Well...I'll definitely be looking into the silicone carbide brake pads...if I remember correctly the Porsche Carerra GT has silicone carbide pads...and as far as the injectors and turbos go....Ill see what can be done about that...one problem with the Z is the limited space it has for different types of turbos....so if given more space somehow (which i will look into) more turbo options will be available for the Z which increases the chances of finding some that are cheaper....also I believe Escort racing has some top mounting turbo intake manifolds...which to me are pretty crude looking and I will look into fabricating something similar that looks a little more streamline. At that point many many turbos options will be available...and we'll finally have room for enormous turbos like the Supra and Skyline.....of course this will inevitable cause me to fabricate to mounting brakets for certain other things in the engine bay not only to make room for such a platform but to clean the engine bay up anyway....
