Porting stuff from Forza 3

Ok, i need some help with porting stuff from Forza Motorsport 3.
I have almost all cars from that game in .MAX format, thanks to one russian guy, who ported them to 3DSMax.
What i request: Good tutorials with porting that things to Gmod or i can send archive(s) with models and tell what need to do.
(I’m not believe that TheDanishMaster will port that, he loves requests, subscriptions and exclusive stuff). I only want props, or learn how to do it.
