Heat build up in the engine can be an issue, so fit an uprated radiator & oil cooling when tuning the engine to avoid this.Problem areas to look out for on the VQ35DE block. Head gaskets are different and the third generation water flow are spread across the head, whereas first and second generation were located on the left cylinder. The stock engines can handle around 400hp, but if you get stronger con rods and crank you should be good for another 300hp on top of this. (Most of the 2005-1006 engines produced 300hp) The intake Plenum was also revised for the 350Z on the VQ35HR engine in 2007 helping to raise power from the original 2003 engine from 287hp to 306hp. Typical stage 3 mods often include: Sports gearbox, Competition cam, Engine balancing, Internal engine upgrades (pistons/head/valves), Adding or upgrading forced induction (turbo/supercharger). Typical stage 2 mods often include: fuel pump upgrades, high flow fuel injector, Ported and polished head, Power/Sport clutch, Fast road cam. Typical stage 1 mods often include: Suspension upgrade (drop 28mm - 37 mm.), Lighter flywheel, Panel air filter, Engine Tunes/Remapping, Sports exhaust, Alloy wheels. Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.It is one of the most costly upgrades but provides the best gains. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power.Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.Engine Tunes - engine tuning/remapping provides the most advantage in terms of cost savings, aftermarket ECUs, and piggyback ECUs are all alternatives.Be sure to keep up with our latest YouTube content and subscribe. Please watch our video which covers the 5 principles of tuning your car. Stage 3 competition upgrades just don't work well on the road difficult in stop start traffic. Getting the best uprated mods for your planned usage of the car is a time and money saver. Typically these uprated parts are usually fitted by our members, decide how far you wish to go in your tuning project before you get going. The 350Z VQ35DE engine had a different ECU, internals were adjusted slightly and benefited from CVVTCS on the exhaust cam in addition to the intake. We've expanded this page by writing a comprehensive VQ35DE tuning guide. The electronic variable valve exhaust timing, helped control emissions and maintain power, it also had a dual path intake plenum and higher compression ratio.ĭue to the VQ35HR engines height a bonnet bulge had to be added. This VQ35HR engine was based loosely on the VQ35DE block but featured a higher power engine offering 313hp, with higher redline, more torque throughout the RPM range and most internal components were made stronger making this a good upgrade path. The 2007 VQ35HR had a higher redline and produced more peak power and had a better Torque band. Later models (2007-2009) had a VQ35HR engine block. The VQ35DE engine was fitted in the 350 and it is a fantastic engine for tuning projects.
