I am building a Tamiya GT-2. The base kit is the Taisan kit. so far I have removed the front bumper in preparation of a new resin nose. Removed most body details like hood pins, antenna base, windshield wiper posts etc.. The specific car I am building to replicate has a lot of changes to air flow for cooling. Vents have been added behind the front wheels. On the back bumper section I have cut slots on each side and placed holes on the back of the car. Still more body changes to make before adding the resin nose but it is going well so far. Chassis is mostly complete and waiting for test fitting of interior parts. I will be making some changes to the interior from the Tamiya kit but they are mostly small detail items such as different fire extenguisher, battery box, dash parts, console etc..
