Does anybody have any recommendations for a first time modification for a 95 SC 400. I would like to start with maybe the air intake and work my way up from there. I have owned this stock beauty for five years and I have 150,000 miles on her so I don't want to do any thing to drastic, but I would like to get a few more horse's out of her and still pass emissions. Also, does anybody know anything about computer chip replacements for the SC 400.

 

Turbo the SC400 and use AEM EMS . It won't be a "drastic" process if you let a reputable/experienced shop do all the work. All you have to do is drop the car off and pick it up several days later and it's all done .

If you have the time BFI3 is the cleanest looking in my opinion.
