turbo 6port gsl-se rotors
 

i made a turbo kit for my 86 6port i am in the process of rebuilding it and stumbled on the fact that gsl-se's have 3mm. i was wondering if anyone has used them in a s4 motor and if they have, or if u can, can i use my ecentric shaft with my counter weights because i also heard they weigh a little more. anyone?

No, you can't use the same counter weights, either front or rear ones.

what do i have to do to use the gsl se rotors?

Change the counter weights to GSL-SE items I assume.. :)

IIRC the GSLSE rotors are heavier than the 86-88 ones.. Yes 3MM.. but they are heavier I believe.. you may be better off going with the stock 6-port rotors and just fresh seals and correct timing.. and not too radical boost.
Coure... if you run radical boost or timing.. the 3MM will do you no good either :D
