VQ37VHR 400HP Package

starstarstarstarstar 5/5 - (1 Reviews)
Fits models: 370Z / G37

Product Description

The Z1 Motorsports VQ37VHR 400HP Package includes tested and proven components necessary to maximize the output of your naturally aspirated 370Z or G37. 

After a over a year of development and extensive dyno testing on multiple cars, we have released an intake manifold modification that complements our mid length exhaust header design which produces more peak power (while maintaining power under the curve) than any other products on the market we've tested including more expensive long tube headers and competitors intake manifold upgrades.  

Nissan advertises 332 horsepower (350 for the Nismo) as the output of the VQ37VHR engine found in the 370Z & G37.  Auto manufacturers rate horsepower at the flywheel.  From our testing, new stock 370Zs produce around 280 rear wheel horsepower on a DynoJet, which is consistent with Nissan's claims assuming 15% drivetrain loss.  Given this drivetrain loss, 340 rear wheel horsepower equates to the engine producing 400 horsepower.  

In conjunction with a Z1 Cold Air Intake Kit and a quality high flowing exhaust system the Z1 VQ37VHR 400HP Package can produce 340+ rear wheel horsepower on a DynoJet on 93 octane fuel when properly tuned with Uprev Engine Management.  We have not included the intake, exhaust, or engine management systems in this package because many people have already purchased these items.  We recommend installation and tuning through Z1 Motorsports.

Note: When installing on 370Z / G37 models, the drivers side motor mount bracket will need to be clearanced. This is a minor modification that can be completed in a short time with the proper tools.

This package includes the following components:

Headers will not fit AWD G35X or G37X models.

A $250 refundable core charge applies to the intake manifold.  If the core manifold is received broken or damaged no refund will be given.  Pack carefully.   View our core return form and policy

These have been found to not fit RHD models without modification to clear the steering knuckle. We will not guarantee fitment with RHD.
