wow dont know where u been looking for boxes, can u provide a link to these cheap boxes? all the ones ive seen on here have been $4500+ considering its about $8000 brand new
import monster has some for $4500 delivered
new twin plate clutches go for anywhere betwwen $1500 for a cheap one up to $2500 for nismo copermix
u want to race so a new diff is required say about $1800- 2200 for a 1.5/ 2 way
drive shaft will be more than your quoted 1-200
will need to be ballanced also
oils, theres another $200 or more for diff and box
so far ive added up ull be over $8000.
have u driven a six speed before and did it live up to everything that u say it will?
do u have a hoist also? gear boxes are heavy n i wouldnt attempt to install one only on jacks.
you honestly have to weigh up if its worth it? u may do all the work n find out its not all u make it out to be.
listen to the people on here, they have tones of experience and have learnt lessons from others, all we are trying to do is let u know that its not worth the effort
