Ok update not much but got the sunroof working and all electronics. I will be using a gtr gauge cluster (oil,volt snd boost) it it's perfectly where the cd player would go. I'm almost ready to install dummy motor is I can make all the mounts needed also get the electrics sorted so it's ready to run. Iv picked up a m3 LSD diff that is extremely tight so that will go in soon. As for having to modify the sump I'll be customizing a 25 one with a new pickup.
