GTO & G8 GXP Performance Parts

 

For the highest quality in performance we dyno test all components such as intake, throttle body, headers, and exhaust systems to make sure what we install on your car is the best in the market. We have your heads ported to the highest standard in the market or use after market heads such as All Pro which is a leader in the industry. All of our cam shafts are custom ground and are tailored to your needs. We want to make sure that you get your money's worth and the performance you are looking for.

 

 

LS6 Ported Heads

These CNC ported LS6 heads, which flow 313 cfm at .600 lift would be great upgrade to your GTO's engine. We have had gains as much as 40-50 rear wheel hp from these heads!

 

 

All Pro Heads

If you are looking for the absolute best with the highest flowing numbers, the "All Pro" Heads would work great with larger displacement LSX engines such as the 6.2 in the G8 and GXP.

 

 

Stroker Engines

We don't have to tell you that cubic inches is cubic power and that dictates to torque. To get torque you need cubic inches. You can add a Stroker Engine to any of our systems to increase the potential of your GTO or G8 engine. In layman terms, "Why make the engine work harder?"

 

 

Ported Throttle Bodies

We believe that the throttle body air flow is an important factor in the engine's ability to breath. Porting a factory GTO or G8 throttle body eliminates some of the restrictions in the casting and the throttle blade which in terms will help the flow of air into your engine. With additional modifications such as heads and camshaft, this modification will benefit the performance of your engine. For larger engines we recommend after market performance LSX throttle bodies specific to the application.

 

 

American Racing Headers

We want to welcome American Racing Headers to our new line of exhaust systems. The quality and workmanship of their headers and X-pipe meets our high standards. Recent tests of their headers on a G8 GXP netted us 30 horsepower and 25 lb/ft of torque! The new ZR1 Corvette and LSA equipped CTS-V produce even more showing a monstrous gain of 55 horsepower and 50 lb/ft of torque!

 

 

Pneumatically Operated Nitrous Oxide Systems

Up to this point nitrous oxide was not part of our Pontiac GTO / G8 performance program. But with our company research, we have found the solution for reliable LSX nitrous systems with extreme potential using pneumatic operated technology. We build the nitrous systems using these pneumatic solenoids, that can be tailored to your needs. These solenoids have had zero failure rate. Another benefit of this solenoid is they can be manually operated or if activated electronically up to 4 stages will draw only 1.2 amps. 150 psi of C02 line pressure will assure a fast and reliable solenoid operation.
