Safely increase the output of your stock TTZ almost 100 hp!
In addition to the items outlined here in the 400 HP Twin Turbo Z Power Pack, Z1 Recommends adding Downpipes and Testpipes (Off Road Use Only) to increase the power output further.
After you have the 400 hp pack in place and preferably a free flowing exhaust with downpipes and testpipes the limiting factor becomes fuel delivery. Stock injectors just can't supply enough fuel to produce more than ~350 rwhp. Your next big step should be upgraded fuel injectors after the 400 hp Z pack. Lightweight Pullies, Lightweight Flywheel, and Dual Intakes can increase the power output of the 400 HP Power Pack as well.
Many customers go ahead and take it to the next level in one step with the one of our higher power packs that include larger injectors, turbos, etc. Whatever your goals may be, we can help. Feel free to contact us for advice and additional information.
Installation available at Z1 Motorsports starting at $395. Includes ConZult diagnostics, trouble code elimination, ignition timing verification, and more. Test driving is also performed to insure proper performance and reliability.
$300 Core Charge applies to ECU - View our Core Return Policy and Form. Please note: Form MUST be included with all Core Returns.
When selecting the Z1 PG Exhaust you must either modify the existing catalytic converters or use testpipes to bolt correctly to the 3" H-Pipe.
