I have a 1991 Z24. She has 116thou. miles on her 3.1. SHe runs great and has been well taken care of. I put her up for the winter and I want to do some major work to her. Body is in good shape. I already have begun modifications to the exhaust system. Splicing off after the converter and running 2 side pipes out the drivers side. I need some tips on how to re-do the interior, and modify the engine to get better performance. I would rather not take it to a shop to do all this if possible, I would like to learn how to do it on my own. A new paint job and graphics are also on the menu. My grandmother bought this car for me before she passed away, so I would love to make this car a collecters item. Anyone that can give me any help on this would be greatly appreciated! Thanks!
