All our knowledge put to work for you

After nearly 4 years of trial and error, we have gathered all the fruits of our success in one place! Here are our brand new performance packages. These are intended to facilitate the purchase of your parts without worrying about having bought a wrong product.

Gold Performance Pack is for what type of person?

This package is for people who are looking for the best parts and who have the goal of pushing their vehicle to the maximum without opening the engine and putting in improved camshafts. Long tube headers are known for their efficiency if not being noisier than test pipes. Please note that these also cause exhaust gas odors, most customers tolerate the smell very well. Choose from the options and assemble your own combo.

Why don't I have more than one choice for air intake?

Since 3 inch air intakes are the best way to get maximum gains. We do not offer inferior options in terms of performance. These require reprogramming for the vehicle to work after installation.

ISR or PPE long tube headers?

The PPE long tube collectors are those that offer the best HP gain, on the other hand the price is higher than that of the ISR. Speaking of them ... they are the best quality / price ratio, failing to not offer the same gains as the PPE. On the other hand, the difference is minimal, we are talking about 3-5 HP at the wheels with a good exhaust. In addition, the PPE offer a unique purr to the engine compared to the ISR (which still sound very good).

What is a PCV Removal Kit?

When installing 3" intakes, this becomes necessary since the intakes remove the PCV. The 2 K&N filters block the oil deposits that build up in the upper plenum as standard. You can theoretically run without the PCV Delete Kit but the engine bay will get dirty faster and in the long run an oil smell will be detectable, making the 3" intake experience miserable.

Which catback option should I take?

All the options offered have a deep and strong intonation. The Gold Performance Pack focuses only on premium parts that offer the best gains without worrying about the intensity of the noise. Our favorite is the Tomei with the Tomei Y-Pipe, however... Are your ears ready for that? 😉

What is FlexFuel?

This term means that the vehicle called ''FlexFuel'' can use different fuels, in this case we use ethanol (E85). The kit includes OEM GTR injectors and a FlexFuel sensor. One of the advantages of doing business with G/Z Motorsports is the experience of our programmer. We use advanced methods so that our programming adjusts itself depending on the percentage of ethanol you add to the vehicle. This makes the use of this fuel safer and avoids random breakdowns.

How much wheel HP does the Gold Performance Pack provide?

In general we are talking about a good 350-365whp with the FlexFuel Kit and ethanol. Otherwise a very respectable 335-340whp at good old 91oct.
For your information, a VQ37VHR Manual does 265-275whp on our dyno.
This depends greatly on certain factors that we do not control.

For example:

• Temperature during the dynamometer session
• Humidity
• Engine health
• The weight of rotating masses (Wheels, Flywheel, Driving Shaft, Brake Discs)
