May 15, 2013 SHARE

By now, you’ve seen us highlight parts time and time again for the more popular Nissan engines, such as the SR20DET (or KA), but we know there are just as many enthusiasts out there who require more power out of their 350Z, 370Z, G35 or G37—that’s where this guide comes in handy. Here are some of the best engine hard parts you can find, as well as forced induction kits that’ll seriously launch your VQ35DE or VQ37DE where you’d like it to go. Remember that most Nissan parts will also fit Infiniti platforms but it’s best to double-check with the manufacturer.
