Hi scott,
Firstly collect all you need, no point looking into a job you don't have all the stuff to do!
After that id be looking into some of the performance workshops and seeing whos done this swap before. its not particularly hard.
you could try a AE86 setup, or even adapt the R31 skyline/pintara setup like a lot of people do, but i believe both require a 14 inch rim, it would be very much a case of trying on your wheel on one of the above setups to see how it sits.
Hrmm most high/lows hid kits have only one plug so youll only need ur factory wiring but if you get a defect (likely) youll need to upgrade the wiring to run conventional bulbs
yeah you will. the biggest obstacle is wiring up a good power feed and relays to make the h4s work. if you want all four hi/low which i did this is essential.
well youd think youd be invitied to ride along in someones car if you towed it out or even offered a steer. hell knows if you were doing that for me id be giving you a drive.
maybe aim for a late jan first event? that gives you time to recover from ur wedding and me time to recover from moving house and get trailer regoed lol
