need any mods. i've read some of the specs on some flywheels and they arn't the full 225mm size

ANY CLUES?

i have a CA18DET chromemoly 5kg flywheel and a clutch is like $650 for that

or i can proabbly buy and SR20DET light fly and clutch for $1000 and sell the CA flywheel


Any suggestions for a good CA clutch etc will also be interesting
