The 03' cobra on street tires is a b!tch to launch. Most people run 13.1-12.7's bone stock.
My brother just bought an 86' turbo Z he has ordered the necessary parts to up the boost from 4 to 9 #'s and is getting 3 inch exhaust installed. Got any advice for him???

Gotta be real careful upping boost without paying attention to detonation/knock retard, fuel pressure, gas quality, timing etc. I don't have mine upped much from stock so I'm pretty safe as long as I run good gas. Most guys run turbo-link or other computer programs to read their cars for optimal tuning and to monitor the ever dreaded KNOCK. Detonation/knock can destroy a turbo engine. If you're lucky you'll just come away with a blown head gasket. I'm not familiar with the Turbo-Z or it's engine but it may have it's own specific characteristics. I know my old Typhoon wouldn't accept the same mods as my turbo 3.8's. For instance, the Sy/Ty engines didn't like the cat-convertor taken off without doing other things to the engine or it would over-boost. The GN/TTA's love the cat gone with no adjustments otherwise.
