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.

What type of person is the Silver Performance Pack for?

This package is for people who are looking for a good HP gain and who care a little less about the intonation of their exhaust. Long tube headers are known for their efficiency if not being louder 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.

Which air intake option should I take?

K&N Drop-in filters are the cheapest and most effective way to get maximum gain. Some manufacturers make 3-inch air intakes for the Q50 with VQ37VHR, but these have too much angle and therefore the airflow is negatively affected. The simple K&N filters are much better than any style intake: Injen, Stillen, AFE Power, AEM... ect. The models mentioned are much more expensive and offer no real gain compared to the K&N Drop in filter.

What are ISR inlets used for?

Better airflow, the stock inlets have too many unnecessary curves and this affects the amount of air that enters the engine. The ISRs are smooth and provide maximum airflow.

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).

Which catback option should I take?

The very popular Invidia Gemini exhaust line creates a perfect tune and has a moderate sound, this one offers good HP gains but since the sound is moderate the airflow is also a little more moderate. Tomei, Motordyne or ARK exhausts are legendary in combination with long tube headers, literally the two exhausts that bring out the VQ37VHR's intonation the best.

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 Silver Performance Pack provide?

Generally we are talking about a good 320-330whp. Add 15-25whp for results with FlexFuel & ethanol.
FYI, a 2014-2015 Q50 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)
  
  **ALL PARTS IN THIS PERFORMANCE PACK ARE FOR OFF-ROAD USE ONLY**
  
  

PLEASE NOTE: All results shown in our Performance Packs have been achieved using a reprogramming. This is not included in the price, you can access our price list for tuning in our section: Dynamometer Reprogramming
