1M has the SAME manual trans as a N55 6MT has. Go to RealOEM.com to confirm that.
The 1M has a different flywheel (lighter) and center drive shaft and rear acles are all different though.
IF you are going to BEAT on your car and mod it away... you better be prepared to PAY for the repairs COD.
And... PLEASE use paragraphs next time. Your post was kind of painfull to read thru.
